Checking the integrity: Perform the checking before the program pointer becomes invalid. Randomizing the address space: Arrange the address space positions in the key data area randomly. Typically, buffer overflow attacks require the locations of executable code, which is almost impossible after the ...

The CPU "ignores" the register content when using a memory operand such as [rcx+rsi*imm], in this example if RCX is a valid pointer and RSI is 0(implying access of the first element in an array) an access violation with address 0 occurs instead of reading [RCX]'s content.When...
