Description:
Enable audit_log_enabled on MySQL Servers.
Rationale:
Enabling audit_log_enabled helps MySQL Database to log items such as connection attempts to the server, DDL/DML access, and more. Log data can be used to identify, troubleshoot, and repair configuration errors and suboptimal performance.
Impact:
There are further costs incurred for storage of logs. For high traffic databases these logs
will be significant. Determine your organization's needs before enabling.
