UAH-ISM-0109 Event logs from workstations are analysed in a timely manner to detect cyber security events

Event logs from workstations are analysed in a timely manner to detect cyber security events. Required at Maturity Level Three of the User application hardening mitigation strategy (Appendix C); ISM control ISM-0109 in ASD's Essential Eight to ISM mapping (December 2023). ASD lists this event logging and incident requirement under User application hardening, so it is assessed for the events this strategy generates.

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.
