Your Computer is not Safe without a Firewall

By Todd Domingo


Everyone who surfs the internet should have a firewall installed on their computer.When you do not have one, this tells hackers that they have your approval to steal your personal documents.What is the definition of a firewall?Think of it as a form of protection between your computer and the internet.It makes it almost impossible for hackers to invade your personal computer space.It protects your computer from hackers and the internet world.

A firewall has the responsibility of shielding your computer from external forces that are working to bring harm to your computer.Whether it is an actual hacker, a virus or a worm, all personal computers need firewalls.Before you can truly understand this whole concept, you should first be knowledgeable about how computers and firewalls work together.A computer is made to get messages from internet and the other computers that are in the network.

Normally, big companies have many computers within their network, but a home computer generally only has one.Firewalls can work with individual and network computers. They are created to communicate between various computers and the online world.They will decide if these messages can enter the computer and where they can go.If a certain message does not seem appropriate, then your computer firewall will block it.

The two types of firewalls are hardware and software.A hardware firewall is already installed on the computer.It monitors messages that go between the internet and network computers.A software firewall works in the same manner, but it is not already a part of your computer.It has to be installed on your computer in order to work.In addition, it does not communicate with other computers.It only monitors the messages that are intended for the computer in which it is installed.Software firewalls were only made to work with one computer.However, hardware firewalls can monitor all computers in a network.

However, there are some who may question why it is needed if you have anti-virus protection on your computer.This is a very good observation, but both types of programs are needed.They work together to keep hackers out of your personal files.They are both needed so that there is a possible double shield that will keep hackers away from your computer.The bad thing is that most hackers can cause damage to your computer by changing the codes and settings.Also, they can cause even more damage to you by totally wrecking someone else's computer and making it seem like you did the dirty work.

In conclusion, every computer should have a firewall.This is the case for both home and office computers.You do not want confidential information exposed to hackers.They are constantly trolling the internet trying to find new ways to harm others.If this is a thought that does not sit too well with you, then you can always opt for products that can help you to control such threats.manageengine owns a firewall log analyzer that monitors firewalls and offers reports that you can use to manage future threats.
