Rate Limiting and Abuse Prevention
Protect your WebSocket server from floods, spam, and resource exhaustion using connection limits, message rate limiting, and payload validation.
Persistent Connections Invite Abuse
Unlike stateless HTTP, a WebSocket holds an open connection. A single malicious client can flood messages, open thousands of connections, or send huge payloads, exhausting your server.
Limit Connections Per Client
Cap how many simultaneous connections one IP or user may open to prevent connection-exhaustion attacks.
const perIp = new Map();
if ((perIp.get(ip) || 0) >= 5) return socket.destroy();
perIp.set(ip, (perIp.get(ip) || 0) + 1);All lessons in this course
