Tags Share this article 10/25/23 Published Fortified network security requires getting a variety of systems and platforms to work together. Security teams need to scan for potential threats, look for new vulnerabilities in the network, and install software patches in order to keep these different parts working smoothly. While small organizations with dedicated cybersecurity teams may process these tasks manually at first, growing audit demands will quickly outpace their capabilities. Growing organizations and enterprises rely on automation to improve IT security auditing and make sure their tech stack is optimized to keep hackers out. Network Security Audit Tools Explained Network Security Audit Tools provide at-a-glance visibility into network security operations and infrastructure. They scan network security tools throughout the environment and alert administrators of situations that require their attention. These situations can be anything from emerging threats, newly discovered vulnerabilities, or newly released patches for important applications. Your network security audit tools provide a centralized solution for managing the effectiveness of your entire security tech stack – including cloud-based software solutions and on-premises tools alike. With such a wide set of responsibilities, it should come as no surprise that many audit tools differ widely from one another. Some are designed for easy patch management while others may focus on intrusion detection or sensitive data exfiltration. Major platforms and operating systems may even include their own built-in audit tools. Microsoft Windows has an audit tool that focuses exclusively on Active Directory. However, enterprise security teams don’t want to clutter their processes with overlapping tools and interfaces – they want to consolidate their auditing tools onto platforms that allow for easy management and oversight. Types of Network Security Audit Tools Firewall Auditing Tools Firewall security rules provide clear instructions to firewalls on what kind of traffic is permitted to pass through. Firewalls can only inspect connections they are configured to detect . These rules are not static , however. Since the cybersecurity threat landscape is constantly changing, firewall administrators must regularly update their policies to accommodate new types of threats. At the same time, threat actors who infiltrate firewall management solutions can gain a critical advantage over their targets. They can change the organization’s security policies to ignore whatever malicious traffic they are planning on using to compromise the network. If these changes go unnoticed, even the best security technologies won’t be able to detect or respond to the threat. Security teams must regularly evaluate their firewall security policies to make sure they are optimized for the organization’s current risk profile. This means assessing the organization’s firewall rules and determining whether it is meeting its security needs. The auditing process may reveal overlapping rules, unexpected configuration changes , or other issues. Vulnerability Scanners Vulnerability scanners are automated tools that create an inventory of all IT assets in the organization and scan those assets for weak points that attackers may exploit. They also gather operational details of those assets and use that information to create a comprehensive map of the network and its security risk profile. Even a small organization may have thousands of assets. Hardware desktop workstations, laptop computers, servers, physical firewalls, and printers all require vulnerability scanning. Software assets like applications , containers, virtual machines, and host-based firewalls must also be scanned. Large enterprises need scanning solutions capable of handling enormous workloads rapidly. These tools provide security teams with three key pieces of information: Weaknesses that hackers know how to exploit . Vulnerability scanners work based on known threats that attackers have exploited in the past. They show security teams exactly where hackers could strike, and how. The degree of risk associated with each weakness . Since scanners have comprehensive information about every asset in the network, they can also predict the damage that might stem from an attack. This allows security teams to focus on high-priority risks first. Recommendations on how to address each weakness . The best vulnerability scanners provide detailed reports with in-depth information on how to mitigate potential threats. This gives security personnel step-by-step information on how to improve the organization’s security posture. Penetration Testing Tools Penetration testing allows organizations to find out how resilient their assets and processes might be in the face of an active cyberattack. Penetration testers use the same tools and techniques hackers use to exploit their victims, showing organizations whether their security policies actually work. Traditionally, penetration testing is carried out by two teams of cybersecurity professionals. The “red team” attempts to infiltrate the network and access sensitive data while the “blue team” takes on defense. Cybersecurity professionals should know how to use the penetration testing tools employed by hackers and red team operatives. Most of these tools have legitimate uses and are a fixture of many IT professionals’ toolkits. Some examples include: Port scanners . These identify open ports on a particular system. This can help users identify the operating system and find out what applications are running on the network. Vulnerability scanners . These search for known vulnerabilities in applications, operating systems, and servers. Vulnerability reports help penetration testers identify the most reliable entry point into a protected network. Network analyzers . Also called network sniffers, these tools monitor the data traveling through the network. They can provide penetration testers with information about who is communicating over the network, and what protocols and ports they are using. These tools help security professionals run security audits by providing in-depth data on how specific attack attempts might play out. Additional tools like web proxies and password crackers can also play a role in penetration testing, providing insight into the organization’s resilience against known threats.

Steps to Conduct a Network Security Audit Define the Scope : Start by defining the scope of your audit. You’ll need to determine which parts of your network and systems will be audited. Consider the goals and objectives of the audit, such as identifying vulnerabilities, ensuring compliance, or assessing overall security posture. Gather Information : Collect all relevant information about your network, including network diagrams, asset inventories, and existing security policies and procedures. This information will serve as a baseline for your audit. The more comprehensive this information is, the more accurate your audit results can be. Identify Assets : List all the assets on your network, including servers, routers, switches, firewalls, and endpoints. Ensure that you have a complete inventory of all devices and their configurations. If this information is not accurate, the audit may overlook important gaps in your security posture. Assess Vulnerabilities : Use network vulnerability scanning tools to identify vulnerabilities in your network. Vulnerability scanners like Nessus or OpenVAS can help pinpoint weaknesses in software, configurations, or missing patches. This process may take a long time if it’s not supported by automation. Penetration Testing : Conduct penetration testing to simulate cyberattacks and assess how well your network defenses hold up. Penetration testing tools like Metasploit or Burp Suite can help identify potential security gaps. Automation can help here, too – but the best penetration testing services emulate the way hackers work in the real world. Review Policies and Procedures : Evaluate the results of your vulnerability and penetration testing initiatives. Review your existing security policies and procedures to ensure they align with best practices and compliance requirements. Make necessary updates or improvements based on audit findings. Log Analysis : Analyze network logs to detect any suspicious or unauthorized activities. Log analysis tools like Splunk or ELK Stack can help by automating the process of converting log data into meaningful insights. Organizations equipped with SIEM platforms can analyze logs in near real-time and continuously monitor their networks for signs of unauthorized behavior. Review Access Controls : Ensure the organization’s access control policies are optimal. Review user permissions and authentication methods to prevent unauthorized access to critical resources. Look for policies and rules that drag down production by locking legitimate users out of files and folders they need to access. Firewall and Router Configuration Review: Examine firewall and router configurations to verify that they are correctly implemented and that access rules are up to date. Ensure that only necessary ports are open, and that the organization’s firewalls are configured to protect those ports. Prevent hackers from using port scanners or other tools to conduct reconnaissance. Patch Management : Check for missing patches and updates on all network devices and systems. Regularly update and patch software to address known vulnerabilities. Review recently patched systems to make sure they are still compatible with the tools and technologies they integrate with. Incident Response Plan : Review and update your incident response plan. Ensure the organization is prepared to respond effectively to security incidents, and can rely on up-to-date playbooks in the event of a breach. Compare incident response plans with the latest vulnerability scanning data and emerging threat intelligence information. Documentation and Reporting: Document all audit findings, vulnerabilities, and recommended remediation steps. Generate data visualizations that guide executives and other stakeholders through the security audit process and explain its results. Create a comprehensive report that includes an executive summary, technical details, and prioritized action items. Remediation : Implement the necessary changes and remediation measures to address the identified vulnerabilities and weaknesses. Deploy