Who should attend: Network and system managers, security managers, and auditors. This tutorial assumes some knowledge of TCP/IP networking and client/server computing.

What can intrusion detection do for you? Intrusion-detection systems are designed to alert network managers to the presence of unusual or possibly hostile events within the network. Once you've found traces of a hacker, what should you do? What kind of tools can you deploy to determine what happened, how they got in, and how to keep them out? This tutorial provides a highly technical overview of the state of intrusion-detection software and the types of products that are available, as well as the basic principles to apply in building your own intrusion-detection alarms. Methods of recording events during an intrusion are also discussed.
