. End-to-end secure web publishing capabilities??”The web publishing rules
improved in ISA Server 2006 allow for end-to-end securing of Secure Sockets Layer
(SSL) encrypted web traffic from client to ISA Server, and then back to web server.
When the traffic is decrypted at the ISA Server, it can be inspected for viruses and
HTTP exploits. The traffic is then re-encrypted before being sent to the web server.
. RADIUS and SecurID authentication support??”In addition to supporting Active
Directory authentication, ISA Server 2006 now supports authentication natively
against a RADIUS or RSA SecurID authentication infrastructure. This enables an ISA
Server to be a member of a workgroup, as opposed to a domain member.
. Stateful inspection for VPN connections??”In this version of ISA Server, all traffic
that passes through ISA is inspected for Application-layer attacks (stateful inspection).
This includes VPN connections as well.
. VPN quarantine control features??”ISA Server 2006 introduces the capability to
provide granular control to VPN clients by enabling administrators to restrict new
VPN connections to a separate quarantine network.
