The SUSE operating system must reauthenticate users when changing authenticators, roles, or escalating privileges.

Description
Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When the SUSE operating system provides the capability to change user authenticators, change security roles, or escalate a functional capability, it is critical the user reauthenticate. Satisfies: SRG-OS-000373-GPOS-00156, SRG-OS-000373-GPOS-00157, SRG-OS-000373-GPOS-00158

Who does this work

8 NICE work roles and 7 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.

Details

Check Text (C-234853r1050789_chk)

Verify that the SUSE operating system requires reauthentication when changing authenticators, roles, or escalating privileges. Check that "/etc/sudoers" has no occurrences of "NOPASSWD" or "!authenticate" with the following command: > sudo egrep -i '(nopasswd|!authenticate)' /etc/sudoers If any uncommented lines containing "!authenticate", or "NOPASSWD" are returned and active accounts on the system have valid passwords, this is a finding.

Fix Text (F-38004r618829_fix)

Configure the SUSE operating system to remove any occurrence of "NOPASSWD" or "!authenticate" found in the "/etc/sudoers" file. If the system does not use passwords for authentication, the "NOPASSWD" tag may exist in the file.
