Why This Chapter Matters

After you install and configure Microsoft Exchange Server 2003, your next task should be to implement security on Exchange Server 2003 servers. You need to prepare for and protect against virus attacks, secure mailboxes, implement digital signatures and encryption, configure firewalls, and set appropriate administrative permissions. You should also reduce the number of services that are running on the server, allowing only the services that are necessary to run Exchange Server 2003. Unnecessary services use resources and widen the attack target.

E-mail is possibly the most vulnerable sector of any organization's operation, and good security is essential.
