Selecting an Intrusion Detection System
- Abstract
- Selecting an intrusion detection system (IDS) to protect your network is a decision that should not be made lightly, quickly, or without a firm understanding of the technology, options, or the potential impacts. The decision process can be divided into the following steps: identify the need, gain a general understanding of intrusion detection systems, gain a detailed understanding of the network, evaluate various IDS systems, and determine policy and procedures.
