Discussion

Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit NixOS system activity.

Check Content

Verify that the audit log directory has a mode of "0700" or less permissive.

First, determine where the audit logs are stored with the following command:

$ sudo grep log_file /etc/audit/auditd.conf
log_file = /var/log/audit/audit.log

Using the path of the directory containing the audit logs, check if the audit log directory has a mode of "0700" or less by using the following command:

$ sudo find /var/log/audit -type d -exec stat -c "%a %n" {} \;
700 /var/log/audit

If the audit log directory (or any subfolders) has a mode more permissive than "0700", this is a finding.
