4.4.4 Ensure server parameter 'audit_log_events' has 'CONNECTION' set for MySQL Database Server (Manual)​

Profile Applicability​

• Level 2

Description​

Set audit_log_enabled to include CONNECTION on MySQL Servers

Rationale​

Enabling CONNECTION helps MySQL Database to log items such as successful and failed connection attempts to the server. 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.
