Tags Share this article 9/8/22 Published As cloud adoption and digital transformation increases, more sensitive data from applications is being stored in data containers. This is why effective container security controls to securely manage application connectivity is an absolute must. AlgoSec CTO and Co-Founder, Prof. Avishai Wool provides some useful container security best practices to help you do just that. What is Container Security? Organizations, now more than ever, are adopting container technology. Instead of powering up servers and instances in the cloud, they are using containers to run business applications. Securing these is equally as important as securing other digital assets that the business is dependent on. There are two main pillars to think about: The code: you want to be able to scan the containers and make sure that they are running legitimate code without any vulnerabilities. The network: you need to control access to and from the container (what it can connect to), both inside the same cluster, other clusters, and different parts of the network. How critical is container security to managing application connectivity risks? To understand the role of container security within the overall view of network security, there are three points to consider. First, if you’re only concerned about securing the containers themselves, then you’re looking at nano-segmentation , which involves very granular controls inside the applications. Second, if you’re thinking about a slightly wider scope then you may be more concerned with microsegmentation , where you are segmenting between clusters or between servers in a single environment. Here you will want to enforce security controls that determine the allowable communication between specific endpoints at specific levels. Finally, if the communication needs to go further, from a container inside one cluster within one cloud environment to an asset that’s outside of the data center, then that might need to go through broader segmentation controls such as zoning technologies, security groups or a firewall at the border. So, there are all these layers where you can place network security policies. When you’re looking at a particular connectivity request (say for a new version of an application) from the point of view of a given container you should ask yourself: what is the container connected to? What is it communicating with? Where are those other sides of the connectivity placed? Based on that determination, you will then know which security controls you need to configure to allow that connectivity through the network. How does containerization correlate with application centric security policy management? There are a number of different aspects to the relationship between container security and application security. If an application uses containers to power up workloads then container security is very much an integral part of application security. When you’re adding new functionality to an application, powering up additional containers, asking containers to perform new tasks whereby they need to connect to additional assets, then the connectivity of those containers needs to be secured. And security controls need to be regulated or changed based on what the application needs them to do. Another factor in this relationship is the structure of the application. All the containers that run and support the application are often located in one cluster or a micro-segment of the network. So, much of the communication takes place inside that cluster, between one container or another, all in the same cluster. However, some of it can go to another cluster or somewhere that’s not even containerized. This is actually a good thing from an application point of view as the container structure can be used to understand the application structure as well. Not sure about container orchestration? Here’s what to know Container orchestration is part of a bigger orchestration play which is, in general, related to the concept of infrastructure as code. You want to be able to power up an environment with all the assets it requires, and have it function simultaneously so you can duplicate it. There are various orchestration technologies that can be used to deploy the security policies for containers , which is an excellent way to maintain container-based applications in a consistent and repeatable manner. Then if you need to double it or multiply it by 100, you can get cookie-cutter copies of the same thing. How will container security solutions play out in the future? Organizations today have the technology to enforce security controls at the container level, but these controls are very granular and it’s time-consuming to set policies and enforce them, particularly with issues like staff or skills shortages. Looking ahead, companies are likely to take a hierarchical view where container-based security is controlled at the application level by app owners or developers, and at the broader levels to ensure that the measures deployed throughout the network have the same degree of sophistication. Procedures and tooling are all evolving, so we don’t have a definitive answer as to how this will all end up. What are organizations going to be doing? Where will they place their controls? Who has the power to make the changes? When newer technologies are deployed, customer adoption will be crucial to understanding what makes the most sense. This will be interesting as there will be multiple scenarios to help companies master their security blueprint as we move forward.

