Intrusion detection systems are increasingly recognized as a key weapon in the war against computer crime. In The Practical Intrusion Detection Handbook, one of the field's leading experts shows exactly how to use them to detect, deter, and respond to security threats. This is the only intrusion detection book to present practical advice for the entire lifecycle: choosing products, planning, deployment, operations, and beyond. Full of checklists and real-world case studies, The Practical Intrusion Detection Handbook demonstrates exactly how to integrate intrusion detection into a total strategy for protecting your information and e-commerce assets. Paul E. Proctor introduces each approach to intrusion detection, including host-based, network-based, and hybrid solutions; then offers practical selection criteria; and reviews the key factors associated with successful deployment. You'll watch today's best intrusion detection systems in action, through response, surveillance, damage assessment, and data forensics. Finally, Proctor addresses the future of intrusion detection -- from standards and interoperability to law and ethics.