limited security resources effectively, prioritizing fixes based on their severity. Avoid unnecessary downtime when reconfiguring security tools and mitigating risk. Follow-Up Audits: Schedule regular follow-up audits to ensure that the identified vulnerabilities have been addressed and that security measures are continuously improved. Compare the performance metric data gathered through multiple audits and look for patterns emerging over time. Training and Awareness: Provide training and awareness programs for employees to enhance their understanding of security best practices and their role in maintaining network security. Keep employees well-informed about the latest threats and vulnerabilities they must look out for. FAQs What are some general best practices for network security auditing? Network security audits should take a close look at how the organization handles network configuration management over time. Instead of focusing only on how the organization’s current security controls are performing, analysts should look for patterns that predict how the organization will perform when new threats emerge in the near future. This might mean implementing real-time monitoring and measuring how long it takes for obsolete rules to get replaced. What is the ideal frequency for conducting network security audits? Network security audits should be conducted at least annually, with more frequent audits recommended for organizations with high-security requirements. Automated policy management platforms like AlgoSec can help organizations audit their security controls continuously. Are network security audit tools effective against zero-day vulnerabilities? Network security audit tools may not detect zero-day vulnerabilities immediately. However, they can still contribute by identifying other weaknesses that could be exploited in tandem with a zero-day vulnerability. They also provide information on how long it takes the organization to recognize new vulnerabilities once they are discovered. What should I look for when choosing a network security audit tool for my organization? Consider factors like the tool’s compatibility with your network infrastructure, reporting capabilities, support and updates, and its track record in identifying vulnerabilities relevant to your industry. Large enterprises highly value scalable tools that support automation. Can network security audit tools help with regulatory compliance? Yes, many audit tools offer compliance reporting features, helping organizations adhere to various industry and government regulations. Without an automated network security audit tool in place, many organizations would be unable to consistently demonstrate compliance. How long does it take to conduct a typical network security audit? The duration of an audit varies depending on the size and complexity of the network. A thorough audit can take anywhere from a few days to several weeks. Continuous auditing eliminates the need to disrupt daily operations when conducting audits, allowing security teams to constantly improve performance. What are the most common mistakes organizations make during network security audits? Common mistakes include neglecting to update audit tools regularly, failing to prioritize identified vulnerabilities, and not involving key stakeholders in the audit process. Overlooking critical assets like third-party user accounts can also lead to inaccurate audit results. What are some important capabilities needed for a Cloud-Based Security Audit? Cloud-based security audits can quickly generate valuable results by scanning the organization’s cloud-hosted IT assets for vulnerabilities and compliance violations. However, cloud-based audit software must be able to recognize and integrate third-party SaaS vendors and their infrastructure. Third-party tools and platforms can present serious security risks, and must be carefully inspected during the audit process. What is the role of Managed Service Providers (MSPs) in Network Security Auditing? MSPs can use audits to demonstrate the value of their services and show customers where improvement is needed. Since this improvement often involves the customer drawing additional resources from the MSP, comprehensive audits can improve the profitability of managed service contracts and deepen the connection between MSPs and their customers.

What is endpoint security and its functionality? Endpoint security tools protect individual devices like desktop workstations, laptop computers, and mobile phones from cyber attacks. This usually means installing an endpoint security client on the device which regularly scans for malware and inspects user behaviors to detect signs of unauthorized access. Mobile devices are particularly important to endpoint security because they can change location or get lost or stolen. Many advanced endpoint security tools offer additional features to detect malicious insiders who may have gained access to a legitimate user’s mobile device. What are firewalls in network security? Firewalls are devices that inspect network traffic. They typically sit at the edge of the network, protecting internal network assets from receiving malicious content from outside the network. Traditional firewalls look for packet and port data that indicates unauthorized activity and filter out connections that don’t appear legitimate. Next-generation firewalls offer a much wider range of capabilities to security teams. They can conduct deep packet inspection and identify traffic that belongs to particular apps or users. Some NGFW devices can even detect when sensitive data is being sent out of the network and block the attempt. What is Network Access Control (NAC)? Network access control solutions provide visibility into the actions users take on a network. They enable security teams to enforce access management policies on devices throughout the network. Without an NAC solution in place, security tools would have a much harder time recognizing users and devices based on their usage profiles, or managing permissions and authentication policies without using a separate access control solution. What is Zero Trust Network Access (ZTNA)? Zero Trust Network Access provides secure remote access to the data, applications, and service hosted on a network. It does this through a set of strictly defined access control policies that do not extend trust to users based on their previous behaviors. With a ZTNA policy in place, a malicious user who impersonates an employee and gains access to one segment of the network would not necessarily be able to move onto another segment of the network. How does Zero Trust secure cloud environments within enterprise networks? Cloud-enabled network infrastructure provides a more complex security profile than simple on-premises infrastructure. This is because the organization may not control the entire network, and it may not be able to establish boundaries for that network on its own. Security leaders need to deploy a more complex set of firewalls, proxies, and threat detection solutions to securely access cloud-hosted assets while still complying with Zero Trust. What is the Role of Network Segmentation in Reducing Attack Surface? Network segmentation puts obstacles up between different parts of the network. If attackers compromise one segment of the network, they will be unable to gain instant access to the rest of the network. Instead, they will have to spend additional time and resources breaking into other network segments. This increases the chance that security teams can detect the intruder and remediate the attack before catastrophic damage is done. What is Secure Access Service Edge (SASE)? SASE is an emerging concept that provides a level of security appropriate to complex cloud-enabled enterprises with distributed remote users. It combines wide area network (WAN) with network security services like CASB, firewall-as-a-service, and Zero Trust into a unified service delivered through the cloud. This gives security leaders real-time data on their cloud security posture and allows them to accurately assess network risks continuously. What is threat detection and threat intelligence? Threat detection tools include Intrusion Prevention Systems (IPS), sandboxes, and Security Information and Event Management platforms: Intrusion Prevention Systems (IPS) identify and block unauthorized network activity, often in conjunction with firewalls and other security tools. Sandboxing allows users to download and open suspicious files in a simulated IT environment. If the file launches malware, the sandbox application will close and delete the file without allowing it to harm the system. Security Information and Event Management (SIEM) platforms allow security operations personnel to conduct real-time monitoring and respond to threats as soon as they occur. How do network security solutions help with data loss prevention? (DLP) Network security tools prevent hackers from interacting with sensitive data and block attempts to exfiltrate that data and use it to extort users. DLP solutions help security teams identify and classify sensitive information so that they can put the appropriate security controls in place to protect it. Without this step, it would be very difficult to tell when data breaches result in the loss of protected data because security teams would not have a clear idea of where that data is. In addition to network security, many organizations are also relying on enterprise data backup and recovery solutions in the event of a disaster, their cloud data is preserved and easily retrievable. Can network security solutions help with email security? Some network security tools include valuable email security and anti-phishing features. For example, some next-generation firewalls can detect when authorized users attempt to input their login credentials on spoofed websites. They prevent the data from leaving the network and warn the user that they have been targeted by a phishing attack. Multi-layered security solutions are crucial to establishing secure workflows. What is the role of Virtual Private Networks (VPN) in Network Security? VPNs allow users to encrypt their traffic and interact with protected information even when they don’t trust their own internet connection. This is important for employees interacting with remote records while traveling, where hackers can easily create fake Wi-Fi hotspots designed