Hi,

I'm about to implement an RESTful API to our website (based on WCF data services, but that probably does not matter).

All data offered via this API belongs to certain users of my server, so I need to make sure only those users have access to my resources. For this reason, all requests have to be performed with a login/password combination as part of the request.

What's the recommended approach for preventing brute force attacks in this scenario?

I was thinking of logging failed requests denied due to wrong credentials and ignoring requests originating from the same IP after a certain threshold of failed requests has been exceeded. Is this the standard approach, or am I a missing something important?

Thanks,

Adrian
