What Are the Security Implications of Using REST Vs. WebSocket APIs for Order Submission?

REST APIs typically require a new connection for each request, which can increase overhead but offers a clean, stateless interaction. WebSocket maintains a persistent, stateful connection, which is faster for continuous order updates but presents a larger attack surface if compromised.

Both require robust TLS/SSL encryption and HMAC-based request signing for authentication. The key risk for both is the secure management of API keys and preventing replay attacks.
