    have a look at systrace. you can block or log with pass arbitrary syscalls
    tied to program names.

    for reference, various people have looked at the idea of tracking syscall
    paths as a method to detect anomalies. systrace is currently stateless,
    but with some work it could be made stateful. its just hard to express a
    directed graph of syscalls.
    
    for reference, i did some syscall graphs on openbsd some months back. it
    should give you an idea of the rapid complexity you will find:

    systrace as it stands should be useful for you.
