Title

Ubuntu 22.04 LTS must configure the files used by the system journal to be owned by "root".

Control

Verify the /run/log/journal and /var/log/journal files are owned by "root" by using the following command: $ sudo find /run/log/journal /var/log/journal -type f -exec stat -c "%n %U" {} \; /var/log/journal/3b018e681c904487b11671b9c1987cce/system@99dcc72bb1134aaeae4bf157aa7606f4-0000000000003c7a-0006073f8d1c0fec.journal root /var/log/journal/3b018e681c904487b11671b9c1987cce/system.journal root /var/log/journal/3b018e681c904487b11671b9c1987cce/user-1000.journal root /var/log/journal/3b018e681c904487b11671b9c1987cce/user-1000@bdedf14602ff4081a77dc7a6debc8626-00000000000062a6-00060b4b414b617a.journal root /var/log/journal/3b018e681c904487b11671b9c1987cce/system@99dcc72bb1134aaeae4bf157aa7606f4-0000000000005301-000609a409 593.journal root /var/log/journal/3b018e681c904487b11671b9c1987cce/system@99dcc72bb1134aaeae4bf157aa7606f4-0000000000000001-000604dae53225ee.journal root /var/log/journal/3b018e681c904487b11671b9c1987cce/user-1000@bdedf14602ff4081a77dc7a6debc8626-000000000000083b-000604dae72c7e3b.journal root If any output returned is not owned by "root", this is a finding.

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.

Fix

Configure Ubuntu 22.04 LTS to set the appropriate ownership to the files used by the systemd journal. Create a drop-in file if it does not already exist with the following command: $ sudo vi /etc/tmpfiles.d/zzz-systemd-stig.conf Add or modify the following lines in the "/etc/tmpfiles.d/zzz-systemd-stig.conf" file: z /var/log/journal/%m/system.journal 0640 root systemd-journal - - Restart the system for the changes to take effect.
