OS commands and libraries must have the proper permissions to protect from unauthorized access

Description

Verify that the SUSE operating system prevents unauthorized users from accessing system command and library files. Check that all of the audit information files and folders have the correct permissions with the following command:

# sudo chkstat --warn --system

Set the correct permissions with the following command:

# sudo chkstat --set --system

Rationale

If the SUSE operating system were to allow any user to make changes to software libraries, those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. This requirement applies to SUSE operating systems with software libraries that are accessible and configurable, as in the case of interpreted languages. Software libraries also include privileged programs that execute with escalated privileges. Only qualified and authorized individuals must be allowed to obtain access to information system components to initiate changes, including upgrades and modifications.
