Ensure sudo logging is active

高レベル 2自動aix

説明

All commands executed via sudo should be logged to either syslog (default) or a dedicated log file Note: visudo edits the sudoers file in a safe fashion, analogous to vipw(8). visudo locks the sudoers file against multiple simultaneous edits, provides basic sanity checks, and checks or parse errors. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
