To ensure the default umask controlled by '/etc/login.defs' is set properly,
add or correct the 'UMASK' setting in '/etc/login.defs' 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 and
written to by unauthorized users.
