Cyber Attacks & Incident Response How to improve network security (7 fundamental ways) 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 As per Cloudwards , a new organization gets hit by ransomware every 14 seconds. This is despite the fact that global cybersecurity spending is up and is around $150 billion per year. That’s why fortifying your organization’s network security is the need of the hour. Learn how companies are proactively improving their network security with these best practices. 7 Ways to improve network security: ` 1. Change the way you measure cyber security risk Cyber threats have evolved with modern cybersecurity measures. Thus, legacy techniques to protect the network are not going to work. These techniques include measures like maturity assessment, compliance attestation, and vulnerability aging reports, among other things. While they still have a place in cybersecurity, they’re insufficient. To level up, you need greater visibility over the various risk levels. This visibility will allow you to deploy resources as per need. At the bare minimum, companies need a dashboard that lists real-time data on the number of applications, the region they’re used in, the size and nature of the database, the velocity of M&A, etc. IT teams can make better decisions since the impact of new technologies like big data and AI falls unevenly on organizations. Along with visibility, companies need transparency and precision on how the tools behave against cyberattacks. You can use the ATT&CK Framework developed by MITRE Corporation, the most trustworthy threat behavior knowledge base available today. Use it as a benchmark to test the tools’ efficiency. Measuring the tools this way helps you prepare well in advance. Another measurement technique you must adopt is measuring performance against low-probability, high-consequence attacks. Pick the events that you conclude have the least chance of occurring. Then, test the tools on such attacks. Maersk learned this the hard way. In the notPetya incident , the company came pretty close to losing all of its IT data. Imagine the consequence it’d have on the company that handles the world’s supply chain. Measuring is the only way to learn whether your current cybersecurity arrangements meet the need. 2. Use VLAN and subnets An old saying goes, ‘Don’t keep all your eggs in the same basket.’ Doing so would mean losing the basket, losing all your eggs. That is true for IT networks as well. Instead of treating your network as a whole, divide it into multiple subnetworks. There are various ways you can do that: VLAN or Virtual LAN is one of them. VLAN helps you segment a physical network without investing in additional servers or devices. The different segments can then be handled differently as per the need. For example, the accounting department will have a separate segment, and so will the marketing and sales departments. This segmentation helps enhance security and limit damage. VLAN also helps you prioritize data, networks, and devices. There will be some data that is more critical than others. The more critical data warrant better security and protection, which you can provide through a VLAN partition. Subnets are another way to segment networks. As opposed to VLAN, which separates the network at the switch level, subnets partition the network at IP level or level 3. The various subnetworks can then communicate with each other and third-party networks over IP. With the adoption of technologies like the Internet of Things (IoT), network segmentation is only going to get more critical. Each device used for data generation, like smartwatches, sensors, and cameras, can act as an entry point to your network. If the entry points are connected to sensitive data like consumers’ credit cards, it’s a recipe for disaster. You can implement VLAN or subnets in such a scenario. 3. Use NGFWs for cloud The firewall policy is at the core of cybersecurity. They’re essentially the guardians who check for intruders before letting the traffic inside the network. But with the growth of cloud technologies and the critical data they hold, traditional firewalls are no longer reliable. They can easily be passed by modern malware. You must install NGFWs or Next Generation Firewalls in your cloud to ensure total protection. These firewalls are designed specifically to counter modern cyberattacks. An NGFW builds on the capabilities of a traditional firewall. Thus, it inspects all the incoming traffic. But in addition, it has advanced capabilities like IPS (intrusion prevention system), NAT (network address translation), SPI (stateful protocol inspection), threat intelligence feeds, container protection, and SSL decryption, among others. NGFWs are also both user and application-aware. This allows them to provide context on the incoming traffic. NGFWs are important not only for cloud networks but also for hybrid networks . Malware from the cloud could easily transition into physical servers, posing a threat to the entire network. When selecting a next-gen firewall for your cloud, consider the following security features: The speed at which the firewall detects threats. Ideally, it should identify the attacks in seconds and detect data breaches within minutes. The number of deployment options available. The NGFW should be deployable on any premise, be it a physical, cloud, or virtual environment. Also, it should support different throughput speeds. The home network visibility it offers. It should report on the applications and websites, location, and users. In addition, it should show threats across the separate network in real-time. The detection capabilities. It goes without saying, but the next-gen firewall management should detect novel malware quickly and act as an anti-virus. Other functionalities that are core security requirements. Every business is different with its unique set of needs. The NGFW should fulfill all the needs. 