Computer security, in basic terms means keeping your computer and data in a safe and secure. More of our personal data is stored in or accessed from our computer, now more than ever. However, most people lack the basic understanding of how to keep your computer safe. Following just a few simple rules that can improve overall computer security.

The first thing to understand is what exactly it means to be connected to the Internet. The computer connected to the Internet is similar to its home in many ways. There are many ways at home. Windows, doors, windows and doors you have, the more ways one has at home. An open door does not necessarily mean you are going to be stolen, but does not improve the odds. To complicate things, you think you are blocked, can not be because the lock is faulty or the door itself may have an undiscovered defect that allows easy access for intruders to his home.

Your computer has many windows and doors, not all are blocked. New defects are found every day, often with the correction does not come until days later. Like you would not leave the door open, do not leave your computer open either. The first two things that we will discuss to help with this task are to install a quality firewall and regularly updating the software installed.

Updating your software is becoming easier these days, especially the operating system. Do not have time to go into detail here about the many ways to update the software packages you may have or use, but overall the software manufacturer provides a way to do this automatically via the Internet. A good example is the update feature of Microsoft Windows. Make sure you get the updates for everything installed on your computer, nothing is too trivial.

There are two basic types of firewalls and both perform the same functions. One is the hardware of the other is software. A hardware firewall has been downloaded to your router if you use one, as you may or may not have a software firewall installed. To continue our analogy of the house, a firewall is like building a wall and door of your house and give the guard at the door of the instructions on who to let in and out. While this gives great protection, not everything is what it takes. Someone may know a way around or under the wall, or even be able to force the guard to let them in.

You yourself may unwittingly allow someone in. This can happen by simply opening an email or just surf the net. Spyware, viruses, trojans and the like are increasingly popular in the methods of fooling you and your guards. Emails can come from a trusted friend containing a dangerous virus without their knowledge. This is where the next layer of protection comes in the anti-virus software.

The anti-virus software is a large category these days. Often these packages come as "suites" including a firewall and Spyware scanner. While most of these programs are very effective in their promised tasks, it is unwise to be lulled into a false sense of security for them. It is simply one layer in what should be a plan for multiple levels of protection for you and your team. One last important note about anti-virus software is to make sure it is updated regularly. The new threats come everyday to check its updates manually to ensure that happened.

Back to our analogy of the house, now we have all our windows, doors and other entry ways locked and fully updated. We have a wall around our house with a guard at the door and have software scanning everything that comes past the door. Sounds good, but there is a security hole last thing we need to deal with you.

A large percentage of infections are caused by the computer user themselves. The Internet is a constantly changing place that requires users to be informed about their use. I am not suggesting that you need to be a computer expert to simply read your email. However, I am suggesting that you take time to educate yourself on some of the dangers that arise every day, and precautions to take to avoid them.

In short, the computer is a powerful machine connected to one of the greatest things ever invented the Internet. This vast resource can be dangerous if not properly prepared and informed. Regular software updates, a good firewall, anti-virus software and a little education are the basics in computer security. Having and understanding these basics will make your computer more secure, safer and more enjoyable.
