Understanding and implementing ISA 2004 as an application firewall
ISA Server 2004 (ISA firewall) includes a number of technologies that provide enhanced security performance for corporate network infrastructures. The unique combination of security and functionality is highlighted by the application filters included with the ISA firewall right out of the box. It is an important fact to realize that the RPC (Remote Procedure Call) protocol is used by many Microsoft networked applications, but that most of IT personnel, including network and firewall administrators, do not understand how the RPC protocols works. They donít understand what potential problems are generated by the RPC protocol, and most importantly, they donít know how to protect infrastructure servers. Typical network and firewall administrators just think that RPC is not secure and donít even consider the fact that RPC access can be made secure, and this article will show you how to secure it.