to look like well-known public networks. Some VPNs also anonymize user identities, allowing them to access content they would not otherwise be able to. What is IoT’s impact on Network Security? The Internet of Things presents many challenges to operational security, especially for large enterprises and industrial organizations. IoT devices rarely benefit from the kind of built-in security protections that desktop workstations and mobile phones have, making them an easy target for hackers. Security leaders need to group IoT devices together and protect them with strict security policies enforced by high quality firewalls and other tools. Mitigating Distributed Denial of Service (DDoS Attacks) Hackers may attack organizations by preventing other users from accessing their services. They may even use these attacks to disrupt firewalls and create an opening through which they can launch additional attacks. Protecting network assets from DDoS attacks requires implementing firewalls that can detect these attacks and drop the malicious connections hackers are trying to make. Next-generation firewalls have additional resources available for doing this, and can even defend against complex multi-session attacks. What are network security best practices? Network security policies and firewall rules must balance the need for security with the need for easy and accessible workflows. If security tools prevent legitimate users from accessing the assets they need, it may impact production. Similarly, security leaders need to deploy limited resources efficiently. Automation helps ensure security team members can dedicate their time to important strategic initiatives instead of high-volume, low-impact tasks. What is the role of Managed Security Service Providers (MSSPs)? MSSPs help growing organizations enhance operational security without requiring them to build, deploy, and staff their own security operations center. This allows them to save a great deal of money compared to the cost of building in-house security capabilities. It also grants organizations access to specialist security talent they might not otherwise be able to afford. Instead of paying for unpredictable security expenditures, organizations can pay a consistent monthly fee according to the services they actually use.

Level Up Your Security Game: Time for a Mindset Reset! Hey everyone, and welcome! If you're involved in keeping your organization safe online these days, you're in the right place. For years, security felt like building a super strong castle with thick walls and a deep moat, hoping the bad guys would just stay outside. But let's be real, in our multi-cloud world, that castle is starting to look a little... outdated.

Hey everyone, and welcome! If you're involved in keeping your organization safe online these days, you're in the right place. For years, security felt like building a super strong castle with thick walls and a deep moat, hoping the bad guys would just stay outside. But let's be real, in our multi-cloud world, that castle is starting to look a little... outdated. Think about it: your apps and data aren't neatly tucked away in one place anymore. They're bouncing around on AWS, Azure, GCP, all sorts of platforms – practically everywhere! Trying to handle that with old-school security is like trying to catch smoke with a fishing net. Not gonna work, right? That's why we're chatting today. Gal Yosef, Head of Product Management in the U.S., gets it. He's helped us dive into some crucial mindset shifts – basically, new ways of thinking – that are essential for navigating the craziness of modern security. We gotta ditch the old ways and get ready to be more agile, work together better, and ultimately, be way more effective. Mindset Shift #1: From "Our Stuff is Safe Inside This Box" to "Trust Nothing, Verify Everything" Remember the good old days? We built a perimeter – firewalls, VPNs – thinking that everything inside was safe and sound (danger!). Security was all about guarding that edge. The Problem: Well, guess what? That world is gone! Multi-cloud environments have totally shattered that perimeter. Trying to just secure the network edge leaves your real treasures – your applications, users, and data – vulnerable as they roam across different clouds. It's like locking the front door but leaving all the windows wide open! The New Way: Distributed Trust. Security needs to follow your assets, wherever they go. Instead of just focusing on the infrastructure (the pipes and wires), we need to embrace Zero-Trust principles . Think of it like this: never assume anyone or anything is trustworthy, even if they're "inside." We need identity-based, adaptive security policies that constantly validate trust, rather than just assuming it based on location. Security becomes built into applications and workloads, not just bolted onto the network. Think of it this way: Instead of one big, guarded gate, you have individual, smart locks on every valuable asset. You're constantly checking who's accessing what, no matter where they are. It's like having a personal bodyguard for each of your important things, always making sure they have the right ID. Mindset Shift #2: From "My Team Handles Network Security, Their Team Handles Cloud Security" to "Let's All Be Security Buddies!" Ever feel like your network security team speaks a different language than your cloud security team? You're not alone! Traditionally, these have been separate worlds, with network teams focused on firewalls and cloud teams on security groups. The Problem: These separate silos are a recipe for confusion and fragmented security policies. Attackers? They love this! It's like having cracks in your armor. They aren't always going to bash down the front door; they're often slipping through the gaps created by this lack of communication. The New Way: Cross-functional collaboration. We need to tear down those walls! Network and cloud security teams need to work together, speaking a shared security language. Unified visibility and consistent policies across all your environments are key. Think of it like a superhero team – everyone has their own skills, but they work together seamlessly to fight the bad guys. Regular communication, shared tools, and a common understanding of the risks are crucial. Mindset Shift #3: From "Reacting When Something Breaks" to "Always Watching and Fixing Things Before They Do" Remember the old days of waiting for an alert to pop up saying something was wrong? That's like waiting for your car to break down before you even think about checking the oil. Not the smartest move, right? The Problem: In the fast-paced world of the cloud, waiting for things to go wrong is a recipe for disaster. Attacks can happen super quickly, and by the time you react, the damage might already be done. Plus, manually checking everything all the time? Forget about it – it's just not scalable when you've got stuff spread across multiple clouds. The New Way: Continuous & Automated Enforcement. We need to shift to a mindset of constant monitoring and automated security actions. Think of it like having a security system that's always on, always learning, and can automatically respond to threats in real-time. This means using tools and processes that continuously check for vulnerabilities, enforce security policies automatically, and even predict potential problems before they happen. It's like having a proactive security guard who not only watches for trouble but can also automatically lock doors and sound alarms the moment something looks fishy. Mindset Shift #4: From "Locking Everything Down Tight" to "Finding the Right Balance with Flexible Rules" We used to think the best security was the strictest security – lock everything down, say "no" to everything. But let's be honest, that can make it super hard for people to actually do their jobs! It's like putting so many locks on a door that nobody can actually get through it. The Problem: Overly restrictive security can stifle innovation and slow things down. Developers can get frustrated, and the business can't move as quickly as it needs to. Plus, sometimes those super strict rules can even create workarounds that actually make things less secure in the long run. The New Way: Flexible Guardrails. We need to move towards security that provides clear boundaries (the "guardrails") but also allows for agility and flexibility. Think of it like setting clear traffic laws – you know what's allowed and what's not, but you can still drive where you need to go. This means defining security policies that are adaptable to different cloud environments and business needs. It's about enabling secure innovation, not blocking it. We need to find that sweet spot where security empowers the business instead of hindering it. Mindset Shift #5: From "Security is a Cost Center" to "Security is a Business Enabler" Sometimes, security gets seen as just an expense, something we have to do but doesn't really add value. It's like thinking of insurance as just another bill. The Problem: When security is viewed as just a cost, it often gets underfunded or seen as a roadblock. This can lead to cutting corners and ultimately increasing risk. It's like trying to save money by neglecting the brakes on your car – it might seem cheaper in the short term, but it can have disastrous consequences later. The New Way: Security as a Business Enabler. We need to flip this thinking! Strong security isn't just about preventing bad things from happening; it's about building trust with customers, enabling new business opportunities, and ensuring the long-term resilience of the organization. Think of it like a strong foundation for a building – without it, you can't build anything lasting. By building security into our processes and products from the start, we can actually accelerate innovation and gain a competitive advantage. It's about showing our customers that we take their data seriously and that they can trust us. Wrapping Up: Moving to a multi-cloud world is exciting, but it definitely throws some curveballs at how we think about security. By adopting these five new mindsets, we can ditch the outdated castle mentality and build a more agile, collaborative, and ultimately more secure future for our organizations. It's not about being perfect overnight, but about starting to shift our thinking and embracing these new approaches. So, let's level up our security game together!

