TOSS 5 must define default permissions for the system default profile.

The "umask" controls the default access mode assigned to newly created files. A umask of 077 limits new files to mode 600 or less permissive. Although "umask "can be represented as a four-digit number, the first digit representing special access modes is typically ignored or required to be "0". This requirement applies to the globally configured system defaults and the local interactive user defaults for each account on the system.

Note: If the value of the "umask" parameter is set to "000" "/etc/profile" file, the severity is raised to a CAT I. Verify the "umask" setting is configured correctly in the "/etc/profile" file using the following command: $ grep umask /etc/profile umask 077 If the value for the "umask" parameter is not "077", or the "umask" parameter is missing or is commented out, this is a finding.

Configure TOSS 5 to define default permissions for all authenticated users in such a way that the user can only read and modify their own files. Add or edit the lines for the "umask" parameter in the "/etc/profile" file to "077": umask 077
