Challenge #1: Performance Cost
The performance cost becomes increasingly larger in large-scale networks.
Solution
The separation of the policy database (PD) and the evaluator — the PD is stored on a central server and is referenced by evaluators installed on each individual router in the network.

Challenge #2: Encrypted Payload
In some cases, such as HTTPS, the payload of a data packet is encrypted and thus cannot be properly read without the key.
Solution
The system uses negative authorization, meaning that it only rejects packets which have indicators for data which the source device is not authorized for.

Challenge #3: Mobile IoT Devices
Many IoT devices, such as smartwatches, are mobile and thus are not exclusive to a single network.
Solution
The system can keep a record of when it loses connection with an IoT device. This at least accounts for the time during which the system cannot monitor the device.

Conclusion
The proposed model would best be used to secure the IoT devices within a stationary network to prevent hackers from illegally accessing valuable data.