Learn how to effectively prevent and block ransomware attacks using your firewall. Discover essential configurations and best practices for enhanced security. Prevent & block ransomware attacks on firewall What is a ransomware attack? Ransomware is a malware attack that locks a victim’s data and demands a ransom, usually in Bitcoin, for its release. It often spreads through disguised executable files or malicious emails but can also exploit software vulnerabilities. A notable instance is the WannaCry attack, which spread without user interaction. Given the increasing sophistication of these attacks, understanding and combating ransomware is crucial for tightened cybersecurity. Schedule a Demo What are the main types of malware and ransomware threats? Understanding the variants of malware and ransomware infections in cybersecurity is critical to effective prevention and response. These threats can range from viruses to sophisticated Ransomware-as-a-Service models. Let’s delve into the main types: Viruses – Malicious software that can spread to other files and operating systems. Worms – Self-replicating malware spreading independently through networks, causing significant damage. Trojans – Disguised as legitimate software or files, Trojans can steal data or exploit permissions to gain unauthorized system access. Adware – This malware displays unwanted ads or pop-ups on a system, often for the attacker’s revenue generation. Fake pop-ups – Messages claiming your system has a virus and demanding payment for its removal, such as FakeAV and System Progressive Protection. Rootkits – Designed to hide their presence, rootkits enable remote access for malware, making it difficult for antivirus software to detect and remove the threats. Botnets – Attackers use these networks of compromised computers, known as botnets, to carry out remote DDoS and other cyber attacks. Spyware – This malware secretly monitors user activity and collects sensitive data. Fileless malware – Operating entirely in a system’s memory, this malware type is hard to detect and remove. Phishing emails – Disguised emails that trick recipients into clicking a malicious link or opening email attachments that appear authentic. Malvertising – Hackers inject malicious code into legitimate online advertising networks, redirecting users to malicious websites. Drive-by attacks – Users visit unsafe, fake web pages, including sites infected unknowingly or fake sites posing as legitimate ones. Self-propagation – Physically infects a system through a network or USB drive. Encryption ransomware – Encrypts your files and demands payment in return for the decryption key. Examples include CryptoLocker and WannaCry. Locker ransomware – A cyber threat restricting access to your system, demanding payment for restoring access. Winlocker and Police-themed ransomware are examples. Mobile ransomware – Targeting mobile devices, this ransomware locks the device or encrypts the files, demanding payment for their release. Android Defender and Simplelocker are examples. RaaS (Ransomware-as-a-Service) – Distributed as a service, this ransomware model allows anyone to buy or rent ransomware kits or apps for infecting others. Recognizing these threats is the first step toward ransomware prevention . Schedule a Demo Are firewalls able to provide ransomware protection? Yes, firewalls offer a layer of protection against ransomware. They act as a barrier between computers and networks, scanning incoming and outgoing traffic based on defined security parameters to block malicious packets. Firewalls can help thwart ransomware attacks by blocking suspect IP addresses, prohibiting remote access without authorization, and controlling the flow of certain data types that could carry ransomware. Schedule a Demo Which firewall rules can block ransomware? Several firewall rules can help block ransomware: Block known malicious IP addresses – You can configure firewalls to block traffic from IP addresses known to often distribute ransomware. Block all inbound traffic on port 445 – Used for file and printer sharing, port 445 is a common target for ransomware attacks. Restrict outbound traffic – Limiting outbound traffic to necessary ports can prevent a ransomware attack from communicating with its command and control server, thus halting the attack. Implement Geo-IP filtering – Some organizations may find it beneficial to block or limit traffic from specific countries or regions, particularly if they are known sources of ransomware. Disable Remote Desktop Protocol (RDP) – Many ransomware attacks exploit RDP to gain remote access to systems. Disabling RDP at the firewall can help prevent these advanced threats. Implement Intrusion Detection and Prevention Systems (IDS/IPS) – These systems can detect unusual traffic patterns or system activities that suggest a ransomware attack, allowing the firewall to respond and block the attack. Application control – Firewalls with application control features can prevent the execution of unrecognized or unauthorized applications, which can stop the delivery or execution of ransomware. Schedule a Demo What are the best practices for ransomware prevention? Clean up and tighten firewall rules Over time, firewall rules can get messy. This mess might let attackers in, just like weak VPNs or vulnerable email security can. Regularly cleaning up firewall and endpoint protection rules can help stop a ransomware attack . When you change a rule, make sure you know why. Misconfigured changes could disrupt apps or expose VPN tunnels. Analyze the risks and vulnerabilities in your network Every network security solution has some risks. These risks come from different providers. It is essential to find these risks and rank them based on how much they can harm your business. Since threats can pop up anytime, endpoint security with anti-malware features is essential. Focus on risks that could hurt critical business apps. Tying vulnerabilities to related firewall rules can make this easier, just like real-time updates in endpoint security can help stay ahead of new threats. Mitigate lateral movement and control east-west traffic with network segmentation Using network segmentation allows you to minimize the impact on your network in case of an attack. This is particularly effective against swift threats such as zero-day attacks, which target a software vulnerability that is unknown to the software vendor or to antivirus vendors. By securing crucial company data in protected segments with strong encryption keys and employing sandboxing, you are well-equipped to manage east-west traffic. East-west traffic refers to the communication or data transfer that happens inside the network, from server to server, or between internal applications. By managing this traffic, you can prevent attackers from moving laterally across your network. Adding multi-factor authentication can make this strategy even more robust. It adds another layer of security to keep attackers under control. For enhanced protection against cyber threats, consider implementing micro-segmentation . This advanced method can provide granular security controls and can further deter lateral movement across your network. Identify where your hybrid network is exposed to public networks In complex network setups with multi-cloud and hybrid systems, it is very important to see everything that is happening. You need to know how your business apps connect, including any vectors that unwanted or harmful traffic, such as bots, could use. To understand where your hybrid network is exposed to public networks, you need a complete map of your network and the ability to simulate traffic. This information can help you find and fix points where your network is exposed. Respond to incidents coming from SIEM/SOAR solutions with rapid isolation SIEM/SOAR systems collect and examine logs from your IT setup, security tools, and business apps. This helps the SOC team find and flag strange activities for further investigation. But with so much data, many alerts are false positives. Still, this does not mean you are lost in a sea of noise. By linking security incidents to network traffic patterns, you can tell if a compromised server is exposed to the internet. This can help you quickly separate an infected server if a Trojan gets past your defenses, which is a crucial strategy in stopping ransomware attacks. Schedule a Demo What steps must you take when a ransomware attack is detected? Step 1: Identify the attack – Act quickly if you think you are under a ransomware attack. Signs of an attack can include files you cannot open, weird computer activity, or a ransom message on your screen. If you see these, confirm it is ransomware and take steps to limit the damage. Step 2: Isolate affected