4. Review and keep IAM updated To a great extent, who can access what determines the security level of a network. As a best practice, you should grant access to users as per their roles and requirement — nothing less, nothing more. In addition, it’s necessary to keep IAM updated as the role of users evolves. IAM is a cloud service that controls unauthorized access for users. The policies defined in this service either grant or reject resource access. You need to make sure the policies are robust. This requires you to review your IT infrastructure, the posture, and the users at the organization. Then create IAM policies and grant access as per the requirement. As already mentioned, users should have remote access to the resources they need. Take that as a rule. Along with that, uphold these important IAM principles to improve access control and overall network security strategy: Zero in on the identity It’s important to identify and verify the identity of every user trying to access the network. You can do that by centralizing security control on both user and service IDs. Adopt zero-trust Trust no one. That should be the motto when handling a company’s network security. It’s a good practice to assume every user is untrustworthy unless proven otherwise. Therefore, have a bare minimum verification process for everyone. Use MFA MFA or multi-factor authentication is another way to safeguard network security. This could mean they have to provide their mobile number or OTA pin in addition to the password. MFA can help you verify the user and add an additional security layer. Beef up password Passwords are a double-edged sword. They protect the network but also pose a threat when cracked. To prevent this, choose strong passwords meeting a certain strength level. Also, force users to update their unique passwords regularly. If possible, you can also go passwordless. This involves installing email-based or biometric login systems. Limit privileged accounts Privileged accounts are those accounts that have special capabilities to access the network. It’s important to review such accounts and limit their number. 5. Always stay in compliance Compliance is not only for pleasing the regulators. It’s also for improving your network security. Thus, do not take compliance for granted; always make your network compliant with the latest standards. Compliance requirements are conceptualized after consulting with industry experts and practitioners. They have a much better authoritative position to discuss what needs to be done at an industry level. For example, in the card sector, it’s compulsory to have continuous penetration testing done. So, when fulfilling a requirement, you adopt the best practices and security measures. The requirements don’t remain static. They evolve and change as loopholes emerge. The new set of compliance frameworks helps ensure you’re up-to-date with the latest standards. Compliance is also one of the hardest challenges to tackle. That’s because there are various types of compliances. There are government-, industry-, and product-level compliance requirements that companies must keep up with. Moreover, with hybrid networks and multi-cloud workflows, the task only gets steeper. Cloud security management tools can help in this regard to some extent. Since they grant a high level of visibility, spotting non-compliance becomes easier. Despite the challenges, investing more is always wise to stay compliant. After all, your business reputation depends on it. 6. Physically protect your network You can have the best software or service provider to protect your wireless networks and access points. But they will still be vulnerable if physical protection isn’t in place. In the cybersecurity space, the legend has it that the most secure network is the one that’s behind a closed door. Any network that has humans nearby is susceptible to cyberattacks. Therefore, make sure you have appropriate security personnel at your premises. They should have the capability and authority to physically grant or deny access to those seeking access to the network on all operating systems. Make use of biometric IDs to identify the employees. Also, prohibit the use of laptops, USB drives, and other electronic gadgets that are not authorized. When creating a network, data security teams usually authorize each device that can access it. This is known as Layer 1. To improve network security policy , especially on Wi-Fi (WPA), ensure all the network devices and workstations and SSIDs connected to the network as trustworthy. Adopt the zero-trust security policies for every device: considered untrustworthy until proven otherwise. 7. Train and educate your employees Lastly, to improve network security management , small businesses must educate their employees and invest in network monitoring. Since every employee is connected to the Wi-Fi network somehow, everyone poses a security threat. Hackers often target those with privileged access. Such accounts, once exploited by cybercriminals, can be used to access different segments of the network with ease. Thus, such personnel should receive education on priority. Train your employees on attacks like phishing, spoofing, code injection, DNS tunneling, etc. With knowledge, employees can tackle such attempts head-on. This, in turn, makes the network much more secure. After the privileged account holders are trained, make others in your organization undergo the same training. The more educated they are, the better it is for the network. It’s worth reviewing their knowledge of cybersecurity from time to time. You can conduct a simple survey in Q&A format to test the competency of your team. Based on the results, you can hold training sessions and get everyone on the same page. The bottom line on network security Data breaches often come at a hefty cost. And the most expensive item on the list is the trust of users. Once a data leak happens, retaining customers’ trust is very hard. Regulators aren’t easy on the executives either. Thus, the best option is to safeguard and improve your network security .

