Ensure 'Idle timeout' is less than or equal to 10 minutes for Configuration utility sessions
Description
To set an idle timeout for GUI sessions PASS requires sys httpd auth-pam-idle-timeout between 1 and 600 seconds. Audited against tmsh output with defaults shown: save the concatenated output of 'tmsh list auth password-policy all-properties', 'tmsh list auth source all-properties', 'tmsh list auth remote-user all-properties', 'tmsh list auth radius all-properties', 'tmsh list sys httpd all-properties', 'tmsh list sys sshd all-properties', 'tmsh list sys global-settings all-properties', 'tmsh list cli global-settings all-properties', 'tmsh list sys ntp', 'tmsh list sys snmp all-properties', 'tmsh list sys syslog' and 'tmsh list net self all-properties'. Patterns are scoped to the named top-level block.
How it is checked
Audit method: Configuration pattern
- Pattern
(?m)^sys httpd \{\n(?:[ \t]+[^\n]*\n)*?[ \t]+auth-pam-idle-timeout (?:[1-9]\d?|[1-5]\d\d|600)[ \t]*$
How it is fixed
Fix method: Guidance or infrastructure patch
tmsh modify sys httpd auth-pam-idle-timeout 600 tmsh save sys config # CIS guidance: On Configuration utility: System > Preferences, Under Security settings...set the value of Idle Time Before Automatic Logout to 600 seconds
