METHODS, SYSTEMS, AND COMPUTER PROGRAM PRODUCTS FOR IMPLEMENTING INTER-PROCESS INTEGRITY SERIALIZATION

A method, system, and computer program product for implementing inter-process integrity serialization services is provided. The method includes enabling process states including a must-stay-controlled (MSC) state and an extended must-stay-controlled (EMSC) state for an invoking process when it is determined that only programs designated as controlled, if any, have been loaded for the invoking process. The invoking process requests loading of a target program into temporary storage for performing a security service. Based upon a control indicator of the target program, the MSC state, and the EMSC state, the method includes controlling one or more activities within the temporary storage. The activities include loading the target program into the temporary storage, executing a main program in the temporary storage, and resetting the MSC state and the EMSC state across execution of the main program during the lifetime of the invoking process.
