where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

  • Incident tickets for a sample period showing detection, containment, eradication and recovery steps · Ticketing / ITSM

periodic reviewEvidence produced at each review

  • Tabletop and live exercise after action reports · Document repository
  • Incident ticket samples covering detection, containment, and lessons learned · Ticketing / ITSM

governing documentDocuments that govern the control

  • SSP IR-4 statement describing the incident handling lifecycle, tools and coordination with contingency planning · Document repository
  • Incident response plan with severity definitions and escalation paths · Policy repository / GRC workspace
  • Incident response team roster with on call rotation · Document repository

First move

Mostly documents and reviews. Pull the 1 system-held artefact from your Ticketing / ITSM on a schedule; put the documents under version control with an owner and review date, and log each review as a dated record with a named reviewer.