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

Firewall Change Management Firewall performance tuning: Common issues & resolutions 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 8/9/23 Published A firewall that runs 24/7 requires a good amount of computing resources. Especially if you are running a complex firewall system, your performance overhead can actually slow down the overall throughput of your systems and even affect the actual functionalities of your firewall. Here is a brief overview of common firewall performance issues and the best practices to help you tune your firewall performance . 7 Common performance issues with firewalls Since firewall implementations often include some networking hardware usage, they can slow down network performance and traffic bottlenecks within your network. 1. High CPU usage The more network traffic you deal with, the more CPU time your server will need. When a firewall is running, it adds to CPU utilization since the processes need more power to execute the network packet analysis and subsequent firewall This may lead to firewall failures in extreme cases where the firewall process is completely shut down or the system experiences a noticeable lag affecting overall functionality. A simple way to resolve this issue would be to increase the hardware capabilities. But as that might not be a viable solution in all cases, you must consider minimizing the network traffic with router-level filtering or decreasing the server load with optimized 2. Route flapping Router misconfiguration or hardware failure can cause frequent advertising of alternate routes. This will increase the load on your resources and thus lead to performance issues. 3. Network errors and discards A high number of error packets or discarded packets can burden your resources as these packets are still processed by the firewall even when they ultimately turn out to be dud in terms of traffic. Such errors usually happen when routers try to reclaim some buffer space. 4. Congested network access link Network access link congestion can be caused due to a bottleneck happening between a high bandwidth IP Network and LAN. When there is high traffic, the router queue gets filled and causes jitters and time delays. When there are more occurrences of jitter, more packets are dropped on the receiving end, causing a degradation of the quality of audio or video being transmitted. This issue is often observed in VoIP systems . 5. Network link failure When packet loss continues for over a few seconds, it can be deemed a network link failure. While re-establishing the link could take just a few seconds, the routers may already be looking for alternate routes. Frequent network link failures can be a symptom of power supply or hardware issues. 6. Misconfigurations Software or hardware misconfigurations can easily lead to overloading of LAN, and such a burden can easily affect the system’s performance. Situations like these can be caused by misconfigured multicast traffic and can affect the overall data transfer rate of all users. 7. Loss of packets Loss of packets can cause timeout errors, retransmissions, and network slowness. Loss of packets can happen due to delayed operations, server slowdown, misconfiguration, and several other reasons. How to fine-Tune your firewall performance Firewall performance issues can be alleviated with hardware upgrades. But as you scale up, upgrading hardware at an increasing scale would mean high expenses and an overall inefficient system. A much better cost-effective way to resolve firewall performance issues would be to figure out the root cause and make the necessary updates and fixes to resolve the issues. Before troubleshooting, you should know the different types of firewall optimization techniques: Hardware updates Firewall optimization can be easily achieved through real-time hardware updates and upgrades. This is a straightforward method where you add more capacity to your computing resources to handle the processing load of running a firewall. General best practices This involves the commonly used universal best practices that ensure optimized firewall configurations and working. Security policies, data standard compliances , and keeping your systems up to date and patched will all come under this category of optimizations. Any optimization effort generally applied to all firewalls can be classified under this type. Vendor specific Optimization techniques designed specifically to fit the requirements of a particular vendor are called vendor-specific optimizations. This calls for a good understanding of your protected systems, how traffic flows, and how to minimize the network load. Model specific Similar to vendor-specific optimizations, model-specific optimization techniques consider the particular network model you use. For instance, the Cisco network models usually have debugging features that can slow down performance. Similarly, the PIX 6.3 model uses TCP intercept that can slow down performance. Based on your usage and requirements, you can turn the specific features on or off to boost your firewall performance. Best practices to resolve the usual firewall performance bottlenecks Here are some proven best practices to improve your firewall’s performance. Additionally, you might also want