The Photon operating system must set the "umask" parameter correctly.
An XCCDF Rule
Description
The "umask" value influences the permissions assigned to files when they are created. The "umask" setting in "login.defs" controls the permissions for a new user's home directory. By setting the proper "umask", home directories will only allow the new user to read and write files there.
