A brownfield security gateway is configured to support a trusted execution environment (TEE) that employs cryptographic and physical security—which forms a trusted cyber physical system—to protect sensitive transmissions on route to a controllable device. The gateway may be implemented with a System on Chip (SoC) that utilizes an application layer gateway to filter content within a transmission. When the application layer gateway authorizes the transmission, the transmission is forwarded to a trusted peripheral device that is configured with communication transport protocols, and the trusted peripheral device transfers the transmission to the controllable device. The trusted peripheral device and the controllable device are physically protected by, for example, protected distribution systems. Accordingly, the trusted peripheral device functions as a gateway between the SoC and the controllable device.

Accordingly, the trusted peripheral device functions as a gateway between the SoC and the controllable device.

The application is directed to a computer-implemented method and apparatus for provisioning an Internet of Things (IoT) device on an IoT network. The application is also directed to a method for managing access to functionality of an IoT device in a networked group.

Leveraging pre-existing groups for IoT device access

Runtime code hooking techniques are described in which a place holder instruction within a compiled module is used as an entry point to enable code hooking. A hook function to modify a target function is developed. At runtime, the target function to be modified is located. A place holder instruction within the target function is overwritten with instructions to cause execution of the hook function when the target function is called.
