Blood on the logs

Your security audit shows an access event, but the question remains: who accessed what and when?

ISO 27001 demands not just protecting data, but proving control over it. Clause A.12.4.1 is explicit — event logs must record user activities, exceptions, and security events. This is not optional. Without accurate audit trails, certification fails and risk rises.

To meet the standard, your logging must capture:

• Identity: map every action to a verified user or system account.
• Object Accessed: file, database row, API endpoint — recorded with exact resource identifiers.
• Timestamp: precise, consistent, and in UTC to avoid ambiguity.
• Action Type: read, write, delete, modify, execute.
• Success or Failure: log both attempted and successful actions for full traceability.

The “who accessed what and when” requirement is tied to integrity and accountability. Logs must be tamper-resistant. Access to logs must itself be logged. Retention policies need to be long enough to cover incident investigations, often 6 to 12 months minimum per ISO recommendations.

Automation reduces human error. Centralized log management ensures correlation across systems. Access monitoring should trigger alerts when unusual patterns emerge — multiple failed logins, mass downloads, or off-hours edits. This is how compliance and security align.

Proof of compliance means producing these records fast. Auditors will ask to see them. Breaches demand them. Without them, response time stretches and trust collapses. ISO 27001 is clear: if you cannot show who accessed what and when, you have lost control of your information.
