Is Your ISP Spying On You?
Arcticsid asked the Answer Line forum if his ISP can "sit back…watch a screen, and see everything you are doing at any given time?"
Not quite, but it's frightening close. Your Internet service provider tracks what IP addresses you contact, which effectively means they know the web sites you're visiting. They can also read anything you send over the Internet that isn't encrypted. Whether they actually do that is an open question.
According to Dan Auerbach, a Staff Technologist for the Electronic Frontier Foundation, what they mostly collect is metadata--things like IP addresses and port numbers.
And how can you protect yourself?

If you're really paranoid, you might want to consider Tor, a free program.
