Advice On How To Run A Firewall To Lock Down A New Dedi Server

This guide will show how to manage firewalls for server hosting. This guide will help you, if you tend to run your dedicated server in an automated fashion. This guide contains detailed instructions on how to install multiple profiles when server hosting (for all instance and purposes). These profiles can be both run manually and scheduled.

To configure the dedicated server, start it from the Dedicated Server profile. Configure the way you want your profile setup and start server hosting.

For security purposes it better to acquire BFD before installing a firewall on dedicated hosting servers. BFD is short for Brute Force Detection, which basically runs a SSH script to check if authenticity has been breached. Advanced Policy Firewall (APF) provides more than enough security for web hosting. APF provides a policy based iptable for configuration. It comes with a unique subset feature tailored for both veterans and novices.

Packaged in multiple formats APF is ideal for deployment on any environment. You will require root SSH access to your server to continue. Log in to your root user from su through SSH. Find your temporary folder and extract all packages. Next run the installation file. You will receive a confirmation message. Now that installation is done its time to configure the firewall. Let's go over the basics to get your firewall going. This guide does not contain every detail the APF has. You can go through the README file and the configuration file for details of all features. To find which networks have displayed suspicious activity you can check the 'block' list in DShield.org. To configure firewall ports, use 'common ingress' and 'common egress' commands in the Cpanel Servers. This could even work in the Ensim Servers. Start the firewall, but before that make sure you have saved all changes made. After launch you have commands available for actions like restart, flush, list, status, allow host, deny host etc. After confirming that everything is alright change the DEV. The firewall will clear itself automatically at 5 minutes interval unless you change it from cron. It is recommended for this value to be zero after you have checked everything. Once you have saved all your changes restart the firewall. To start APF at boot time automatically look for commands in the README.

APF recently added the AntiDOS feature, which can be accessed from logs. You might want look around here at all the features, but don't forget to check out the alerts by email feature. This feature is very useful when you are concerned with extra security. It is recommended to check the APF logs frequently to check hosts who have been denied or given access. If you need to block hosts you can start doing that now. If you want to block comments as well you should get the latest version of APF. As shown in the README use d flag before the IP address to deny them access.

Now you have fully functional firewall and a basic grasp on how to manage it.
