By extending DHCP traffic visibility further into your network, you can now discover and monitor even more devices than ever. IoT Security employs multiple methods to detect and monitor network activity and correlate it to individual devices. A particularly useful method is the examination of DHCP traffic, which allows IoT Security to associate dynamically assigned IP addresses with device MAC addresses and then add these devices to its inventory and track their network behavior. When it’s difficult to route DHCP traffic in certain areas of the network to or through a firewall, there can be gaps in the coverage that IoT Security provides. To improve visibility into DHCP traffic that otherwise wouldn't reach the firewall, you can configure DHCP servers to send the firewall their server logs as syslog messages. The firewall then forwards the logs through the logging service to IoT Security.
