DEP: Data Execution Prevention in Cybersecurity
DEP stands for Data Execution Prevention. Data Execution Prevention is a security feature that marks memory regions as non-executable, preventing code from running in areas meant only for data. DEP stops classic buffer overflow exploits that inject shellcode into the stack or heap.
How DEP Is Used in Cybersecurity
Penetration testers verify DEP status on target systems and use techniques like ROP to bypass it during binary exploitation. Security engineers confirm DEP is enabled across endpoints and servers as part of system hardening. Security architects require DEP support in procurement standards for all operating systems and firmware.
