Title

Ubuntu 24.04 LTS must configure /var/log/syslog file with mode "0640" or less permissive.

Control

Verify that Ubuntu 24.04 LTS configures the /var/log/syslog file with mode "0640" or less permissive with the following command: $ stat -c "%n %a" /var/log/syslog /var/log/syslog 640 If a value of "640" or less permissive is not returned, this is a finding.

Discussion

Only authorized personnel are to be made aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state or can identify Ubuntu 24.04 LTS 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.
