I've thought that guard pages referred to the practice of having a page or a couple allocated before and after an accessible region and set to PROT_NONE (any access causes a trap) to prevent any new allocation from making those pages accessible. This way reads/writes at most a page past the beginning/end of our allocation will always fault. I don't see how is this "SSP with a different name" (the goals are similar but the method is very different). Did you mean some other kind of guard pages or am I missing something?
