Today's networks are vulnerable to a multitude of known attacks. The best hackers around, many of whom are now actively working to protect the network space they now call 'home' with millions of (less-sophisticated) users, have determined that the best way to protect the Internet as a whole is to "harden" the network pipes using various cryptographic implementations. This tutorial will cover some well-known and lesser-known host hacking techniques, hacker culture, and several promising methods for hardening the networks against all manner of terrorist and other attacks; specifically: building encrypted host-to-host transport pipes with IPSEC so that the hard-to-patrol side roads along the main "superhighway" backbones are difficult to gain access to; creating cryptographically secure authentication protocols for the Domain space with DNSSEC to prevent spoofing and spamming abuse; and storing critical cryptographic keying material on well-protected hardware devices such as smartcards, hardware tokens, etc. Dave Del Torto, Pretty Good Privacy, Inc.
