Add a managerial security frame on top of the host baseline: explicit threat model (opportunistic external, lateral movement/blast radius, operator/agent error; supply chain accepted-lower-priority), security principles, and four governance mechanisms that ADR-002 establishes and links out to: - docs/security/service-checklist.md — per-service security bar (referenced from the new-role runbook) - docs/security/accepted-risks.md — living accepted-risk register (R1-R4) - planned /security-review skill (TODO 8.5) - agent guardrails in CLAUDE.md "what Claude must not do" STATUS.md records the frame as present (manual enforcement) and /security-review as planned-not-built.

# Per-service security checklist
|
|
|
|
The bar every service (a per-service role — ADR-004) must clear **before deploy**,
|
|
especially anything reachable beyond its own host. Established by **ADR-002**
|
|
(Security baseline and strategy); referenced from `docs/runbooks/new-role.md`.
|
|
Enforced manually in review today; the planned `/security-review` skill (see
|
|
`docs/TODO.md`) will automate the check.
|
|
|
|
Treat each item as must-pass **unless** a deviation is recorded in
|
|
`docs/security/accepted-risks.md` with a rationale and a revisit trigger.
|
|
|
|
## Secrets & credentials
|
|
|
|
- [ ] All secrets live in an encrypted `vault.yml` (`vault.<service>.<key>`); none in
|
|
plaintext files, templates, or Compose env literals
|
|
- [ ] No default or vendor-shipped credentials remain — admin passwords/tokens are
|
|
generated and stored in vault
|
|
- [ ] Nothing secret is baked into an image or committed to git (gitleaks must pass)
|
|
|
|
## Least privilege
|
|
|
|
- [ ] Container runs as a non-root user where the image supports it
|
|
- [ ] No `privileged: true` and no host network mode unless explicitly justified
|
|
- [ ] Only the volumes/paths the service needs are mounted; read-only where possible
|
|
- [ ] Linux capabilities dropped to what's required (no blanket grants)
|
|
|
|
## Network & exposure
|
|
|
|
- [ ] Every listening port is declared in `group_vars` firewall definitions — never
|
|
opened ad-hoc on a host
|
|
- [ ] The service is not published directly to a LAN/WAN port if it can sit behind the
|
|
reverse proxy instead
|
|
- [ ] Anything reachable beyond the `srv` VLAN is behind the reverse proxy **with
|
|
authentication** (and TLS)
|
|
- [ ] Inter-service reach follows least privilege — no broad `srv`→`srv` access where a
|
|
single declared dependency suffices
|
|
|
|
## Updates & provenance
|
|
|
|
- [ ] Image/source version is pinned (tag or digest), not floating `latest` (ADR-011)
|
|
- [ ] The update path is known — how this service gets patched
|
|
|
|
## Operability (security-adjacent)
|
|
|
|
- [ ] Logs go somewhere reviewable (central aggregation when available)
|
|
- [ ] Backup/restore is covered if the service holds state
|
