O'REILLY PUBLISHES GUIDE TO INTERNET FIREWALLS
New Book Describes Theory and Practice of Key Computer Security Technology

September 20, 1995--SEBASTOPOL, CA--O'Reilly & Associates has released
"Building Internet Firewalls," a practical guide to protecting computer
systems from the growing threats to Internet security.

Determined Internet hackers and computer criminals can wreak havoc if they
break into computer systems that are connected to the Internet. Firewalls
are an important security tool for responding to this threat--they keep
damage on one part of the network (e.g., eavesdropping, a worm program,
file damage) from spreading to the rest of the network. A hardware and/or
software solution that restricts access from an internal network to the
Internet (and vice versa), a firewall may also be used to separate two or
more parts of a local network (for example, protecting finance from R&D).
Without firewalls, network security problems can rage out of control.

"Building Internet Firewalls" describes a variety of firewall approaches
and architectures. It discusses Internet threats, the benefits of
firewalls, overall security strategies, and a summary of Internet services
and their security risks. In addition, the book thoroughly covers the
technical aspects of firewall design and maintenance, including how to
protect the bastion host in a firewall configuration, how to build
proxying and packet filtering firewalls, and how to configure Internet
services to operate with a firewall. Its appendices include a resource
summary, a directory of how to find firewall toolkits and other
security-related tools, and a detailed summary providing TCP/IP background
information.

More than a million computer systems are now connected to the Internet.
Over 100 million email messages are exchanged each day, along with
countless files, documents, and images. For businesses that are striving
to be safe on the Net, "Building Internet Firewalls" offers a
comprehensive guide to the theory and practice of creating effective
firewalls.
