Chapter 22: ISA Server Deployment Planning and Design


Introduction

Planning your ISA Server installation before actually performing it is absolutely critical. As with any firewall, the amount of thought and analysis you put into your design will help optimize ISA performance and will minimize the chance of making a substantial error that will adversely affect your security or access schemes.

All traffic that moves between the Internet and your internal network should move through a firewall, which is your ISA server. It is the job of the bastion host to ensure that all packets sent to and received from the Internet are evaluated and assessed for their relevance and safety.

The ISA server is a firewall because it provides the demarcation point between a trusted and untrusted network. Moreover, the ISA server can provide DMZ services through additional network interfaces. Because of this, it is critical to make sure that the ISA server is set up as securely as possible.
