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 RHEL 9 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 Procedure

Verify the "/var/log" directory is group-owned by root with the following command:

$ stat -c "%G %n" /var/log

root /var/log

If "/var/log" does not have a group owner of "root", this is a finding.

Fix Action

Configure the group owner of the directory "/var/log" to "root" by running the following command:

$ sudo chgrp root /var/log
