RHEL-10-400185 - RHEL 10 must set mode "0600" or less permissive for the audit logs file to prevent unauthorized access to the audit log.

Information

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 RHEL 10 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.

Solution

Configure RHEL 10 audit logs to have a mode of "0600" with the following command:

Replace "[audit_log_file]" with the path to each audit log file. By default, these logs are located in "/var/log/audit/":

$ sudo chmod 0600 /var/log/audit/[audit_log_file]

Check the group that owns the system audit logs:

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

If "log_group" is set to a user other than "root", configure the permissions the following way:

$ sudo chmod 0640 $log_file
$ sudo chmod 0440 $log_file.*

Otherwise, configure the permissions the following way:

$ sudo chmod 0600 $log_file
$ sudo chmod 0400 $log_file.*
