Definition

Collecting network communication protocol metadata and identifying statistical outliers.

How it works

How it works Network protocol metadata is first collected and processed in real-time or post-facto. Metadata may include packet header information or information about a session (ex. time between requests/responses). Metadata is then grouped based on shared characteristics and those groups are compared to each other. If particular metadata differs significantly from other data, an alert is generated, identifying the network event as anomalous. Anomalous activity may indicate unauthorized activity. Considerations Metadata collection on enterprises can yield large data sets. Storage, indexing, querying, and aging should be considered prior to implementation.
