Claim 7:
8. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:
responsive to detecting initiation of a boot sequence in a computing system of a vehicle, track characteristics of programs executing as part of the boot sequence by validating segments of the programs as the programs load;
determine whether the programs correspond with a program execution graph (PEG) by comparing the characteristics of the programs as the programs boot with the PEG; and
provide a response to thwart a malicious program when the boot sequence does not match the PEG,
wherein the PEG graphs relationships between the programs in the boot sequence including at least a sequence of function calls and an order in which the programs load, and wherein the PEG is pre-generated prior to the boot sequence.
