Abstract:  For those still running Exchange 5.5, the end of Microsoft support on December 31, 2005, has the potential to leave these customers open to security vulnerabilities. In order to ensure a successful migration, it is integral that these security weaknesses be addressed while migrating to Exchange Server 2003.

This white paper, written by one of the industry's leading e-mail security authorities, Lee Benjamin, outlines solutions that can be implemented now that will protect Exchange 5.5 and continue to provide best-practice security during and after the migration to Exchange Server 2003. Read about Microsoft's Internet Security and Acceleration Server (ISA) 2004 that can be used to protect all versions of Exchange. A defense-in-depth architecture is suggested, with ISA positioned behind a perimeter firewall and in front of the Exchange Servers. In addition, NS Appliances are introduced as a cost-efficient way to implement ISA 2004.
