What it detects
This rule detects Kubernetes API server requests authenticated as the anonymous or unauthenticated system identity which indicates an unauthenticated actor probing the cluster control plane as described in NCC Group Kubernetes detection engineering research. Adversaries leverage anonymous access to enumerate resources and stage container escapes so any such request warrants investigation.
