Technical Details

what runs on :18187

The service is registered for both TCP and UDP, but ELA is normally encountered as a session-oriented TCP service on port 18187. An OPSEC client establishes the proprietary ELA session and normally uses Check Point's authentication and SSL-based protection; it is not a human-readable text protocol. The related OPSEC LEA log-export interface is commonly associated with TCP 18184, while exact availability and security settings depend on the Check Point release and enabled OPSEC applications.

security overview

Do not expose this port directly to the Internet. An accessible ELA endpoint may disclose security-event data and provide an attack surface for authentication and protocol weaknesses; restrict it to authorized monitoring or analysis hosts and require the deployment's OPSEC certificate and access controls.
