Problem
ir-playbook tells responders to use out-of-band communications during severe incidents, but it does not require evidence that the communication channel itself was assessed, switched, access-controlled, preserved, and later restored safely.
That leaves an operational gap during SEV-1/SEV-2 incidents: responders may coordinate over corporate email, Slack/Teams, ticketing, or endpoint-management channels that the attacker can monitor, while containment orders and stakeholder notifications lack a reliable record of who approved what and through which trusted channel.
Proposed improvement
Add a focused communication channel integrity gate to the IR preparation workflow that requires responders to capture:
- Channel trust status for email, chat, ticketing, phone bridges, paging, and IR-retainer portals.
- The trigger and timestamp for switching to out-of-band communications.
- Participant verification and war-room access control.
- Preservation of decisions, approvals, containment orders, and notification records.
- Explicit review of whether the adversary can monitor mailboxes, chat exports, IdP logs, ticket queues, or endpoint-management tools.
- Named approver evidence for high-impact containment and public/regulatory communication actions.
- Return-to-normal criteria before resuming internal channels.
This should be a documentation-only skill enhancement with no new tool permissions.
