Identity theft is becoming one of the most common white collar crimes. Since most of our lives are intertwined with technology, we are all at risk of having our personal information stolen. This doesn’t mean that you should abandon the amazing advances in computing, but you should no how to protect yourself.
There are two general things that you can do to greatly reduce your risk of having your personal information stolen; protect your computer from intrusion and identifying and avoiding risk or scams.
Protecting your computer is the first step. Every time your computer connects to the internet or your home wireless network, you are introducing a risk. Someone who in not physically at your house is interacting with your computer in some way. 99.999% of the time this is simply a web server send page to you at your request. There is the chance that someone has created a hidden connection and is browsing through your files though. The first way to close the security whole to the world is with a “firewall”. A firewall is simply a specialized program that accepts incoming network requests, analyzes them, and allows them to pass through or discards them based on predetermined rules. If you are using Windows XP, Service Pack 2 as a greatly improved firewall that we recommend for basic protection. For a more advanced firewall, see our Security Tools page. If you are using a wireless network you need to take a few steps to protect yourself. Please refer to your “wireless networks” on our Tips Page.
The second way to protect your self is an intuitive process. In general, don’t give your information out to illegitimate or insecure sources. Easier said than done. The most common way to gather information today is called PHISHing. This is when a fraudulent source poses as a reputable business like a bank and requests that you give them information. Commonly it is emails that look very professional and say that you need to update your account information. A link will take you to a look-a-like website where you enter all your account information and proof, now they know everything about you and your account. Click here for more information on PHISHing.
