With the rapid pace of technological evolution, ensuring security within the systems we operate and the software we deploy has never been more crucial. In the world of vulnerability management, we’ve moved from scanning Linux hosts to scrutinizing container images. However, are we looking for vulnerabilities in the right places?

In the era of cloud computing, Kubernetes has emerged as a true cornerstone of cloud-native technologies. It’s an orchestration powerhouse for application containers, automating their deployment, scaling, and operations across multiple clusters. Kubernetes isn’t just a buzzword; it’s a paradigm shift that underpins the scalability and agility of modern software.

There are things in the world that are absolute, and there are things that are relative. For example, it is an absolute truth that the middle three Star Wars episodes were better than the prequel three. But if we are talking about security, it is mostly accepted to be relative as it is a well-accepted thesis that there is no absolute security. Every system can eventually be broken. Like in the joke about the two folks who are attacked by a lion.

We’re thrilled to introduce a fresh ARMO app designed exclusively for Slack, delivering notifications directly to the channels where your teams focus on tackling security concerns related to Misconfiguration, Vulnerabilities, and Compliance. This integration ensures that your DevSecOps teams receive timely notifications within their preferred collaboration platform, empowering them to take immediate action.

This is not a beginner’s blog post. As such, we will not tell you about the importance of securing your Kubernetes infrastructure (it’s important). However, if you are here to learn about increasing the efficiency of your security work and the blind spots you may have, you have come to the right place. You may have heard of and are already using CVSS as your gold standard for vulnerability prioritization.

Transparency in vulnerability disclosure plays a crucial role in effective risk management, regardless of software development models. The Common Vulnerabilities and Exposures (CVE) database serves as a valuable resource, offering insights into known weaknesses even when fixes are unavailable. This empowers organizations to make informed decisions about prioritizing mitigation strategies and protecting their systems.

In the rapidly evolving world of container orchestration, developers have come to rely on Kubernetes to manage containerized applications. However, as Kubernetes adoption increases among organizations, ensuring the security of Kubernetes environments becomes essential. One particularly significant aspect to consider is vulnerability prioritization. It’s essential to understand that chasing after the highest CVSS scoring vulnerabilities might not always align with real-world threats.

Addressing Common Vulnerabilities and Exposures, known as CVE patching, is a practice of applying updates to software (patching) to address security vulnerabilities. CVE patching is your shield against the threat of malicious actors exploiting such weaknesses and is of crucial importance for every organization’s cybersecurity. This post will cover the basics of CVE patching: the roles and stakeholders, the step-by-step process, and common mistakes to avoid.
