MAS-08Suspend propagation

Suspending an agent under ACT-07 also suspends or quarantines any agent currently depending on it within an active chain. The propagation behavior is documented, tested, and exercised during incident response drills.

A suspend or revoke decision propagates to dependent agents within a documented latency. Suspending an agent under ACT-07 also suspends or quarantines any agent currently depending on it within an active chain. The propagation behavior is documented, tested at least annually, and exercised during incident response drills. This ensures that a compromised agent cannot continue operating through downstream proxies.

(Critical)A Critical failure precludes HI-AAF Certification regardless of the maturity level achieved on any other control.

Table MAS-08.1 · Maturity criteria · v.1.3

L1 to L5 · the lowest level in scope caps the agent
L1Ad hoc

Controls exist informally; documentation is incomplete; no consistent review.

L2Documented

Controls are written down; ownership is assigned; review cadence is defined.

L3Operated

Controls are followed in practice; evidence is collected; deviations are tracked.

Suspend propagation is implemented and documented; propagation has been tested in a drill or live incident within the documented cadence; propagation latency is measured and within SLA; dependent agents enter suspend state within the documented latency.

L4Measured

Control effectiveness is measured against documented thresholds; trends are reported.

L5Continuously Improved

Controls evolve based on incident learning; maturity gains are evidenced over time.

The v1.3 edition publishes a control-specific criterion at L3 (Operated). The other levels apply the general ladder to this control; see the maturity ladder.

Evidence an assessor asks for

  1. E.1

    Suspend propagation is implemented and documented.

  2. E.2

    Propagation has been tested in a drill or live incident within the documented cadence.

  3. E.3

    Propagation latency is measured and within SLA.

  4. E.4

    Dependent agents enter suspend state within the documented latency.

Mappings are directional: meeting this control evidences but does not by itself satisfy the external requirement. A middle dot means no control-level reference is published at this edition; see the crosswalk.
