Generally, it is up to you to protect yourself, your PC, and your valuable information from the continual threats and annoyances streaming over the Internet This chapter is intended to raise your awareness of the dark side of the Internet and introduce you to the tools that can help you avoid some of these bumps along the Internet highway
The Firewall
A large number of people and organizations are continually searching the Internet for unprotected PCs so they can hijack and use them to distribute pornography, send spam, or carry out some other illicit activity Moreover, an estimated 5 percent of all transactions on the Internet are fraudulent or an attempt at theft Unfortunately, we are forced by these Internet realities to build a wall around our PCs and home networks, an electronic wall called a firewall A firewall is software that sets up a protective wall between a particular PC or network, the private side, and the rest of cyberspace, the public side Having a firewall is a good starting point for the implementation of a personal computing plan for Internet security DSL, cable-modem, and satellite connections are always on and, therefore, pose greater risks of unauthorized access for individual PCs and home networks Commercial firewall products, such as Symantec s Norton Internet Security Professional (see Figure 13-1) and McAfee Security s Personal Firewall Plus or Internet Security Suite, offer excellent protection from external invasion into your system Windows XP has a built-in firewall To enable the Windows firewall, enter enable firewall in the Windows Help and Support search box and follow the directions If you have broadband, your modem/router, which usually is provided by the ISP, has a built-in firewall, as well The modem/router, a communications device that sits between your PC (or your home network) and the broadband link, is discussed further in 18, Building a Home Network If your Internet access is through a modem/router, its built-in firewall is preferable to the Windows firewall A firewall is a system that enforces access control policy between your PC (or a home network) and the Internet Firewalls differ widely in methods and levels of sophistication, but all of them have essentially two tasks, to block traffic and to permit traffic A firewall s access control policy can be set up to screen electronic traffic in both directions such that it restricts unwanted access to a PC or home network and can block certain types of outgoing communications Most firewalls automatically block unsolicited attempts at communication from the public side of the wall They
