# Cloud Logging bucket for Security logs: Cloud Audit, Access Transparency Logs, and Data Access Logs
# Logs are routed using a log sink to a central logging project into a dedicated log bucket
# AU-7, AU-9 - The log buckets created within the Logging project are immutable. These buckets have a retention policy of 365 days and IAM Policy that defines who has access to the bucket
# AU-4(1), AU-6(4), AU-9(2) - Log sinks sending the logs to same project in same region having a logging bucket
# AU-9(4), SI-4 - The centralized logging solution has a configuration in place that defines all logging buckets to be locked
# AU-11 - Logging bucket retention configuration
