Beginning in 2000, and ramping up from 2004, corporate and home users have been subjected to increasing numbers of "client-side" attacks. No longer are services offered by computers the only means of attack. Now, the applications upon which users rely, like Web browsers, e-mail clients, chat programs, and so on, are the targets. Instead of an intruder attacking the Web server running on a company's Internet-facing server, the intruder attacks the Web browser of an internal user surfing intentionally or accidentally to a malicious Web site. **This book is all about preventing, detecting, and mitigating breaches that result from e-mailed Trojans, spyware, malicious Web sites, etc. It's about dealing with all the problems exploits cause, since these days the most devastating attacks are accidentally launched by employees inside a company.
