Address Space Layout Randomization - Benefits

Benefits

Address space randomization hinders some types of security attacks by making it more difficult for an attacker to predict target addresses. For example, attackers trying to execute return-to-libc attacks must locate the code to be executed, while other attackers trying to execute shellcode injected on the stack have to find the stack first. In both cases, the related memory addresses are obscured from the attackers. These values have to be guessed, and a mistaken guess is not usually recoverable due to the application crashing.

Famous quotes containing the word benefits:

    It is too late in the century for women who have received the benefits of co-education in schools and colleges, and who bear their full share in the world’s work, not to care who make the laws, who expound and who administer them.
    J. Ellen Foster (1840–1910)

    I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.
    Benjamin Harrison (1833–1901)

    It is with benefits as with injuries in this respect, that we do not so much weigh the accidental good or evil they do us, as that which they were designed to do us.—That is, we consider no part of them so much as their intention.
    Laurence Sterne (1713–1768)
