Discussion

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.

Verify the "umask" setting is configured correctly in the "/etc/csh.cshrc" file using the following command:

Note: If the value of the "umask" parameter is set to "000" "/etc/csh.cshrc" file, the severity is raised to a CAT I.

$ grep umask /etc/csh.cshrc 

umask 077
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.
