Quick NIX Secure Script is used to harden and secure basic permissions and ownership on the fly. This script can be used during boot up, cron, bootstrapping, kickstart, jumpstart and during other system deployments. I recommend using CM tools like Puppet or Ansible, but this is still nice. Many times in (prod)uction world prior admins harden without automation or towards an industry baseline. This is to help get to a point of standardization and quickly set or reset basic system security.
