A method of protecting software in a computer system includes defining a memory fractionation configuration for an application software program in the computer system, fractionating at least one page of the application software program into fractions according to the memory fractionation configuration, and running the application in such a manner that, at any particular point in time when the application is running, at least a first one of the fractions is stored in a manner that is not accessible from a user space or a kernel space of the computer system.

Memory fractionation software protection

Methods for reducing the impact of malware during a booting sequence for an interrupt driven computing device are disclosed. One or more parameters associated with an interrupt vector table (IVT) are manipulated to force the computing device into a clean state following a system level portion of the booting sequence. In another embodiment, occurring prior to the loading of an operating system or a call to a non-returnable main( ) function, one or more unused interrupt vectors in an IVT are replaced. A function filter is implemented for one or more interrupt vectors in the IVT to disallow unnecessary interrupt functions from being executed. One or more required interrupt vector functions are replaced with one or more corresponding custom vector functions. One or more memory locations are wiped if the one or more memory locations do not hold at least a portion of the IVT and/or the interrupt vector functions.
