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 value other than "0" (including negative numbers), is commented out, or is missing entirely, this is a finding.
Configure Amazon Linux 2023 to reauthenticate "sudo" commands after the specified timeout:
Add the following line to "/etc/sudoers" or a file in "/etc/sudoers.d":
Defaults timestamp_timeout=0
