All security relevant system calls are extended by security enforcement code. This code calls the central decision component, which in turn calls all active decision modules (the different modules implementing different security models) and generates a combined final decision. This decision is then enforced by the system call extensions. | All security relevant system calls are extended by security enforcement code.
