This book is the long awaited second edition of a classic book in basic computer security. It is an introduction to the field, not a technical reference. If you need details on a particular aspect of computer security, you should refer to another more specialized book. Since does not show the table of contents, I review this book in reference to its table of contents:Part I, SECURITY FOR TODAYChapter 1, IntroductionIntroduces computer security: what it is and why it's important. It summarizes the threats to computers and the information stored on them, and it introduces the different types of computer security. It notes that if you ignore computer security you could not only be a crime victim but an unwitting partner in crime.Chapter 2, Some Security HistoryDescribes how we got to where we are today. It summarizes key events in the history of computer security, discusses some of the government standards and programs involved with computer security, and introduces the concept of computer databases and the preservation of privacy.Part II, COMPUTER SECURITYChapter 3, Computer System Security and Access ControlsIntroduces computer system security and describes how it controls access to systems and data.Chapter 4, Viruses and Other WildlifeExplores viruses, worms, Trojans, and other types of malicious code. The financial effects of malicious programs are discussed first, including that of wasted time. Next it equates viruses and public health - in that once your computer is infected others can be too using your computer as a jumping off point.

It still surprises me how many of my information technology colleagues still have no clue when it comes to computer security. This particular book is one I'd feel really good about when it comes to a recommendation to get them up to speed on the subject...

Pretty much all the significant issues surrounding computer and technology security these days is covered in sufficient detail to allow for a functional understanding of the topics. For instance, the chapter on viruses would allow even the most clueless techie to grasp the problems. The authors distinguish between viruses, worms, trojan horses, bombs, and other various nasty surprises. The history is valuable to understand how we got into this condition, and by the end of the chapter you'll know what you need to do to start to combat the problem. From there, you can dive into the more technical details of any one of the areas that pertain to your particular situation.
