AWS Control Tower customized log retention
AWS Control Tower now provides the ability to customize the retention policy for Amazon Simple Storage Service (Amazon S3) buckets that store your AWS Control Tower CloudTrail logs. AWS Control Tower uses AWS CloudTrail to record logs of actions made by users, roles or AWS services. These logs are stored in Amazon S3 buckets, which are created in the core logging account. The Amazon S3 CloudTrail buckets have a retention policy that specifies the number of days after which the logs will get deleted. The default settings of 1-year for standard account logging and 10-years for access logging are applied if a user chooses not to customized their log retention policy.
