Computer Security

For those worried about identity theft and how to combat it, there is help out there. Unfortunately, a lot of it comes in the form of legalistic sounding reports and explanations that can leave most consumers more confused afterward. Luckily, for those who want to use their computers as a line of defense, there are plenty of commercially available products to help.

In this case, internet users can use the same tool to protect themselves that puts them in the most danger in the first place. Ironically, some programs out there can be both a source of defense and a threat. What some people use to track their personal information, others can use to steal it.

Basics

When it comes to protecting a computer from intrusions and attempts to steal personal information, there are many types of tools, just as there are many ways for hackers to attack a computer. Not all attacks are aimed at stealing personal data to be used for identity theft, but just about all the malicious software in the world can be adapted for that purpose. These range from viruses and spyware to direct intrusions aimed at taking over a computer and turning it into a "zombie," a computer employed for illegal activity.

There are two basic forms of computer defense that no one can do without these days. They are virus scanning software and a personal firewall. Virus detection programs have been deemed essential for many years, but are even more so today. With "always on" broadband internet connections firewalls have moved out of the realm of the corporate world and into the home. Firewalls monitor attempts by remote computers to access the home computer and block both incoming and outgoing communications as per the user's specifications.

Security Companies

There are many cyber security firms out in the world that specialize in providing such protections. Two other big names are Symantec and McAfee. Both these companies market an array of programs aimed at protecting individuals against identity theft. Some block attempts at theft, while others seek to cover or erase the "trail" left from internet surfing and online financial activity.

These two big name companies and others also serve as watchdogs alerting the public to new scams and security flaws that are found in popular operating systems and internet browsers. They also provide regular updates to their software as new threats are identified and investigated. Some smaller companies sell add-ons to popular software offerings that target specific threats, such as identity theft.
