Verify the audit log directory is owned by "root" to prevent unauthorized read access. Determine where the audit logs are stored with the following command: $ sudo grep -iw log_file /etc/audit/auditd.conf log_file = /var/log/audit/audit.log Determine the owner of the audit log directory by using the output of the above command (ex: "/var/log/audit/"). Run the following command with the correct audit log directory path: $ sudo ls -ld /var/log/audit drwx------ 2 root root 23 Jun 11 11:56 /var/log/audit If the audit log directory is not owned by "root", this is a finding.

Verify the audit log directory is owned by "root" to prevent unauthorized read access.

Determine where the audit logs are stored with the following command:

$ sudo grep -iw log_file /etc/audit/auditd.conf

log_file = /var/log/audit/audit.log

Determine the owner of the audit log directory by using the output of the above command (ex: "/var/log/audit/"). Run the following command with the correct audit log directory path:

$ sudo ls -ld /var/log/audit

drwx------ 2 root root 23 Jun 11 11:56 /var/log/audit

If the audit log directory is not owned by "root", this is a finding.

Fix Text (F-52123r779770_fix)
Configure the audit log to be protected from unauthorized read access by setting the correct owner as "root" with the following command: $ sudo chown root [audit_log_directory] Replace "[audit_log_directory]" with the correct audit log directory path. By default, this location is usually "/var/log/audit".
