Details
Check Text (C-269362r1050245_chk)
Verify AlmaLinux OS 9 requires reauthentication when using the "sudo" command to elevate privileges with the following command:
$ grep timestamp_timeout /etc/sudoers /etc/sudoers.d/*
/etc/sudoers.d/01_stig:Defaults timestamp_timeout=0
If "timestamp_timeout" is set to a negative number, is commented out, conflicting results or no results are returned, this is a finding.
Fix Text (F-73294r1049551_fix)
Configure AlmaLinux OS 9 to reauthenticate "sudo" commands after the specified timeout:
Add the following line to "/etc/sudoers" or a file within "/etc/sudoers.d/":
Defaults timestamp_timeout=0
