Creating and Managing Intelligent
Application Gateway Endpoint Policies
Microsoft??™s Intelligent Application Gateway 2007 (IAG) is a hardware appliance that
integrates technology purchased from Whale Communications in the summer of 2006
and the vendor??™s own Internet Security and Acceleration (ISA) Server.
IAG 2007 is ideal for IT managers, network administrators, and information security
professionals who are concerned about the security, performance, manageability, and
cost of network operations.
IAG 2007 combines an SSL VPN with endpoint security checks and fi rewall features,
enabling the creation of policy-based remote access controls to a network and its
individual applications. This ???access portal??? features three levels of policy-based traffi c
fi ltering at both the packet and application layers. End users access the platform through
their Web browsers with communications being protected via SSL encryption; and
policies can be defi ned specifying which users and/or machines are enabled access to
which network resources.
Access to the IAG appliance from remote locations is accomplished with any Web
browser. Microsoft lists multiple browsers as compatible; however, Internet Explorer has
components that enable specifi c features of the gateway that are available only as ActiveX
controls. Therefore, full functionality requires a Windows and Internet Explorer based
endpoint.
