The success of an ISA Server implementation depends
largely on its design. ISA Server 2006 is a complex, capable
system that can assume multiple roles in the organization.
It is therefore important to first understand what the security
needs are, and then match those needs to the various
pieces of ISA Server functionality.
Because ISA can assume multiple roles, a proper ISA design
does not always fit cookie-cutter style roles. In fact, many
ISA server designs involve multiple ISA servers distributed
across multiple network locations. The need to provide for
network security has evolved to encompass both external
and internal traffic within an organization, and ISA Server
2006 provides the tools to perform these tasks.
This chapter focuses on the design factors that are involved
in an ISA Server 2006 deployment.
