“Information security” is an all encompassing term used to describe computer based security techniques for both home PC users and business networks, particularly in relation to web threats to data systems and personal information. Over the relatively brief history of the internet, information security has taken many different incarnations, and even today is an ever changing and multi faceted system of safeguards against constantly evolving web based threats.

But the important question is this: How do I protect the information stored and sent through my home and business computers?  Essentially, information security is a three step process, all of which can be utilized by any computer user.

First, there is prevention.  Before even connection to the Internet, a PC user must already have security software installed on his or her computer.  Many Web based threats are designed to detect and prey upon computers that have no security software in place; thus, your computer may be detected within seconds after connecting to the Internet.

Many computers, particularly personal PCs designed for home use, come with security software already installed, but many users choose not to rely on this software.  After all, many computer making companies have special deals with information security software companies to use their programs exclusively.  In many cases, the software already installed on the computer is not the best product out there.  Sometimes, pre-installed security software is, in fact, completely obsolete and inferior to even the average computer software.

Thus, it’s important to rigorously research the information security software you choose to use. Don’t just stick with the default, unless you know for a fact that the software already on your computer is the best available to suit your needs.

The second step is detection. The reason that so many viruses and spyware programs thrive is that they often go months or even years without being detected. After all, no information security software is infallible; makers of spyware, spam, and viruses are always coming up with new and innovate techniques for infecting your computer. Thus, antivirus and antispyware programs can do a great deal to detect threats, but there is always a danger of something getting through.

If you notice your computer acting funny — if it freezes, crashes, or if important programs start to behave in odd ways — then your computer may be infected with something. If this is the case, you’ll want to detect the program early so that you can eradicate it from your system.

The most important thing is not to wait. If you suspect that your computer is infected with a virus or spyware, then it’s best to address the problem immediately. Many viruses don’t work all at once; rather, they cause slow degeneration. Sometimes, it can take up to a year for a computer to crash after infection.

Finally, if your PC is infected, you want to make sure you have programs in place that can eradicate the threat. The best information security software is overwhelmingly proficient at this step. As soon as an invader is detected in the system, these programs can isolate it from the hard drive, essentially rendering it incapable of doing damage. After that, the program can find the best way to completely erase it, and prevent it from returning.

Also, it’s important that your information security software be made by a company that keeps an ongoing, constantly updating database of current threats. After all, viruses and spyware are always changing, and your company needs to take care of you beyond the point of selling you software. Many companies have periodic subscriptions for this service. Make sure you keep you subscription up to date.
