What are Pod Security Standards in Kubernetes?

PSS are namespace labels enforcing pod security levels: privileged (wide open), baseline (sane defaults), restricted (locked down, no root).

How do I enforce restricted PSS without downtime?

Label with `warn=restricted` first, audit violations 1-2 weeks, fix pods, switch to `enforce=restricted`. Zero downtime proven.

Does PSS replace tools like OPA Gatekeeper?

No — PSS is built-in basics. Gatekeeper adds customs like image bans or limits.

⚡ Key Takeaways

Enforce PSS 'restricted' on prod namespaces after warn-mode trial to block most escapes. 𝕏
Use baseline for exceptions; don't disable cluster-wide for one app. 𝕏
Layer Gatekeeper, Falco, and CI tools on PSS — it's not enough alone. 𝕏
