Stack Buffer Overflow - Protection Schemes

Protection Schemes

Over the years a number of schemes have been developed to inhibit malicious stack buffer overflow exploitation. These may usually be classified into three categories:

  • Detect that a stack buffer overflow has occurred and thus prevent redirection of the instruction pointer to malicious code.
  • Prevent the execution of malicious code from the stack without directly detecting the stack buffer overflow.
  • Randomize the memory space such that finding executable code becomes unreliable.

Famous quotes containing the words protection and/or schemes:

    A strong egoism is a protection against disease, but in the last resort we must begin to love in order that we may not fall ill, and must fall ill if, in consequence of frustration, we cannot love.
    Sigmund Freud (1856–1939)

    Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.
    James Conant (1893–1978)
