How to Preserve Cloud Audit Logs During a Security Investigation

Cloud audit records can be essential for tracing account activity, configuration changes, and data access. During an investigation, the relevant logs may be split across identity, storage, network, and application services, each with different retention periods. Waiting until the investigation is complete to export them can leave gaps.

Identify the evidence sources

Record the affected accounts, resources, time range, and regions. Check whether organization-level audit logs, identity sign-ins, object access, and network flow records are enabled. Preserve original timestamps and metadata when exporting.

• Restrict access to copies and record who collected them.
• Keep a read-only copy in an approved evidence location.
• Document missing sources and retention limits.
• Coordinate with legal or privacy owners when evidence contains personal data.