Lesson 1 In this lesson, Professor Wool examines next-generation firewalls and the granular capabilities they provide for improved control over applications and users. Next-Generation Firewalls: Overview of Application and User-Aware Policies Watch Lesson 2 In this lesson, Professor Wool examines the pros and cons of whitelisting and blacklisting policies and offers some recommendations on policy considerations. NGFWs – Whitelisting & Blacklisting Policy Considerations Watch Lesson 3 Next generation firewalls (NGFWs) allow you to manage security policies with much greater granularity, based on specific applications and users, which provides much greater control over the traffic you want to allow or deny. Today, NGFWs are usually deployed alongside traditional firewalls. Therefore change requests need to be written using each firewall type’s specific terminology; application names and default ports for NGFWs, and actual protocols and ports for traditional firewalls. This new lesson explains some of challenges of writing firewall rules for a mixed firewall environment, and how to address them. Managing Your Security Policy in a Mixed Next Gen and Traditional Firewall Environment Watch Lesson 4 As part of the blacklisting approach to application security, most NGFW vendors now offer their customers a subscription based service that provides periodic updates to firewall definitions and signatures for a great number of applications especially the malicious ones. In this lesson, Professor Wool discusses the pros and cons of this offering for cyber threat prevention. It also discusses the limitations of this service when home-grown applications are deployed in the enterprise, and provides a recommendation on how to solve this problem.

Explore micro-segmentation: a powerful security strategy. Discover real-world examples, top solutions, and key benefits for enhanced security and reduced risk. Micro-segmentation: Examples, solutions & top benefits Micro-segmentation: What it is, how it works, benefits Micro-segmentation means breaking down enterprise networks into multiple segments and using security policies to dictate how the data and applications in each segment will be accessed. These determinations are made by limiting traffic based on zero trust and least privilege principles. It provides a viable solution to flawed network security policies that weaken enterprise security. A micro-segmentation strategy enables organizations to reduce the size of their attack surface and make their networks safer against potential breaches. It also allows them to improve incident response, contain the impact of breaches, and maintain compliance with relevant laws and regulations. Schedule a Demo The need for micro-segmentation All organizations must protect their data centers with robust and effective firewall policies. Without these policies and associated security controls, smart and devious cybercriminals can easily hack into enterprise networks and systems. Micro-segmentation provides an effective way to install strong, clean, and easily-manageable security policies that help to create a more secure on-prem or hybrid cloud environment. This environment can keep traffic safe and block potential breaches from corrupting servers or compromising data. Moreover, creating multiple logical segments that are isolated from each other and enforced with least-privileged access keeps threat actors out of the network and also helps to contain a breach if it does happen. Schedule a Demo How micro-segmentation works Micro-segmentation can be applied in both on-prem data centers and cloud environments. It isolates network workloads which enable security teams to create security policies. These policies dictate the type of traffic passing in and out of each micro-segment. The policies are used to manage and create secure network segments and determine how these segments or zones will be accessed. They dictate how applications and workloads will access the resources they need, how they will share data within a system, and in which direction. Micro-segmentation also enables security teams to determine what kind of security or authentication measures are required for the environment. There are three main micro-segmentation approaches. Micro-segmentation works differently depending on which approach is adopted. Agent-based/host-based micro-segmentation Agent-based micro-segmentation utilizes a software agent deployed on the workload. It doesn’t rely on static network-level rules based on network ports or IP addresses. The agent allows security teams to enforce granular isolation, better control individual hosts, and implement automated segmentation policies with human-readable labels. Agent-based micro-segmentation security solutions are infrastructure-independent so they can be deployed across both data center and cloud infrastructure. One drawback of the method is that not all workloads can have an agent installed on them. Also, attackers can exploit the trust in the network with host firewall-based micro-segmentation. Network-based micro-segmentation Network-based micro-segmentation leverages the network infrastructure to enforce security policies. The policies are configured and enforced using access control lists (ACLs) or IP constructs. There’s no need to deploy agents on workloads. A drawback of this method is that the policies can only be enforced per endpoint, so network firewalls cannot distinguish between legitimate software and malware and will therefore block or allow both. Also, the policies are static, which can cause performance