Title

Ubuntu OS must be configured so that the "journalctl" command is group-owned by "root". (Cat II impact)

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 operating 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 the "journalctl" command is group-owned by "root" by using the following command: $ sudo find /usr/bin/journalctl -exec stat -c "%n %G" {} \; /usr/bin/journalctl root If "journalctl" is not group-owned by "root", this is a finding.

Fix Text

Configure "journalctl" to be group-owned by "root": $ sudo chown :root /usr/bin/journalctl
