Microsoft included a firewall in Windows XP to keep you safe from hackers while you cruise the Internet. How do you know that the Internet Connection Firewall is on? Go to the Control Panel and double-click the Network Connections icon. In the dial-up, DSL, or cable connection dialog that appears, check the Status column. If your firewall is on, it should say Firewalled. You can turn the firewall off with the check box, but unless you are going to add a third-party firewall for heightened security, it's best to leave it on.
Now that you know that your firewall is on, how do you know that it's doing its job? Test it with ShieldsUp, the free testing service sponsored by Gibson Research. According to our tests, XP's Internet Connection Firewall kept the computer in full stealth mode. Hackers could not break in and couldn't even see the computer online.

In XP, the Documents And Settings folder holds all user information, including configuration settings, favorites, and cookies. The Documents And Settings\Username\Cookies folder is where XP stashes cookies. How do you control the number of cookies you allow on your system? Click Start > Control Panel > Network And Internet Connections > Internet Options. Click the Privacy tab, then use the slider bar to modify your cookie settings. For instance, you can block cookies from sites that use personal identification without your consent. To increase your security, try out the other privacy settings in this dialog. The lowest level is Accept All Cookies while the highest is Block All Cookies, with low, medium, medium-high, and high settings in between. (An explanation of each appears as you move between settings.) Keep in mind that rejecting cookies may limit your actions on some Web sites.
While these security tools help keep your information safe from malicious users while you're on the Internet, Windows XP comes with additional tools for folks who share a computer. See Multiuser features within this article for more information.

When you use Windows XP, you belong to one of two groups: Administrators or Users. Administrators are all-powerful: if you have a so-called Admin account, you can make systemwide changes and change other users' accounts. While this power is a boon to the ego, it's also dangerous. If, for example, you encounter a virus, a Trojan horse, or a worm while you're logged on as Administrator, you could wreck all the accounts on your entire system. Log in as User, on the other hand, and any damage you cause will be less extensive, because ordinary users are prevented from making systemwide changes. A word to the wise: Do your everyday computing as a regular user and log on as Administrator only when it's absolutely necessary, such as when adding a new user or changing security settings. To sign on as User, use the Run As command: just right-click a shortcut and select Run As. As long as you know the username and password, you can sign on as another user.
