Your Computer is not Safe without a Firewall

By Todd Domingo


All internet surfers should always have computer firewall protection.Without it, you are giving hackers permission to steal your computer files.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 keeps them out of your computer and keeps your files safe.

A firewall has the responsibility of shielding your computer from external forces that are working to bring harm to your computer.It does not matter if it is because of a computer worm, virus or Trojan, every computer should have firewall protection.In order for all of this to sink in, you have to know a little bit about computers and what makes them tick.A computer is designed to communicate and get messages from other computers in their network or messages from the internet.

Usually the larger companies will have computer networks, but if you have a home computer, then your computer receives messages from the internet only.Firewalls can work with individual and network computers. Their purpose is to monitor the communication flow from the computer to the internet.They will decide if these messages can enter the computer and where they can go.If a particular message does not seem right, it is automatically blocked from your computer's firewall.

Hardware and software are the main two kinds of firewalls.A hardware firewall is already installed on 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.It has to be installed on your computer in order to work.Also, it does not talk to other computers.It only monitors the messages that are intended for the computer in which it is installed.Software firewalls only work with 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.This is a very good observation, but both types of programs are needed.They work together to make sure that hackers cannot get to your 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, all computers need firewall protection.This is the case for both home and office computers.You do not want your files to be hacked.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 is a company that has a firewall log analyzer that can be utilized to track activity and hinder future threats.
