This allows for the creation of peruser
or per-group firewall policy rules, enabling administrators to restrict access to
specific applications, networks, and other resources on a per-user basis. This information
is also logged in ISA, so that per-user reports on such things as per-user website
usage and security audits can be performed.
. WinSock Application Support??”The Firewall client works directly with the
Windows Sockets (Winsock) drivers to provide for rich support for applications
written to take advantage of WinSock functionality.
. Complex Protocol Support??”The Firewall client is capable of handling complex
protocol definitions in ISA Server, including those that make use of secondary protocols
as part of their definition.
TIP
As with any piece of software, the Firewall client requires occasional updates on all the
systems. For example, the 2006 version of the software includes a newer version of
the Firewall client than ISA 2004 included. For security and functionality reasons, it is
therefore important to keep the software up to date, using software such as Systems
Management Server (SMS) 2003 or other software management software.
