Tags Share this article 9/29/21 Published Tsippi Dach, Director of Communications at AlgoSec, explores what happened during this past summer’s Fastly outage, and explores how your business can protect itself in the future. The odds are that before June 8th you probably hadn’t heard of Fastly unless you were a customer. It was only when swathes of the internet went down with the 503: Service Unavailable error message that the edge cloud provider started to make headlines . For almost an hour, sites like Amazon and eBay were inaccessible, costing millions of dollars’ worth of revenue. PayPal, which processed roughly $106 million worth of transactions per hour throughout 2020, was also impacted, and disruption at Shopify left thousands of online retail businesses unable to serve customers. While the true cost of losing a significant portion of the internet for almost one hour is yet to be tallied, we do know what caused it. What is Fastly and why did it break the internet? Fastly is a US-based content distribution network (CDN), sometimes referred to as an ‘edge cloud provider.’ CDNs relieve the load on a website’s servers and ostensibly improve performance for end-users by caching copies of web pages on a distributed network of servers that are geographically closer to them. The downside is that when a CDN goes down – due to a configuration error in Fastly’s case – it reveals just how vulnerable businesses are to forces outside of their control. Many websites, perhaps even yours, are heavily dependent on a handful of cloud-based providers. When these providers experience difficulties, the consequences for your business are amplified ten-fold. Not only do you run the risk of long-term and costly disruption, but these weak links can also provide a golden opportunity for bad actors to target your business with malicious software that can move laterally across your network and cause untold damage. How micro-segmentation can help The security and operational risks caused by these outages can be easily mitigated by implementing plans that should already be part of an organization’s cyber resilience strategy. One aspect of this is micro-segmentation , which is regarded as one of the most effective methods to limit the damage of an intrusion or attack and therefore limit large-scale downtime from configuration misfires and cyberattacks. Micro-segmentation is the act of creating secure “zones” in data centers and cloud deployments that allow your company to isolate workloads from one another. In effect, this makes your network security more compartmentalized, so that if a bad actor takes advantage of an outage in order to breach your organization’s network, or user error causes a system malfunction, you can isolate the incident and prevent lateral impact. Simplifying micro-segmentation with AlgoSec Security Management Suite The AlgoSec Security Management Suite employs the power of automation to make it easy for businesses to define and enforce their micro-segmentation strategy, ensuring that it does not block critical business services, and also meets compliance requirements.

Tags Share this article 3/19/23 Published As organizations respond to an ever-evolving set of security threats, network teams are scrambling to find new ways to keep up with numerous standards and regulations to dodge their next compliance audit violation. Can this nightmare be avoided? Yes, and it’s not as complex as one might think if you take a “compliance first” approach . It may not come as a surprise to many, but the number of cyber attacks is increasing every year and with it the risk to companies’ financial, organizational, and reputational standing. What’s at stake? The stakes are high when it comes to cyber security compliance. A single data breach can result in massive financial losses, damage to a company’s reputation, and even jail time for executives. Data breaches: Data breaches are expensive and becoming even more so by the day. According to the Ponemon Institute’s 2022 Cost of a Data Breach Report , the average cost of a data breach is $4.35 million. Fraud: Identity fraud is one of the most pressing cybersecurity threats today. In large organizations, the scale of fraud is also usually large, resulting in huge losses causing depletion of profitability. In a recent survey done by PwC, nearly one in five organizations said that their most disruptive incident cost over $50 million*. Theft: Identity theft is on the rise and can be the first step towards compromising a business. According a study from Javelin Strategy & Research found that identity fraud costs US businesses an estimated total of $56 billion* in 2021. What’s the potential impact? The potential impact of non-compliance can be devastating to an organization. Financial penalties, loss of customers, and damage to reputation are just a few of the possible consequences. To avoid these risks, organizations must make compliance a priority and take steps to ensure that they are meeting all relevant requirements. Legal impact:  Regulatory or legal action brought against the organization or its employees that could result in fines, penalties, imprisonment, product seizures, or debarment.  Financial impact:  Negative impacts with regard to the organization’s bottom line, share price, potential future earnings, or loss of investor confidence.  Business impact:  Adverse events, such as embargos or plant shutdowns, could significantly disrupt the organization’s ability to operate.  Reputational impact:  Damage to the organization’s reputation or brand—for example, bad press or social-media discussion, loss of customer trust, or decreased employee morale.  