Sections marked From the standard summarise SACS-210. Sections marked Vaurely guidance are our own practical advice, not Aramco or audit firm requirements: your authorised audit firm may assess things differently.

What the control requiresFrom the standard

  • Protection of event logs from alteration, disclosure, destruction, unauthorised access and unauthorised release.

How to implement itVaurely guidance

Menu names and licence requirements change over time: check the current Microsoft or Google documentation.

Microsoft 365 · Entra ID · Intune

  • Restrict audit log access to named roles in Purview; export logs to storage with immutability if you keep them longer than the default retention.

Google Workspace

  • Restrict access to audit and investigation tools via admin roles; export logs (e.g. to BigQuery) if you need longer retention.

Evidence to prepareVaurely guidance

Aramco’s CCC program requires recent, time-stamped and clearly labelled evidence for each control. The list below is what we recommend preparing; the audit firm decides what it accepts.

  • List of who can read or delete logs; retention and immutability settings.

Common mistakesVaurely guidance

  • Every IT admin can delete logs; no record of who accessed them.