issues in more dynamic (e.g., cloud) environments. Finally, the approach can be complicated to manage when more granular micro-segments and a higher number of firewall rules are created. Hypervisor-based micro-segmentation This method depends on virtualized environments and hypervisors to create overlay networks and enforce micro-segmentation. The approach does not require network hardware changes. Also, its policy constructs are easy to learn for security teams. The chief drawback of the approach is that it doesn’t support bare metal servers, container workloads, or public cloud environments. Also, it doesn’t provide host-level visibility into its software, processes, vulnerabilities, etc. Schedule a Demo Examples of micro-segmentation One common example of micro-segmentation is the separation of development and testing environments from production environments. Granularly limiting the connections between these environments prevents careless or dangerous activities, such as using sensitive/live data for testing. Other examples include: Application micro-segmentation: Restricting access to sensitive data in applications to prevent unauthorized use or malicious exfiltration User micro-segmentation: Leveraging user identity services to control access to applications and services Tier-level micro-management: Separating application components to allow only authorized users to access specific components and keep unauthorized users out Schedule a Demo Network segmentation vs. Micro-segmentation Network segmentation divides the enterprise network into multiple security zones. In traditional data center environments, network segmentation is usually accomplished using firewalls, VLANs, and access control lists (ACLs). In more modern, cloud-based environments, Virtual Private Clouds (VPCs), subnets, and Security Groups (SGs). Microsoft Azure, for example, provides numerous network segmentation options, such as subscriptions (platform-powered separation between entities), virtual networks (isolated and secure networks to run virtual machines and applications), network security groups (access control mechanisms to control traffic between resources within a virtual network), and Azure firewall (a cloud-native stateful firewall-as-a-service to filter traffic flowing between cloud resources, the Internet, and on-premise). Regardless of the environment type, the zones created with network segmentation consist of multiple devices and applications. Admins can set access controls that permit only specific traffic between zones. Micro-segmentation is a more granular form of network segmentation. It involves placing each device or application within its own logically isolated segment instead of simply breaking a network into multiple, large segments. It thus provides more granular visibility and greater control than network segmentation. Unlike network segmentation which breaks the network based on north-south traffic (traffic running between clients and servers and crossing the security perimeter), micro-segmentation focuses on east-west traffic that moves laterally across and within the network. Moreover, it usually uses software policies and software-defined networking (SDN). With SDN, all network traffic is routed through an inspection point (e.g., a next-generation firewall) that can identify an attacker’s lateral movement and block inappropriate accesses to the network and its resources. Some SDN solutions, such as Cisco Application Centric Infrastructure (ACI), can automatically assign endpoints to logical security zones called endpoint groups (EPGs). These EPGs may have a contract that is used to control traffic flow between EPGs within the ACI fabric. Schedule a Demo Network segmentation challenges and how micro-segmentation Helps Dividing a network into multiple smaller segments can improve both its security and performance. Effective network segmentation allows security teams to spot an attack and act early to mitigate its impact and prevent its spread across the network. Even so, it can be challenging to implement network segmentation. For one, dividing the network into many VLANs and subnets requires a lot of manual effort. Also, the network may need to be re-architected, which can be difficult, time-consuming, and expensive. Micro-segmentation is a better and easier approach to securing a network, especially if host-based micro-segmentation is adopted. This is because the host-based approach is infrastructure-independent, provides more granular control, and enables micro-segmentation based on human-understandable policies instead of static network-level rules. Plus, the model can be deployed across both, cloud and data center environments without “coupling” to them. In addition, it decouples security policy enforcement from the physical infrastructure, simplifying administration and allowing more granular control. Also, it does not require network re-architecting so it is less time-consuming, less complex, and more cost-effective than network segmentation. Schedule a Demo Micro-segmentation: Essential for zero trust security Micro-segmentation is increasingly used to implement zero trust security . This new security model considers all users and devices untrustworthy by default. To gain access to network resources and become “trusted”, the user or device must meet the network’s conditions, for example, undergo a virus scan or complete multi-factor authentication (MFA). The zero trust model enables organizations to move away from traditional perimeter-based network security which is inadequate for modern-day remote