systems – When you know you are under attack, isolate the affected computers from the rest of your network. This can stop the ransomware from spreading. You might need to disconnect from the internet, turn off Wi-Fi, or even shut down the system. Step 3: Secure backup data – Backups can help you recover from ransomware. If you have not already saved backups in a different place or offline, do it immediately to protect data from damage. Step 4: Report the incident – Tell your IT department or security team about the attack. If you do not have an IT team, you might need help from a cybersecurity company. Also, tell the law enforcement agencies and any organizations you are a part of that might need to know. Step 5: Preserve evidence – Keep any evidence related to the ransomware attack. This might include ransom messages, emails, or system logs. This evidence can help the police and cybersecurity experts understand what happened and might help get your data back. Step 6: Remove the ransomware – IT or cybersecurity experts should be the ones to get rid of the ransomware. They have special tools and methods to remove ransomware. Experts will ensure that it does not cause more harm to your files or computers. Step 7: Restore your systems – After the ransomware is gone, you can start fixing your systems. If you had backups that were not affected by the attack, you might be able to restore your systems to their previous state. If not, you might need a professional service to recover your data. Step 8: Post-incident review – Review what happened and how you responded. Find any weak spots in your security that the attack exploited and make a plan to improve your safety. This step can help stop future attacks and strengthen your business’s cybersecurity. Schedule a Demo How does AlgoSec prevent and mitigate ransomware attacks?

Firewall Change Management Firewall migration tips & best practices Joanne Godfrey 2 min read Joanne Godfrey 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. firewallmigration Tags Share this article 8/18/14 Published It goes without saying that security is the cornerstone of any organization today. This includes ensuring access to corporate data is secured, connectivity to the data center from both internal and external users is secured, and that critical security updates are installed. Now comes the big question: what if you have to migrate your security policy to a new platform? With cloud computing and distributed data centers across the world nothing in technology is ever constant anymore. So how do you control and manage a firewall migration? What if you use multiple vendors’ solutions with both virtual and physical appliances? A firewall migration can be as simple as moving from one model to another, or a lot more complicated. As an experienced cloud architect, I’ve been a part of a number of firewall migration projects. Here are three tips to help make your firewall migration project a little bit easier. Create powerful firewall and security visibility map. All aspects of your firewall must be documented and well planned before doing a migration, and you must plan for both current as well as future needs. Start by gathering information: create a visual, dynamic map of your firewall architecture and traffic, which should include all technical connectivity data. Understand, document and prepare policy migration. Once you have your visual firewall map it’s time to look under the hood. One firewall might be easy, but is it ever really just one security appliance? The dynamic nature of the modern data center means that multiple security vendors can live under one roof. So how do you create a policy migration plan around heterogeneous platforms? You need to identify and document all the security policies and services and network algorithms for each firewall end-point. Analyze business impact and create a migration path. How do your applications interact with various security policies? Do you have specific business units relying on specific firewall traffic? How are various data centers being segmented by your security policies? Migrating a firewall will have a business-wide impact. You must ensure that this impact is absolutely minimal. You need to understand how your entire business model interacts with firewall and security technologies and if any piece of the business is forgotten technological headaches may be the least of your worries. Migrating a firewall doesn’t have to be hard, but it must be well planned. With so much information traversing the modern data center, it’s imperative to have complete visibility across the security architecture. Ultimately, with the right tools to help you plan, map and actually implement a firewall change process, and lots of cups of coffee, you can greatly reduce security migration complexity. #FirewallMigration Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

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

If not, they won’t be around for long. The same is true in cloud computing. As more companies move their resources to the cloud, they must ensure efficient risk management to achieve resilience, availability, and integrity. Yes, moving to the cloud offers more advantages than on-premise environments. But, enterprises must remain meticulous because they have too much to lose. For example, they must protect sensitive customer data and business resources and meet cloud security compliance requirements. The key to these – and more – lies in cloud risk management. That’s why in this guide, we’ll cover everything you need to know about managing enterprise risk in cloud computing, the challenges you should expect, and the best ways to navigate it. If you stick around, we’ll also discuss the skills cloud architects need for risk management. What is Cloud Risk Management and Why is it Important? In cloud computing, risk management refers to the process of identifying, assessing, prioritizing, and mitigating the risks associated with cloud computing environments. It’s a process of being proactive rather than reactive. You want to identify and prevent an unexpected or dangerous event that can damage your systems before it happens. Most people will be familiar with Enterprise Risk Management (ERM). Organizations use ERM to prepare for and minimize risks to their finances, operations, and goals. The same concept applies to cloud computing. Cyber threats have grown so much in recent years that your organization is almost always a target. For example, a recent report revealed 80 percent of organizations experienced a cloud security incident in the past year. While cloud-based information systems have many security advantages, they may still be exposed to threats. Unfortunately, these threats are often catastrophic to your business operations. This is why risk management in cloud environments is critical. Through effective cloud risk management strategies, you can reduce the likelihood or impact of risks arising from cloud services. Types of Risks Managing risks is a shared responsibility between the cloud provider and the customer – you. While the provider ensures secure infrastructure, you need to secure your data and applications within that infrastructure. Some types of risks organizations face in cloud environments are: Data breaches are caused by unauthorized access to sensitive data and information stored in the cloud. Service disruptions caused by redundant servers can affect the availability of services to users. Non-compliance to regulatory requirements like CIS compliance , HIPAA, and GDPR. Insider threats like malicious insiders, cloud misconfigurations, and negligence. External threats like account hijacking and insecure APIs. But risk assessment and management aren’t always straightforward. You will face certain challenges – and we’ll discuss them below: Challenges Facing Enterprise Cloud Risk Management Most organizations often face difficulties when managing cloud or third-party/vendor risks. These risks are particularly associated with the challenges that cloud deployments and usage cause. Understanding the cloud security challenges sheds more light on your organization’s potential risks. The Complexity of Cloud Environments Cloud security is complex, particularly for enterprises. For example, many organisations leverage multi-cloud providers. They may also have hybrid environments by combining on-premise systems and private clouds with multiple public cloud providers. You’ll admit this poses more complexities, especially when managing configurations, security controls, and integrations across different platforms. Unfortunately, this means organizations leveraging the cloud will likely become dependent on cloud services. So, what happens when these services become unavailable? Your