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.How do you describe a firewall?It is a computer wall that shields the computer from the internet.It makes it almost impossible for hackers to invade your personal computer space.It makes it hard for hackers to get to your files.

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 work with either scenario. Their purpose is to monitor the communication flow from the computer to the internet. They have the responsibility of allowing certain messages to get to your computer.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 hareware computer is built into the computer.It checks up on messages that are sent from network computers and the one that go from network computers to the internet.A software firewall operates in the same way, but it is not already a part of your computer.You have to install it in order for it to function.Also it does not communicate with multiple computers.It only monitors the messages that are intended for the computer in which it is installed.Software firewalls can only monitor one computer.However, hardware firewalls can monitor all computers in a network.

But there are some people who do not think that a firewall is needed if a computer has anti-virus protection.You might have a good point, but you should not take the chance and delete your firewall protection because it works in combination with the anti-virus protection.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.Unfortunately, hackers have been known to mess up computers by wiping out the code and adjusting the 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 same logic for both corporate computers, as well as home office computers.You do not want to expose your private files to computer hackers.They are always searching for new and improved ways to get access to your computer and cause harm.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 has a firewall log analyzer that can help you to monitor your firewall and provide reports that can help you to ward off future attacks if they should ever occur.
