# Policyengine Defensive Response

I designed the PolicyEngine guardrails for GENESIS AI to ensure autonomous defensive actions are safe, auditable, and under human oversight.

Protected Subnet Isolation: Targets residing in RFC 1918 private subnets (`<redacted>/8`, `<redacted>/12`, `<redacted>/16`), loopback (`<redacted>/8`), or RFC 5737 benchmark ranges are flagged as `isProtected=True` and blocked.

Analyst Step‑Up Approval: When a target IP is public, the engine raises a step‑up request; the analyst can respond with “Approved” to proceed or “Rejected” to cancel the action.

One‑Click Rollback: After a defensive playbook runs, the UI provides a “One‑Click Rollback” button that triggers the `ROLLBACK` state and records `ROLLED_BACK` in the action log.

Emergency Defense Halt: A persistent global kill switch (`POST /api/v1/response/emergency-halt`) immediately suspends all autonomous execution.

The defensive action lifecycle follows an explicit state machine: `PENDING → CONFIRMED → EXECUTING → COMPLETED → ROLLED_BACK`.
