Osama's Tech Notes - Tetragon

My detailed notes on Tetragon

For IT and security professionals responsible for securing Linux or Kubernetes workloads, Tetragon is a solution well worth exploring. It offers robust capabilities to both monitor and enforce controls over:

• process execution
• network connections and
• file access

in both containerized and non-containerized environments.

In the interest of knowledge sharing, I’m releasing my notes from a recent deep dive I took into Tetragon. The document covers a broad range of topics including:

• a comparison between Tetragon and alternative solutions such as Falco
• limitations I ran into using Tetragon
• performance (exceptionally good due to its design)
• deployment in both Kubernetes and standalone environments
• a look at the different hook point types (kprobes, tracepoints, lsm-bpf, uprobes, and usdts)
• some of the recommended hook points, including relevant LSM functions
• event filtering mechanisms and automated response actions
• leveraging Tetragon for File Integrity Monitoring (FIM) and File Access Runtime Enforcement and finally,
• output options including sanitizing sensitive fields.
