tomevault-io Security Secrets Management
Overview
Use this skill to prevent secret exposure and ensure secrets remain manageable throughout their lifecycle.
Scope Boundaries
- New secrets are introduced or existing secrets are rotated/migrated.
- Secret storage and runtime distribution mechanisms are being designed.
- Secret exposure response and revocation capability need verification.
Templates And Assets
- Secrets inventory template:
assets/secrets-inventory-template.csv
Inputs To Gather
- Secret inventory by owner, purpose, and environment.
- Storage and access architecture (vault/KMS/secret manager, runtime injection path).
- Rotation cadence, revocation requirements, and dependency constraints.
- Audit and compliance obligations for access and change tracking.
Deliverables
- Secret lifecycle policy covering creation, storage, usage, rotation, and retirement.
- Access control model with least-privilege and break-glass constraints.
- Rotation runbook with rehearsal and rollback guidance.
- Detection and response playbook for secret leakage events.
Workflow
- Build/refresh secret inventory with
assets/secrets-inventory-template.csv. - Enforce non-hardcoded secret policy across source, CI, build artifacts, and logs.
- Choose distribution model (pull, sidecar, env injection, runtime fetch) based on blast radius and operability.
- Define rotation strategy by secret type, including coordinated client update order.
- Implement auditing for secret reads, writes, and policy changes.
- Rehearse emergency rotation and revoke compromised credentials end-to-end.
- Verify decommissioned secrets cannot still authenticate.
Quality Standard
- Every secret has a clear owner and rotation/revocation process.
- Runtime access is identity-bound and minimally scoped.
- Secret exposure can be detected and remediated quickly.
- Audit trails support incident and compliance investigations.
Failure Conditions
- Stop when any production secret is stored in plaintext repositories.
- Stop when rotation cannot be executed without prolonged outage.
- Escalate when secret access is unaudited or broadly shared.
