In this experiment, we will analyse both security frameworks and will propose a security baseline for multi-vendor infrastructures. The challenge to security that we are addressing in this project appears when decoupling the 5G network functions and applications from the infrastructure and accepting that different players construct parts of the network.  Our basic scenario will include requirements of critical Unmanned Aerial Vehicles (UAV) platform (as the Slice Tenant) hosted by the US partner Embry-Riddle Aeronautical University (EAU).