workers and cloud environments. And micro-segmentation supports the model by: Dividing the network into smaller zones Creating a mini-perimeter around each endpoint to secure it individually Providing enhanced network visibility and stronger access controls In sum, zero trust, and micro-segmentation work in tandem by securing workloads in dynamic environments and preventing the lateral movement of unauthorized users in the network. Schedule a Demo The top 7 benefits of micro-segmentation The need for micro-segmentation is increasing because it provides all these benefits: Effective security through enhanced endpoint protection Micro-segmentation provides effective and cost-efficient security, particularly in modern network environments that are complex, dynamic, and fast-expanding. By logically dividing the data center into distinct security segments, it enables security architects to define security controls for each segment. This then reduces the size of the attack surface and enables the organization to better resist attacks or intrusions. Protection against network-based threats Micro-segmentation protects networks against network-based threats like DDoS attacks and WiFI attacks. It also allows admins to implement robust controls to restrict the flow of traffic on detecting a threat. Protection for cloud workloads and data Micro-segmentation can secure dynamic cloud systems, workloads, and data. With granular microsegments, security teams can easily monitor cloud traffic, identify suspicious or malicious traffic, and respond quickly once they detect dangerous breaches. Protection from advanced persistent threats (APTs) Individual micro-segments contain security checkpoints that help to keep cyber threats from spreading across the network. So, even if one part of a network is compromised, attackers cannot move laterally and reach or persist in other parts of the network. Thus, micro-segmentation protects the network from APTs. Improves breach containment Even if the network is breached, security staff can contain its impact with micro-segmentation. By monitoring traffic against secure policies, they can reduce the impact of a breach as well as their response time. Support for centralized policy management Organizations can use micro-segmentation to create and enforce granular security policies and to centralize policy management across networks. Without it, they would have to manually manage policies across a large fleet of devices and resources, which is a complex and time-consuming task. In addition, they can enforce zero-trust security policies, where access is allowed based on need, which can reduce the organization’s cyber risk. Endpoint separation enables regulatory compliance Micro-segmentation using the host-based approach helps isolate separately-secured endpoints, allowing security staff to easily control the traffic in systems that are subject to regulations. Policy granularity and visibility ensure that distributed devices are always protected by unified network security and also reduce the risks of non-compliant usage.

Firewall Change Management Firewall troubleshooting steps & solutions to common issues Tsippi Dach 2 min read Tsippi Dach 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 8/10/23 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.

Keeping track of everything and ensuring its security is like trying to herd cats in a hurricane. And hold on tight, because Gartner predicts that by 2027, global public cloud spending will blast past the $1 trillion mark! That's a whole lot of cloud to manage and secure. 2. Security's Unique Demands: The cloud's a shape-shifter, constantly changing and evolving. That means your attack surface is never static – it's more like a wriggling octopus with tentacles reaching everywhere. And if you're not careful, those tentacles can be riddled with vulnerabilities and misconfigurations, just waiting for a cyber-pirate to exploit them. Legacy security solutions? They're like trying to fight a dragon with a water pistol. They simply can't keep up with the cloud's dynamic nature, leaving you vulnerable to breaches, compliance failures, and a whole lot of financial pain.

The Threat Landscape: A Cyber-Jungle The cyber threat landscape is a dangerous jungle, and your cloud environment is the prized watering hole. McKinsey estimates that by 2025, cyberattacks will cost businesses a staggering $10.5 trillion annually! That's enough to make even the bravest cloud warrior tremble. And as if the cloud's inherent challenges weren't enough, you've got a relentless horde of cyber-criminals trying to breach your defenses. Just look at some of the major attacks in 2024: AT&T : 110 million customer phone records compromised – that's like losing a phone book the size of a small city! Ticketmaster : 560 million customer records stolen – a hacking collective hit the jackpot with this one! Dell : 49 million customers' data compromised through brute-force attacks – talk about a battering ram! Figure 2: Stolen Ticketmaster data on illicit marketplaces (Source: Bleeping Computer ) 4. Regulatory Pressures: The Compliance Gauntlet Navigating the world of compliance is like running a gauntlet – one wrong step and you'll get hit with a penalty. Without a crystal-clear view of your cloud resources, networks, applications, and data, you're practically walking blindfolded through a minefield. Poor visibility, suboptimal network segmentation, and inconsistent rules are the enemies of compliance. They're like cracks in your cloud fortress, just waiting for an auditor to exploit them.
