Tags Share this article 8/28/23 Published Like all modern cloud providers, Amazon adopts the shared responsibility model for cloud security. Amazon guarantees secure infrastructure for Amazon Web Services, while AWS users are responsible for maintaining secure configurations. That requires using multiple AWS services and tools to manage traffic. You’ll need to develop a set of inbound rules for incoming connections between your Amazon Virtual Private Cloud (VPC) and all of its Elastic Compute (EC2) instances and the rest of the Internet. You’ll also need to manage outbound traffic with a series of outbound rules. Your Amazon VPC provides you with several tools to do this. The two most important ones are security groups and Network Access Control Lists (NACLs). Security groups are stateful firewalls that secure inbound traffic for individual EC2 instances. Network ACLs are stateless firewalls that secure inbound and outbound traffic for VPC subnets. Managing AWS VPC security requires configuring both of these tools appropriately for your unique security risk profile. This means planning your security architecture carefully to align it the rest of your security framework. For example, your firewall rules impact the way Amazon Identity Access Management (IAM) handles user permissions. Some (but not all) IAM features can be implemented at the network firewall layer of security. Before you can manage AWS network security effectively , you must familiarize yourself with how AWS security tools work and what sets them apart. Everything you need to know about security groups vs NACLs AWS security groups explained: Every AWS account has a single default security group assigned to the default VPC in every Region. It is configured to allow inbound traffic from network interfaces assigned to the same group, using any protocol and any port. It also allows all outbound traffic using any protocol and any port. Your default security group will also allow all outbound IPv6 traffic once your VPC is associated with an IPv6 CIDR block. You can’t delete the default security group, but you can create new security groups and assign them to AWS EC2 instances. Each security group can only contain up to 60 rules, but you can set up to 2500 security groups per Region. You can associate many different security groups to a single instance, potentially combining hundreds of rules. These are all allow rules that allow traffic to flow according the ports and protocols specified. For example, you might set up a rule that authorizes inbound traffic over IPv6 for linux SSH commands and sends it to a specific destination. This could be different from the destination you set for other TCP traffic. Security groups are stateful, which means that requests sent from your instance will be allowed to flow regardless of inbound traffic rules. Similarly, VPC security groups automatically responses to inbound traffic to flow out regardless of outbound rules. However, since security groups do not support deny rules, you can’t use them to block a specific IP address from connecting with your EC2 instance. Be aware that Amazon EC2 automatically blocks email traffic on port 25 by default – but this is not included as a specific rule in your default security group. AWS NACLs explained: Your VPC comes with a default NACL configured to automatically allow all inbound and outbound network traffic. Unlike security groups, NACLs filter traffic at the subnet level. That means that Network ACL rules apply to every EC2 instance in the subnet, allowing users to manage AWS resources more efficiently. Every subnet in your VPC must be associated with a Network ACL. Any single Network ACL can be associated with multiple subnets, but each subnet can only be assigned to one Network ACL at a time. Every rule has its own rule number, and Amazon evaluates rules in ascending order. The most important characteristic of NACL rules is that they can deny traffic. Amazon evaluates these rules when traffic enters or leaves the subnet – not while it moves within the subnet. You can access more granular data on data flows using VPC flow logs. Since Amazon evaluates NACL rules in ascending order, make sure that you place deny rules earlier in the table than rules that allow traffic to multiple ports. You will also have to create specific rules for IPv4 and IPv6 traffic – AWS treats these as two distinct types of traffic, so rules that apply to one do not automatically apply to the other. Once you start customizing NACLs, you will have to take into account the way they interact with other AWS services. For example, Elastic Load Balancing won’t work if your NACL contains a deny rule excluding traffic from 0.0.0.0/0 or the subnet’s CIDR. You should create specific inclusions for services like Elastic Load Balancing, AWS Lambda, and AWS CloudWatch. You may need to set up specific inclusions for third-party APIs, as well. You can create these inclusions by specifying ephemeral port ranges that correspond to the services you want to allow. For example, NAT gateways use ports 1024 to 65535. This is the same range covered by AWS Lambda functions, but it’s different than the range used by Windows operating systems. When creating these rules, remember that unlike security groups, NACLs are stateless. That means that when responses to allowed traffic are generated, those responses are subject to NACL rules. Misconfigured NACLs deny traffic responses that should be allowed, leading to errors, reduced visibility, and potential security vulnerabilities . How to configure and map NACL associations A major part of optimizing NACL architecture involves mapping the associations between security groups and NACLs. Ideally, you want to enforce a specific set of rules at the subnet level using NACLs, and a different set of instance-specific rules at the security group level. Keeping these rulesets separate will prevent you from setting inconsistent rules and accidentally causing unpredictable performance problems. The first step in mapping NACL associations is using the Amazon VPC console to find out which NACL is associated with a particular subnet. Since NACLs can be associated with multiple subnets, you will want to create a comprehensive list of every association and the rules they contain. To find out which NACL is associated with a subnet: Open the Amazon VPC console . Select Subnets in the navigation pane. Select the subnet you want to inspect. The Network ACL tab will display the ID of the ACL associated with that network, and the rules it contains. To find out which subnets are associated with a NACL: Open the Amazon VPC console . Select Network ACLS in the navigation pane. Click over to the column entitled Associated With. Select a Network ACL from the list. Look for Subnet associations on the details pane and click on it. The pane will show you all subnets associated with the selected Network ACL. Now that you know how the difference between security groups and NACLs and you can map the associations between your subnets and NACLs, you’re ready to implement some security best practices that will help you strengthen and simplify your network architecture. 5 best practices for AWS NACL management Pay close attention to default NACLs, especially at the beginning Since every VPC comes with a default NACL, many AWS users jump straight into configuring their VPC and creating subnets, leaving NACL configuration for later. The problem here is that every subnet associated with your VPC will inherit the default NACL. This allows all traffic to flow into and out of the network. Going back and building a working security policy framework will be difficult and complicated – especially if adjustments are still being made to your subnet-level architecture. Taking time to create custom NACLs and assign them to the appropriate subnets as you go will make it much easier to keep track of changes to your security posture as you modify your VPC moving forward. Implement a two-tiered system where NACLs and security groups complement one another Security groups and NACLs are designed to complement one another, yet not every AWS VPC user configures their security policies accordingly. Mapping out your assets can help you identify exactly what kind of rules need to be put in place, and may help you determine which tool is the best one for each particular case. For example, imagine you have a two-tiered web application with web servers in one security group and a database in another. You could establish inbound NACL rules that allow external connections to your web servers from anywhere in the world (enabling port 443 connections) while strictly limiting access to your database (by only allowing port 3306 connections for MySQL). Look out for ineffective, redundant, and misconfigured deny rules Amazon recommends placing deny rules first in the sequential list of rules that your NACL enforces. Since you’re likely to enforce multiple deny rules per NACL (and multiple NACLs throughout your VPC), you’ll want to pay close attention to the order of those rules, looking for conflicts and misconfigurations that will impact your security posture. Similarly, you should pay close attention to the way security group rules interact with your NACLs. Even misconfigurations that are harmless from a security perspective may end up impacting the performance of your instance, or causing other problems. Regularly reviewing your rules is a good way to prevent these mistakes from occurring. Limit outbound traffic to the required ports or port ranges When creating a new NACL, you have the ability to apply inbound or outbound restrictions. There may be cases where you want to set outbound rules that allow traffic from all ports. Be careful, though. This may introduce vulnerabilities into your security posture. It’s better to limit access to the required ports, or to specify the corresponding port range for outbound rules. This establishes the principle of least privilege to outbound traffic and limits the risk of unauthorized access that may occur at the subnet level. Test your security posture