can I walk behind security between the two terminals and how long will it take?
There is no secure path.
A to C you just walk through the public area and have passport control and security at C.
Z to C you take the train and have transfer security at C.
The FRA MCT of 45 minutes would be cutting it fine normally. Things are little messy right now so hopefully you have longer than that...
