# Tamper-resistant credential governance + mass rotation/lockdown (Strand B)
|
|
|
|
## Origin
|
|
|
|
Explicitly deferred from `WARDEN-WP-0026` (credential disclosure hygiene, Strand A).
|
|
WP-0026 "Out of scope" carves out the heavyweight governance machinery and directs
|
|
that it be "capture[d] separately if/when justified." This workplan is that capture.
|
|
|
|
Strand A makes accidental disclosure structurally hard and gives every lane
|
|
**advisory** rotation guidance. Strand B is the **executable, tamper-resistant**
|
|
layer: turning that advisory guidance into one-command action and hardening policy
|
|
governance against silent drift or malicious change.
|
|
|
|
## Status: backlog (captured, not scheduled)
|
|
|
|
This is deliberately **not `ready`**. It carries real cost and blast radius
|
|
(break-glass re-key, trust-root design) that is not justified until Strand A is in
|
|
production and a concrete trigger appears. See **Activation gate** below. Nothing
|
|
here is implemented until the gate is met and Bernd promotes it to `ready`.
|
|
|
|
## Activation gate (promote to `ready` only when ≥1 holds)
|
|
|
|
- A real disclosure incident requires rotating **more than a couple** of secrets at
|
|
once, making manual per-lane rotation (Strand A) too slow.
|
|
- Fleet policy for OpenBao mandates tamper-evident policy governance or a designed
|
|
break-glass path.
|
|
- Audit/compliance requires provable "reconcile policy to a known-good commit."
|
|
|
|
## Goal
|
|
|
|
Make credential response **executable and trustworthy at fleet scale**: one command
|
|
rotates or re-establishes a set of tainted secrets; policy changes are tamper-evident
|
|
and reconcilable to a known-good state; a graded lockdown / break-glass path exists
|
|
with an explicit trust-root.
|
|
|
|
## Scope boundary (unchanged from Strand A)
|
|
|
|
ops-warden still **custodies no secret values**. Strand B orchestrates the owner's
|
|
tools (OpenBao, provider re-mint, railiance-platform credential broker) as the
|
|
caller — it does not hold or vend secrets. Rotation execution runs the owner-native
|
|
path; ops-warden sequences and verifies it.
|
|
|
|
## Task: Executable mass rotation driver
|
|
|
|
```task
|
|
id: WARDEN-WP-0027-T01
|
|
status: wait
|
|
priority: high
|
|
state_hub_task_id: "604aad14-d398-4c02-85e5-7ff37a905a1b"
|
|
```
|
|
|
|
Turn Strand A's per-lane `rotation:` guidance (WP-0026 T06) into an executable
|
|
driver: `warden rotate <id>` (single lane) and `warden rotate --tainted` (all lanes
|
|
marked EXPOSED per WP-0026 T05). Each step runs the owner-native command
|
|
(provider re-mint, `bao kv put`, re-encrypt+reupload for re-establish lanes) as the
|
|
caller, verifies via capabilities (never reads the value), and clears the
|
|
`exposed_at` taint on success. Dry-run first; idempotent; per-lane failure isolates.
|
|
|
|
**Done when:** a tainted set of lanes can be rotated/re-established with one command,
|
|
each verified capabilities-safe, taint cleared only on success.
|
|
|
|
**Depends on:** WP-0026 T05 (taint convention), T06 (rotation registry).
|
|
|
|
## Task: Graded lockdown / break-glass with explicit trust-root
|
|
|
|
```task
|
|
id: WARDEN-WP-0027-T02
|
|
status: wait
|
|
priority: medium
|
|
state_hub_task_id: "9d004d8f-6215-4178-bd13-5785d24fd152"
|
|
```
|
|
|
|
Design and document a graded lockdown: (a) soft — deny agent roles read on all
|
|
high-risk lanes; (b) hard — seal + re-key with a pre-designed trust-root and quorum.
|
|
Define the trust-root (who holds unseal shares, recovery keys), the break-glass
|
|
invocation, and the re-entry path. **Design + runbook first**; any executable seal
|
|
step is opt-in and attended.
|
|
|
|
**Done when:** a documented, rehearsed break-glass path exists with a named
|
|
trust-root and quorum, and soft-lockdown is executable via capabilities-based
|
|
policy toggles.
|
|
|
|
## Task: Tamper-evident policy governance + reconcile
|
|
|
|
```task
|
|
id: WARDEN-WP-0027-T03
|
|
status: wait
|
|
priority: medium
|
|
state_hub_task_id: "94d5dcaf-abf0-417c-a6ef-26e8c50905a8"
|
|
```
|
|
|
|
Policy-as-code for OpenBao policies/roles with tamper-evidence: a signed/hashed
|
|
manifest of the intended policy set, drift **detection** against live OpenBao, and a
|
|
reconcile-to-known-good-commit path. (Drift detection may land independently even if
|
|
full reconcile stays gated.) Coordinate ownership with railiance-platform (OpenBao
|
|
deployment) — ops-warden contributes the ops-access policy surface, not the cluster.
|
|
|
|
**Done when:** live OpenBao policy state is diffable against a signed known-good
|
|
manifest, and an attended reconcile can restore it.
|
|
|
|
**Cross-repo:** railiance-platform (OpenBao cluster + policy custody).
