In addition to a new array of firewall functionality, ISA
Server 2006 provides robust Virtual Private Networking
(VPN) support and enhanced web-caching capabilities, all
within a simplified management interface. It also provides
for a high degree of integration into an environment with
existing security infrastructure in place, providing for an
additional layer of security that could not have been
achieved otherwise.
This book gives an in-depth analysis of the ISA Server
product, with an emphasis on exploring ???best practice???
approaches that can be used when implementing an ISA
8 CHAPTER 1 Introducing ISA Server 2006
Server environment. These examples are gathered from real-world implementations and
lessons learned from the field with the product. Because a majority of ISA Server implementations
are established to complement??”rather than replace??”existing security infrastructure,
particular emphasis is placed on the information and tools necessary to
supplement these environments with ISA Server 2006. Third-party security tools, intrusion
detection techniques, and firewall and VPN products working in coexistence with ISA
Server 2006 are detailed throughout the chapters.