frequently and verify the results How do you know if your particular combination of security groups and NACLs is optimal? Testing your architecture is a vital step towards making sure you haven’t left out any glaring vulnerabilities. It also gives you a good opportunity to address misconfiguration risks. This doesn’t always mean actively running penetration tests with experienced red team consultants, although that’s a valuable way to ensure best-in-class security. It also means taking time to validate your rules by running small tests with an external device. Consider using AWS flow logs to trace the way your rules direct traffic and using that data to improve your work. How to diagnose security group rules and NACL rules with flow logs Flow logs allow you to verify whether your firewall rules follow security best practices effectively. You can follow data ingress and egress and observe how data interacts with your AWS security rule architecture at each step along the way. This gives you clear visibility into how efficient your route tables are, and may help you configure your internet gateways for optimal performance. Before you can use the Flow Log CLI, you will need to create an IAM role that includes a policy granting users the permission to create, configure, and delete flow logs. Flow logs are available at three distinct levels, each accessible through its own console: Network interfaces VPCs Subnets You can use the ping command from an external device to test the way your instance’s security group and NACLs interact. Your security group rules (which are stateful) will allow the response ping from your instance to go through. Your NACL rules (which are stateless) will not allow the outbound ping response to travel back to your device. You can look for this activity through a flow log query. Here is a quick tutorial on how to create a flow log query to check your AWS security policies. First you’ll need to create a flow log in the AWS CLI. This is an example of a flow log query that captures all rejected traffic for a specified network interface. It delivers the flow logs to a CloudWatch log group with permissions specified in the IAM role: aws ec2 create-flow-logs \ –resource-type NetworkInterface \ –resource-ids eni-1235b8ca123456789 \ –traffic-type ALL \ –log-group-name my-flow-logs \ –deliver-logs-permission-arn arn:aws:iam::123456789101:role/publishFlowLogs Assuming your test pings represent the only traffic flowing between your external device and EC2 instance, you’ll get two records that look like this: 2 123456789010 eni-1235b8ca123456789 203.0.113.12 172.31.16.139 0 0 1 4 336 1432917027 1432917142 ACCEPT OK 2 123456789010 eni-1235b8ca123456789 172.31.16.139 203.0.113.12 0 0 1 4 336 1432917094 1432917142 REJECT OK To parse this data, you’ll need to familiarize yourself with flow log syntax. Default flow log records contain 14 arguments, although you can also expand custom queries to return more than double that number: Version tells you the version currently in use. Default flow logs requests use Version 2. Expanded custom requests may use Version 3 or 4. Account-id tells you the account ID of the owner of the network interface that traffic is traveling through. The record may display as unknown if the network interface is part of an AWS service like a Network Load Balancer. Interface-id shows the unique ID of the network interface for the traffic currently under inspection. Srcaddr shows the source of incoming traffic, or the address of the network interface for outgoing traffic. In the case of IPv4 addresses for network interfaces, it is always its private IPv4 address. Dstaddr shows the destination of outgoing traffic, or the address of the network interface for incoming traffic. In the case of IPv4 addresses for network interfaces, it is always its private IPv4 address. Srcport is the source port for the traffic under inspection. Dstport is the destination port for the traffic under inspection. Protocol refers to the corresponding IANA traffic protocol number . Packets describes the number of packets transferred. Bytes describes the number of bytes transferred. Start shows the start time when the first data packet was received. This could be up to one minute after the network interface transmitted or received the packet. End shows the time when the last data packet was received. This can be up to one minutes after the network interface transmitted or received the data packet. Action describes what happened to the traffic under inspection: ACCEPT means that traffic was allowed to pass. REJECT means the traffic was blocked, typically by security groups or NACLs. Log-status confirms the status of the flow log: OK means data is logging normally. NODATA means no network traffic to or from the network interface was detected during the specified interval. SKIPDATA means some flow log records are missing, usually due to internal capacity restraints or other errors. Going back to the example above, the flow log output shows that a user sent a command from a device with the IP address 203.0.113.12 to the network interface’s private IP address, which is 172.31.16.139. The security group’s inbound rules allowed the ICMP traffic to travel through, producing an ACCEPT record. However, the NACL did not let the ping response go through, because it is stateless. This generated the REJECT record that followed immediately after. If you configure your NACL to permit output ICMP traffic and run this test again, the second flow log record will change to ACCEPT. azon Web Services (AWS) is one of the most popular options for organizations looking to migrate their business applications to the cloud. It’s easy to see why: AWS offers high capacity, scalable and cost-effective storage, and a flexible, shared responsibility approach to security. Essentially, AWS secures the infrastructure, and you secure whatever you run on that infrastructure. However, this model does throw up some challenges. What exactly do you have control over? How can you customize your AWS infrastructure so that it isn’t just secure today, but will continue delivering robust, easily managed security in the future? The basics: security groups AWS offers virtual firewalls to organizations, for filtering traffic that crosses their cloud network segments. The AWS firewalls are managed using a concept called Security Groups. These are the policies, or lists of security rules, applied to an instance – a virtualized computer in the AWS estate. AWS Security Groups are not identical to traditional firewalls, and they have some unique characteristics and functionality that you should be aware of, and we’ve discussed them in detail in video lesson 1: the fundamentals of AWS Security Groups , but the crucial points to be aware of are as follows. First, security groups do not deny traffic – that is, all the rules in security groups are positive, and allow traffic. Second, while security group rules can be set to specify a traffic source, or a destination, they cannot specify both on the same rule. This is because AWS always sets the unspecified side (source or destination) as the instance to which the group is applied. Finally, single security groups can be applied to multiple instances, or multiple security groups can be applied to a single instance: AWS is very flexible. This flexibility is one of the unique benefits of AWS, allowing organizations to build bespoke security policies across different functions and even operating systems, mixing and matching them to suit their needs. Adding Network ACLs into the mix To further enhance and enrich its security filtering capabilities AWS also offers a feature called Network Access Control Lists (NACLs). Like security groups, each NACL is a list of rules, but there are two important differences between NACLs and security groups. The first difference is that NACLs are not directly tied to instances, but are tied with the subnet within your AWS virtual private cloud that contains the relevant instance. This means that the rules in a NACL apply to all of the instances within the subnet, in addition to all the rules from the security groups. So a specific instance inherits all the rules from the security groups associated with it, plus the rules associated with a NACL which is optionally associated with a subnet containing that instance. As a result NACLs have a broader reach, and affect more instances than a security group does. The second difference is that NACLs can be written to include an explicit action, so you can write ‘deny’ rules – for example to block traffic from a particular set of IP addresses which are known to be compromised. The ability to write ‘deny’ actions is a crucial part of NACL functionality. It’s all about the order As a consequence, when you have the ability to write both ‘allow’ rules and ‘deny’ rules, the order of the rules now becomes important. If you switch the order of the rules between a ‘deny’ and ‘allow’ rule, then you’re potentially changing your filtering policy quite dramatically. To manage this, AWS uses the concept of a ‘rule number’ within each NACL. By specifying the rule number, you can identify the correct order of the rules for your needs. You can choose which traffic you deny at the outset, and which you then actively allow. As such, with NACLs you can manage security tasks in a way that you cannot do with security groups alone. However, we did point out earlier that an instance inherits security rules from both the security groups, and from the NACLs – so how do these interact? The order by which rules are evaluated is this; For inbound traffic, AWS’s infrastructure first assesses the NACL rules. If traffic gets through the NACL, then all the security groups that are associated with that specific instance are evaluated, and the order in which this happens within and among the security groups is unimportant because they are all ‘allow’ rules. For outbound traffic, this order is reversed: the traffic is first evaluated against the security groups, and then finally against the NACL that is associated with the relevant subnet.

