Understanding the hardware firewall

A hardware firewall is a physical device responsible for filtering traffic coming to your website. This is achieved by placing a firewall between the uplink and the computer. 

It makes use of powerful network components (hardware and software) and force all traffic through the connection through configurable rule sets that grant or deny access accordingly. 

Features of hardware firewall are already set. They check the incoming and outgoing traffic of the computer and, according to some simple rules, allow or deny such traffic. 

Some common examples of software firewalls that you may be familiar with are:-

  • WindowsFirewall
  • UFW
  • IPTables
  • FirewallD

 The hardware firewall is the same unless it is outside the server. 

Software vs Hardware Firewalls

The primary difference between hardware firewall and software firewall is that the hardware firewall runs on a physical device. A software firewall can be installed on a machine. Many operating systems including Windows and MacOS come with software firewalls installed on the machines. Software firewall does not need any dedicated hardware but can be installed on any machine.

How does the hardware firewall work?

The firewall is located outside the server and connects directly to the uplink. If this is a new configuration, the firewall will connect to the server. 

If this is a new configuration for production servers, a maintenance window is scheduled to manage physical connections.

Once the connection to the server is established, all traffic to and from the server passes through the firewall. Traffic is forced to pass the verification. exceeds the type of traffic it receives, which is very important. 

Here are five main advantages that hardware firewalls provide: 

  1. Traffic Control: Ability to decide which traffic should and should not reach your server. 
  1. Default Rules: A fully configurable list of default rules that can be applied to all traffic. 
  1. Access to the Port: Thin controls to customize rules, such as allowing all traffic to your website, or ensuring that only you and your developers have access to ssh or rdp ports. 
  1. Management equals flight control: Access a fully staffed network computer to configure, troubleshoot, or adjust controls at any time. 
  1. Other Server Resources: You can even disable software firewalls from the server and rely entirely on hardware firewalls. Freeing up valuable processors and memory for continuous successful functions and services for your business needs. 

Other Benefits of Hardware Firewalls

One of the major advantage of hardware firewalls is benefit is the ability to run VPN connections. This connection is also a fully managed product that enables security, access, and encryption of your already secure server.
