Malicious Mobile Code

Malicious mobile code is a new term to describe all sorts of destructive programs: viruses, worms, Trojans, and rogue Internet content. Until fairly recently, experts worried mostly about computer viruses that spread only through executable files, not data files, and certainly not through email exchange. The Melissa virus and the Love Bug proved the experts wrong, attacking Windows computers when recipients did nothing more than open an email. Today, writing programs is easier than ever, and so is writing malicious code. The idea that someone could write malicious code and spread it to 60 million computers in a matter of hours is no longer a fantasy. The good news is that there are effective ways to thwart Windows malicious code attacks, and author Roger Grimes maps them out in Malicious Mobile Code: Virus Protection for Windows. His opening chapter on the history of malicious code and the multi-million dollar anti-virus industry sets the stage for a comprehensive rundown on today's viruses and the nuts and bolts of protecting a system from them. He ranges through the best ways to configure Windows for maximum protection, what a DOS virus can and can't do, what today's biggest threats are, and other important and frequently surprising information. For example, how many people know that joining a chat discussion can turn one's entire computer system into an open book? Malicious Mobile Code delivers the strategies, tips, and tricks to secure a system against attack. It covers:

The current state of the malicious code writing and cracker community How malicious code works, what types there are, and what it can and cannot do Common anti-virus defenses, including anti-virus software How malicious code affects the various Windows operating systems, and how to recognize, remove, and prevent it Macro viruses affecting MS Word, MS Excel, and VBScript Java applets and ActiveX controls Enterprise-wide malicious code protection Hoaxes The future of malicious mobile code and how to combat such code

These days, when it comes to protecting both home computers and company networks against malicious code, the stakes are higher than ever. Malicious Mobile Code is the essential guide for securing a system from catastrophic loss.