Tags Share this article 8/10/23 Published Problems with firewalls can be quite disastrous to your operations. When firewall rules are not set properly, you might deny all requests, even valid ones, or allow access to unauthorized sources. There needs to be a systematic way to troubleshoot your firewall issues, and you need to have a proper plan. You should consider security standards, hardware/software compatibility, security policy planning , and access level specifications. It is recommended to have an ACL (access control list) to determine who has access to what. Let us give you a brief overview of firewall troubleshooting best practices and steps to follow. Common firewall problems With the many benefits that firewalls bring, they might also pop out some errors and issues now and then. You need to be aware of the common issues, failures, and error codes to properly assess an error condition to ensure the smooth working of your firewalls. Misconfiguration errors A report by Gartner Research says that misconfiguration causes about 95% of all firewall breaches. A simple logical flaw in a firewall rule can open up vulnerabilities, leading to serious security breaches. Before playing with your firewall settings, you must set up proper access control settings and understand the security policy specifications. You must remember that misconfiguration errors in CLI can lead to hefty fines for non-compliance, data breaches , and unnecessary downtimes. All these can cause heavy monetary damages; hence, you should take extra care to configure your firewall rules and settings properly. Here are some common firewall misconfigurations: Allowing ICMP and making the firewall available for ping requests Providing unnecessary services on the firewall Allowing unused TCP/UDP ports The firewall is set to return a ‘deny’ response instead of a ‘drop’ for blocked ports. IP address misconfigurations that can allow TCP pinging of internal hosts from external devices. Trusting DNS and IP addresses that are not properly checked and source verified. Check out AlgoSec’s firewall configuration guide for best practices. Hardware issues Hardware bottlenecks and device misconfigurations can easily lead to firewall failures. Sometimes, running a firewall 24/7 can overload your hardware and lead to a lowered network performance of your entire system. You should look into the performance issues and optimize firewall functionalities or upgrade your hardware accordingly. Software vulnerabilities Any known vulnerability with your firewall software must be dealt with immediately. Hackers can exploit software vulnerabilities easily to gain backdoor entry into your network. So, stay current with all the patches and updates your software vendors provide. Types of firewall issues Most firewall issues can be classified as either connectivity or performance issues. Here are some tools you can use in each of these cases: Connectivity Issues Some loss of access to a network resource or unavailability usually characterizes these issues. You can use network connectivity tools like NetStat to monitor and analyze the inbound TCP/UDP packets. Both these tools have a wide range of sub-commands and tools that help you trace IP network traffic and control the traffic as per your requirements. Firewall Performance Issues As discussed earlier, performance issues can cause a wide range of issues, such as unplanned downtimes and firewall failures, leading to security breaches and slow network performance. Some of the ways you can rectify it include: Load balancing by regulating the outbound network traffic by limiting the internal server errors and streamlining the network traffic. Filtering the incoming network traffic with the help of Standard Access Control List filters. Simplifying firewall rules to reduce the load on the firewall applications. You can remove unused rules and break down complex rules to improve performance. Firewall troubleshooting checklist steps Step 1. Audit your hardware & software Create a firewall troubleshooting checklist to check your firewall rules, software vulnerabilities, hardware settings, and more based on your operating system. This should include all the items you should cover as part of your security policy and network assessment. With Algosec’s policy management , you can ensure that your security policy is complete, comprehensive and does not miss out on anything important. Step 2. Pinpoint the Issue Check what the exact issue is. Generally, a firewall issue can arise from any of the three conditions: Access from external networks/devices to protected resources is not functioning properly Access from the protected network/resources to unprotected resources is not functioning properly. Access to the firewall is not functioning properly. Step 3. Determine the traffic flow Once you have ascertained the exact access issue, you should check whether the issue is raised when traffic is going to the firewall or through the firewall. Once you have narrowed down this issue, you can test the connectivity accordingly and determine the underlying cause. Check for any recent updates and try to roll back if that can solve the issue. Go through your firewall permissions and logs for any error messages or warnings. Review your firewall rules and configurations and adjust them for proper working. Depending upon your firewall installation, you can make a checklist of items. Here is a simple guide you can follow to conduct routine maintenance troubleshooting . Monitor the network, test it out, and repeat the process until you reach a solution. Firewall troubleshooting best practices Here are some proven firewall troubleshooting tips. For more in-depth information, check out our Network Security FAQs page. Monitor and test Regular auditing and testing of your Microsoft firewall can help you catch vulnerabilities early and ensure good performance throughout the year. You can use expert-assisted penetration testing to get a good idea of the efficacy of your firewalls. Also be sure to check out the auditing services from Algosec , especially for your PCI security compliance . Deal with insider threats While a Mac or Windows firewall can help you block external threats to an extent, it can be powerless regarding insider attacks. Make sure you enforce strong security controls to avoid any such conditions. Your security policies must be crafted well to avoid any room for such conditions, and your access level specifications should also be well-defined. Device connections Make sure to pay attention to the other modes of attack that can happen besides a network access attempt. If an infected device such as a USB, router, hard drive, or laptop is directly connected to your system, your network firewall can do little to prevent the attack. So, you should put the necessary device restrictions in your privacy statement and the firewall rules. Review and Improve Update your firewall rules and security policies with regular audits and tests. Here are some more tips you can follow to improve your firewall security: Optimize your firewall ruleset to allow only necessary access Use unique user IP instead of a root ID to launch the firewall services Make use of a protected remote Syslog server and keep it safe from unauthorized access Analyze your firewall logs regularly to identify and detect any suspicious activity. You can use tools like Algosec Firewall Analyzer and expert help to analyze your firewall as well. Disable FTP connections by default Setup strict controls on how and which users can modify firewall configurations. Include both source and destination IP addresses and the ports in your firewall rules. Document all the updates and changes made to your firewall policies and rules. In the case of physical firewall implementations, restrict the physical access as well. Use NAT (network address translation) to map multiple private addresses to a public IP address before transmitting the information online. How does a firewall actually work? A Windows firewall is a network security mechanism that allows you to restrict incoming network traffic to your systems. It can be implemented as a hardware, software, or cloud-based security solution . It acts as a barrier stopping unauthorized network access requests from reaching your internal network and thus minimizing any attempt at hacking or breach of confidential data . Based on the type of implementation and the systems it is protecting, firewalls can be classified into several different types. Some of the common types of firewalls are: Packet filtering – Based on the filter standards, a small amount of incoming data is analyzed and subjected to restriction on distribution across the network. Proxy service – An application layer service that acts as an intermediary between the actual servers to block out unauthorized access requests. Stateful inspection – A dynamic packet filtering mechanism that filters out the network packets. Next-Generation Firewall (NGFW) – A combination of deep packet inspection and application level inspection to block out unauthorized access into the network. Firewalls are essential to network security at all endpoints, whether personal computers or full-scale enterprise data centers. They allow you to set up strong security controls to prevent a wide range of cyberattacks and help you gain valuable data. Firewalls can help you detect suspicious activities and prevent intrusive attacks at the earliest. They can also help you regulate your incoming and outgoing traffic routing, helping you implement zero-trust security policies and stay compliant with security and data standards.

Tags Share this article 10/25/23 Published Firewalls form the first line of defense against intrusive hackers trying to infiltrate internal networks and steal sensitive data. They act as a barrier between networks, clearly defining the perimeters of each. The earliest generation of packet-filter firewalls were rudimentary compared to today’s next-generation firewalls, but cybercrime threats were also less sophisticated. Since then, cybersecurity vendors have added new security features to firewalls in response to emerging cyber threats. Today, organizations can choose between many different types of firewalls designed for a wide variety of purposes. Optimizing your organization’s firewall implementation requires understanding the differences between firewalls and the network layers they protect. How Do Firewalls Work? Firewalls protect networks by inspecting data packets as they travel from one place to another. These packets are organized according to the transmission control protocol/internet protocol (TCP/IP), which provides a standard way to organize data in transit. This protocol is a concise version of the more general OSI model commonly used to describe computer networks. These frameworks allow firewalls to interpret incoming traffic according to strictly defined standards. Security experts use these standards to create rules that tell firewalls what to do when they detect unusual traffic. The OSI model has seven layers: Application Presentation Session Transport Network Data link Physical Most of the traffic that reaches your firewall will use one of the three major Transport layer protocols in this model, TCP, UDP, or ICMP. Many security experts focus on TCP rules because this protocol uses a three-step TCP handshake to provide a reliable two-way connection. The earliest firewalls only operated on the Network Layer, which provides information about source and destination IP addresses, protocols, and port numbers. Later firewalls added Transport Layer and Application Layer functionality. The latest next-generation firewalls go even further, allowing organizations to enforce identity-based policies directly from the firewall. Related Read : Host-Based vs. Network-Based Firewalls 1. Traditional Firewalls Packet Filtering Firewalls Packet-filtering firewalls only examine Network Layer data, filtering out traffic according to the network address, the protocol used, or source and destination port data. Because they do not inspect the connection state of individual data packets, they are also called stateless firewalls. These firewalls are simple and they don’t support advanced inspection features. However, they offer low latency and high throughput, making them ideal for certain low-cost inline security applications. Stateful Inspection Firewalls When stateful firewalls inspect data packets, they capture details about active sessions and connection states. Recording this data provides visibility into the Transport layer and allows the firewall to make more complex decisions. For example, a stateful firewall can mitigate a denial-of-service attack by comparing a spike in incoming traffic against rules for making new connections – stateless firewalls don’t have a historical record of connections to look up. These firewalls are also called dynamic packet-filtering firewalls. They are generally more secure than stateless firewalls but may introduce latency because it takes time to inspect every data packet traveling through the network. Circuit-Level Gateways Circuit-level gateways act as a proxy between two devices attempting to connect with one another. These firewalls work on the Session layer of the OSI model, performing the TCP handshake on behalf of a protected internal server. This effectively hides valuable information about the internal host, preventing attackers from conducting reconnaissance into potential targets. Instead of inspecting individual data packets, these firewalls translate internal IP addresses to registered Network Address Translation (NAT) addresses. NAT rules allow organizations to protect servers and endpoints by preventing their internal IP address from being public knowledge. 