Disabling Security for a WebCC Server on GNU/Linux

GNU/Linux comes bundled with two core security components: 

  • A firewall (typically either iptables or firewalld), which will block incoming connections that were not specifically allowed.
  • SELinux, a kernel security module that enforces access control policies on software, files and network resources.

The default configuration for these components will prevent clients from connecting to a WebCC server. This installation guide provides instructions on how to add security exceptions to these components so that they do not have to be disabled. However, you may prefer to disable them so as to simplify the installation process or to rule out security components as possible causes when troubleshooting an issue.

IMPORTANT: If you choose to disable security on GNU/Linux, it is critical to ensure that your domain has effective site-wide security mechanisms to prevent unauthorized access to your WebCC server.
