Résumé

The definitive guide to understanding, selecting, and deploying intrusion detection in the enterprise!

Product selection, planning, and operations
Filled with real-life cases and stories of intrusion detection systems in action
Covers host-based and network-based intrusion detection

Foreword by Dorothy Denning, author of Cryptography and Data Security and Information Warfare and Security

Technical Edit by Ira Winkler, author of Corporate Espionage

In The Practical Intrusion Detection Handbook, one of the field's leading experts shows exactly how to detect, deter, and respond to security threats using intrusion detection systems. Using real-world case studies and practical checklists, Paul E. Proctor shows what intrusion detection software can achieve, and how to integrate it into a comprehensive strategy for protecting information and e-commerce assets. No other guide to intrusion detection offers all this:

Practical coverage of host-based, network-based, and hybrid solutions
Detailed selection criteria and sample RFPs
Key factors associated with successful deployment
Intrusion detection in action: response, surveillance, damage assessment, data forensics, and beyond
Six myths of intrusion detection — and the realities

Whether you're a senior IT decision-maker, system administrator, or infosecurity specialist, intrusion detection is a key weapon in your security arsenal. Now, there's a start-to-finish guide to making the most of it: The Practical Intrusion Detection Handbook by Paul E. Proctor.

"Intrusion detection has gone from a theoretical concept to a practical solution, from a research dream to a major product area, from an idea worthy of study to a key element of the national plan for cyber defense. . . Nobody brought that about more than Paul Proctor. . . Paul brings his considerable knowledge and experience with commercial intrusion detection products to this first-of-a-kind book."
