BROWSING PRIVACY AND SECURITY

Looking for multipurpose tools for protecting your privacy and security? The following three can help you surf anonymously, avoid trouble at wireless hot spots, and receive alerts about certain sites that may host malware designed to invade your privacy.

Tor

A surprising amount of information about you can be gathered as you surf the Web--including the operating system you use, the sites you've visited recently, your geographic location, and possibly your company (based on your IP address).

To keep these pieces of information private, try Tor, a free program that protects your anonymity as you surf. Tor takes all of your Internet communications, including instant messaging and other Internet applications, and sends them around a large network of "onion" routers that are Tor servers, making it impossible for sites or people to invade your privacy.

The Tor download includes other software that you need for maintaining your privacy--notably Privoxy, a proxy program. The programs work well together; and because the software self-configures, they are simple to use. Tor runs in your system tray. To become anonymous, right-click the icon and choose Start. From that point on, you'll be anonymous. To stop surfing anonymously, right-click again and choose Stop. You can even change your Tor identity for maximum cloaking.

Hotspot Shield

Some of the most nefarious online dangers arise when you're away from your home or office: Wi-Fi hacking and snooping. In a hotspot at a public location, a bad guy can set up a sniffer to snoop on all the data sent by everyone nearby. The snoop can see all of the information you send and receive over the Internet, including your user names and passwords.

Hotspot Shield sets up a virtual private network (VPN) for you and encrypts all of your data so that it can't be read. It works in much the same way as the VPNs that companies use for their remote employees.

Hotspot Shield is quite simple to install, set up, and use, with one caveat: During the installation process, you must make sure not to let the Dealio toolbar be installed. It's adware that has nothing to do with how the program works, so choosing not to install it won't have any adverse effects. When you first launch the program, your default browser will launch and display an ad. But you can close that window and continue to surf safely.
