When does the level of trust and reliability of data change during communication between IoT systems?

• when data is generated by a device inside a trusted network and travels to an untrusted network
• when data is generated by a device inside an untrusted network and stays in an untrusted network
• when data is generated by a device within a DMZ and stays within the DMZ
• when data is generated by a device inside a trusted network and stays within the network

Explanation: When referring to security, crossing a trust boundary means that the level of trust and reliability of data has changed. As data moves from a trusted network to an untrusted network, the security of the data changes.
