Methods, systems, and devices for security configurations for zonal computing architecture are described. A zonal computing system in a vehicle may be associated with multiple zones. The zonal computing system may include devices (e.g., sensors, actuators) that interact with the vehicle or an environment associated with the vehicle. A memory system included in the zonal computing system may authenticate whether a device associated with a zone is a trusted device and enable or restrict communications with the device based on the authentication. For example, the zonal computing system may include a central processor that communicates with a remote server and the multiple zones and may include a gateway processor coupled with the central processor and the device and associated with the zone. Based on whether the device is trusted, the memory system may enable or restrict communications between the central processer and the device and routed through the gateway processor.
