ABSTRACT:
A computer program product is for use with a computer system that executes methods. Scope permission setting computer readable program code includes access request reception computer readable program code for receiving a request from a first method, executing at a first security level, to be dynamically empowered to access methods to be executed at a second security level, wherein the second security level is higher than the first security level. Dynamic capability activation computer readable program code is responsive to the access request reception code and includes static capability determination computer readable program code for determining if the first method is statically capable of accessing security methods generally and dynamic capability indication computer readable program code, responsive to the static capability determination code, for indicating in the activation record for the first method that the first method has been dynamically empowered to access security methods generally. Dynamic capability determination computer readable code, responsive to a request by the first method to access a particular security method, is for determining whether the activation record created for the first method includes an indication that the first method is capable of accessing security methods generally.
