Kubernetes Security Best Practices for 2024

The dynamic Kubernetes security landscape has given rise to several trends shaping how organizations approach this increasingly critical area. The aim of Kubernetes security is to prevent unauthorized access, foster data privacy, and protect the integrity of a Kubernetes environment. Robust Kubernetes security requires a defense-in-depth approach, including measures such as access control, network policies, resource isolation, and security context. Let's explore best practices you can implement to secure your Kubernetes clusters and the workloads and data running within them in 2024.

Are You Looking for Linux Vulnerabilities in the Right Places?

Scanning for vulnerabilities in the right places is critically important in securing your Linux environment. While vulnerability scanning initially involved scanning Linux hosts, it has since shifted to scrutinizing container images. However, in the world of vulnerability management, we often focus on scanning images in registries and CI/CD processes but forget to monitor vulnerabilities where it really matters: container images that are actually running.

What Is eBPF? The Ultimate Guide

eBPF stands for extended Berkeley Packet Filters, which are a way of running programs on network interfaces. There are two types of BPF: classic and extended. Classic BPFs were introduced in Linux 2.6.25, while extended BPFs were introduced with Linux 4.0 (2010), allowing for more functionality than classic BPFs.
