Explanation

To properly classify and gain visibility into Internet of Things (IoT) devices, a firewall can analyze DHCP traffic, as IoT devices frequently use DHCP for network connectivity. Why DHCP is the Correct Answer? IoT Devices Often Use DHCP for IP Assignment ? Most IoT devices (smart cameras, sensors, medical devices, industrial controllers) dynamically obtain IP addresses via DHCP. Firewalls can inspect DHCP requests to identify device types based on DHCP Option 55 (Parameter Request List) and Option 60 (Vendor Class Identifier). Enhances IoT Security with Granular Policies Palo Alto Networks IoT Security uses DHCP data to assign risk scores, enforce access control policies, and detect anomalies. Does Not Require Deep Packet Inspection Unlike RTP, RADIUS, or SSH, which focus on specific protocols for media streaming, authentication, and encryption, DHCP data is lightweight and easily analyzed.
