Internet Attacks More Serious and Technically Complex, says author of "Building Internet Firewalls"
Sebastopol, CA--In the five years since the first edition of this classic
book--O'Reilly's Building Internet Firewalls--was published,
Internet use has exploded, and e-commerce has become a daily part of
business and personal life. The commercial world has rushed headlong into
doing business on the Web, often without integrating sound security
technologies and policies into their products and methods. The security
risks-and the need to protect both business and personal data-have never
Internet security threats include password attacks and the exploiting of
known security holes, which have been around since the early days of
networking. Other threats, like password sniffers, IP forgery, and various
types of hijacking and replay attacks, are newer. And still others, like
the distributed denial of service attacks that crippled Yahoo, E-Bay, and
other major e-commerce sites in early 2000, come from today's headlines.
"The attacks on Internet-connected systems we are seeing today are more
serious and more technically complex than those in the past," says
Elizabeth D. Zwicky, co-author of
Firewalls. "To keep those attacks from compromising our systems,
we all need all the help we can get."
Firewalls are a very effective way to protect your system from most
Internet security threats and are a critical component of today's computer
networks. Firewalls in networks keep damage on one part of the network
(e.g., eavesdropping, a worm program, file damage) from spreading to the
rest of the network. Without firewalls, network security problems can rage
out of control, dragging more and more systems down.
Like the first edition of the highly respected and best-selling Building
Internet Firewalls, the
second edition is a practical and detailed guide to
building firewalls on the Internet. It provides step-by-step explanations
of how to design and install firewalls, and how to configure Internet
services to work with a firewall. The second edition is much expanded. It
covers Linux and Windows NT, as well as Unix platforms. It describes a
variety of firewall technologies (packet filtering, proxying, network
address translation, virtual private networks) as well as architectures
(e.g., screening routers, dual-homed hosts, screened hosts, screened
subnets, perimeter networks, internal firewalls).
The book also contains a new set of chapters describing the issues involved
in a variety of new Internet services and protocols through a firewall. It
covers email and news; Web services and scripting languages (e.g., HTTP,
services (e.g., NFS, Samba); remote access services (e.g., Telnet, the BSD
"r" commands, SSH, BackOffice 2000); real-time conferencing services (e.g.,
ICQ, talk); naming and directory services (e.g.,DNS, NetBT, the Windows
Browser); authentication and auditing services (e.g., PAM, Kerberos,
RADIUS); administrative services (e.g., syslog, SNMP, SMS, RIP and other
routing protocols, and ping and other network diagnostics); intermediary
protocols (e.g., RPC, SMB, CORBA, IIOP); and database protocols (e.g.,
ODBC, JDBC, and protocols for Oracle, Sybase, and Microsoft SQL Server).
Building Internet Firewalls, Second Edition features a
complete list of resources, including the location of many publicly
available firewall construction tools.
