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.

  1. From Azure Home select the Portal Menu
  2. Select your Azure Database for MySQL server
  3. For each database, under the Settings section in the sidebar, select Server parameters
  4. Ensure the audit_log_enabled parameter is set to ON
  5. Review the event types to be logged by updating the audit_log_events parameter; ensure CONNECTION is set
