Editorial Reviews

Amazon.com Review

Practical Unix & Internet Security is on its second edition, and its maturity shows. To call this highly readable book comprehensive is an understatement. The breadth is vast, from fundamentals (definitions of computer security; the history of Unix) and commonsense but little-observed security basics (making backups; physical and personnel security; buggy software) to modern software (NFS, WWW, firewalls) and the handling of security incidents. The section on users and passwords alone is 21 pages long--and worth every page. Useful appendices include a Unix security checklist, a list of emergency response organizations, and many references to electronic and paper resources.

The Internet covers too much and moves too quickly for any book to cover every security aspect of every piece of software, but this book comes close. More importantly, it gives you an exceptional grounding in the fundamental issues of security and teaches the right questions to ask--something that will stay with you long after today's software is obsolete.

Review

"It's almost impossible to criticize such a venerable work as this, and there can be little doubt that backed up by online resources, this will form a solid foundation and reference work for years to come." - Martin Howse, LinuxUser & Developer, Issue 30 "If you know nothing about Linux security, and only have time for one book, you should start with Practical Unix and Internet Security." - Charlie Stross, Linux Format, September --This text refers to an alternate Paperback edition.

4.0 out of 5 stars Recommended with reservations for students & hobbyists only, April 25, 1998

By	Nikolai N Bezroukov "kievite" (Budd Lake, NJ) - See all my reviews

Somewhat outdated -- two years old in a very dynamic field, Rootkit is not even mentioned, Bugtraq mentioned only in supplement, etc. Far from being practical and can be used only as an introductory text in Unix security. Not recommended for Internet security (superficial and incomplete). Good style --  Simson Garfinkel of The UNIX-Haters Handbook fame  is a really talented journalist (but now only a journalist, see his interview with Amazon.com).  The main problem with the book is that instead of relying on tools as any Unix author should, the authors use a cookbook/reference approach giving recipes about improving security. References to important RFCs, FAQ and CERT advisories are absent. For example RFC1244 (now superseded by RTC2196) is not mentioned in index(and probably in the text as well) although Ch.2 and Ch.24 mirror its content. No attempts were made to explain what tools can be used for checking/fixing particular class of problems or to present a bigger picture in which the flaw exists. Typesetting is very primitive. Although one of the authors is a (former) programmer judging by just the book content it is difficult to believe that he is able to spell PERL :-). The book is not updated enough to compete with newer books on Internet Security. For corporate users possible alternatives are combinations of one book on Unix security (for example, Unix System Security by David A. Curry) and one book on Internet security (for example Actually Useful Internet Security Techniques by Larry J. Hughes). The last is recommended as an alternative for readers who cannot afford two books. Often books written by a specialist in particular areas can be a better deal than books from security folks. For example TCP/IP Network Administration by Craig Hunt contains a lot more information about how properly configure TCP/IP than this book and in Ch.12 has a very decent overview of security in just 40 pages.

3.0 out of 5 stars Best for beginners, August 1, 2003

By	G. Hoeppner (Lansing, MI) - See all my reviews (REAL NAME)

This review is from: Practical Unix & Internet Security, 3rd Edition (Paperback)

As a Linux administrator, I ordered this book hoping to find out how hackers typically gain access to systems and neat little tricks for locking down my system, as well as detecting and dealing with intruders. While Practical Unix & Internet Security did cover these topics, it covered little I didn't already know.

Significant time is spent explaining how unix-based systems work. The book covers things such as file systems, partition structure, file ownership/permissions, users and groups, inodes, ssh, backups, etc. Each command, utility, procedure or feature is detailed over several pages followed by an explanation of what you should be doing with said topic.

There are also a few real-world examples here and there; stories most of us have heard before, like the admin who had . in his path.

Unlike many computer books, this one is well written and an easy read, and it's certainly a lot more friendly than some unix geek's advice which consists of RTFM.

I think this book would be great for someone who has a very basic understanding of unix-based systems but has never administrated one before, but for those of us who've already had some experience running unix there's probably not anything new here for you.

5.0 out of 5 stars Little Giant. . . Vade Mecum, March 1, 2003

By	Marco De Vivo "mata-hackers" (Miami, Florida United States) - See all my reviews (REAL NAME)

This review is from: Practical Unix & Internet Security, 3rd Edition (Paperback)

The second edition of this book was my security vade mecum for the last 8 years. For what I can foresee, this third edition, will play the same role for (at least) the next three years.

When you are required as an security expert, several tasks are usually to be faced:

New scenarios to analyze?, checklists to recommend?, good firewall architectures to suggest?, logs to watch? (and so on). Don't worry, with the only help of this Garfinkel, Spafford and Schwartz 'little giant' book, you are done.

Excellent book. A Must for security people.
