A method for providing an interprocess interaction in an electronic control unit having an operating system defining a kernel space, the method comprising: intercepting, by the kernel of the operating system , a request for an interprocess communication between a first application and a second application of the electronic control unit ; requesting a verdict, from an access control component of the operating system , with respect to granting access for the requested interprocess communication between the first application and the second application of the electronic control unit ; generating, by the access control component , the verdict for the requested interprocess communication based on a security policy and selectively allowing, by the kernel of the operating system , the requested interprocess communication between the first application and the second application based on the generated verdict, said method being characterized in that the security policy includes a list containing a plurality of data elements and wherein each of the plurality of data elements indicates at least an identifier of a client application, an identifier of a service application and an identifier of a service allowed to be performed by the service application and in that the access control component generates an affirmative verdict in response to finding a data element in the list matching the identifier of the first application, the identifier of the second application and the identifier of the service and wherein the access control component generates a negative verdict in response to not finding a data element in the list matching the identifier of the first application, the identifier of the second application and the identifier of the service. intercepting, by the kernel of the operating system , a request for an interprocess communication between a first application and a second application of the electronic control unit ; requesting a verdict, from an access control component of the operating system , with respect to granting access for the requested interprocess communication between the first application and the second application of the electronic control unit ; generating, by the access control component , the verdict for the requested interprocess communication based on a security policy and selectively allowing, by the kernel of the operating system , the requested interprocess communication between the first application and the second application based on the generated verdict, said method being characterized in that the security policy includes a list containing a plurality of data elements and wherein each of the plurality of data elements indicates at least an identifier of a client application, an identifier of a service application and an identifier of a service allowed to be performed by the service application and in that the access control component generates an affirmative verdict in response to finding a data element in the list matching the identifier of the first application, the identifier of the second application and the identifier of the service and wherein the access control component generates a negative verdict in response to not finding a data element in the list matching the identifier of the first application, the identifier of the second application and the identifier of the service. <EOS>
