Tags Share this article 7/22/21 Published Prof. Avishai Wool discusses the complexities of mergers and acquisitions for application management and how organizations can securely navigate the transition It comes as no surprise that the number of completed Mergers and Acquisitions (M&As) dropped significantly during the early stages of the pandemic as businesses closed ranks and focused on surviving rather than thriving. However, as we start to find some reprieve, many experts forecast that we’ll see an upturn in activity. In fact, by the end of 2020, M&A experienced a sudden surge and finished the year with only a 3% decline on 2019 levels. Acquiring companies is more than just writing a cheque. There are hundreds of things to consider both big and small, from infrastructure to staffing, which can make or break a merger. With that in mind, what do businesses need to do in order to ensure a secure and successful transition? When two worlds collide For many businesses, a merger or acquisition is highly charged. There’s often excitement about new beginnings mixed with trepidation about major business changes, not least when it comes to IT security. Mergers and acquisitions are like two planets colliding, each with their own intricate ecosystem. You have two enterprises running complex IT infrastructures with hundreds if not thousands of applications that don’t just simply integrate together. More often than not they perform replicated functions, which implies that some need to be used in parallel, while others need to be decommissioned and removed. This means amending, altering, and updating thousands of policies to accommodate new connections, applications, servers, and firewalls without creating IT security risks or outages. In essence, from an IT security perspective, a merger or acquisition is a highly complicated project that, if not planned and implemented properly, can have a long-term impact on business operations. Migrating and merging infrastructures One thing a business will need before it can even start the M&A process is an exhaustive inventory of all business applications spanning both businesses. An auto-discovery tool can assist here, collecting data from any application that is active on the network and adding it to a list. This should allow the main business to create a map of network connectivity flows which will form the cornerstone of the migration from an application perspective. Next comes security. A vulnerability assessment should be carried across both enterprise networks to identify any business-critical applications that may be put at risk. This assessment will give the main business the ability to effectively ‘rank’ applications and devices in terms of risk and necessity, allowing for priority lists to be created. This will help SecOps focus their efforts on crucial areas of the business that contain sensitive customer data, for instance. By following these steps you’ll get a clear organizational view of the entire enterprise environment and be able to identify and map all the critical business applications, linking vulnerabilities and cyber risks to specific applications and prioritize remediation actions based on business-driven needs. The power of automation While the steps outlined above will give you with an accurate picture of your IT topology and its business risk, this is only the first half of the story. Now you need to update security policies to support changes to business applications. Automation is critical when it comes to maintaining security during a merger or acquisition. An alarming number of data breaches are due to firewall misconfigurations, often resulting from attempts to change policies manually in a complex network environment. This danger increases with M&A, because the two merging enterprises likely have different firewall setups in place, often mixing traditional with next-generation firewalls or firewalls that come from different vendors. Automation is therefore essential to ensure the firewall change management process is handled effectively and securely with minimal risk of misconfigurations. Achieving true Zero-Touch automation in the network security domain is not an easy task but over time, you can let your automation solution run handsfree as you conduct more changes and gain trust through increasing automation levels step by step. Our Security Management Solution enables IT and security teams to manage and control all their security devices – from cloud controls in public clouds, SDNs, and on-premise firewalls from one single console. With AlgoSec you can automate time-consuming security policy changes and proactively assess risk to ensure continuous compliance. It is our business-driven approach to security policy management that enables organizations to reduce business risk, ensure security and continuous compliance, and drive business agility. Maintaining security throughout the transition A merger or acquisition presents a range of IT challenges but ensuring business applications can continue to run securely throughout the transition is critical. If you take an application centric approach and utilize automation, you will be in the best position for the merger/migration and will ultimately drive long term success.

AWS NACL best practices: How to combine security groups with network ACLs effectively Prof. Avishai Wool 2 min read Prof. Avishai Wool 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 8/28/23 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.

