Check Text (C-274014r1120030_chk)
Verify Amazon Linux 2023 requires reauthentication when using the "sudo" command to elevate privileges with the following command:
$ sudo grep -ir 'timestamp_timeout' /etc/sudoers /etc/sudoers.d/
/etc/sudoers:Defaults timestamp_timeout=0
If results are returned from more than one file location, this is a finding.
If "timestamp_timeout" is set to a negative number, is commented out, or no results are returned, this is a finding.