How can this be avoided? In order to stay ahead of the ever-expanding regulatory requirements, organizations must adopt a “compliance first” approach to cyber security. This means enforcing strict compliance criteria and taking immediate action to address any violations to ensure data is protected. Some of these measures include the following: Risk assessment: Conduct ongoing monitoring of compliance posture (risk assessment) and conduct regular internal audits (ensuring adherence with regulatory and legislative requirements (HIPAA, GDPR, PCI DSS, SOX, etc.) Documentation: Enforce continuous tracking of changes and intent Annual audits: Commission 3rd party annual audits to ensure adherence with regulatory and legislative requirements (HIPAA, GDPR, PCI DSS, SOX, etc.) Conclusion and next steps Compliance violations are no laughing matter. They can result in fines, business loss, and even jail time in extreme cases. They can be difficult to avoid unless you take the right steps to avoid them. You have a complex set of rules and regulations to follow as well as numerous procedures, processes, and policies. And if you don’t stay on top of things, you can end up with a compliance violation mess that is difficult to untangle. Fortunately, there are ways to reduce the risk of being blindsided by a compliance violation mess with your organization. Now that you know the risks and what needs to be done, here are six best practices for achieving it.

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.

IaC 2023 Cybersecurity Predictions and Best Practices 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 12/6/22 Published As 2022 comes to a close, Professor Avishai Wool, AlgoSec Co-Founder and CTO, provides his top 5 issues organizations will need to be aware in 2023 that will also dominate the cyber community conversation. 1) Application centric approach to network security will supersede basic NSPM I think the market has matured to the point where the NSPM approach has reached a tipping point and I see the shift to an application perspective becoming the de facto approach in network security policy management as there are better and more robust technologies in the market that can help organizations get there faster. I see this shift becoming even more viable in 2023 based on recent market trends in which organizations are opting for downsizing and trying to do more with the smaller staff at the expense of losing tribal knowledge. As a result, I see organizations shifting more towards adopting a holistic approach to network security that are more application centric in which they can retain critical knowledge, such as application traffic intent and application policy rules, so that the new generations can step in and pick up where the previous predecessors left off. 2) Containerization will enhance layered security I expect container security to be increasingly popular in the future, as companies understand that their existing network security mechanisms are not enough for the communication networks of today. Containers are seen as a cost-effective light-weight solution for deployment – and deploying them introduces another inner layer where security policies can be applied: behind the perimeter filters, the internal zoning, and the micro-segmentation, organizations can now also consider nano-segmentation at the container level. Vulnerability testing is another dimension of the container platform especially within cloud applications and SaaS products. The common Kubernetes platform offers both opportunities and challenges for vulnerability scanners. Beyond 2023 , businesses will need to enhance both their visibility and management capabilities of security within their containerized applications 3) Security driven IaaS ecosystems to improve network security I expect the popularity of Infrastructure as a service (IaaS) to continue to soar, making it difficult for security teams to keep up with the associated risks and vulnerabilities. Pre-set security settings may not meet the needs of the organization and customizing these settings can prove to be difficult. The customizability of IaaS offers great potential for productivity, but it also makes it complicated to secure. The bottom line is that companies can no longer depend on their network perimeter to guard sensitive data. In response, I anticipate organizations that begin utilizing an “Always-on Security” approach such as Infrastructure as Code (IaC) which would permit them to construct personalized policies to control the development environments during each phase of the software development life cycle (SDLC) and recognize potential risks, security flaws, and compliance issues on a what-if basis, before deploying flawed settings into production. 4) Cloud-native security tools will reign supreme I expect that cloud-based security systems will become more commonplace: these security solutions offer a wide range of abilities, such as secure access, identity and access management, data loss prevention, application security, automation of security, detection and prevention of intrusions, security information and event management, and encryption. With companies transitioning more workloads to the cloud, they will want to make use of many of these features. These tools make it possible for remote teams to manage a greater public cloud presence: comfortably configuring services and automating processes, to identify and preemptively tackle any kind of threats. To bridge the gap in cloud data security, I anticipate the emergence of data safeguarding systems that are designed specifically for cloud usage and are able to link up with public cloud systems in an advanced, agentless manner. This has been classified in the market as Cloud Native Application Protection Platform (CNAPP) . These platforms must be able to detect where the data is stored and what sorts of data are stored in the cloud, so that corporations can prioritize on what is most important – defending their most sensitive data and cloud-based applications without interfering with their normal operations. 