title: 'Ensure that Users Have Sensible Umask Values'

description: |-
    The umask setting controls the default permissions
    for the creation of new files.
    With a default <tt>umask</tt> setting of 077, files and directories
    created by users will not be readable by any other user on the
    system. Users who wish to make specific files group- or
    world-readable can accomplish this by using the chmod command.
    Additionally, users can make all their files readable to their
    group by default by setting a <tt>umask</tt> of 027 in their shell
    configuration files. If default per-user groups exist (that is, if
    every user has a default group whose name is the same as that
    user's username and whose only member is the user), then it may
    even be safe for users to select a <tt>umask</tt> of 007, making it very
    easy to intentionally share files with groups of which the user is
    a member.
