An API Behavioral Security (ABS ) cluster consists of stateless ABS nodes communicating with a MongoDB replica set.
Each ABS node connects to the MongoDB cluster to obtain cluster configuration information that describes peer nodes. ABS nodes themselves do not communicate with each other; they periodically send heartbeats to MongoDB with status information. Each ABS node exposes:
- REST APIs for log streaming between ABS and API Security Enforcer (ASE)
- REST APIs between ABS and management applications which fetch metrics, anomalies, attack types, backend error, blocked connections, flow control, and cluster status.
An ABS cluster is depicted in the following diagram.
