If you have e-mail, you have spam—that annoying electronic junk mail that jams your inbox, sometimes makes you blush, and takes a lot of the fun out of your online experience. Spam wastes thousands of hours and costs you, the recipient of the stuff you don’t want, thousands of dollars in increased costs that your Internet service provider eventually passes along to you. In fact, a European survey in 2001 revealed that spam costs about $9.4 billion each year!

Spammers spam because they’re not paying for it, you are. The good news is, you can fight back, and Fighting Spam For Dummies tells you how. Find out

This book is a clear and informative introduction to cryptography and data protection--subjects of considerable social and political importance. It explains what algorithms do, how they are used, the risks associated with using them, and why governments should be concerned. Important areas are highlighted, such as Stream Ciphers, block ciphers, public key algorithms, digital signatures, and applications such as e-commerce. This book highlights the explosive impact of cryptography on modern society, with, for example, the evolution of the internet and the introduction of more sophisticated banking methods.

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.
