Discussion

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.

At the command line, run the following command:

# grep ^UMASK /etc/login.defs

Example result:

UMASK 077

If "UMASK" is not configured to "077", this a finding.

Note: "UMASK" should only be specified once in login.defs.