to read Max Power by Timothy Hall for a wholesome understanding. Standardize your network traffic Any good practice starts with rectifying your internal errors and vulnerabilities. Ensure all your outgoing traffic aligns with your cybersecurity standards and regulations. Weed out any application or server sending out requests that don’t comply with the security regulations and make the necessary updates to streamline your network. Router level filtering To reduce the load on your firewall applications and hardware, you can use router-level network traffic filtering. This can be achieved by making a Standard Access List filter from the previously dropped requests and then routing them using this list for any other subsequent request attempts. This process can be time-consuming but is simple and effective in avoiding bottlenecks. Avoid using complicated firewall rules Complex firewall rules can be resource heavy and place a lot of burden on your firewall performance. Simplifying this ruleset can boost your performance to a great extent. You should also regularly audit these rules and remove unused rules. To help you clean up firewall rules, you can start with Algosec’s firewall rule cleanup and performance optimization tool . Test your firewall Regular testing and auditing of your firewall can help you identify any probable causes for performance slowdown. You can collect information on your network traffic and use it to optimize how your firewall operates. You can use Algosec’s firewall auditor services to take care of all your auditing requirements and ensure compliance at all levels. Make use of common network troubleshooting tools To analyze the network traffic and troubleshoot your performance issues, you can use common network tools like netstat and iproute2. These tools provide you with network stats and in-depth information about your traffic that can be well utilized to improve your firewall configurations. You can also use check point servers and tools like SecureXL, and CoreXL. Follow a well-defined security policy As with any security implementation, you should always have a well-defined security policy before configuring your firewalls. This gives you a good idea of how your firewall configurations are made and lets you simplify them easily. Change management is also essential to your firewall policy management process . You should also document all the changes, reviews, and updates you make to your security policies to trace any problematic configurations and keep your systems updated against evolving cyber threats. A good way to mitigate security policy risks is to utilize AlgoSec. Network segmentation Segmentation can help boost performance as it helps isolate network issues and optimize bandwidth allocation. It can also help to reduce the traffic and thus further improve the performance. Here is a guide on network segmentation you can check out. Automation Make use of automation to update your firewall settings. Automating the firewall setup process can greatly reduce setup errors and help you make the process more efficient and less time-consuming. You can also extend the automation to configure routers and switches. Algobot is an intelligent chatbot that can effortlessly handle network security policy management tasks for you. Handle broadcast traffic efficiently You can create optimized rules to handle broadcast traffic without logging to improve performance. Make use of optimized algorithms Some firewalls, such as the Cisco Pix, ASA 7.0 , Juniper network models, and FWSM 4.0 are designed to match packets without dependency on rule order. You can use these firewalls; if not, you will have to consider the rule order to boost the performance. To improve performance, you should place the most commonly used policy rules on the top of the rule base. The SANS Institute recommends the following order of rules: Anti-spoofing filters User permit rules Management permit rules Noise drops Deny and alert Deny and log DNS objects Try to avoid using DNS objects that need DNS lookup services. This slows down the firewall. Router interface design Matching the router interface with your firewall interface is a good way to ensure good performance. If your router interface is half duplex and the firewall is full duplex, the mismatch can cause some performance issues. Similarly, you should try to match the switch interface with your firewall interface, making them report on the same speed and mode. For gigabit switches, you should set up your firewall to automatically adjust speed and duplex mode. You can replace the cables and patch panel ports if you cannot match the interfaces. VPN If you are using VPN and firewalls, you can separate them to remove some VPN traffic and processing load from the firewall and thus increase the performance. UTM features You can remove the additional UTM features like Antivirus, and URL scanning features from the firewall to make it more efficient. This does not mean you completely eliminate any additional security features. Instead, just offload them from the firewall to make the firewall work faster and take up fewer computing resources. Keep your systems patched and updated Always keep your systems, firmware, software, and third-party applications updated and patched to deal with all known vulnerabilities.