5) Expect ransomware not to go away and get even more sophisticated Organizations in 2022 saw no let-up from ransomware threats, some of whom were attacked multiple times and I do not see any reason why this trend will change in 2023. Cyber criminals are getting more resourceful and savvier in their attempts to stay ahead of law enforcement, and I anticipate these attacks will only become more frequent as their perpetrators are proving more capable of infiltrating many organizations’ cyber defenses. In response, organizations will have to seek more technology solutions to protect data at the source. But that would not suffice. I think organizations will need to look beyond technological solutions and apply better preparedness strategies. Whether it be Zero Trust or something less overarching but more practical for an organization’s business needs, such as Micro-segmentation , it would ensure that threat-actors would not be able to access the data residing inside the security perimeter.

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.

Cloud Security Operation “Red Kangaroo”: Industry’s First Dynamic Analysis of 4M Public Docker Container Images 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 12/1/20 Published Linux containers aren’t new. In fact, this technology was invented 20 years ago. In 2013, Docker entered the scene and revolutionized Linux containers by offering an easy-to-use command line interface (CLI), an engine, and a registry server. Combined, these technologies have concealed all the complexity of building and running containers, by offering one common industry standard . As a result, Docker’s popularity has sky-rocketed, rivalling Virtual Machines, and transforming the industry. In order to locate and share Docker container images, Docker is offering a service called Docker Hub . Its main feature, repositories , allows the development community to push (upload) and pull (download) container images. With Docker Hub, anyone in the world can download and execute any public image, as if it was a standalone application. Today, Docker Hub accounts over 4 million public Docker container images . With 8 billion pulls (downloads) in January 2020 and growing , its annualized image pulls should top 100 billion this year. For comparison , Google Play has 2.7M Android apps in its store, with a download rate of 84 billion downloads a year. How many container images currently hosted at Docker Hub are malicious or potentially harmful? What sort of damage can they inflict? What if a Docker container image downloaded and executed malware at runtime? Is there a reliable way to tell that? What if a compromised Docker container image was downloaded by an unsuspecting customer and used as a parent image to build and then deploy a new container image into production, practically publishing an application with a backdoor built into it? Is there any way to stop that from happening? At Prevasio, we asked ourselves these questions multiple times. What we decided to do has never been done before. The Challenge At Prevasio, we have built a dynamic analysis sandbox that uses the same principle as a conventional sandbox that ‘detonates’ malware in a safe environment. The only difference is that instead of ‘detonating’ an executable file, such as a Windows PE file or a Linux ELF binary, Prevasio Analyzer first pulls (downloads) an image from any container registry, and then ‘detonates’ it in its own virtual environment, outside the organization/customer infrastructure. Using our solution, we then dynamically analyzed all 4 million container images hosted at Docker Hub. In order to handle such a massive volume of images, Prevasio Analyzer was executed non-stop for a period of one month on 800 machines running in parallel. The result of our dynamic scan reveals that: 51 percent of all containers had “critical” vulnerabilities, while 13 percent were classified as “high” and four percent as “moderate” vulnerabilities. Six thousand containers were riddled with cryptominers, hacking tools/pen testing frameworks, and backdoor trojans. While many cryptominers and hacking tools may not be malicious per se, they present a potentially unwanted issue to an enterprise. More than 400 container images (with nearly 600,000 pulls) of weaponized Windows malware crossing over into the world of Linux. This crossover is directly due to the proliferation of cross-platform code (e.g. GoLang, .NET Core and PowerShell Core). Our analysis of malicious containers also shows that quite a few images contain a dynamic payload. That is, an image in its original form does not have a malicious binary. However, at runtime, it might be scripted to download a source of a coinminer, to then compile and execute it. A dynamic analysis sandbox, such as Prevasio Analyzer, is the only solution that provides a behavioral analysis of Docker containers. It is built to reveal malicious intentions of Docker containers by executing them in its own virtual environment, revealing a full scope of their behavior.

