When Practical UNIX Security was first published in 1991, it became an instant classic. Crammed with information about host security, it saved many a UNIX system administrator and user from disaster.This second edition is a complete rewrite of the original book. It's packed with twice the pages and offers even more practical information for UNIX users and administrators. It covers features of many types of UNIX systems, including SunOS, Solaris, BSDI, AIX, HP-UX, Digital UNIX, Linux, and others. The first edition was practical, entertaining, and full of useful scripts, tips, and warnings. This edition is all those things -- and more.If you are a UNIX system administrator or user in this security-conscious age, you need this book. It's a practical guide that spells out, in readable and entertaining language, the threats, the system vulnerabilities, and the countermeasures you can adopt to protect your UNIX system, network, and Internet connection. It's complete -- covering both host and network security -- and doesn't require that you be a programmer or a UNIX guru to use it.Practical UNIX & Internet Security describes the issues, approaches, and methods for implementing security measures. It covers UNIX basics, the details of security, the ways that intruders can get into your system, and the ways you can detect them, clean up after them, and even prosecute them if they do get in. Filled with practical scripts, tricks, and warnings,Practical UNIX & Internet Security tells you everything you need to know to make your UNIX system as secure as it possible can be.Contents include:

Part I: Computer Security Basics. Introduction and security policies.
Part II: User Responsibilities. Users and their passwords, groups, the superuser, the UNIX filesystem, and cryptography.
Part III: System Administrator Responsibilities. Backups, defending accounts, integrity checking, log files, programmed threats, physical security, and personnel security.
Part IV: Network and Internet Security: telephone security, UUCP, TCP/IP networks, TCP/IP services, WWW, RPC, NIS, NIS+, Kerberos, and NFS.
Part V: Advanced Topics: firewalls, wrappers, proxies, and secure programming.
Part VI: Handling Security Incidents: discovering a breakin, U.S. law, and trust.
VII: Appendixes. UNIX system security checklist, important files, UNIX processes, paper and electronic sources, security organizations, and table of IP services.

Best for beginners

Reviewed in the United States on August 1, 2003

Verified Purchase

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.

Only really understandable if you have unix/linux knowledge going in

Reviewed in the United States on December 19, 2013

Verified Purchase

This book may be very useful for people who have a strong working knowledge of Unix or Linux. I would recommend learning one of these operating systems before purchasing the book because it's practically unintelligible without that base of knowledge.

I bought it for a class and stopped reading it after the third week of school because I was getting nothing out of it. One can learn security concepts without learning Unix.

I recommend this book only if you have a good background in Unix or Linux. Otherwise, it will likely end up a paperweight.

Good review book of things I have known for a long time. But, it should be geared more toward large enterprise security tools like BoKS, PowerBroker, TripWire, etc.

Some useful information, but outdated, fair coverage of essentials.

Reviewed in the United Kingdom on August 22, 2018

Verified Purchase

As above, but very U.S. -centric. From the off (Page 1) we're told about how many americans know of x or y. Phrases like "Congressional action" re-inforce the impression of a standard U.S. world-blindness. It's offputting to read such and kicks off the annoyance meter for the rest of it. The rest of the world understand software and security just as well as you do, Messers authors.

A pity because even today, MacOS, penguinistas and BSD users can get some fairly good refreshers from this mega-tome.
Top quote: "...vet your (job) applicants with a lie-detector test (if legal)".
Right.

UNIX security basics described clearly and understandably

Reviewed in the United Kingdom on January 2, 2016

I am preparing for an IT security audit of enterprise UNIX systems. I had limited understanding of UNIX prior to reading this book. However I feel more confident now - the book provides an understandable description of the basic concepts, goes into sufficient detail and compares the different versions at an acceptable level. This book helped me loads in preparing for the audit, recommended for the whole team to read.

A great book! Despite the time that has passed since the release - still valid! Describes important issues related to the security of unix systems and the Internet. Mandatory reading for network and unix system administrators! I would recommend!