2. Next-Generation Firewalls (NGFWs) Traditional firewalls only address threats from a few layers in the OSI model. Advanced threats can bypass these Network and Transport Layer protections to attack web applications directly. To address these threats, firewalls must be able to analyze individual users, devices, and data assets as they travel through complex enterprise networks. Next-generation firewalls achieve this by looking beyond the port and protocol data of individual packets and sessions. This grants visibility into sophisticated threats that simpler firewalls would overlook. For example, a traditional firewall may block traffic from an IP address known for conducting denial-of-service attacks. Hackers can bypass this by continuously changing IP addresses to confuse and overload the firewall, which may allow routing malicious traffic to vulnerable assets. A next-generation firewall may notice that all this incoming traffic carries the same malicious content. It may act as a TCP proxy and limit the number of new connections made per second. When illegitimate connections fail the TCP handshake, it can simply drop them without causing the organization’s internal systems to overload. This is just one example of what next-gen firewalls are capable of. Most modern firewall products combine a wide variety of technologies to provide comprehensive perimeter security against comprehensive cyber attacks. How do NGFWs Enhance Network Security? Deep Packet Inspection (DPI) : NGFWs go beyond basic packet filtering by inspecting the content of data packets. They analyze the actual data payload and not just header information. This allows them to identify and block threats within the packet content, such as malware, viruses, and suspicious patterns. Application-Level Control : NGFWs can identify and control applications and services running on the network. This enables administrators to define and enforce policies based on specific applications, rather than just port numbers. For example, you can allow or deny access to social media sites or file-sharing applications. Intrusion Prevention Systems (IPS) : NGFWs often incorporate intrusion prevention capabilities. They can detect and prevent known and emerging cyber threats by comparing network traffic patterns against a database of known attack signatures. This proactive approach helps protect against various cyberattacks. Advanced Threat Detection: NGFWs use behavioral analysis and heuristics to detect and block unknown or zero-day threats. By monitoring network traffic for anomalies, they can identify suspicious behavior and take action to mitigate potential threats. U ser and Device Identification : NGFWs can associate network traffic with specific users or devices, even in complex network environments. This user/device awareness allows for more granular security policies and helps in tracking and responding to security incidents effectively. Integration with Security Ecosystem : NGFWs often integrate with other security solutions, such as antivirus software, intrusion detection systems (IDS), and security information and event management (SIEM) systems. This collaborative approach provides a multi-layered defense strategy . Security Automation : NGFWs can automate threat response and mitigation. For example, they can isolate compromised devices from the network or initiate other predefined actions to contain threats swiftly. In a multi-layered security environment, these firewalls often enforce the policies established by security orchestration, automation, and response (SOAR) platforms. Content Filtering : NGFWs can filter web content, providing URL filtering and content categorization. This helps organizations enforce internet usage policies and block access to potentially harmful or inappropriate websites. Some NGFWs can even detect outgoing user credentials (like an employee’s Microsoft account password) and prevent that content from leaving the network. VPN and Secure Remote Access : NGFWs often include VPN capabilities to secure remote connections. This is crucial for ensuring the security of remote workers and branch offices. Advanced firewalls may also be able to identify malicious patterns in external VPN traffic, protecting organizations from threat actors hiding behind encrypted VPN providers. Cloud-Based Threat Intelligence : Many NGFWs leverage cloud-based threat intelligence services to stay updated with the latest threat information. This real-time threat intelligence helps NGFWs identify and block emerging threats more effectively. Scalability and Performance : NGFWs are designed to handle the increasing volume of network traffic in modern networks. They offer improved performance and scalability, ensuring that security does not compromise network speed. Logging and Reporting : NGFWs generate detailed logs and reports of network activity. These logs are valuable for auditing, compliance, and forensic analysis, helping organizations understand and respond to security incidents. 3. Proxy Firewalls Proxy firewalls are also called application-level gateways or gateway firewalls. They define which applications a network can support, increasing security but demanding continuous attention to maintain network functionality and efficiency. Proxy firewalls provide a single point of access allowing organizations to assess the threat posed by the applications they use. It conducts deep packet inspection and uses proxy-based architecture to mitigate the risk of Application Layer attacks. Many organizations use proxy servers to segment the parts of their network most likely to come under attack. Proxy firewalls can monitor the core internet protocols these servers use against every application they support. The proxy firewall centralizes application activity into a single server and provides visibility into each data packet processed. This allows the organization to maintain a high level of security on servers that make tempting cyberattack targets. However, these servers won’t be able to support new applications without additional firewall configuration. These types of firewalls work well in highly segmented networks that allow organizations to restrict access to sensitive data without impacting usability and production. 4. Hardware Firewalls Hardware firewalls are physical devices that secure the flow of traffic between devices in a network. Before cloud computing became prevalent, most firewalls were physical hardware devices. Now, organizations can choose to secure on-premises network infrastructure using hardware firewalls that manage the connections between routers, switches, and individual devices. While the initial cost of acquiring and configuring a hardware firewall can be high, the ongoing overhead costs are smaller than what software firewall vendors charge (often an annual license fee). This pricing structure makes it difficult for growing organizations to rely entirely on hardware devices. There is always a chance that you end up paying for equipment you don’t end up using at full capacity. Hardware firewalls offer a few advantages over software firewalls: They avoid using network resources that could otherwise go to value-generating tasks. They may end up costing less over time than a continuously renewed software firewall subscription fee. Centralized logging and monitoring can make hardware firewalls easier to manage than complex software-based deployments. 5. Software Firewalls Many firewall vendors provide virtualized versions of their products as software. They typically charge an annual licensing fee for their firewall-as-a-service product, which runs on any suitably provisioned server or device. Some software firewall configurations require the software to be installed on every computer in the network, which can increase the complexity of deployment and maintenance over time. If firewall administrators forget to update a single device, it may become a security vulnerability. At the same time, these firewalls don’t have their own operating systems or dedicated system resources available. They must draw computing power and memory from the devices they are installed on. This leaves less power available for mission-critical tasks. However, software firewalls carry a few advantages compared to hardware firewalls: The initial subscription-based cost is much lower, and many vendors offer a price structure that ensures you don’t pay for resources you don’t use. Software firewalls do not take up any physical space, making them ideal for smaller organizations. The process of deploying software firewalls often only takes a few clicks. With hardware firewalls, the process can involve complex wiring and time-consuming testing. Advanced Threats and Firewall Solutions Most firewalls are well-equipped to block simple threats, but advanced threats can still cause problems. There are many different types of advanced threats designed to bypass standard firewall policies. Advanced Persistent Threats (APTs) often compromise high-level user accounts and slowly spread throughout the network using lateral movement. They may move slowly, gathering information and account credentials over weeks or months before exfiltrating the data undetected. By moving slowly, these threats avoid triggering firewall rules. Credential-based attacks bypass simple firewall rules by using genuine user credentials to carry out attacks. Since most firewall policies trust authenticated users, attackers can easily bypass rules by stealing user account credentials. Simple firewalls can’t distinguish between normal traffic and malicious traffic by an authenticated, signed-in user. Malicious insiders can be incredibly difficult to detect. These are genuine, authenticated users who have decided to act against the organization’s interest. They may already know how the firewall system works, or have privileged access to firewall configurations and policies. Combination attacks may target multiple security layers with separate, independent attacks. For example, your cloud-based firewalls may face a Distributed Denial of Service (DDoS) attack while a malicious insider exfiltrates information from the cloud. These tactics allow hackers to coordinate attacks and cover their tracks. Only next-generation firewalls have security features that can address these types of attack. Anti-data exfiltration tools may prevent users from sending their login credentials to unsecured destinations, or prevent large-scale data exfiltration altogether. Identity-based policies may block authenticated users from accessing assets they do not routinely use. Firewall Configuration and Security Policies The success of any firewall implementation is determined by the quality of its security rules. These rules decide which types of traffic the firewall will allow to pass, and what traffic it will block. In a modern network environment, this is done using four basic types of firewall rules: Access Control Lists (ACLs). These identify the users who have permission to access a certain resource or asset. They may also dictate which operations are allowed on that resource or asset. Network Address Translation (NAT) rules. These rules protect internal devices by hiding their original IP address from the public Internet. This makes it harder for hackers to gain unauthorized access to system resources because they can’t easily target individual devices from outside the network. Stateful packet filtering . This is the process of inspecting data packets in each connection and determining what to do with data flows that do not appear genuine. Stateful firewalls keep track of existing connections, allowing them to verify the authentication of incoming data that claims to be part of an already established connection. Application-level gateways. These firewall rules provide application-level protection, preventing hackers from disguising malicious traffic as data from (or for) an application. To perform this kind of inspection, the firewall must know what normal traffic looks like for each application on the network, and be able to match incoming traffic with those applications. Network Performance and Firewalls Firewalls can impact network performance and introduce latency into networks. Optimizing network performance with firewalls is a major challenge in any firewall implementation project. Firewall experts use a few different approaches to reduce latency and maintain fast, reliable network performance: Installing hardware firewalls on high-volume routes helps, since separate physical devices won’t draw computing resources away from other network devices. Using software firewalls in low-volume situations where flexibility is important. Sometimes, being able to quickly configure firewall rules to adapt to changing business conditions can make a major difference in overall network performance. Configuring servers to efficiently block unwanted traffic is a continuous process. Server administrators should avoid overloading firewalls with denied outbound requests that strain firewalls at the network perimeter. Firewall administrators should try to distribute unwanted traffic across multiple firewalls and routers instead of allowing it to concentrate on one or two devices. They should also try reducing the complexity of the firewall rule base and minimize overlapping rules.

