Description
sudo command does not require reauthentication if !authenticate option is specified in /etc/sudoers config file, or config files in /etc/sudoers.d/ directory. With this tag in sudoers, users are not required to reauthenticate for privilege escalation.

Who does this work

13 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-215261r1050789_chk)

If sudo is not used on AIX, this is Not Applicable. Run the following command to find "!authenticate" option in "/etc/sudoers" file: # grep "!authenticate" /etc/sudoers If there is a "!authenticate" option found in "/etc/sudoers" file, this is a finding. Run the following command to find "!authenticate" option in one of the sudo config files in "/etc/sudoers.d/" directory: # find /etc/sudoers.d -type f -exec grep -l "!authenticate" {} \; The above command displays all sudo config files that are in "/etc/sudoers.d/" directory and they contain the "!authenticate" option. If above command found a config file that is in "/etc/sudoers.d/" directory and that contains the "!authenticate" option, this is a finding.

Fix Text (F-16457r294235_fix)

Edit "/etc/sudoers" using "visudo" command to remove all the "!authenticate" options: # visudo -f /etc/sudoers Editing a sudo config file that is in "/etc/sudoers.d/" directory and contains "!authenticate" options, use the "visudo" command as follows: # visudo -f /etc/sudoers.d/<config_file_name>
