Detailing Deployment Strategies with ISA Server 2006
What makes ISA Server stand out as a product is its versatility and capability to play the
part of multiple roles in an environment. In addition to the capability to be deployed as a
fully functional Application-layer firewall, ISA can also provide web caching, Virtual
Private Network support, reverse proxy, and combinations of any of them. It is subsequently
important to understand all the potential deployment scenarios for ISA when
considering the product for deployment.
Deploying ISA Server 2006 as an Advanced Application-Layer
Inspection Firewall
ISA Server 2006 was designed as a full-function firewall that provides for the type of functionality
expected out of any other firewall device. At a base level, ISA enables you to
block Internet traffic from using a specific port, such as the RPC or FTP ports, to access
internal resources. This type of filtering, done by traditional firewalls as well, provides for
filtering of Internet Protocol (IP) traffic at the Network layer (Layer 3). The difference
between ISA and most other firewalls, however, comes with its capabilities to filter IP
traffic at the more complex Application layer (Layer 7).
