Check Text ( C-60924r905348_chk )
Verify the macOS system requires reauthentication when using the "sudo" command to elevate privileges with the following command: /usr/bin/sudo /usr/bin/grep -r "timestamp_timeout" /etc/sudoers* /etc/sudoers:Defaults timestamp_timeout=0 If conflicting results are returned, 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.

Verify the macOS system requires reauthentication when using the "sudo" command to elevate privileges with the following command:

/usr/bin/sudo /usr/bin/grep -r "timestamp_timeout" /etc/sudoers*

/etc/sudoers:Defaults timestamp_timeout=0

If conflicting results are returned, 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.
