ASD ISM 0585 Capture detailed information in event logs
What it says
For each event logged, the date and time of the event, the relevant user or process, the relevant filename, the event description, and the information technology equipment involved are captured.
Quoted as published. Everything else on this page is written by Control Stack.
What it means
In plain EnglishRecord details like time, user, and equipment for each logged event.
This control is about keeping a detailed record every time something significant happens in your computer systems. It includes noting the time, who was involved, and the equipment used. If we don't do this, it would be really hard to figure out what went wrong in case of a cyber attack or technical issue, and we might not know how to stop it from happening again.

Why it matters
If event logs lack key fields (time, user/process, filename and device), investigations take longer, root cause may be missed, and incident impact increases.
How to implement
IT team should make sure that all systems are set up to automatically log key events.
They can do this by configuring the system settings to capture details like when and what happens, who is involved, and which computer or equipment is used.
Managers should work with the IT team to identify key events that need to be logged.
To do this, they can sit down and list out typical activities and incidents that must be tracked, and how these logs will help in solving problems later.
HR should communicate with staff about the importance of keeping accurate records for logged events.
This could involve sending newsletters or holding brief training sessions to explain why this is important and what they need to do to help.
System owners should periodically review logs to ensure all necessary information is being recorded correctly.
They can set up monthly checks where they randomly select log entries to review and confirm all required details like time, user, and equipment are captured.
Procurement teams should ensure that any new software or technology being purchased supports detailed event logging.
Before buying, they can ask vendors for assurance that their products include these features and can be configured to meet these needs.
Keep it running
Audit log configurations to ensure each record includes date/time, user or process, filename, event description and the IT equipment identifier; alert on missing fields.

Mappings
Closest match in ISO/IEC 27001: A.8.15, Logging of activities and events, which this control partially meets.
ISO/IEC 27001: 3 mappings
This control partially meets A.8.15.
ISM-0585 requires each logged event to capture specific fields (date/time, user or process, filename, description, and the IT equipment involved). ISO/IEC 27001:2022 Annex A 8.15 requires organisations to produce, store, protect and analyse logs of relevant events, which presumes logs contain enough context to be useful. Annex A 8.15 is broader because it governs the end-to-end logging lifecycle, while ISM-0585 is a detailed content requirement for individual log records.
This control supports A.8.16.
ISM-0585 requires log entries to include sufficient detail (time, user/process, filename where relevant, event description, and equipment) to interpret activity. ISO/IEC 27001:2022 Annex A 8.16 requires monitoring of networks, systems and applications for anomalous behaviour and taking actions to evaluate potential incidents, which relies on high-quality telemetry to detect and triage anomalies. Annex A 8.16 is about monitoring and operational response, while ISM-0585 improves the fidelity of the underlying event data used for that monitoring.
This control depends on A.8.17.
ISM-0585 requires that the date and time of each logged event are captured. ISO/IEC 27001:2022 Annex A 8.17 requires system clocks to be synchronised to approved time sources so those timestamps are accurate and comparable across systems. Without Annex A 8.17-style clock synchronisation, ISM-0585 can be met superficially but the recorded times may not support reliable correlation or investigation.
ISO/IEC 42001: 1 mapping
This control partially overlaps A.6.2.8.
Annex A 6.2.8 requires enabling event logs for AI systems at defined life cycle phases, at minimum during operational use. ISM-0585 specifies the required content of each logged event (e.g. time, user/process, filename, description, and equipment), which complements the AI system logging requirement by defining what good event logs should contain. Annex A 6.2.8 focuses on when logging is enabled, while ISM-0585 focuses on the minimum fields/attributes captured once logging exists.
ASD Essential Eight: 4 mappings
This control partially overlaps E8-MF-ML2.6.
ISM-0585 requires logs to capture date/time and the relevant user or process, plus descriptive and asset context for each event. ASD Essential Eight E8-MF-ML2.6 requires successful and unsuccessful multi-factor authentication events to be centrally logged, which overlaps because MFA events must record the actor and timestamp to support investigation. E8-MF-ML2.6 is specific to MFA and mandates central logging, while ISM-0585 applies to all logged events and focuses on the minimum fields within each record.
This control partially overlaps E8-RA-ML2.6.
ISM-0585 requires consistent per-event fields such as who/what initiated an action, when it occurred, and which system and object were involved. ASD Essential Eight E8-RA-ML2.6 requires privileged access events to be centrally logged, which overlaps because those privileged events still need the attribution and time details ISM-0585 mandates. E8-RA-ML2.6 is narrower on event scope (privileged activity) and adds centralisation, while ISM-0585 is a general log-content requirement across event types.
- E8-RA-ML2.7Centrally log privileged user account and security group management eventsPartially overlaps
This control partially overlaps E8-RA-ML2.7.
E8-RA-ML2.7 requires central logging of privileged account and group management events. ISM-0585 requires that, for each event logged, key details such as timestamp, user/process, description and equipment involved are captured, improving the usefulness of those centrally collected privileged-management logs. E8-RA-ML2.7 focuses on ensuring the right privileged management events are centrally collected, while ISM-0585 focuses on the completeness and fields within any logged events.
This control depends on E8-AH-ML2.12.
E8-AH-ML2.12 requires central logging of command line process creation events. ISM-0585 requires that logged events capture key fields such as date/time, user or process, filename and equipment involved, which are essential to make command line process creation logs actionable. ISM-0585 strengthens E8-AH-ML2.12 by improving the quality and investigative value of the centrally collected process creation records.
ASD Essentials for enterprise IT: 3 mappings
- IT.DET-01.2Forward high-value security logs and configuration changes to central log storagePartially overlaps
This control partially overlaps IT.DET-01.2.
IT.DET-01.2 requires high-value, security-relevant event logs and configuration changes to be forwarded to central log storage; ISM-0585 requires each logged event to capture date and time, user or process, filename, description and IT equipment involved, defining their content.

This control partially overlaps IT.DET-02.1.
IT.DET-02.1 requires event logs to be normalised, time-synchronised and enriched to support correlation across systems; ISM-0585 requires each logged event to capture date and time, user or process, filename, description and IT equipment involved, detail that aids correlation.
- IT.PRO-05.3Log every administrative and management change with user, timestamp and targetPartially overlaps
This control partially overlaps IT.PRO-05.3.
IT.PRO-05.3 requires every administrative change to systems, configurations or controls to be recorded with the user, timestamp and target; ISM-0585 requires each logged event to capture the date and time, user or process, filename, description and equipment involved, overlapping on those details.
