Abstract: Embodiments include computing devices, apparatus, and methods implemented by the apparatus for time varying address space layout randomization. The apparatus may launch first plurality of versions of a system service and assign a random virtual address space layout to each of the first plurality of versions of the system service. The apparatus may receive a first request to execute the system service from a first application. The apparatus may randomly select a first version of the system service from the first plurality of versions of the system service, and execute the system service using data of the first version of the system service.
