Question

i read about 2 WS* protocols , WS-TRUST and WS-FED. but i am confused about real time scenario how to use these protocols . can anyone let me know in which scenarios i can use WS-TRUST and WS-FED ? it would be very helpful if someone can tell which is best among these 2 protocols for securing a REST service and a normal.ASPX page.

Answer 1

WS-Federation is for web applications (e.g. ASP.NET WebForms or MVC) WS-Trust is for SOAP-based web services (e.g. WCF)

for HTTP services you have to look into OAuth2.
