Unattended terminal session timeout is 900 seconds (or less) - readonly
보통레벨 2자동aix
설명
TMOUT and TIMEOUT are environmental settings that activate the timeout of a shell. readonly TMOUT both exports and locks the variable, preventing unwanted modification during run-time. All systems are vulnerable if terminals are left logged in and unattended. Audit: /etc/profile must set TMOUT and TIMEOUT to 1-900 seconds and mark them readonly.