Tags Share this article 11/27/20 Published With the rapid proliferation of cloud computing, lean deployment methods, such as containers, have become common practice. According to CIO.com, 70% of global companies are expected to be running multiple apps simultaneously using a containerized framework, like Kubernetes in the next few years. But as Kubernetes’ use becomes more widespread, so do the vulnerabilities inherent to containerization. According to a 2019 Forbes article , Kubernetes had at least 7,000 identified vulnerabilities at the beginning of 2019 alone. Couple that with the fact that cyber-attacks involving containerization have increased a whopping 240% since 2018, and you’ll understand the value of security should your company use a solution like Kubernetes to handle its container orchestration. What Causes Kubernetes Security Blindspots? To understand how to best optimize your Kubernetes experience, it’s worthwhile to understand the basic ways security issues arise in a containerized framework. Images are the core building blocks of containerization; they are the executable process at the centre of your container. As a result, anything that exposes an image to a broader audience puts the container at risk of being hijacked. One of the primary ways this occurs is by using out-of-date software. Using old software gives malicious actors a small incongruence that they can exploit within the code. Another problem is poorly defined user access roles. If sensible changes aren’t made to an orchestration tool’s default settings, inappropriate parties may have access to alter the container’s core executable. Containerization gives you a way to manage a large number of processes easily and with increased adaptability. As a result, automation makes it impossible to keep your eyes on everything at once. Here are some best practices that can help you counter the wide range of vulnerabilities inherent to containerization and Kubernetes in general. Kubernetes Security Best Practices Given the architecture of the Kubernetes framework, security risks are a constant and evolving threat. Luckily, Google made Kubernetes an open-source application under the auspices of the Cloud Native Computing Foundation where solutions to new security issues are actively crowdsourced by the community. Regardless, there are a number of things that you can do during the build, deployment, and runtime phases to make your Kubernetes implementation more secure. Take care of your images Images are the heart of every container. Executable functions are essential, so images must be well-maintained and in good working order. Only use up-to-date images, scanning them regularly for security issues. As a rule of thumb, you should also avoid including unnecessary tools and functions in your image coding as they can inadvertently give hackers an access route. Ensure that your secrets remain secret The term “secrets” refers to any private information such as login credentials, tokens, or other sensitive data. While it’s not customary to keep sensitive data stored adjacent to the container’s image, the scenario has come up before. Keep secret data as far from the image as possible in order to increase security. Keep up-to-date with scans and security patches The community does a good job of patching Kubernetes when issues arise. If you don’t take the time to update both your OS and Kubernetes’ security, you give malware additional avenues of attack. Updates should be performed at least every nine months, if not more often. Due to the nature of how Kubernetes works, if you are using an outdated version, you could actively be spreading issues when the container is deployed elsewhere. Take advantage of customization to define user roles and access A container orchestration tool like Kubernetes is a complex web running thousands of processes across numerous machines. That means hundreds of end-users involved with the application. Take advantage of Kubernetes administrative functions to clearly define user roles, limiting full access for those who don’t need it. As they say, too many cooks spoil the broth. Keeping Kubernetes Simple and Safe Containers are an agile, lightweight framework for cloud computing, but manually deploying the correct containers to their destinations can quickly become overwhelming. An orchestration tool like Kubernetes is the perfect solution to managing your containerization, but the security risks inherent to this model can be restrictive. By keeping a few key practices in mind when implementing Kubernetes into your workflow, you can help to promote safety while streamlining your processes. To Sum It All Up Kubernetes has become the centrepiece of the cloud Native landscape and a notable advantage for organizations to rapidly manage and deploy their containerized business logic. But certain security best practices must be followed such as working with reliable docker images, properly defined resource quotas, network policies, work with namespaces for access control and authentication\authorization, and more.
