Memory Protection

Definitions

1. Hardware and software mechanisms that restrict how memory can be accessed or executed, such as page permissions, isolation, ASLR, DEP, and control-flow mitigations. Memory protection reduces the reliability and impact of many classic exploitation techniques.

   In plain English: System defenses that stop programs from misusing memory in dangerous ways.

   Example: "The exploit only worked on the older build because newer memory protection features blocked the executable payload pages."
