When surfing the Internet you probably take your anonymity 
for granted, most of us do. 
Tapping phones, listening to confidential conversations, 
reading others' e-mail messages seems like something that 
only happens in spy movies to "other" people. 
However, you probably don't realize just how much 
information about yourself has the potential to get 
transmitted across the Internet every time you go online. 
Every computer connected to the Internet has "ports" that 
allow it to connect. A "port" doesn't mean you have a 
physical hole or opening in your computer's case or 
hardware, but it does mean you have openings through which 
information passes back and forth between your computer and 
the Internet. 
Depending on the type of connection (dial up, LAN, cable, 
DSL), you may have several openings for potential mischief 
by hackers, malicious code or viruses. 
Computers with dedicated connections rate the most at risk. 
If someone or something gets into one of these ports and 
into your computer, they can potentially watch everything 
you do and see all the data you enter, including social 
security numbers and credit card information. 
The easiest way to defeat this problem involves using a 
firewall. Firewalls, simple and inexpensive software 
available at virtually any office supply or computer store, 
block the most common ports hackers use to enter your 
computer. 
Firewalls also help you detect and block unauthorized 
transmission of information from your computer to the 
Internet. This adds a significant measure of protection if 
you get infected with a Trojan Horse virus that tries to 
"phone home" to the hacker with your sensitive information. 
If you'd like to test your connection for vulnerability to 
attack, log on to http://security1.norton.com and run the 
various diagnostics. I would strongly advise anyone 
connected to the Internet through DSL or cable to get and 
use a firewall to protect against unauthorized access. 
Infected with "Spyware?" 
Previously we talked about unauthorized access to your 
computer. But a growing problem online with people watching 
you and your activities involves using programs you 
willingly place on your computer. 
Commonly called "Spyware," this refers to any program that 
transmits information about you to someone else without you 
knowing exactly what gets sent. The main purpose of Spyware 
involves tracking your surfing habits so advertisers know 
which targeted ads to send you. 
Most Spyware basically comes onto your computer bundled 
with other software applications, as a standalone program, 
or as modification to the HTML on a web page. 
Regardless of how you get it, you need to understand 
exactly what information gets transmitted about you so you 
can decide whether to keep or uninstall the software. Plain 
and simple, these Spyware programs can potentially reveal 
extremely sensitive information about you and your online 
habits.

computer currently carries any, log on to www.lavasoft.de
