Discussion

Only authorized personnel should be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state or can identify the NixOS system or platform. Additionally, Personally Identifiable Information (PII) and operational information must not be revealed through error messages to unauthorized personnel or their designated representatives. The structure and content of error messages must be carefully considered by the organization and development team. The extent to which the information system is able to identify and handle error conditions is guided by organizational policy and operational requirements.

Check Content

Verify the audit directory and logs are group-owned by "root". 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 location of the audit log file (if not specified, the default location is "/var/log/audit/audit.log"), determine if the audit log is group-owned by "root" using the following command:

$ sudo find /var/log/audit -exec stat -c "%G %n" {} \;

root /var/log/audit
root /var/log/audit/audit.log

If the audit directory and logs are not group-owned by "root", this is a finding.
