Address Space Layout Randomization (ASLR)

E427682

exploit mitigation memory protection mechanism security technique

Address Space Layout Randomization (ASLR) is a security technique that randomly arranges the memory addresses used by key data areas of a process to make it harder for attackers to predict and exploit them.

How this entity was disambiguated

This entity first appeared as the object of triple T4279160 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
