How Does A Network Security Firewall Work?


If you have a business that runs on any kind of computer network, you know the importance of security. The backbone of any business is the IT component. Strengthening and stabilizing it affects the integrity of your business. It’s imperative to keep your network and business secure because once a malware infiltrates your system, it could create major issues in the long run. Thankfully, you can avoid this from happening by installing a network security firewall.

What is a Network Security Firewall?

Imagine that your business is a fortress and that enemy factions are constantly trying to infiltrate. In the case of your computer network, this is an accurate metaphor. Malware and shadow software are always trying to get in. If they do, they could wreak havoc. Interruptions in service not only mean disruptions to growth, but they also have financial consequences. Fixing a breach can cost you valuable time and money. You wouldn’t protect your fortress with paper walls. You’d want stone or steel because you need something impenetrable. It’s the same with your network.

To protect your network from attacks, you need a strong barrier. What is that barrier called? A network security firewall.

Simply put, a network security firewall is a piece of tech that monitors and controls all incoming and outgoing network traffic. Security rules for your firewall can be predetermined. It acts as a boundary between the trusted internal network and the untrusted external network. If anything tries to breach the boundary, it will be denied entry.

Defense and Filter

The job of a network security firewall can be divided into two categories. The first is protection. Like in the fortress metaphor, it protects the fortress (network) from infiltrators (malware) attempting to invade it. In this way, it acts as a protective barrier.

Firewalls can work as filters too. They monitor every traffic that comes from unsecured sources going to your computer’s ports. The logic is simple. If the firewall detects that the source addresses can be trusted, then they’re allowed to access any port. If not, they’re further filtered to prevent them from infecting your system.

Utmost Importance

It’s clear that security is important, especially for business owners. A system is only as strong as its weakest link. If there are weak spots in your system, it may be vulnerable to attack or infiltration. If, on the other hand, your system is reinforced, the whole network is safer.
