Security

Security is governance under constraints. The goal is stable trust boundaries, not performative controls that operators bypass under pressure.

Trust boundaries, not slogans

Kubernetes security fails when it becomes ceremonial without enforcement, or enforcement without operational escape hatches.

Kubblai doctrine is explicit: define least privilege, define break-glass, audit bypass, and treat admission as part of availability.

RBAC determines who can act; admission determines whether actions are permitted.
Secrets require lifecycle posture: creation, distribution, rotation, invalidation.
NetworkPolicy creates containment; without it, namespaces are organizational, not isolating.
