Linux consistently turns up high in the list of popular Internet servers, whether it's for the Web, anonymous FTP, or general services like DNS and routing mail. But security is uppermost on the mind of anyone providing such a service. Any server experiences casual probe attempts dozens of time a day, and serious break-in attempts with some frequency as well. As the cost of broadband and other high-speed Internet connectivity has gone down, and its availability has increased, more Linux users are providing or considering providing Internet services such as HTTP, Anonymous FTP, etc., to the world at large. At the same time, some important, powerful, and popular Open Source tools have emerged and rapidly matured–some of which rival expensive commercial equivalents–making Linux a particularly appropriate platform for providing secure Internet services. Building Secure Servers with Linux will help you master the principles of reliable system and network security by combining practical advice with a firm knowledge of the technical tools needed to ensure security.

The Linux Network Administrator's Guide, Third Edition dispenses all the practical advice you need to join a network. Along with some hardware considerations, this highly acclaimed guide takes an in-depth look at all of the essential networking software that comes with the operating system–including basic infrastructure (TCP/IP, wireless networking, firewalling) and the most popular services on Linux systems. But as the follow-up to a classic, the third edition of the Linux Network Administrator's Guide does more than just spruce up the basics.

Compiled by Red Hat Software, Inc., the company that has assembled the most popular x86 installation of Linux, this command reference is massive, authoritative, and as complete as any reference can be.

In 1,500 pages of tiny print, this heavy-duty tome documents every command, utility, file system, library function, and administration tool in the operating system. Linux also features a detailed kernel reference guide and a good index. And if the print size bothers you, the entire contents of the book are included on the companion CD-ROM, along with the Unix version of the Adobe Acrobat reader. In Acrobat, you can adjust the font size to something more readable. If you're running a Linux system and acting as your own system administrator, Linux: Complete Command Reference is an indispensable reference.

We humans are born with an inner drive to explore the nature of our surroundings. As young men, both Kevin Mitnick and I were intensely curious about the world and eager to prove ourselves. We were rewarded often in our attempts to learn new things, solve puzzles, and win at games. But at the same time, the world around us taught us rules of behavior that constrained our inner urge toward free exploration. For our boldest scientists and technological entrepreneurs, as well as for people like Kevin Mitnick, following this inner urge offers the greatest thrills, letting us accomplish things that others believe cannot be done.

The Art of Deception shows how vulnerable we all are - government, business, and each of us personally - to the intrusions of the social engineer. In this security-conscious era, we spend huge sums on technology to protect our computer networks and data.

By following this resource, corporations can go wireless and still protect mission-critical data. Top corporate security consultant, Stewart Miller covers security for Windows, Linux, Macs, Palms, and other PDAs, and shows how to prevent breaches caused by weak encryption protocols. This work review security approaches for the different standards currently competing for the U.S. market. It addresses data compromise, unauthorized access, and denial of service - all critical to WLAN users. It covers the 802.11 IEEE standard in regards to security, performance, and throughput. It also discusses encryption and privacy through the WEP (Wired Equivalent Privacy) protocol.

FreeBSD and OpenBSD are increasingly gaining traction in educational institutions, non-profits, and corporations worldwide because they provide significant security advantages over Linux. Although a lot can be said for the robustness, clean organization, and stability of the BSD operating systems, security is one of the main reasons system administrators use these two platforms. There are plenty of books to help you get a FreeBSD or OpenBSD system off the ground, and all of them touch on security to some extent, usually dedicating a chapter to the subject. But, as security is commonly named as the key concern for today's system administrators, a single chapter on the subject can't provide the depth of information you need to keep your systems secure. FreeBSD and OpenBSD are rife with security "building blocks" that you can put to use, and Mastering FreeBSD and OpenBSD Security shows you how. Both operating systems have kernel options and filesystem features that go well beyond traditional Unix permissions and controls. This power and flexibility is valuable, but the colossal range of possibilities need to be tackled one step at a time.
