The first PC's were used for two primary purposes. For those who grew up using typewriters, the word processing ability of the PC was revolutionary. For others, the PC was a great place to play video games.

From those two applications, we have seen the entire world revolutionized by the way that the PC is used on a daily basis by millions of people. No office could function in the modern world without one as the financial records of major businesses are now stored on virtual files instead of paper.

Email has become the number one method of communication in the modern business world and the internet itself has made information universally available. With all of these advances of course, comes the problem of security. PC security is now more important than ever before simply because the value of the information that is at stake is now greater than ever before.

Internet security is a very important subset of overall pc security. When shopping or conducting business online, be sure to look for Secured Socket Layer (SSL) certification. This encryption software has become the standard for protecting credit card numbers and other data from prying eyes, including those of hackers.

Wifi, or wireless internet, has exploded in popularity recently. More than ever before, travelers are taking laptop computers on the road and connecting to the internet through Wifi hotspots. Sometimes charging a low fee, or in some places free, these Wifi hotspots allow us to communicate via computer from points around the world.

Many Wifi spots use WEP encryption technology to provide wireless computer security, but just as many do not. If you connect through a non-encrypted Wifi hotspot, it is possible that data you transmit could be seen by others in the area. Use discretion when transmitting sensitive data.

When thinking about PC security, hardware security is just as important as data computer security. Many computer users are careful to use pc security software and set their privacy settings to a high level, but never think about protecting the computer itself. Laptop computers are particularly vulnerable due to their portability, but desktop systems are not immune.

When traveling with your laptop, think about ways to keep the computer safe. A lockable case will deter thieves, but in many cases a thief will simply take the entire case to be opened at his or her leisure.

Instead, lock the laptop in an in-room safe whenever possible, and be especially vigilant about its protection in large common areas such as airports. GPS tracking is available for laptops and may be worth the expense if your computer is valuable or contains sensitive data.

When thinking about PC security, hardware security is just as important as data computer security. When considering what PC security systems you want to use, make sure that you at least consider these options.

Back up your data regularly and store the backups away from the computer. You will want to be able to re-create your files if the computer is stolen. If you have especially sensitive data, create more than one backup to be stored in separate locations.

A variety of PC security techniques should be employed in tandem. This will greatly increase your odds of keeping your data safe. Using your operating system's built-in system computer security features, third party PC security software and physical means of protecting your computer mean that your chances of data protection are quite high.

Be sure to regularly update both your operating system and your third party protective software as well.
