I've used jMeter proxy to inspect SSL traffic coming from my iPhone, by installing the jMeter certificate on the iPhone and then configuring my wifi on the phone to use the jMeter proxy.
If I want to prevent this MITM sniffing for a particular website/server can I just enforce TLS 1.2 on the server?
Does TLS1.2 actually prevent this kind of MITM sniffing if it is enforced throughout?
