This blog post runs you through how to enable and configure Linux audit logging on your Azure Kubernetes Service (AKS) Virtual Machine Scale Set (VMSS) using the Linux auditing subsystem, also known as auditd. Warning The information provided below is accurate as of the release date of this blog post (2023-03) and guidance may change in future.
As more businesses shift away from running workloads on dedicated virtual machines to running them inside containers using workload orchestrators like Kubernetes, adversaries have become more interested in them as targets. Moreover, the benefits Kubernetes provides for managing workloads are also extended to adversaries. As adversaries leverage Kubernetes to run their workloads, their understanding of how these platforms work and can be exploited increases.
At Microsoft, we invest a lot of time researching and investigating possibilities in our journey to memory safety. Because the massive majority of existing codebases are written in unsafe programming languages, the task of protecting legacy code is very important. Hardware solutions are an attractive approach because they introduce very powerful security properties with low overheads compared to purely software solutions.

As Cybersecurity Awareness Month 2022 comes to a close, I’m grateful for the impact it has had in bringing cybersecurity to the forefront since it began in 2004. Though the month may be over, our work in cybersecurity is never done. Often, we think about cybersecurity as a complex technology problem, but at its core, it’s really about people: the customers and communities we work to protect and defend, the current and future cybersecurity professionals on the front lines of the fight, and the larger security community coming together to strengthen cybersecurity for all.
