JSON WCF Security
2 answers
WCF is just a framework that makes communication easier, it doesn't make anything secure by itself.
JSON is just a great way to transfer data, for example when posting to a web page, since it can be more compact than xml, and javascript can parse JSON faster than xml, since JSON is built for javascript.
If you have sensitive information, you can either encrypt that specific data or just use SSL connections, but this can impact performance.
