Description
If audit information 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 information, the operating system must protect audit information from unauthorized deletion. This requirement can be achieved through multiple methods, which will depend upon system architecture and design. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit information system activity.

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-275686r1148108_chk)

Verify the audit log directory has a mode of "750" or less permissive. Determine where the audit logs are stored by using the following command: $ sudo grep -iw log_file /etc/audit/auditd.conf log_file = /var/log/audit/audit.log Using the path of the directory containing the audit logs, determine if the directory has a mode of "750" or less by using the following command: $ sudo stat -c "%n %a" /var/log/audit /var/log/audit 750 If the audit log directory has a mode more permissive than "750", this is a finding.

Fix Text (F-79693r1148107_fix)

Configure the audit log directory to have a mode of "750" or less permissive. Using the path of the directory containing the audit logs, configure the audit log directory to have a mode of "750" or less permissive by using the following command: $ sudo chmod -R g-w,o-rwx /var/log/audit
