Publisher description
Designed for engineers and administrators, this book covers everything
needed to plan out and integrate a DMZ into a network for small, medium and
Enterprise networks. In most enterprises the perception is that a firewall
provides a hardened perimeter, but the security of internal networks and hosts
is usually very soft. In such an environment, a non-DMZ system that is offering
services to the Internet vreates the opportunity to leapfrog to other hosts in
the soft interior of your network. In this scenario your internal network is
fair game for any attacker who manages to penetrate your so-called hard
perimeter. The primary role of a DMZ is to mitigate risks associated with offering
services to untrusted clients. It accomplishes this by providing network-level
protection for a hosting environment, as well as segregating public hosting
facilities from the private network infrastructure. This small but crucial
segment of the network i the section exposed to the public Internet and is the
section exposed to the public Internet and is the msot difficult area on the
network to create and maintain both from an engineering standpoint and a
security standpoint. In this book, readers can learn how to make DMZs utilizing
the IT world's best of breed software and hardware products. Designed for engineers and administrators, this book covers everything
needed to plan out and integrate a DMZ into a network for small, medium and
Enterprise networks. In many enterprises the firewall provides a hardened
