A method for operating an industrial PC (IPC) device, wherein the IPC device includes a general-purpose operating system (GPOS) section implemented to execute program code under the GPOS, and a real time operating system (RTOS) section implemented to execute program code adapted to real-time data processing under the RTOS, includes providing a wrapped application program based on an application program including binary code designed to be executed under the RTOS and a security policy; validating the wrapped application program according to the security policy by an RTOS process for obtaining a validated application program; transferring the binary code of the validated application program and a security element from the RTOS process to a GPOS process; establishing a secure communications channel between the GPOS process and the RTOS section using the security element; and executing the binary code of the validated application program by the GPOS process.
