Being able to understand the impact of the available security options, especially when it comes to configuring our deployments, is one of the key aspects to make the default security in Kubernetes stronger. We have all those logging, tracing and metrics data already at hand, but how do we assemble the information they provide into something human readable and actionable?
Seccomp is one of the standard mechanisms to protect a Linux based Kubernetes application from malicious actions by interfering with its system calls. This allows us to restrict the application to a defined set of actionable items, like modifying files or responding to HTTP requests. Linking the knowledge of which set of syscalls is required to, for example, modify a local file, to the actual source code is in the same way non-trivial.
