McAfee Firewall McAfee Firewall’s Intrusion Detection System Unlike other intrusion detection tools, McAfee Firewall’s powerful Intrusion Detection System (IDS) is simple to configure and activate. Instead of requiring users to learn and understand a complex set of attacks to build their own defense lines against intrusions, McAfee Firewall’s development team created a tool that, when activated with the click of a button, detects common attack types and suspicious activity.
McAfee Firewall Common attacks recognized by IDS The following table lists attacks recognized by McAfee Firewall’s IDS, a description of each attack, and the risk factor assigned to each attack. Attack Description Risk Factor 1234 Also known as the Flushot attack, an attacker sends an oversize ping packet that networking software could not handle. Usually, computers hang or slows down. If a total lockup occurs, unsaved data may be lost.
McAfee Firewall Attack Description Risk Factor Newtear A Denial of Service (DoS) attack that usually causes computers with a Windows NT-based operating system to crash. Although the attack is not usually harmful to the computer itself, data from running applications will most certainly be lost. High Oshare A Denial of Service (DoS) attack caused by sending a unique packet structure to your computer.
McAfee Firewall Attack UDP Flood Description A remote denial of service attack designed to flood the target machine with more data than it can process, thereby preventing legitimate connections from being established. Risk Factor High Machine is inaccessible via TCP/IP. Occurs when machine is put to sleep and then awakened. Make sure that “Load Only When Needed” is not checked in the TCP/IP control panel.

McAfee Internet Security’s Shared Features McAfee Shredder Securely delete files using McAfee Shredder When you save a file in Windows, it is stored in multiple pieces (in clusters made up of multiple sectors) on the disk. Windows also saves a road map, or index, that points to these clusters in two copies of the FAT (File Allocation Table). The FAT contains the directions to all the pieces of your files, so that applications can find them again later.
McAfee Internet Security’s Shared Features McAfee Shredder allows you to shred files on your PC’s Recycle Bin, Temporary Internet, as well as Web site history folder. You can also specify the number of shredding passes (1-99) and can now have the option to shred an entire drive.

Internet Security and Privacy B This chapter provides some background information that will help you understand Internet security and privacy threats, and discusses strategies for using McAfee Internet Security to protect yourself and your computer. Networks and the Internet A computer network links individual computers together so they can share data and resources.
Internet Security and Privacy Why packets? Why go through all this trouble, breaking data down into packets? The answer lies in the origins of TCP/IP. Like the Internet itself, it is a product of the Cold War. The United States Department of Defense originally developed the Internet. It was designed to ensure secure communications, even with multiple communications network failures anticipated in the event of a nuclear war.
Internet Security and Privacy About Privacy and Security on the Web Before the advent of the Web, Internet security usually posed a problem only for system administrators trying to keep meddlesome hackers away from their systems. When the Web arrived, the popularity of the Internet skyrocketed.
Internet Security and Privacy Snooping and Sniffing Since its inception, the Internet has been (and largely remains) an open network. Openness means that information on the Internet travels without any special security: Anyone who can monitor network traffic can intercept it. This sort of monitoring is called “sniffing,” and is easy to perform using “sniffers.” Sniffers are programs (or hardware devices) designed to monitor data traveling over a network.
Internet Security and Privacy When you visit an SSL-secured site, the latest versions of Netscape Communicator and Microsoft Internet Explorer use a visual cue to tell you that the site is secure. For more information, see How can I tell if a Web site is secure? TIP McAfee Internet Security’s Security Check lets you know if your Web browser is up-to-date. The latest browser versions usually offer an enhanced degree of security.
Internet Security and Privacy Certificates are Microsoft technologies designed to guarantee a person’s identity and Web site security. Personal certificates verify that you are who you claim to be. Web site certificates verify that a Web site is secure and what it claims to be (so Web sites can’t falsify their identity). When you open a Web site that has a certificate, Internet Explorer checks if the certificate is correct. If the certificate is not OK, Internet Explorer warns you.
Internet Security and Privacy Security on the Web One of the most exciting Web developments is the evolution of downloadable, executable programs. Java and ActiveX are two tools that help developers create programs that can “live” inside Web pages, and use your Web browser to automatically run over the Internet. Java allows Web pages to host small programs called “applets.” When Java-enabled browsers access a Web page containing Java, they automatically download and run the applets they find on the page.
Internet Security and Privacy Computer Viruses and the Web A computer virus is a small computer program that automatically replicates itself and spreads from one computer to another. Viruses may infect programs, your hard drive, and even some document files that employ macros. Viruses do not infect data files, but they can create problems that prevent you from accessing your data. Viruses are not accidents—they are always created by computer programmers.
Internet Security and Privacy n Macro viruses: Macro viruses are contained in document files, such as Microsoft Word or Excel files. These files can contain macros that can automate your work—but macros can also be written to do damage to your PC. Macro viruses are activated when you open an infected document file. n A final word should be said about hoax “viruses,” which are not viruses in the strictest sense of the term.
Internet Security and Privacy A virus might be hidden in the next file you download, or on a diskette you borrow —even diskettes purchased at a store. Downloaded shareware is also a source of infection. Although Java and ActiveX are not, strictly speaking, viruses (i.e., it can’t spread and replicate), they can still harm your PC. McAfee Internet Security’s default settings allow it to monitor all Java and ActiveX activity on your PC, and warn you before something potentially dangerous occurs.

Your McAfee Internet Security To-do List C After you finish installing McAfee Internet Security, and you have completed the preliminary setup using the Configuration Assistant, you will want to create and customize all of your user profiles. The purpose of this section is to guide you through the customization process.
Your McAfee Internet Security To-do List Conversely, cookies can record “what you did” on a particular Web site. For example, you visit one of the major search engine’s Web site and shop for an automobile. You revisit the same Web site a few days later and shop for an automobile again. The following week, you turn on your computer and go directly the same Web site. This time you’re looking for the local weather forecast. As the page loads into memory, there are ads for autos all over the screen.
Your McAfee Internet Security To-do List n Improve your Internet browsing experience by preventing ads and pop-up windows from displaying. n Shield younger family members from distasteful or undesirable content. Users of the Internet, at all age levels can exposed to inappropriate Web site content. A simple typographical error in the text box of your favorite search engine could return graphic gore, rather than cartoons; or pornography, rather than recipes.
Your McAfee Internet Security To-do List Virus Detection and Prevention Tips Although far from harmless, most viruses that infect your personal computer or laptop will not destroy data, play pranks, or render your computer unusable. Even the comparatively rare viruses that do carry a destructive payload usually produce their nasty effects in response to a trigger event. In most cases, unless you actually see evidence of a payload that has activated, you will have time to deal with the infection properly.
Your McAfee Internet Security To-do List n Update your anti-virus software regularly. These updates should be at the least the product's virus signature files (DATs). You may also need to update the scanning engine as well. n Back up your files on a regular basis. If a virus destroys your files, at least you can replace them with your back-up copy. You should store your backup copy in a separate location from your work files, one that is preferably not on your computer.
Your McAfee Internet Security To-do List n If you allow your computer to run 24 hours per day, then configure your Firewall to block communication while you are away from the desk. n Check for an update your software frequently, and configure it to notify you if there is an update available. n Review your activity logs periodically. If the logs display suspicious activity, or frequent violations, investigate the activity.