organisation may be unable to operate, or your customers can’t access your services. Thus, there’s a need to manage this continuity and lock-in risks. Lack of Visibility and Control Cloud consumers have limited visibility and control. First, moving resources to the public cloud means you’ll lose many controls you had on-premises. Cloud service providers don’t grant access to shared infrastructure. Plus, your traditional monitoring infrastructure may not work in the cloud. So, you can no longer deploy network taps or intrusion prevention systems (IPS) to monitor and filter traffic in real-time. And if you cannot directly access the data packets moving within the cloud or the information contained within them, you lack visibility or control. Lastly, cloud service providers may provide logs of cloud workloads. But this is far from the real deal. Alerts are never really enough. They’re not enough for investigations, identifying the root cause of an issue, and remediating it. Investigating, in this case, requires access to data packets, and cloud providers don’t give you that level of data. Compliance and Regulatory Requirements It can be quite challenging to comply with regulatory requirements. For instance, there are blind spots when traffic moves between public clouds or between public clouds and on-premises infrastructures. You can’t monitor and respond to threats like man-in-the-middle attacks. This means if you don’t always know where your data is, you risk violating compliance regulations. With laws like GDPR, CCPA, and other privacy regulations, managing cloud data security and privacy risks has never been more critical. Understanding Existing Systems and Processes Part of cloud risk management is understanding your existing systems and processes and how they work. Understanding the requirements is essential for any service migration, whether it is to the cloud or not. This must be taken into consideration when evaluating the risk of cloud services. How can you evaluate a cloud service for requirements you don’t know? Evolving Risks Organizations struggle to have efficient cloud risk management during deployment and usage because of evolving risks. Organizations often develop extensive risk assessment questionnaires based on audit checklists, only to discover that the results are virtually impossible to assess. While checklists might be useful in your risk assessment process, you shouldn’t rely on them. Pillars of Effective Cloud Risk Management – Actionable Processes Here’s how efficient risk management in cloud environments looks like: Risk Assessment and Analysis The first stage of every risk management – whether in cloud computing or financial settings – is identifying the potential risks. You want to answer questions like, what types of risks do we face? For example, are they data breaches? Unauthorized access to sensitive data? Or are they service disruptions in the cloud? The next step is analysis. Here, you evaluate the likelihood of the risk happening and the impact it can have on your organization. This lets you prioritize risks and know which ones have the most impact. For instance, what consequences will a data breach have on the confidentiality and integrity of the information stored in the cloud? Security Controls and Safeguards to Mitigate Risks Once risks are identified, it’s time to implement the right risk mitigation strategies and controls. The cloud provider will typically offer security controls you can select or configure. However, you can consider alternative or additional security measures that meet your specific needs. Some security controls and mitigation strategies that you can implement include: Encrypting data at rest and in transit to protect it from unauthorized access. For example, you could encrypt algorithms and implement secure key management practices that protect the information in the cloud while it’s being transmitted. Implementing accessing control and authentication measures like multi-factor authentication (MFA), role-based access control (RBAC), and privileged access management (PAM). These mechanisms ensure that only authorized users can access resources and data stored in the cloud. Network security and segmentation: Measures like firewalls, intrusion detection/intrusion prevention systems (IDS/IPS), and virtual private networks (VPN) will help secure network communications and detect/prevent malicious actors. On the other hand, network segmentation mechanisms help you set strict rules on the services permitted between accessible zones or isolated segments. Regulatory Compliance and Data Governance Due to the frequency and complexity of cyber threats, authorities in various industries are releasing and updating recommendations for cloud computing. These requirements outline best practices that companies must adhere to avoid and respond to cyber-attacks. This makes regulatory compliance an essential part of identifying and mitigating risks. It’s important to first understand the relevant regulations, such as PCI DSS, ISO 27001, GDPR, CCPA, and HIPAA. Then, understand each one’s requirements. For example, what are your obligations for security controls, breach notifications, and data privacy? Part of ensuring regulatory compliance in your cloud risk management effort is assessing the cloud provider’s capabilities. Do they meet the industry compliance requirements? What are their previous security records? Have you assessed their compliance documentation, audit reports, and data protection practices? Lastly, it’s important to implement data governance policies that prescribe how data is stored, handled, classified, accessed, and protected in the cloud. Continuous Monitoring and Threat Intelligence Cloud risks are constantly evolving. This could be due to technological advancements, revised compliance regulations and frameworks, new cyber-treats, insider threats like misconfigurations, and expanding cloud service models like Infrastructure-as-a-Service (IaaS). What does this mean for cloud computing customers like you? There’s an urgent need to conduct regular security monitoring and threat intelligence to address emerging risks proactively. It has to be an ongoing process of performing vulnerability scans of your cloud infrastructure. This includes log management, periodic security assessments, patch management, user activity monitoring, and regular penetration testing exercises. Incident Response and Business Continuity Ultimately, there’s still a chance your organization will face cyber incidents. Part of cloud risk management is implementing cyber incident response plans (CIRP) that help contain threats. Whether these incidents are low-level risks that were not prioritized or high-impact risks you missed, an incident response plan will ensure business continuity. It’s also important to gather evidence through digital forensics and analyze system artifacts after incidents. Backup and Recovery Implementing data backup and disaster recovery into your risk management ensures you minimize the impact of data loss or service disruptions. For example, backing up data and systems regularly is important. Some cloud services may offer redundant storage and versioning features, which can be valuable when your data is corrupted or accidentally deleted. Additionally, it’s necessary to document backup and recovery procedures to ensure consistency and guide architects. Best Practices for Effective Cloud Risk Management Achieving cloud risk management involves combining the risk management processes above, setting internal controls, and corporate governance. Here are some best practices for effective cloud risk management: 1. Careful Selection of Your Cloud Service Provider (CSP) Carefully select a reliable cloud service provider (CSP). You can do this by evaluating factors like contract clarity, ethics, legal liability, viability, security, compliance, availability, and business resilience. Note that it’s important to assess if the CSP relies on other service providers and adjust accordingly. 2. Establishing a Cloud Risk Management Framework Consider implementing cloud risk management frameworks for a structured approach to identifying, assessing, and mitigating risks. Some notable frameworks include: National Institute of Standards and Technology (NIST) Cloud Computing Risk Management Framework (CC RMF) ISO/IEC 27017 Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) Cloud Audit and Compliance (CAC) Criteria Center for Internet Security (CIS) Controls for Cloud, etc. 3. Collaboration and Communication with Stakeholders You should always inform all stakeholders about potential risks, their impact, and incident response plans. A collaborative effort can improve risk assessment and awareness, help your organization leverage collective expertise, and facilitates effective decision-making against identified risks. 