Firewall Change Management How to secure your LAN (Local Area Network) Matthew Pascucci 2 min read Matthew Pascucci 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 11/12/13 Published How to Secure Your Local Area Network In my last blog series we reviewed ways to protect the perimeter of your network and then we took it one layer deeper and discussed securing the DMZ . Now I’d like to examine the ways you can secure the Local Area Network, aka LAN, also known as the soft underbelly of the beast. Okay, I made that last part up, but that’s what it should be called. The LAN has become the focus of attack over the past couple years, due to companies tightening up their perimeter and DMZ. It’s very rare you’ll you see an attacker come right at you these days, when they can trick an unwitting user into clicking a weaponized link about “Cat Videos” (Seriously, who doesn’t like cat videos?!). With this being said, let’s talk about a few ways we can protect our soft underbelly and secure our network. For the first part of this blog series, let’s examine how to secure the LAN at the network layer. LAN and the Network Layer From the network layer, there are constant things that can be adjusted and used to tighten the posture of your LAN. The network is the highway where the data traverses. We need protection on the interstate just as we need protection on our network. Protecting how users are connecting to the Internet and other systems is an important topic. We could create an entire series of blogs on just this topic, but let’s try to condense it a little here. Verify that you’re network is segmented – it better be if you read my last article on the DMZ – but we need to make sure nothing from the DMZ is relying on internal services. This is a rule. Take them out now and thank us later. If this is happening, you are just asking for some major compliance and security issues to crop up. Continuing with segmentation, make sure there’s a guest network that vendors can attach to if needed. I hate when I go to a client/vendor’s site and they ask me to plug into their network. What if I was evil? What if I had malware on my laptop that’s now ripping throughout your network because I was dumb enough to click a link to a “Cat Video”? If people aren’t part of your company, they shouldn’t be connecting to your internal LAN plain and simple. Make sure you have egress filtering on your firewall so you aren’t giving complete access for users to pillage the Internet from your corporate workstation. By default users should only have access to port 80/443, anything else should be an edge case (in most environments). If users need FTP access there should be a rule and you’ll have to allow them outbound after authorization, but they shouldn’t be allowed to rush the Internet on every port. This stops malware, botnets, etc. that are communicating on random ports. It doesn’t protect everything since you can tunnel anything out of these ports, but it’s a layer! Set up some type of switch security that’s going to disable a port if there are different or multiple MAC addresses coming from a single port. This stops hubs from being installed in your network and people using multiple workstations. Also, attempt to set up NAC to get a much better understating of what’s connecting to your network while giving you complete control of those ports and access to resources from the LAN. In our next LAN security-focused blog, we’ll move from the network up the stack to the application layer.

Uncategorized Top 6 Hybrid Cloud Security Solutions: Key Features for 2024 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 1/15/24 Published Hybrid cloud security uses a combination of on-premises equipment, private cloud deployments, and public cloud platforms to secure an organization’s data, apps, and assets. It’s vital to the success of any organization that uses hybrid cloud network infrastructure. The key factors that make hybrid cloud security different from other types of security solutions are flexibility and agility. Your hybrid cloud security solution must be able to prevent, detect, and respond to threats regardless of the assets they compromise. That means being able to detect anomalous behaviors and enforce policies across physical endpoints, cloud-hosted software-as-a-service (SaaS) deployments, and in public cloud data centers. You need visibility and control wherever your organization stores or processes sensitive data. What is Hybrid Cloud Security? To understand hybrid cloud security, we must first cover exactly what the hybrid cloud is and how it works. Hybrid cloud infrastructure generally refers to any combination of public cloud providers (like AWS, Azure, Google Cloud) and private cloud environments. It’s easy to predict the security challenges hosting some of your organization’s apps on public cloud infrastructure and other apps on its own private cloud. How do you gain visibility across these different environments? How do you address vulnerabilities and misconfiguration risks? Hybrid cloud architecture can create complex problems for security leaders. However, it provides organizations with much-needed flexibility and offers a wide range of data deployment options. Most enterprises use a hybrid cloud strategy because it’s very rare for a large organization to entrust its entire IT infrastructure to a single vendor. As a result, security leaders need to come up with solutions that address the risks unique to hybrid cloud environments. Key Features of Hybrid Cloud Security An optimized hybrid cloud security solution gives the organization a centralized point of reference for managing security policies and toolsets across the entire environment. This makes it easier for security leaders to solve complex problems and detect advanced threats before they evolve into business disruptions. Hybrid cloud infrastructure can actually improve your security posture if managed appropriately. Some of the things you can do in this kind of environment include: Manage security risk more effectively. Lock down your most sensitive and highly regulated data in infrastructure under your direct control, while saving on cloud computing costs by entrusting less sensitive data to a third party. Distribute points of failure. Diversifying your organization’s cloud infrastructure reduces your dependence on any single cloud platform. This amplifies many of the practical benefits of network segmentation. Implement Zero Trust. Hybrid cloud networks can be configured with strict access control and authentication policies. These policies should work without regard to the network’s location, providing a strong foundation for demonstrating Zero Trust . Navigate complex compliance requirements. Organizations with hybrid cloud infrastructure are well-prepared to meet strict compliance requirements that apply to certain regions, like CCPA or GDPR data classification . With the right tools, demonstrating compliance through custom reports is easy. Real-time monitoring and remediation . With the right hybrid cloud security solutions in place, you can gain in-depth oversight into cloud workloads and respond immediately to security incidents when they occur. How Do Hybrid Cloud Security Solutions Work? Integration with Cloud Platforms The first step towards building a hybrid cloud strategy is determining how your cloud infrastructure deployments will interact with one another. This requires carefully reviewing the capabilities of the major public cloud platforms you use and determining your own private cloud integration capabilities. You will need to ensure seamless operation between these platforms while retaining visibility over your entire network. using APIs to programmatically connect different aspects of your cloud environment can help automate some of the most