Synopsis

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.Practical Unix & Internet Security consists of six parts:

• Computer security basics: introduction to security problems and solutions, Unix history and lineage, and the importance of security policies as a basic element of system security.
• Security building blocks: fundamentals of Unix passwords, users, groups, the Unix filesystem, cryptography, physical security, and personnel security.
• Network security: a detailed look at modem and dialup security, TCP/IP, securing individual network services, Sun's RPC, various host and network authentication systems (e.g., NIS, NIS+, and Kerberos), NFS and other filesystems, and the importance of secure programming.
• Secure operations: keeping up to date in today's changing security world, backups, defending against attacks, performing integrity management, and auditing.
• Handling security incidents: discovering a break-in, dealing with programmed threats and denial of service attacks, and legal aspects of computer security.
• Appendixes: a comprehensive security checklist and a detailed bibliography of paper and electronic references for further reading and research.

Packed with 1000 pages of helpful text, scripts, checklists, tips, and warnings, this third edition remains the definitive reference for Unix administrators and anyone who cares about protecting their systems and data from today's threats.

About this title

Review

The third edition of Practical UNIX & Internet Security contains--to an even greater extent than its favourably received predecessors--an enormous amount of accumulated wisdom about how to protect Internet-connected UNIX machines from intrusion and other forms of attack. 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. 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).

The 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 recognise 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. What's more, 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 type 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 a selection of usernames and logins) to intrusion detection, break-in forensics and log analysis. --Robert Lawton, Amazon.com

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