4. Implement Technical Safeguards Deploying technical safeguards like cloud access security broker (CASB) in cloud environments can enhance security and protect against risks. CASB can be implemented in the cloud or on-premise and enforces security policies for users accessing cloud-based resources. 5. Set Controls Based on Risk Treatment After identifying risks and determining your risk appetite, it’s important to implement dedicated measures to mitigate them. Develop robust data classification and lifecycle mechanisms and integrate processes that outline data protection, erasure, and hosting into your service-level agreements (SLA). 6. Employee Training and Awareness Programs What’s cloud risk management without training personnel? At the crux of risk management is identifying potential threats and taking steps to prevent them. Insider threats and the human factor contribute significantly to threats today. So, training employees on what to do to prevent risks during and after incidents can make a difference. 7. Adopt an Optimized Cloud Service Model Choose a cloud service model that suits your business, minimizes risks, and optimizes your cloud investment cost. 8. Continuous Improvement and Adaptation to Emerging Threats As a rule of thumb, you should always look to stay ahead of the curve. Conduct regular security assessments and audits to improve cloud security posture and adapt to emerging threats. Skills Needed for Cloud Architects in Risk Management Implementing effective cloud risk management requires having skilled architects on board. Through their in-depth understanding of cloud platforms, services, and technologies, these professionals can help organizations navigate complex cloud environments and design appropriate risk mitigation strategies. Cloud Security Expertise: This involves an understanding of cloud-specific security challenges and a solid knowledge of the cloud provider’s security capabilities. Risk Assessment and Management Skills: Cloud architects must be proficient in risk assessment processes, methodologies, and frameworks. It is also essential to prioritize risks based on their perceived impact and implement appropriate controls. Compliance and Regulatory Knowledge: Not complying with regulatory requirements may cause similar damage as poor risk management. Due to significant legal fees or fines, cloud architects must understand relevant industry regulations and compliance standards. They must also incorporate these requirements into the company’s risk management strategies. Incident Response and Incident Handling: Risk management aims to reduce the likelihood of incidents or their impact. It doesn’t mean completely eradicating incidents. So, when these incidents eventually happen, you want cloud security architects who can respond adequately and implement best practices in cloud environments. Conclusion The importance of prioritizing risk management in cloud environments cannot be overstated. It allows you to proactively identify risks, assess, prioritize, and mitigate them. This enhances the reliability and resilience of your cloud systems, promotes business continuity, optimizes resource utilization, and helps you manage compliance.

Uncategorized How To Prevent Firewall Breaches (The 2024 Guide) Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 1/11/24 Published Properly configured firewalls are vital in any comprehensive cybersecurity strategy. However, even the most robust configurations can be vulnerable to exploitation by attackers. No single security measure can offer absolute protection against all cyber threats and data security risks . To mitigate these risks, it’s crucial to understand how cybercriminals exploit firewall vulnerabilities. The more you know about their tactics, techniques, and procedures, the better-equipped you are to implement security policies that successfully block unauthorized access to network assets. In this guide, you’ll understand the common cyber threats that target enterprise firewall systems with the goal of helping you understand how attackers exploit misconfigurations and human vulnerabilities. Use this information to protect your network from a firewall breach. Understanding 6 Tactics Cybercriminals Use to Breach Firewalls 1. DNS Leaks Your firewall’s primary use is making sure unauthorized users do not gain access to your private network and the sensitive information it contains. But firewall rules can go both ways – preventing sensitive data from leaving the network is just as important. If enterprise security teams neglect to configure their firewalls to inspect outgoing traffic, cybercriminals can intercept this traffic and use it to find gaps in your security systems. DNS traffic is particularly susceptible to this approach because it shows a list of websites users on your network regularly visit. A hacker could use this information to create a spoofed version of a frequently visited website. For example, they might notice your organization’s employees visit a third-party website to attend training webinars. Registering a fake version of the training website and collecting employee login credentials would be simple. If your firewall doesn’t inspect DNS data and confirm connections to new IP addresses, you may never know. DNS leaks may also reveal the IP addresses and endpoint metadata of the device used to make an outgoing connection. This would give cybercriminals the ability to see what kind of hardware your organization’s employees use to connect to external websites. With that information in hand, impersonating managed service providers or other third-party partners is easy. Some DNS leaks even contain timestamp data, telling attackers exactly when users requested access to external web assets. How to protect yourself against DNS leaks Proper firewall configuration is key to preventing DNS-related security incidents. Your organization’s firewalls should provide observability and access control to both incoming and outgoing traffic. Connections to servers known for hosting malware and cybercrime assets should be blocked entirely. Connections to servers without a known reputation should be monitored closely. In a Zero Trust environment , even connections to known servers should benefit from scrutiny using an identity-based security framework. Don’t forget that apps can connect to external resources, too. Consider deploying web application firewalls configured to prevent DNS leaks when connecting to third-party assets and servers. You may also wish to update your security policy to require employees to use VPNs when connecting to external resources. An encrypted VPN connection can prevent DNS information from leaking, making it much harder for cybercriminals to conduct reconnaissance on potential targets using DNS data. 2. Encrypted Injection Attacks Older, simpler firewalls analyze traffic by looking at different kinds of data packet metadata. This provides clear evidence of certain denial-of-service attacks, clear violations of network security policy , and some forms of malware and ransomware . They do not conduct deep packet inspection to identify the kind of content passing through the firewall. This provides cybercriminals with an easy way to bypass firewall rules and intrusion prevention systems – encryption . If malicious content is encrypted before it hits the firewall, it may go unnoticed by simple firewall rules. Only next-generation firewalls capable of handling encrypted data packets can determine whether this kind of traffic is secure or not. Cybercriminals often deliver encrypted injection attacks through email. Phishing emails may trick users into clicking on a malicious link that injects encrypted code into the endpoint device. The script won’t decode and run until after it passes the data security threshold posed by the firewall. After that, it is free to search for personal data, credit card information, and more. Many of these attacks will also bypass antivirus controls that don’t know how to handle encrypted data. Task automation solutions like Windows PowerShell are also susceptible to these kinds of attacks. Even sophisticated detection-based security solutions may fail to recognize encrypted injection attacks if they don’t have the keys necessary to decrypt incoming data. How to protect yourself against encrypted injection attacks Deep packet inspection is one of the most valuable features next-generation firewalls provide to security teams. Industry-leading firewall vendors equip their products with the ability to decrypt and inspect traffic. This allows the firewall to prevent malicious content from entering the network through encrypted traffic, and it can