WebSep 19, 2024 · Data Execution Prevention (DEP) marks certain regions of memory as non-executable. This helps protect against buffer overflows since, even if the attacker can modify a return address to point to their shellcode, it won’t be executed by the program. WebA buffer is a sequential memory allocation or region that might hold anything from integer arrays to character strings.
