For some of us,we don’t know what is the firewall ? for them the word ‘firewall’ literally invokes an image of a burning wall, rather than a savvy piece of security-enhancing computer software.

If you’re one of these people, then you should immediately contact IT support in Cape Town to answer your queries and instill a protective firewall on your computer, if necessary.

Introduction What is the Firewall:

A firewall essentially helps to block harmful hackers, vicious viruses, and worms from reaching your PC via the Internet.

It effectively controls the flow of communications traversing computer networks, by analyzing each one’s intended destination, characteristics, and source.

How does it work?

A firewall is, in a sense, exactly like a wall, screening your computer from the Internet and blocking harmful connections, according to rules that you define.

The Internet has some extremely destructive programs on it, maliciously intended to destroy your PC, therefore it is of paramount importance that you counteract these attacks using a firewall.

The two types of firewalls

Two kinds of firewalls exist:

  • Software
  • Hardware Varieties.

The software firewall is a program that you can install on your PC, while the hardware firewall is an actual device that can be plugged into your broadband router and computer.

What’s the difference between the two?

Software firewall:

How do you program it?

Firewalls usually have some basic rules built-in, but it’s up to you to program it to perform specific functions. Each time a new program you run requests an Internet connection, the firewall will alert you with a warning message.

If you’re unsure how to program your firewall, opt for IT support in Cape Town for help.