Cloud Security A Guide to Upskilling Your Cloud Architects & Security Teams in 2023 Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/2/23 Published Cloud threats are at an all-time high. But not only that, hackers are becoming more sophisticated with cutting-edge tools and new ways to attack your systems. Cloud service providers can only do so much. So, most of the responsibility for securing your data and applications will still fall on you. This makes it critical to equip your organization’s cloud architects and security teams with the necessary skills that help them stay ahead of the evolving threat landscape. Although the core qualities of a cloud architect remain the same, upskilling requires them to learn emerging skills in strategy, leadership, operational, and technical areas. Doing this makes your cloud architects and security teams well-rounded to solve complex cloud issues and ensure the successful design of cloud security architecture. Here, we’ll outline the top skills for cloud architects. This can be a guide for upskilling your current security team and hiring new cloud security architects. But besides the emerging skills, what are the core responsibilities of a cloud security architect? Responsibilities of Cloud Security Architects A cloud security architect builds, designs, and deploys security systems and controls for cloud-based computing services and data storage systems. Their responsibilities will likely depend on your organization’s cloud security strategy. Here are some of them: 1. Plan and Manage the Organization’s Cloud Security Architecture and Strategy: Security architects must work with other security team members and employees to ensure the security architecture aligns with your organization’s strategic goals. 2. Select Appropriate Security Tools and Controls: Cloud security architects must understand the capabilities and limitations of cloud security tools and controls and contribute when selecting the appropriate ones. This includes existing enterprise tools with extensibility to cloud environments, cloud-native security controls, and third-party services. They are responsible for designing new security protocols whenever needed and testing them to ensure they work as expected. 3. Determine Areas of Deployments for Security Controls: After selecting the right tools, controls, and measures, architects must also determine where they should be deployed within the cloud security architecture. 4. Participating in Forensic Investigations: Security architects may also participate in digital forensics and incident response during and after events. These investigations can help determine how future incidents can be prevented. 5. Define Design Principles that Govern Cloud Security Decisions: Cloud security architects will outline design principles that will be used to make choices on the security tools and controls to be deployed, where, and from which sources or vendors. 6. Educating employees on data security best practices: Untrained employees can undo the efforts of cloud security architects. So, security architects must educate technical and non-technical employees on the importance of data security. This includes best practices for creating strong passwords, identifying social engineering attacks, and protecting sensitive information. Best Practices for Prioritizing Cloud Security Architecture Skills Like many other organizations, there’s a good chance your company has moved (or is in the process of moving) all or part of its resources to the cloud. This could either be a cloud-first or cloud-only strategy. As such, they must implement strong security measures that protect the enterprise from emerging threats and intrusions. Cloud security architecture is only one of many aspects of cloud security disciplines. And professionals specializing in this field must advance their skillset to make proper selections for security technologies, procedures, and the entire architecture. However, your cloud security architects cannot learn everything. So, you must prioritize and determine the skills that will help them become better architects and deliver effective security architectures for your organization. To do this, you may want to consider the demand and usage of the skill in your organization. Will upskilling them with these skills solve any key challenge or pain point in your organization? You can achieve this by identifying the native security tools key to business requirements, compliance adherence, and how cloud risks can be managed effectively. Additionally, you should consider the relevance of the skill to the current cloud security ecosystem. Can they apply this skill immediately? Does it make them better cloud security architects? Lastly, different cloud deployment (e.g., a public, private, edge, and distributed cloud) or cloud service models (e.g., Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS)) bring unique challenges that demand different skillsets. So, you must identify the necessary skills peculiar to each proposed project. Once you have all these figured out, here are some must-have skillsets for cloud security architects. Critical Skills for Cloud Security Architect Cloud security architects need several common skills, like knowledge of programming languages (.NET, PHP, Python, Java, Ruby, etc.), network integration with cloud services, and operating systems (Windows, macOS, and Linux). However, due to the evolving nature of cloud threats, more skills are required. Training your security teams and architects can have more advantages than onboarding new recruits. This is because existing teams are already familiar with your organization’s processes, culture, and values. However, whether you’re hiring new cloud security architects or upskilling your current workforce, here are the most valuable skills to look out for or learn. 1. Experience in cloud deployment models (IaaS, PaaS, and SaaS) It’s important to have cloud architects and security teams that integrate various security components in different cloud deployments for optimal results. They must understand the appropriate security capabilities and patterns for each deployment. This includes adapting to unique security requirements during deployment, combining cloud-native and third-party tools, and understanding the shared responsibility model between the CSP and your organization. 2. Knowledge of cloud security frameworks and standards Cloud security frameworks, standards, and methodologies provide a structured approach to security activities. Interpreting and applying these frameworks and standards is a critical skill for security architects. Some cloud security frameworks and standards include ISO 27001, ISAE 3402, CSA STAR, and CIS benchmarks. Familiarity with regional or industry-specific requirements like HIPAA, CCPA, and PCI DSS can ensure compliance with regulatory requirements. Best practices like the AWS Well-Architected Framework, Microsoft Cloud Security Benchmark, and Microsoft Cybersecurity Reference Architectures are also necessary skills. 3. Understanding of Native Cloud Security Tools and Where to Apply Them Although most CSPs have native tools that streamline your cloud security policies, understanding which tools your organization needs and where is a must-have skill. There are a few reasons why; it’s cost-effective, integrates seamlessly with the respective cloud platform, enhances management and configuration, and aligns with the CSP’s security updates. Still, not all native tools are necessary for your cloud architecture. As native security tools evolve, cloud architects must constantly be ahead by understanding their capabilities. 4. Knowledge of Cloud Identity and Access Management (IAM) Patterns IAM is essential for managing user access and permissions within the cloud environment. Familiarity with IAM patterns ensures proper security controls are in place. Note that popular cloud service providers, like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, may have different processes for implementing IAM. However, the key principles of IAM policies remain. So, your cloud architects must understand how to define appropriate IAM measures for access controls, user identities, authentication techniques like multi-factor authentication (MFA) or single sign-on (SSO), and limiting data exfiltration risks in SaaS apps. 5. Proficiency with Cloud-Native Application Protection Platforms CNAPP is a cloud-native security model that combines the capabilities of Cloud Security Posture Management (CSPM), Cloud Workload Protection Platform (CWPP), and Cloud Service Network Security (CSNS) into a single platform. Cloud solutions like this simplify monitoring, detecting, and mitigating cloud security threats and vulnerabilities. As the nature of threats advances, using CNAPPs like Prevasio can provide comprehensive visibility and security of your cloud assets like Virtual Machines, containers, object storage, etc. CNAPPs enable cloud security architects to enhance risk prioritization by providing valuable insights into Kubernetes stack security configuration through improved assessments. 6. Aligning Your Cloud Security Architecture with Business Requirements It’s necessary to align your cloud security architecture with your business’s strategic goals. Every organization has unique requirements, and your risk tolerance levels will differ. When security architects are equipped to understand how to bridge security architecture and business requirements, they can ensure all security measures and control are calibrated to mitigate risks. This allows you to prioritize security controls, ensures optimal resource allocation, and improves compliance with industry-specific regulatory requirements. 7. Experience with Legacy Information Systems Although cloud adoption is increasing, many organizations have still not moved all their assets to the cloud. At some point, some of your on-premises legacy systems may need to be hosted in a cloud environment. However, legacy information systems’ architecture, technologies, and security mechanisms differ from modern cloud environments. This makes it important to have cloud security architects with experience working with legacy information systems. Their knowledge will help your organization solve any integration challenges when moving to the cloud. It will also help you avoid security vulnerabilities associated with legacy systems and ensure continuity and interoperability (such as data synchronization and maintaining data integrity) between these systems and cloud technologies. 8. Proficiency with Databases, Networks, and Database Management Systems (DBMS) Cloud security architects must also understand how databases and database management systems (DBMS) work. This knowledge allows them to design and implement the right measures that protect data stored within the cloud infrastructure. Proficiency with databases can also help them implement appropriate access controls and authentication measures for securing databases in the cloud. For example, they can enforce role-based access controls (RBAC) within the database environment. 9. Solid Understanding of Cloud DevOps DevOps is increasingly becoming more adopted than traditional software development processes. So, it’s necessary to help your cloud security architects embrace and support DevOps practices. This involves developing skills related to application and infrastructure delivery. They should familiarize themselves with tools that enable integration and automation throughout the software delivery lifecycle. Additionally, architects should understand agile development processes and actively work to ensure that security is seamlessly incorporated into the delivery process. Other crucial skills to consider include cloud risk management for enterprises, understanding business architecture, and approaches to container service security. Conclusion By upskilling your cloud security architects, you’re investing in their personal development and equipping them with skills to navigate the rapidly evolving cloud threat landscape. It allows them to stay ahead of emerging threats, align cloud security practices with your business requirements, and optimize cloud-native security tools.

