Introduction
In 1991 "Practical Unix Security" was released and became an instant hit in the Information Security community. Back then in the post Morris worm era, there was a need for an informative guide, describing the security techniques for the UNIX operating system. Five years after the initial release, the Internet started to evolve quickly, so the book received a revamp as "Practical Unix and Internet Security". As it can be seen from the title, the publication covered a broader range of topics and once again found its place on a number of bookshelves around the globe. Another six or seven years passed by and security of both the Unix based operating systems and Internet in general changed considerably. Both the authors and the publisher saw the need for a bigger update to the book, so O'Reilly presented us with "Practical Unix Security 3rd Edition".
