Guideline
Guidelines for personnel securityPrivileged access events are centrally logged.
Source: ASD Information Security Manual (ISM)
Plain language
Logging privileged access events means keeping a central record every time someone uses high-level permissions to access important systems. This is crucial because if something goes wrong, like sensitive data being leaked or a system being tampered with, you'll know who had special access and can quickly investigate.
Why it matters
Without centralised logging of privileged access events, misuse may go undetected, delaying response and enabling breaches or system compromise.
Operational notes
Forward privileged access events to a central log platform (e.g., SIEM), validate time sync, and alert on privileged logons and admin actions.
Implementation tips
- IT team should establish central logging: They should set up a system to automatically record privileged access events. This can be done by configuring programs that track who accessed systems and when, then storing these logs securely.
- System administrators should define what privileged access means: They should list which roles or actions count as 'privileged' so everyone knows what needs to be logged. This involves writing down specific access levels or accounts that have greater permissions than regular users.
- Managers should train staff on logging importance: Managers must educate their team about why logging privileged access is essential. This could be achieved through meetings or training sessions that explain the potential risks of not doing it.
- IT security staff should regularly review access logs: They should look through the logs frequently to spot any unusual or unauthorised access. This involves checking the records against expected access patterns and investigating any discrepancies.
- Organisation leaders should ensure that logging follows ACSC guidelines: They should verify that the logging setup adheres to the Australian Cyber Security Centre’s standards by consulting the guidelines and possibly engaging an external review.
Audit / evidence tips
-
Ask: the privileged access log policy: Request documentation that outlines the process for logging privileged access and who is responsible for it
Good: is a comprehensive policy that names responsible roles and specifies logging procedures
-
Ask: recent access logs: Obtain samples of privileged access logs from the last 30 days
Good: is detailed logs that are easy to cross-reference with known access activities
-
Ask: records of log reviews: Request evidence that logs are regularly reviewed by the IT security team
Good: is documentation showing regular reviews and follow-up on any anomalies
-
Ask: training records on logging procedures: Request proof that staff have been trained on the importance of logging privileged access
Good: is dated records of training sessions with evidence of participation
-
Ask: a compliance check report: Request a report or external review that shows compliance with ACSC guidelines on privileged access logging
Good: is a report validating that the logging process meets national standards
