Secure your computer network with SSH! With transparent, strong encryption, reliable public-key authentication, and a highly configurable client/server architecture, SSH (Secure Shell) is a popular, robust, TCP/IP-based solution to many network security and privacy concerns. It supports secure remote logins, secure file transfer between computers, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. Best of all, SSH is free, with feature-filled commercial versions available as well.SSH: The Secure Shell: The Definitive Guide covers the Secure Shell in detail for both system administrators and end users. It demystifies the SSH man pages and includes thorough coverage of:
<ul>
<li> SSH1, SSH2, OpenSSH, and F-Secure SSH for Unix, plus Windows and Macintosh products: the basics, the internals, and complex applications.</li>
<li> Configuring SSH servers and clients, both system-wide and per user, with recommended settings to maximize security.</li>
<li> Advanced key management using agents, agent forwarding, and forced commands.</li>
<li> Forwarding (tunneling) of TCP and X11 applications in depth, even in the presence of firewalls and network address translation (NAT).</li>
<li> Undocumented behaviors of popular SSH implementations.</li>
<li> Installing and maintaining SSH systems.</li>
</ul>Whether you're communicating on a small LAN or across the Internet, SSH can ship your data from "here" to "there" efficiently and securely. So throw away those insecure .rhosts and hosts.equiv files, move up to SSH, and make your network a safe place to live and work.

Computer security is an ongoing process, a relentless contest between system administrators and intruders. A good administrator needs to stay one step ahead of any adversaries, which often involves a continuing process of education. If you're grounded in the basics of security, however, you won't necessarily want a complete treatise on the subject each time you pick up a book. Sometimes you want to get straight to the point. That's exactly what the new Linux Security Cookbook does. Rather than provide a total security solution for Linux computers, the authors present a series of easy-to-follow recipes-short, focused pieces of code that administrators can use to improve security and perform common tasks securely. The Linux Security Cookbook includes real solutions to a wide range of targeted problems, such as sending encrypted email within Emacs, restricting access to network services at particular times of day, firewalling a webserver, preventing Ip spoofing, setting up key-based Ssh authentication, and much more. With over 150 ready-to-use scripts and configuration files, this unique book helps administrators secure their systems without having to look up specific syntax. The book begins with recipes devised to establish a secure system, then moves on to secure day-to-day practices, and concludes with techniques to help your system stay secure. Some of the "recipes" you'll find in this book are: Controlling access to your system from firewalls down to individual services, using iptables, ipchains, xinetd, inetd, and more Monitoring your network with tcpdump, dsniff, netstat, and other tools Protecting network connections with Secure Shell (Ssh) and stunnel Safeguarding email sessions with Secure Sockets Layer (Ssl) Encrypting files and email messages with GnuPg Probing your own security with password crackers, nmap, and handy scripts This cookbook's proven techniques are derived from hard-won experience.

Operating Systems

Are you serious about network security? Then check out Ssh, the Secure Shell, which provides key-based authentication and transparent encryption for your network connections. It's reliable, robust, and reasonably easy to use, and both free and commercial implementations are widely available for most operating systems. While it doesn't solve every privacy and security problem, Ssh eliminates several of them very effectively. Everything you want to know about Ssh is in our second edition of Ssh, The Secure Shell: The Definitive Guide. This updated book thoroughly covers the latest Ssh-2 protocol for system administrators and end users interested in using this increasingly popular Tcp/Ip-based solution. How does it work? Whenever data is sent to the network, Ssh automatically encrypts it. When data reaches its intended recipient, Ssh decrypts it. The result is "transparent" encryption-users can work normally, unaware that their communications are already encrypted. Ssh supports secure file transfer between computers, secure remote logins, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. With Ssh, users can freely navigate the Internet, and system administrators can secure their networks or perform remote administration. Written for a wide, technical audience, Ssh, The Secure Shell: The Definitive Guide covers several implementations of Ssh for different operating systems and computing environments. Whether you're an individual running Linux machines at home, a corporate network administrator with thousands of users, or a Pc/Mac owner who just wants a secure way to telnet or transfer files between machines, our indispensable guide has you covered. It starts with simple installation and use of Ssh, and works its way to in-depth case studies on large, sensitive computer networks.No matter where or how you're shipping information, Ssh, The Secure Shell: The Definitive
