Kubernetes Admission Control & Runtime Hardening

A single misconfigured container — privileged mode, a writable root filesystem, a hostPath mount — can undo every baseline hardened around it. Most of these ship by default, not by decision.

Policy-as-Code Admission

Block at deploy time

Enforces policy at the Kubernetes admission layer, rejecting non-compliant workloads before they're ever scheduled.

Runtime Hardening Defaults

Least-privilege containers

Applies read-only filesystems, dropped capabilities, and seccomp profiles by default, not as an opt-in developers forget.

Supply-Chain Gate

Signed-image enforcement

Refuses to run any image that isn't signed and traceable back to an approved build, closing the gap between CI and runtime.

Runtime Drift Alerting

Post-deploy behavior watch

Flags a running container the moment its behavior diverges from its declared policy, instead of trusting the admission check forever.
