The world's most business-critical transactions run on Unix machines, which means the machines running those transactions attract evildoers. Furthermore, a lot of those machines have Internet connections, which means it's always possible that
some nefarious remote user will find a way in. The third edition of Practical Unix & Internet Security contains--to an even greater extent than its favorably reputed ancestors--an enormous amount of accumulated wisdom about how to protect
Internet-connected Unix machines from intrusion and other forms of attack. This book is fat with practical advice on specific defensive measures (to defeat known attacks) and generally wise policies (to head off as-yet-undiscovered ones).
authors' approach to Unix security is holistic and clever; they devote as much space to security philosophy as to advice about closing TCP ports and disabling unnecessary services. They also recognize that lots of Unix machines are development platforms,
and make many recommendations to consider as you design software. It's rare that you read a page in this carefully compiled book that does not impart some obscure nugget of knowledge, or remind you to implement some important policy. Plus, the authors
have a style that reminds their readers that computing is supposed to be about intellectual exercise and fun, an attitude that's absent from too much of the information technology industry lately. Read this book if you use any flavor of Unix in any
mission-critical situation. --David Wall
Topics covered: Security risks (and ways to limit them) under Linux, Solaris, Mac OS X, and FreeBSD. Coverage ranges from responsible system administration (including selection of usernames and logins) to
intrusion detection, break-in forensics, and log analysis.
When Practical Unix Security was first published more than a decade ago, it became an instant classic. Crammed with information about host security, it saved many a Unix
system administrator from disaster. The second edition added much-needed Internet security coverage and doubled the size of the original volume. The third edition is a comprehensive update of this very popular book - a companion for the Unix/Linux system
administrator who needs to secure his or her organization's system, networks, and web presence in an increasingly hostile world. Focusing on the four most popular Unix variants today--Solaris, Mac OS X, Linux, and FreeBSD--this book contains new
information on PAM (Pluggable Authentication Modules), LDAP, SMB/Samba, anti-theft technologies, embedded systems, wireless and laptop issues, forensics, intrusion detection, chroot jails, telephone scanners and firewalls, virtual and cryptographic
filesystems, WebNFS, kernel security levels, outsourcing, legal issues, new Internet protocols and cryptographic algorithms, and much more. Packed with 1000 pages of helpful text, scripts, checklists, tips, and warnings, Practical Unix & Internet
Security remains the definitive reference for Unix administrators and anyone who cares about protecting their systems and data from today's threats.
