SLES-15-010350 - The SUSE operating system must prevent unauthorized users from accessing system error messages - permissions.local

Information

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 SUSE 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.

Solution

Configure the SUSE operating system to prevent unauthorized users from accessing system error messages.

Add or update the following rules in '/etc/permissions.local':

/var/log/messages root:root 640

Set the correct permissions with the following command:

> sudo chkstat --set --system
