Who is Address Space Layout Randomization?

Address Space Layout Randomization is like giving your toys a secret hide-and-seek every time you play.

Imagine you have a toy box where all your favorite toys live, cars, blocks, and action figures. Usually, they’re always in the same spots: the red car is on top, the blue block is in the middle, and the action figure is at the bottom. But one day, you decide to make it harder for your brother to find his toys. So every time he comes over, you rearrange them, sometimes the red car goes to the bottom, the blue block goes to the top, and the action figure hides in the middle. That way, even if he knows where they usually are, it's much harder to find them quickly.

Address Space Layout Randomization works the same way inside a computer. When programs run, their parts, like memory, code, and data, are placed in random spots instead of fixed ones. This makes it harder for hackers to guess where important things are located and attack them.

Without this trick, hackers could easily find the same spots every time, like finding your brother’s toys always in the same place. But with random hiding spots, they have to work a lot harder, just like your brother has to search the whole toy box each time!