Background The customer is one of the world’s leading integrated energy companies. Through its worldwide subsidiaries, the company is involved in virtually every facet of the energy industry. The company explores for, produces and transports crude oil and natural gas; refines, markets and distributes transportation fuels and lubricants; manufactures and sells petrochemicals and additives; generates power; and develops and deploys technologies that enhance business value in every aspect of the company’s operations. They are listed on the Fortune 50 and a component of the S&P 100. The Challenge The customer has over 900 firewalls throughout the world, including in several remote sites. Some of their challenges included: Overly broad firewall policies Risky firewall rules Pressure from legal and compliance teams Manual processes and difficulty implementing automation Lack of visibility into security policies throughout the network “Before AlgoSec, we didn’t manage our firewalls very well,” stated Jeremy Haynes, a Solution Architect at the energy company. “We did not have a good enforcement and validation tool to verify that policies were accurate and did not introduce unacceptable risk.” The Solution The company was in the process of migrating from their previous firewall vendor to Palo Alto Networks. They used the opportunity for a fresh start to clean up and optimize their security policies. They were searching for a solution that provided: Automation of firewall policy management Identification of layer 7 (application-based) policies Innovative features that aligned with their strategic goals Strong support for Palo Alto Networks firewalls Following an in-depth evaluation, the company selected AlgoSec’s Security Policy Management Solution, which includes AlgoSec Horizon Security Analyzer and AlgoSec Horizon FireFlow (AFF). AlgoSec Horizon Security Analyzer ensures security and compliance by providing visibility and analysis into complex network security policies. AlgoSec Horizon FireFlow improves security and saves security staffs’ time by automating the entire security policy change process, eliminating manual errors, and reducing risk. The Results By using the AlgoSec Security Management Solution, the company was able to clean up risky firewall policies, reduce misconfigurations, and dedicate more workers to business-driven innovation instead of security policy maintenance. Some benefits gained include: Compliance with internal requirements Ability to map out their network and maintain network segmentation Less time needed to maintain firewall policies Easier time managing hundreds of firewalls spread out worldwide AlgoSec enabled their network segmentation initiatives. By mapping their network, and determining what zones should communicate with each other, they were able to fix existing policies that broke segmentation rules and not break segmentation policies in the future. This helped ensure a state of continuous compliance. “AlgoSec gives us an easy to read and present view of firewall compliance. This helps our business units ensure their policies are clean. We can also demonstrate that the firewalls connected to our network, but owned by other business units, meet our standards,” according to Haynes. They have over 1,700 change requests daily and therefore automation is crucial. “The ability to work with Ansible, ServiceNow, and Palo Alto gives us the ability to automate our firewall policy creation. It does so in a manner where we do not have to worry about a policy being created that may put our organization at risk,” continued Haynes. AlgoSec helps the company to not only quickly deploy firewall policies but also ensure the security of the business. “We want to make sure our money-making capabilities can conduct their business with minimal impact and do their job. The ROI for us is our great assurance in the security of our firewall policies,” concluded Haynes. Schedule time with one of our experts
