Protection

Introduction

By its very nature, Exchange 2000 Server has a public face. You will be offering e-mail and other functionality to a large number of users. In many cases those users will not only be able to collaborate with other users in their own company, but also with others across the Internet. This high visibility makes it potentially more subject to attack than other services. You need to make sure that Exchange is well protected against potential attacks, including hacking attempts and viruses.

This chapter also examines disaster recovery scenarios. If you are to meet your service level agreements (SLAs) on availability, you must first ensure that your system is down as infrequently as possible. This is covered in Chapter 2, “Capacity and Availability Manage- ment,” but you must also make sure that if you do suffer downtime, it is kept to the bare minimum required to restore service. Disaster recovery procedures for Exchange 2000 are detailed in this chapter.

Chapter Start Point

At the start of this chapter, you should be familiar with basic security concepts and differ- ent types of backup and restore hardware.

Chapter End Point

By the end of this chapter, you should be aware of appropriate measures to take when guarding against hacker attacks and e-mail bound viruses. You will also be aware of disaster recovery procedures in the event of a failure.
