Prelude Manager is the main program of the Prelude Hybrid IDS suite. It is a multithreaded server which handles connections from the Prelude sensors. It is able to register local or remote sensors, let the operator configure them remotely, receive alerts, and store alerts in a database or any format supported by reporting plugins, thus providing centralized logging and analysis. It also provides relaying capabilities for failover and replication. The IDMEF standard is used for alert representation. Support for filtering plugins allows you to hook in different places in the Manager to define custom criteria for alert relaying and logging.
