| Description | ||||
| The file /etc/sudoers must include a timestamp_timout of 0. Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When operating systems provide the capability to escalate a functional capability or change user authenticators, it is critical the user reauthenticate.

Verify the macOS system requires reauthentication when using the "sudo" command to elevate privileges with the following command:
/usr/bin/sudo /usr/bin/sudo -V | /usr/bin/grep -c "Authentication timestamp timeout: 0.0 minutes"
If the result is not "1", this is a finding.