Tags Share this article 1/2/24 Published Jeremiah Cornelius, Technical Lead for Alliances and Partners at AlgoSec, discusses how Cisco Nexus Dashboard Orchestrator (NDO) users can achieve policy-driven application-centric security management with AlgoSec. Leading Edge of the Data Center with AlgoSec and Cisco NDO AlgoSec ASMS A32.6 is our latest release to feature a major technology integration, built upon our well-established collaboration with Cisco — bringing this partnership to the front of the Cisco innovation cycle with support for Nexus Dashboard Orchestrator (NDO) . NDO allows Cisco ACI – and legacy-style Data Center Network Management – to operate at scale in a global context, across data center and cloud regions. The AlgoSec solution with NDO brings the power of our intelligent automation and software-defined security features for ACI, including planning, change management, and microsegmentation, to this global scope. I urge you to see what AlgoSec delivers for ACI with multiple use cases, enabling application-mode operation and microsegmentation, and delivering integrated security operations workflows. AlgoSec now brings support for Shadow EPG and Inter-Site Contracts with NDO, to our existing ACI strength. Let’s Change the World by Intent I had my first encounter with Cisco Application Centric Infrastructure in 2014 at a Symantec Vision conference. The original Senior Product Manager and Technical Marketing lead were hosting a discussion about the new results from their recent Insieme acquisition and were eager to onboard new partners with security cases and added operations value. At the time I was promoting the security ecosystem of a different platform vendor, and I have to admit that I didn’t fully understand the tremendous changes that ACI was bringing to security for enterprise connectivity. It’s hard to believe that it’s now seven years since then and that Cisco ACI has mainstreamed software-defined networking — changing the way that network teams had grown used to running their networks and devices since at least the mid-’90s. Since that 2014 introduction, Cisco’s ACI changed the landscape of data center networking by introducing an intent-based approach, over earlier configuration-centric architecture models. This opened the way for accelerated movement by enterprise data centers to meet their requirements for internal cloud deployments, new DevOps and serverless application models, and the extension of these to public clouds for hybrid operation – all within a single networking technology that uses familiar switching elements. Two new, software-defined artifacts make this possible in ACI: End-Point Groups (EPG) and Contracts – individual rules that define characteristics and behavior for an allowed network connection. ACI Is Great, NDO Is Global That’s really where NDO comes into the picture. By now, we have an ACI-driven data center networking infrastructure, with management redundancy for the availability of applications and preserving their intent characteristics. Through the use of an infrastructure built on EPGs and contracts, we can reach from the mobile and desktop to the datacenter and the cloud. This means our next barrier is the sharing of intent-based objects and management operations, beyond the confines of a single data center. We want to do this without clustering types, that depend on the availability risk of individual controllers, and hit other limits for availability and oversight. Instead of labor-intensive and error-prone duplication of data center networks and security in different regions, and for different zones of cloud operation, NDO introduces “stretched” shadow EPGs, and inter-site contracts, for application-centric and intent-based, secure traffic which is agnostic to global topologies – wherever your users and applications need to be. NDO Deployment Topology – Image: Cisco Getting NDO Together with AlgoSec: Policy-Driven, App-Centric Security Management  Having added NDO capability to the formidable shared platform of AlgoSec and Cisco ACI, regional-wide and global policy operations can be executed in confidence with intelligent automation. AlgoSec makes it possible to plan for operations of the Cisco NDO scope of connected fabrics in application-centric mode, unlocking the ACI super-powers for micro-segmentation. This enables a shared model between networking and security teams for zero-trust and defense-in-depth, with accelerated, global-scope, secure application changes at the speed of business demand — within minutes, rather than days or weeks. Change management : For security policy change management this means that workloads may be securely re-located from on-premises to public cloud, under a single and uniform network model and change-management framework — ensuring consistency across multiple clouds and hybrid environments. Visibility : With an NDO-enabled ACI networking infrastructure and AlgoSec’s ASMS, all connectivity can be visualized at multiple levels of detail, across an entire multi-vendor, multi-cloud network. This means that individual security risks can be directly correlated to the assets that are impacted, and a full understanding of the impact by security controls on an application’s availability. Risk and Compliance : It’s possible across all the NDO connected fabrics to identify risk on-premises and through the connected ACI cloud networks, including additional cloud-provider security controls. The AlgoSec solution makes this a self-documenting system for NDO, with detailed reporting and an audit trail of network security changes, related to original business and application requests. This means that you can generate automated compliance reports, supporting a wide range of global regulations, and your own, self-tailored policies. The Road Ahead Cisco NDO is a major technology and AlgoSec is in the early days with our feature introduction, nonetheless, we are delighted and enthusiastic about our early adoption customers. Based on early reports with our Cisco partners, needs will arise for more automation, which would include the “zero-touch” push for policy changes – committing Shadow EPG and Inter-site Contract changes to the orchestrator, as we currently do for ACI APIC. Feedback will also shape a need for automation playbooks and workflows that are most useful in the NDO context, and that we can realize with a full committable policy by the ASMS Horizon Security Analyzer. Contact Us! I encourage anyone interested in NDO and enhancing their operational maturity in aligned network and security operation, to talk to us about our joint solution. We work together with Cisco teams and resellers and will be glad to share more. Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 4/27/23 Published Ensuring your cloud environment is secure and compliant with industry practices is critical. Cloud security best practices will help you protect your organization’s data and applications. In the process, reduce the risks of security compromise. This post will walk you through the best practices for cloud security. We’ll also share the top cloud security risks and how to mitigate them. The top 5 security risks to cloud computing right now Social engineering. Social engineering attackers use psychological deception to manipulate users into providing sensitive information. These deception tactics may include phishing, pretexting, or baiting. Account compromise. An account compromise occurs when an attacker obtains unauthorized entry to it. A hacker can access your account when you use weak passwords or steal your credentials. They may introduce malware or steal your files once they access your account. Shadow IT. This security risk occurs when your employee uses hardware or software that the IT department does not approve. It may result in compliance problems, data loss, and a higher risk of cyberattacks. Insider activity (unintentional or malicious) . Insider activity occurs when approved users damage your company’s data or network. These users can either do it purposefully or accidentally on-premises. For example, you may disclose private information unintentionally or steal data on purpose. Insecure APIs . APIs make communication easier for cloud services and other software applications. Insecure APIs can allow unauthorized access to sensitive data. This could, in turn, lead to malicious attacks, such as data theft. The attackers could also do illegal data alteration from data centers. 16 best practices for cloud security Establish zero-trust architecture Use role-based access control Monitor suspicious activity Monitor privileged users Encrypt data in motion and at rest Investigate shadow IT applications Protect Endpoints Educate employees about threats Create and enforce a password policy Implement multi-factor authentication Understand the shared responsibility model m Audit IaaS configurations Review SLAs and contracts. Maintaining logs and monitoring Use vulnerability and penetration testing Consider intrusion detection and prevention One of the most critical areas of cloud security is identity and access management. We will also discuss sensitive data protection, social engineering attacks, cloud deployments, and incident response. Best practices for managing access. Access control is an integral part of cloud network security. It restricts who can access cloud services, what they can do with the data, and when. Here are some of the best practices for managing access: Establish zero-trust architecture Zero-trust architecture is a security concept that treats all traffic in or out of your network as untrusted. It considers that every request may be malicious. So you must verify your request, even if it originates from within the network. You can apply zero-trust architecture by dividing the system into smaller, more secure cloud zones. And then enforce strict access policies for each zone. This best practice will help you understand who accesses your cloud services. You’ll also know what they do with your data resources. Use role-based access control Role-based access control allows you to assign users different access rights based on their