Configuring gateway and network security
IoT systems consist of multiple gateways, networking protocols, and even physical mediums. Edge devices may connect to each other within a Wireless Sensor Network (WSN) using short-range protocols such as ZigBee and Z-Wave, while gateways connect to the cloud over IP connections using messaging frameworks, such as MQTT or REST. Securing an IoT system requires a comprehensive evaluation and lockdown of the gateways and networking components of the system.
Securing WSN
WSNs can consist of thousands or more low-power battery-operated sensors that communicate using protocols, such as ZigBee, Z-Wave, Bluetooth, NFC, or Thread. WSNs make use of gateways that can act as translation devices between the short-range RF protocols and IP-based protocols that communicate with the cloud. Security administrators must consider the secure configuration of the devices and protocols used within WSNs, as well as how to manage securely keys used within WSNs.
