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 OL 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 Content

Verify that OL 9 configures the "/var/log/messages" file to be group-owned by root with the following command:

$ ls -la /var/log/messages
rw-------. 1 root root 564223 July 11 11:34 /var/log/messages

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