Reference Monitor Vs. System Call Wrapper RRS feed

  • General discussion

  • Hi,

    I am trying to clearly distinguish both terms according to their properties and uses.

    I know that they work the same way by interposing system calls.

    However, I am still confused about for example what layer and mode ( user, kernel) the System Wrapper belongs to as well as to what layer and mode the Reference Monitor belongs.

    Also do they both intercept system calls? 

    I do not mean you to write an essay. With as few words as possible.

    Please tell me anything you know about those two interposition techniques.

    Compare contrast them.

    Thank you very much.
