Ensure access on root user smit.log is configured

YüksekDüzey 1Otomatikaix

Açıklama

The smit.log file int the HOME directory of root maintains a history of all smit commands run as root. The smit.log file may contain sensitive information regarding system configuration, which may be of interest to an attacker. This log file must be secured from unauthorized access and modifications. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
