To ensure the default umask for users of the C shell is set properly,
add or correct the 'umask' setting in '/etc/csh.cshrc' to read as follows:
'umask 077
Parameter:
[027_umask]
Technical Mechanism:
The umask value influences the permissions assigned to files when they are created.
A misconfigured umask value could result in files with excessive permissions that can be read or
written to by unauthorized users.
