Hardware Firewall

A hardware firewall, otherwise known as a physical firewall, is an appliance that establishes a network boundary. It’s a set of appliances or devices that are used in defending the computer network. A hardware firewall is a device that connects a computer network to an external internet and acts as a barrier that protects the computer network from hacks or users that are not authorized to access the network.

A hardware firewall aids the cybersecurity of the computer network by filtering the traffic that gets through, which was established based on security policy, users profile, and rules. The boundary set, prevents against unauthorized access, inspects all inbound and outbound network traffic, and manifests controls and security policies.

How Hardware Firewall Works?

A hardware firewall is designed to protect an organization’s network by enforcing a boundary. It is located directly behind the router and can be configured to analyze the traffic to filter specific threats when it pass through the device. It acts like a digital filter to purify the traffic that goes into the computer network.

Normally a user would connect a network cable directly to a computer or server. But with a hardware firewall, the cable is connected to a firewall device first. This allow hardware firewall to serve as a protective barrier between the internet and the server.

A hardware firewall offers some advantages:

  • Control the traffic enter your server.
  • Apply specific rules for all traffic.
  • Free up server resources such as memory and processing power.

The simplest form of firewall is called packet filter. When a traffic enters within a firewall network, it undergoes security audit, and at times various sets of permissions are applied to it. Using the information the traffic carries such as source and location, firewall use this to decide whether the traffic can bring harms to the system or not.

Modern hardware firewalls can check both inbound and outbound traffic. As much as it blocks certain traffic from getting into the network, it also stops specific types of traffic from exiting the network with the same filtering mechanism. This aids the computer network from being exposed to hacks, leaks, and exploitation to other computer as well.
