planifest Kubernetes Security
Overview
Use this skill to implement enforceable Kubernetes security controls that reduce blast radius and privilege misuse.
Scope Boundaries
- Use this skill when the task matches the trigger condition described in
description. - Do not use this skill when the primary task falls outside this skill's domain.
Shared References
- RBAC and NetworkPolicy baselines:
references/rbac-networkpolicy-baselines.md
Templates And Assets
- Security control matrix:
assets/security-control-matrix-template.csv
- Pod security checklist:
assets/pod-security-checklist.md
Inputs To Gather
- Workload trust boundaries and risk profile.
- Access requirements by service account/namespace.
- East-west network communication requirements.
- Secret lifecycle and policy constraints.
Deliverables
- Kubernetes security control matrix with ownership.
- Pod-level hardening decisions.
- RBAC and network isolation policy definitions.
- Verification evidence for applied controls.
Workflow
- Build control matrix in
assets/security-control-matrix-template.csv. - Define RBAC and network policy using
references/rbac-networkpolicy-baselines.md. - Validate workload hardening with
assets/pod-security-checklist.md. - Verify secret and policy enforcement behavior.
- Publish accepted risks and remediation backlog.
Quality Standard
- Access controls follow least-privilege principles.
- Network paths are explicit and deny-by-default where feasible.
- Pod security posture is consistent and reviewable.
- Secret handling minimizes exposure in runtime and config.
Failure Conditions
- Stop when critical workloads run without required isolation controls.
- Stop when privilege model cannot be audited from manifests/policies.
- Escalate when required controls conflict with runtime constraints.
