Description
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

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-238317r991581_chk)

Verify the Ubuntu operating system generates audit records showing start and stop times for user access to the system via the "/var/log/btmp" file. Check the currently configured audit rules with the following command: $ sudo auditctl -l | grep '/var/log/btmp' -w /var/log/btmp -p wa -k logins If the command does not return a line matching 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-41486r654125_fix)

Configure the audit system to generate audit events showing start and stop times for user access via the "/var/log/btmp file". Add or update the following rules in the "/etc/audit/rules.d/stig.rules" file: -w /var/log/btmp -p wa -k logins To reload the rules file, issue the following command: $ sudo augenrules --load
