Description
Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity. If audit data were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity of audit data, the network device must protect audit information from unauthorized deletion. This requirement can be achieved through multiple methods, which will depend upon system architecture and design. Some commonly employed methods include ensuring log files receive the proper file system permissions using file system protections, restricting access, and backing up log data to ensure log data is retained. Network devices providing a user interface to audit data will leverage user permissions and roles identifying the user accessing the data and the corresponding rights the user enjoys to make access decisions regarding the deletion of audit data.

Who does this work

7 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.

Check Text (C-268255r1039643_chk)

Verify the operating system audit records have proper permissions and ownership. Log in to the HYCU console and list the full permissions and ownership of the audit log files with the following command: # sudo ls -la /var/log/audit total 4512 drwx------. 2 root root 23 Apr 25 16:53 . drwxr-xr-x. 17 root root 4096 Aug 9 13:09 .. -rw-------. 1 root root 8675309 Aug 9 12:54 audit.log Audit logs must be mode 0600 or less permissive. If any are more permissive, this is a finding. The owner and group owner of all audit log files must both be "root". If any other owner or group owner is listed, this is a finding.

Fix Text (F-72179r1038464_fix)

Change the mode of the audit log files with the following command: # chmod 0600 [audit_file] Change the owner and group owner of the audit log files with the following command: # chown root:root [audit_file]