also prevent sensitive encrypted data – like login credentials – from leaving the network. These capabilities are unique to next-generation firewalls and can’t be easily replaced with other solutions. Manufacturers and developers have to equip their firewalls with public-key cryptography capabilities and obtain data from certificate authorities in order to inspect encrypted traffic and do this. 3. Compromised Public Wi-Fi Public Wi-Fi networks are a well-known security threat for individuals and organizations alike. Anyone who logs into a password-protected account on public Wi-Fi at an airport or coffee shop runs the risk of sending their authentication information directly to hackers. Compromised public Wi-Fi also presents a lesser-known threat to security teams at enterprise organizations – it may help hackers breach firewalls. If a remote employee logs into a business account or other asset from a compromised public Wi-Fi connection, hackers can see all the data transmitted through that connection. This may give them the ability to steal account login details or spoof endpoint devices and defeat multi-factor authentication. Even password-protected private Wi-Fi connections can be abused in this way. Some Wi-Fi networks still use outdated WEP and WPA security protocols that have well-known vulnerabilities. Exploiting these weaknesses to take control of a WEP or WPA-protected network is trivial for hackers. The newer WPA2 and WPA3 standards are much more resilient against these kinds of attacks. While public Wi-Fi dangers usually bring remote workers and third-party service vendors to mind, on-premises networks are just as susceptible. Nothing prevents a hacker from gaining access to public Wi-Fi networks in retail stores, receptions, or other areas frequented by customers and employees. How to protect yourself against compromised public Wi-Fi attacks First, you must enforce security policies that only allow Wi-Fi traffic secured by WPA2 and WPA3 protocols. Hardware Wi-Fi routers that do not support these protocols must be replaced. This grants a minimum level of security to protected Wi-Fi networks. Next, all remote connections made over public Wi-Fi networks must be made using a secure VPN. This will encrypt the data that the public Wi-Fi router handles, making it impossible for a hacker to intercept without gaining access to the VPN’s secret decryption key. This doesn’t guarantee your network will be safe from attacks, but it improves your security posture considerably. 4. IoT Infrastructure Attacks Smartwatches, voice-operated speakers, and many automated office products make up the Internet of Things (IoT) segment of your network. Your organization may be using cloud-enriched access control systems, cost-efficient smart heating systems, and much more. Any Wi-Fi-enabled hardware capable of automation can safely be included in this category. However, these devices often fly under the radar of security team’s detection tools, which often focus on user traffic. If hackers compromise one of these devices, they may be able to move laterally through the network until they arrive at a segment that handles sensitive information. This process can take time, which is why many incident response teams do not consider suspicious IoT traffic to be a high-severity issue. IoT endpoints themselves rarely process sensitive data on their own, so it’s easy to overlook potential vulnerabilities and even ignore active attacks as long as the organization’s mission-critical assets aren’t impacted. However, hackers can expand their control over IoT devices and transform them into botnets capable of running denial-of-service attacks. These distributed denial-of-service (DDoS) attacks are much larger and more dangerous, and they are growing in popularity among cybercriminals. Botnet traffic associated with DDoS attacks on IoT networks has increased five-fold over the past year , showing just how promising it is for hackers. How to protect yourself against IoT infrastructure attacks Proper network segmentation is vital for preventing IoT infrastructure attacks . Your organization’s IoT devices should be secured on a network segment that is isolated from the rest of the network. If attackers do compromise the entire network, you should be protected from the risk of losing sensitive data from critical business assets. Ideally, this protection will be enforced with a strong set of firewalls managing the connection between your IoT subnetwork and the rest of your network. You may need to create custom rules that take your unique security risk profile and fleet of internet-connected devices into account. There are very few situations in which one-size-fits-all rulemaking works, and this is not one of them. All IoT devices – no matter how small or insignificant – should be protected by your firewall and other cybersecurity solutions . Never let these devices connect directly to the Internet through an unsecured channel. If they do, they provide attackers with a clear path to circumvent your firewalls and gain access to the rest of your network with ease. 5. Social Engineering and Phishing Social engineering attacks refer to a broad range of deceptive practices used by hackers to gain access to victims’ assets. What makes this approach special is that it does not necessarily depend on technical expertise. Instead of trying to hack your systems, cybercriminals are trying to hack your employees and company policies to carry out their attacks. Email phishing is one of the most common examples. In a typical phishing attack , hackers may spoof an email server to make it look like they are sending emails from a high-level executive in the company you work for. They can then impersonate this executive and demand junior accountants pay fictitious invoices or send sensitive customer data to email accounts controlled by threat actors. Other forms of social engineering can use your organization’s tech support line against itself. Attackers may pretend to represent large customer accounts and will leverage this ruse to gain information about how your company works. They may impersonate a third-party vendor and request confidential information that the vendor would normally have access to. These attacks span the range from simple trickery to elaborate confidence scams. Protecting against them can be incredibly challenging, and your firewall capabilities can make a significant difference in your overall state of readiness. How to protect yourself against social engineering attacks Employee training is the top priority for protecting against social engineering attacks . When employees understand the company’s operating procedures and security policies, it’s much harder for social engineers to trick them. Ideally, training should also include in-depth examples of how phishing attacks work, what they look like, and what steps employees should take when contacted by people they don’t trust. 6. Sandbox Exploits Many organizations use sandbox solutions to prevent file-based malware attacks. Sandboxes work by taking suspicious files and email attachments and opening them in a secure virtual environment before releasing them to users. The sandbox solution will observe how the file behaves and quarantine any file that shows malicious activity. In theory, this provides a powerful layer of defense against file-based attacks. But in practice, cybercriminals are well aware of how to bypass these solutions. For example, many sandbox solutions can’t open files over a certain size. Hackers who attach malicious code to large files can easily get through. Additionally, many forms of malware do not start executing malicious tasks the second they are activated. This delay can provide just enough of a buffer to get through a sandbox system. Some sophisticated forms of malware can even detect when they are being run in a sandbox environment – and will play the part of an innocent program until they are let loose inside the network. How to protect yourself against sandbox exploits Many next-generation firewalls include cloud-enabled sandboxing capable of running programs of arbitrary size for a potentially unlimited amount of time. More sophisticated sandbox solutions go to great lengths to mimic the system specifications of an actual endpoint so malware won’t know it is being run in a virtual environment. Organizations may also be able to overcome the limitations of the sandbox approach using Content Disarm and Reconstruction (CDR) techniques. This approach keeps potentially malicious files off the network entirely and only allows a reconstructed version of the file to enter the network. Since the new file is constructed from scratch, it will not contain any malware that may have been attached to the original file.