time-intensive manual tasks. For example, you may need to manage security configurations and patch updates across many different cloud resources. This will be very difficult and time-consuming if done manually, but a well-integrated automation-ready policy management solution can make it easy. Security Controls and Measures Your hybrid cloud solution will also need to provide comprehensive tools for managing firewalls and endpoints throughout your environment. These security tools can’t work in isolation — they need consistent policies informed by observation of your organization’s real-world risk profile. That means you’ll need to deploy a centralized solution for managing the policies and rulesets these devices use, and continuously configure them to address the latest threats. You will also need to configure your hybrid cloud network to prevent lateral movement and make it harder for internal threat actors to execute attacks. This is achieved with network segmentation, which partitions different parts of your network into segments that do not automatically accept traffic from one another. Microsegmentation further isolates different assets in your network according to their unique security needs, allowing access only to an exclusive set of users and assets. Dividing cloud workloads and resources into micro-segmented network zones improves network security and makes it harder for threat actors to successfully launch malware and ransomware attacks. It reduces the attack surface and enhances your endpoint security capabilities by enabling you to quarantine compromised endpoints the moment you detect unauthorized activity. How to Choose a Hybrid Cloud Security Provider Your hybrid cloud security provider should offer an extensive range of features that help you optimize your cloud service provider’s security capabilities. It should seamlessly connect your security team to the cloud platforms it’s responsible for protecting, while providing relevant context and visibility into cloud security threats. Here are some of the key features to look out for when choosing a hybrid cloud security provider: Scalability and Flexibility. The solution must scale according to your hybrid environment’s needs. Changing security providers is never easy, and you should project its capabilities well into the future before deciding to go through with the implementation. Pay close attention to usage and pricing models that may not be economically feasible as your organization grows. SLAs and Compliance. Your provider must offer service-level agreements that guarantee a certain level of performance. These SLAs will also play an important role ensuring compliance requirements are always observed, especially in highly regulated sectors like healthcare. Security Posture Assessment. You must be able to easily leverage the platform to assess and improve your overall security posture in a hybrid cloud model. This requires visibility and control over your data, regardless of where it is stored or processed. Not all hybrid cloud security solutions have the integrations necessary to make this feasible. DevSecOps Integration. Prioritize cloud security providers that offer support for integrating security best practices into DevOps, and providing security support early in the software development lifecycle. If your organization plans on building continuous deployment capabilities now or in the future, you will need to ensure your cloud security platform is capable of supporting those workflows.

Cyber Attacks & Incident Response Stop hackers from poisoning the well: Protecting critical infrastructure against cyber-attacks 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 3/31/21 Published Attacks on water treatment plants show just how vulnerable critical infrastructure is to hacking – here’s how these vital services should be protected. Criminals plotting to poison a city’s water supply is a recurring theme in TV and movie thrillers, such as 2005’s Batman Begins. But as we’ve seen recently, it’s more than just a plot device: it’s a cyber-threat which is all too real. During the past 12 months, there have been two high-profile attacks on water treatment systems that serve local populations, both with the aim of causing harm to citizens. The first was in April 2020, targeting a plant in Israel . Intelligence sources said that hackers gained access to the plant and tried altering the chlorine levels in drinking water – but luckily the attack was detected and stopped. And in early February, a hacker gained access to the water system of Oldsmar, Florida and tried to pump in a dangerous amount of sodium hydroxide. The hacker succeeded in starting to add the chemical, but luckily a worker spotted what was happening and reversed the action. But what could have happened if those timely interventions had not been made? These incidents are a clear reminder that critical national infrastructure is vulnerable to attacks – and that those attacks will keep on happening, with the potential to impact the lives of millions of people.  And of course, the Covid-19 pandemic has further highlighted how essential critical infrastructure is to our daily lives. So how can better security be built into critical infrastructure systems, to stop attackers being able to breach them and disrupt day-to-day operations?  It’s a huge challenge, because of the variety and complexity of the networks and systems in use across different industry sectors worldwide. Different systems but common security problems For example, in water and power utilities, there are large numbers of cyber-physical systems consisting of industrial equipment such as turbines, pumps and switches, which in turn are managed by a range of different industrial control systems (ICS). These were not designed with security in mind:  they are simply machines with computerized controllers that enact the instructions they receive from operators.  The communications between the operator and the controllers are done via IP-based networks – which, without proper network defenses, means they can be accessed over the Internet – which is the vector that hackers exploit. As such, irrespective of the differences between ICS controls, the security challenges for all critical infrastructure organizations are similar:  hackers must be stopped from being able to infiltrate networks; if they do succeed in breaching the organization’s defenses, they must be prevented from being able to move laterally across networks and gain access to critical systems. This means  network segmentation  is one of the core strategies for securing critical infrastructure, to keep operational systems separate from other networks in the organization and from the public Internet and surround them with security gateways so that they cannot be accessed by unauthorized people. In the attack examples we mentioned earlier, properly implemented segmentation would prevent a hacker from being able to access the PC which controls the water plant’s pumps and valves. With damaging ransomware attacks increasing over the past year, which also exploit internal network connections and pathways to spread rapidly and cause maximum disruption,  organizations should also employ security best-practices to block or limit the impact of ransomware attacks  on their critical systems. These best practices have not changed significantly since 2017’s massive WannaCry and NotPetya attacks, so organizations would be wise to check and ensure they are employing them on their own networks. Protecting critical infrastructure against cyber-attacks is a complex challenge because of the sheer diversity of systems in each sector.  However, the established security measures we’ve outlined here are extremely effective in protecting these vital systems – and in turn, protecting all of us.
