Summary : Passive Host Characterization is technology similar to IDS systems, but with several distinctions. The basic idea is to deploy sensors around your network to passively monitor traffic. Rather than looking for signatures, you’re going to focus on rules that collect data from the observed traffic. That data is then aggregated, reduced, and stored in databases. Via data-mining you can then see patterns in your network useful for applications such as host monitoring, content filtering, penetration testing, patch management, or detecting bots.
