Internet & TCP/IP Network Security

Here is the step-by-step guide to setting up and using firewall security systems-as well as other products-that UNIX programmers have sorely needed. It not only describes what a firewall can do, but also, importantly, what it cannot do. Practically and authoritative, the book delivers details on how to secure internal networks from Internet intrusion... how to customize firewalls and network configuration files to suit specific security needs... and how to configure and use the controversial SATAN software, as well as security tools available via Anonymous FTP. In addition, it sheds light on emerging technologies such as Kerberos (a primary standard for authenticating identities developed at MIT to develop its own network).
