Security Administrator Tool for Analyzing Networks.
SATAN was written because we realized that computer systems are becoming more and more dependent on the network, and at the same becoming more and more vulnerable to attack via that same network.

For each type or problem found, SATAN offers a tutorial that explains the problem and what its impact could be. The tutorial also explains what can be done about the problem: correct an error in a configuration file, install a bugfix from the vendor, use other means to restrict access, or simply disable service.

SATAN collects information that is available to everyone on with access to the network. With a properly-configured firewall in place, that should be near-zero information for outsiders.

Breaking into your site.
Goal: Improving security by finding the vulnerabilities and fixing them. The uebercracker (Nietzsche reference).

We will illustrate that even seemingly harmless network services can become valuable tools in the search for weak points of a system, even when these services are operating exactly as they are intended to.

Another tool available for sniffing network packets
  1. Using a Honeypot to watch and surveil intruders could land you in jail or a big lawsuit???

  2. Pretty Good Privacy, aka via TLA as PGP.

  3. Shortcut to Cryptography. More links that you could ever need.
