WCF REST Service Denial of Service Defence

Question

I have created a WCF REST Search Service, and now want to know how to implement Denial of Service Defence to limit the number of request.

Answer 1

Assuming your REST API is publicly reachable over the Internet, you should implement your safeguards the same way you would defend against a DOS attack against a web site. There's really not going to be much difference in the approach, given that your RESTful service is (very likely) implemented using HTTP/HTTPS as the underlying application transport.
