1. A method for implementing inter-process integrity serialization services, comprising: 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 invoicing process requesting loading of a target program into temporary storage for performing a security service; and based upon a control indicator of the target program, the MSC state, and the EMSC state, controlling one or more activities within the temporary storage, comprising: the loading of the target program into the temporary storage, the temporary storage accessible to the invoicing process; execution of a main program in the temporary storage; and reset of the MSC state and the EMSC state across execution of the main program during the lifetime of the invoicing process; wherein programs are designated as controlled upon validation under security guidelines.
