The Ubuntu operating system must generate audit records for all account creations, modifications, disabling, and termination events that affect /etc/group.

Description
Once an attacker establishes access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to create an account. Auditing account creation actions provides logging that can be used for forensic purposes. To address access requirements, many operating systems may be integrated with enterprise level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.

Who does this work

12 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-238239r958368_chk)

Verify the Ubuntu operating system generates audit records for all account creations, modifications, disabling, and termination events that affect "/etc/group". Check the currently configured audit rules with the following command: $ sudo auditctl -l | grep group -w /etc/group -p wa -k usergroup_modification If the command does not return a line that matches the example or the line is commented out, this is a finding. Note: The "-k" allows for specifying an arbitrary identifier, and the string after it does not need to match the example output above.

Fix Text (F-41408r653891_fix)

Configure the Ubuntu operating system to generate audit records for all account creations, modifications, disabling, and termination events that affect "/etc/group". Add or update the following rule to "/etc/audit/rules.d/stig.rules": -w /etc/group -p wa -k usergroup_modification To reload the rules file, issue the following command: $ sudo augenrules --load
