Among other things, apparatuses and techniques are described for managing security of devices in a vehicle using a security gateway. In one aspect, a circuit is coupled to a device in a vehicle, and manages communications between the device and entities external to the vehicle. The circuit receives, from an external entity, communication traffic for the device. The circuit determines, using a known security policy for the device, whether the communication traffic is valid communication traffic for the device. The circuit also determines, using a known device profile of the device, whether the communication traffic satisfies characteristics of the device profile. If the communication traffic is valid communication traffic for the device, and the communication traffic satisfies the characteristics of the device profile, the circuit forwards the communication traffic to the device.