roles. This method lessens the chances of giving people unauthorized access privileges. It also simplifies the administration of access rights. RBAC also simplifies upholding the tenet of least privilege. It restricts user permission to only the resources they need to do their jobs. This way, users don’t have excessive access that attackers could exploit. Monitor suspicious activity Monitoring suspicious behavior involves tracking and analyzing user activity in a cloud environment. It helps identify odd activities, such as user accounts accessing unauthorized data. You should also set up alerts for suspicious activities. Adopting this security strategy will help you spot security incidents early and react quickly. This best practice will help you improve your cloud functionality. It will also protect your sensitive data from unwanted access or malicious activities. Monitor privileged users Privileged users have high-level access rights and permissions. They can create, delete and modify data in the cloud environment. You should consider these users as a huge cybersecurity risk. Your privileged users can cause significant harm if they get compromised. Closely watch these users’ access rights and activity. By doing so, you’ll easily spot misuse of permissions and avert data breaches. You can also use privileged access management systems (PAS) to control access to privileged accounts. Enforcing security certifications also helps privileged users avoid making grievous mistakes. They’ll learn the actions that can pose a cybersecurity threat to their organization. Best practices for protecting sensitive data Safeguarding sensitive data is critical for organizational security. You need security measures to secure the cloud data you store, process and transfer. Encrypt data in motion and at rest Encrypting cloud data in transit and at rest is critical to data security. When you encrypt your data, it transforms into an unreadable format. So only authorized users with a decryption key can make it readable again. This way, cybercriminals will not access your sensitive data. To protect your cloud data in transit, use encryption protocols like TSL and SSL. And for cloud data at rest, use powerful encryption algorithms like AES and RSA. Investigate shadow IT applications Shadow IT apps can present a security risk as they often lack the same level of security as sanctioned apps. Investigating Shadow IT apps helps ensure they do not pose any security risks. For example, some staff may use cloud storage services that are insecure. If you realize that, you can propose sanctioned cloud storage software as a service apps like Dropbox and Google Drive. You can also use software asset management tools to monitor the apps in your environment. A good example is the SaaS solution known as Flexera software asset management. Protect Endpoints Endpoints are essential in maintaining a secure cloud infrastructure. They can cause a huge security issue if you don’t monitor them closely. Computers and smartphones are often the weakest points in your security strategy. So, hackers target them the most because of their high vulnerability. Cybercriminals may then introduce ransomware into your cloud through these endpoints. To protect your endpoints, employ security solutions like antimalware and antivirus software. You could also use endpoint detection and response systems (EDRs) to protect your endpoints from threats. EDRs use firewalls as a barrier between the endpoints and the outside world. These firewalls will monitor and block suspicious traffic from accessing your endpoints in real time. Best practices for preventing social engineering attacks Use these best practices to protect your organization from social engineering attacks: Educate employees about threats Educating workers on the techniques that attackers use helps create a security-minded culture. Your employees will be able to detect malicious attempts and respond appropriately. You can train them on deception techniques such as phishing, baiting, and pretexting. Also, make it your policy that every employee takes security certifications on a regular basis. You can tell them to report anything they suspect to be a security threat to the IT department. They’ll be assured that your security team can handle any security issues they may face. Create and enforce a password policy A password policy helps ensure your employees’ passwords are secure and regularly updated. It also sets up rules everyone must follow when creating and using passwords. Some rules in your password policy can be: Setting a minimum password length when creating passwords. No reusing of passwords. The frequency with which to change passwords. The characteristics of a strong password. A strong password policy safeguards your cloud-based operations from social engineering assaults. Implement multi-factor authentication Multi-factor authentication adds an extra layer of security to protect the users’ accounts. This security tool requires users to provide extra credentials to access their accounts. For example, you may need a one-time code sent via text or an authentication app to log into your account. This extra layer of protection reduces the chances of unauthorized access to accounts. Hackers will find it hard to steal sensitive data even if they have your password. In the process, you’ll prevent data loss from your cloud platform. Leverage the multifactor authentication options that public cloud providers usually offer. For example, Amazon Web Services (AWS) offers multifactor authentication for its users. Best practices for securing your cloud deployments. Your cloud deployments are as secure or insecure as the processes you use to manage them. This is especially true for multi-cloud environments where the risks are even higher. Use these best practices to secure your cloud deployments: Understand the shared responsibility model The shared responsibility model is a concept that drives cloud best practices. It states that cloud providers and customers are responsible for different security aspects. Cloud service providers are responsible for the underlying infrastructure and its security. On the other hand, customers are responsible for their apps, data, and settings in the cloud. Familiarize yourself with the Amazon Web Services (AWS) or Microsoft Azure guides. This ensures you’re aware of the roles of your cloud service provider. Understanding the shared security model will help safeguard your cloud platform. Audit IaaS configurations Cloud deployments of workloads are prone to misconfigurations and vulnerabilities. So it’s important to regularly audit your Infrastructure as a Service (IaaS) configurations. Check that all IaaS configurations align with industry best practices and security standards. Regularly check for weaknesses, misconfigurations, and other security vulnerabilities. This best practice is critical if you are using a multi-cloud environment. The level of complexity arises, which in turn increases the risk of attacks. Auditing IaaS configurations will secure your valuable cloud data and assets from potential cyberattacks. Review SLAs and contracts. Reviewing SLAs and contracts is a crucial best practice for safeguarding cloud installations. It ensures that all parties know their respective security roles. You should review SLAs to ensure cloud deployments meet your needs while complying with industry standards. Examining the contracts also helps you identify potential risks, like data breaches. This way, you prepare elaborate incident responses. Best practices for incident response Cloud environments are dynamic and can quickly become vulnerable to cyberattacks. So your security/DevOps team should design incident response plans to resolve potential security incidents. Here are some of the best practices for incident response: Maintaining logs and monitoring Maintaining logs and monitoring helps you spot potential cybersecurity threats in real time. In the process, enable your security to respond quickly using the right security controls. Maintaining logs involves tracking all the activities that occur in a system. In your cloud environment, it can record login attempts, errors, and other network activity. Monitoring your network activity lets you easily spot a breach’s origin and damage severity. Use vulnerability and penetration testing Vulnerability assessment and penetration testing can help you identify weaknesses in your cloud. These tests mimic attacks on a company’s cloud infrastructure to find vulnerabilities that cybercriminals may exploit. Through automation, these security controls can assist in locating security flaws, incorrect setups, and other weaknesses early. You can then measure the adequacy of your security policies to address these flaws. This will let you know if your cloud security can withstand real-life incidents. Vulnerability and penetration testing is a crucial best practice for handling incidents in cloud security. It may dramatically improve your organization’s overall security posture. Consider intrusion detection and prevention Intrusion detection and prevention systems (IDPS) are essential to a robust security strategy. Intrusion detection involves identifying potential cybersecurity threats in your network. Through automation, intrusion detection tools monitor your network traffic in real-time for suspicious activity. Intrusion prevention systems (IPS) go further by actively blocking malicious activity. These security tools can help prevent any harm by malware attacks in your cloud environment. The bottom line on cloud security. You must enforce best practices to keep your cloud environment secure. This way, you’ll lower the risks of cyberattacks which can have catastrophic results. A CSPM tool like Prevasio can help you enforce your cloud security best practices in many ways. It can provide visibility into your cloud environment and help you identify misconfigurations. Prevasio can also allow you to set up automated security policies to apply across the entire cloud environment. This ensures your cloud users abide by all your best practices for cloud security.

