ADMIN-ISM-1906 Event logs from internet-facing servers are analysed in a timely manner to detect cyber security events

Event logs from internet-facing servers are analysed in a timely manner to detect cyber security events. Required at Maturity Levels Two and Three of the Restrict administrative privileges mitigation strategy (Appendices B and C); ISM control ISM-1906 in ASD's Essential Eight to ISM mapping (December 2023). ASD lists this event logging and incident requirement under Restrict administrative privileges, 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.

First move

No system holds this evidence for you: it is people and documents. Reminders and routing to the owner still save time. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date.