Cloud Security Best Practices for Docker Containers’ Security Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 7/27/20 Published Containers aren’t VMs. They’re a great lightweight deployment solution, but they’re only as secure as you make them. You need to keep them in processes with limited capabilities, granting them only what they need. A process that has unlimited power, or one that can escalate its way there, can do unlimited damage if it’s compromised. Sound security practices will reduce the consequences of security incidents. Don’t grant absolute power It may seem too obvious to say, but never run a container as root. If your application must have quasi-root privileges, you can place the account within a user namespace , making it the root for the container but not the host machine. Also, don’t use the –privileged flag unless there’s a compelling reason. It’s one thing if the container does direct I/O on an embedded system, but normal application software should never need it. Containers should run under an owner that has access to its own resources but not to other accounts. If a third-party image requires the –privileged flag without an obvious reason, there’s a good chance it’s badly designed if not malicious. Avoid running a Docker socket in a container. It gives the process access to the Docker daemon, which is a useful but dangerous power. It includes the ability to control other containers, images, and volumes. If this kind of capability is necessary, it’s better to go through a proper API. Grant privileges as needed Applying the principle of least privilege minimizes container risks. A good approach is to drop all capabilities using –cap-drop=all and then enabling the ones that are needed with –cap-add . Each capability expands the attack surface between the container and its environment. Many workloads don’t need any added capabilities at all. The no-new-privileges flag under security-opt is another way to protect against privilege escalation. Dropping all capabilities does the same thing, so you don’t need both. Limiting the system resources which a container guards not only against runaway processes but against container-based DoS attacks. Beware of dubious images When possible, use official Docker images. They’re well documented and tested for security issues, and images are available for many common situations. Be wary of backdoored images . Someone put 17 malicious container images on Docker Hub, and they were downloaded over 5 million times before being removed. Some of them engaged in cryptomining on their hosts, wasting many processor cycles while generating $90,000 in Monero for the images’ creator. Other images may leak confidential data to an outside server. Many containerized environments are undoubtedly still running them. You should treat Docker images with the same caution you’d treat code libraries, CMS plugins, and other supporting software, Use only code that comes from a trustworthy source and is delivered through a reputable channel. Other considerations It should go without saying, but you need to rebuild your images regularly. The libraries and dependencies that they use get security patches from time to time, and you need to make sure your containers have them applied. On Linux, you can gain additional protection from security profiles such as secomp and AppArmor . These modules, used with the security-opt settings, let you set policies that will be automatically enforced. Container security presents its distinctive challenges. Experience with traditional application security helps in many ways, but Docker requires an additional set of practices. Still, the basics apply as much as ever. Start with trusted code. Don’t give it the power to do more than it needs to do. Use the available OS and Docker features for enhancing security. Monitor your systems for anomalous behavior. If you take all these steps, you’ll ward off the large majority of threats to your Docker environment.

Tags Share this article 11/25/21 Published Nick Ellsmore is an Australian cybersecurity professional whose thoughts on the future of cybersecurity are always insightful. Having a deep respect for Nick, I really enjoyed listening to his latest podcast “Episode 79 Making the cyber sector redundant with Nick Ellsmore” . As Nick opened the door to debate on “all the mildly controversial views” he has put forward in the podcast, I decided to take a stab at a couple of points made by Nick. For some mysterious reason, these points have touched my nerve. So, here we go. Nick: The cybersecurity industry, we spent so long trying to get people to listen to us and take the issue seriously, you know, we’re now getting that, you know. Are the businesses really responding because we were trying to get people to listen to us? Let me rephrase this question. Are the businesses really spending more on cybersecurity because we were trying to get people to listen to us? The “cynical me” tells me No. Businesses are spending more on cybersecurity because they are losing more due to cyber incidents. It’s not the number of incidents; it’s their impact that is increasingly becoming devastating. Over the last ten years, there were plenty of front-page headliners that shattered even seemingly unshakable businesses and government bodies. Think of Target attack in 2013, the Bank of Bangladesh heist in 2016, Equifax breach in 2017, SolarWinds hack in 2020 .. the list goes on. We all know how Uber tried to bribe attackers to sweep the stolen customer data under the rug. But how many companies have succeeded in doing so without being caught? How many cyber incidents have never been disclosed? These headliners don’t stop. Each of them is another reputational blow, impacted stock options, rolled heads, stressed-out PR teams trying to play down the issue, knee-jerk reaction to acquire snake-oil-selling startups, etc. We’re not even talking about skewed election results (a topic for another discussion). Each one of them comes at a considerable cost. So no wonder many geniuses now realise that spending on cybersecurity can actually mitigate those risks. It’s not our perseverance that finally started paying off. It’s their pockets that started hurting. Nick: I think it’s important that we don’t lose sight of the fact that this is actually a bad thing to have to spend money on. Like, the reason that we’re doing this is not healthy. .. no one gets up in the morning and says, wow, I can’t wait to, you know, put better locks on my doors. It’s not the locks we sell. We sell gym membership. We want people to do something now to stop bad things from happening in the future. It’s a concept of hygiene, insurance, prevention, health checks. People are free not to pursue these steps, and run their business the way they used to .. until they get hacked, get into the front page, wondering first “Why me?” and then appointing a scapegoat. Nick: And so I think we need to remember that, in a sense, our job is to create the entire redundancy of this sector. Like, if we actually do our job, well, then we all have to go and do something else, because security is no longer an issue. It won’t happen due to 2 main reasons. Émile Durkheim believed in a “society of saints”. Unfortunately, it is a utopia. Greed, hunger, jealousy, poverty are the never-ending satellites of the human race that will constantly fuel crime. Some of them are induced by wars, some — by corrupt regimes, some — by sanctions, some — by imperfect laws. But in the end — there will always be Haves and Have Nots, and therefore, fundamental inequality. And that will feed crime. “Errare humanum est” , Seneca. To err is human. Because of human errors, there will always be vulnerabilities in code. Because of human nature (and as its derivative, geopolitical or religious tension, domination, competition, nationalism, fight for resources), there will always be people willing to and capable of exploiting those vulnerabilities. Mix those two ingredients — and you get a perfect recipe for cybercrime. Multiply that with never-ending computerisation, automation, digital transformation, and you get a constantly growing attack surface. No matter how well we do our job, we can only control cybercrime and keep the lid on it, but we can’t eradicate it. Thinking we could would be utopic. Another important consideration here is budget constraints. Building proper security is never fun — it’s a tedious process that burns cash but produces no tangible outcome. Imagine a project with an allocated budget B to build a product P with a feature set F, in a timeframe T. Quite often, such a project will be underfinanced, potentially leading to a poor choice of coders, overcommitted promises, unrealistic expectations. Eventually leading to this (oldie, but goldie): Add cybersecurity to this picture, and you’ll get an extra step that seemingly complicates everything even further: The project investors will undoubtedly question why that extra step was needed. Is there a new feature that no one else has? Is there a unique solution to an old problem? None of that? Then what’s the justification for such over-complication? Planning for proper cybersecurity built-in is often perceived as FUD. If it’s not tangible, why do we need it? Customers won’t see it. No one will see it. Scary stories in the press? Nah, that’ll never happen to us. In some way, extra budgeting for cybersecurity is anti-capitalistic in nature. It increases the product cost and, therefore, its price, making it less competitive. It defeats the purpose of outsourcing product development, often making outsourcing impossible. From the business point of view, putting “Sec” into “DevOps” does not make sense. That’s Ok. No need. .. until it all gloriously hits the fan, and then we go back to STEP 1. Then, maybe, just maybe, the customer will say, “If we have budgeted for that extra step, then maybe we would have been better off”.
