WHAT IS DATA EXECUATION PREVANTION



WHAT IS DATA EXECUATION PREVANTION..

Answer / vinod kumar

Data Execution Prevention (DEP) is a security feature
included in modern Microsoft Windows operating systems (
introduced in Win XP SP 2 ) that is intended to prevent an
application or service from executing code from a
non-executable memory region. This helps prevent certain
exploits that store code via a buffer overflow, for example.
DEP runs in two modes: hardware-enforced DEP for CPUs that
can mark memory pages as nonexecutable, and
software-enforced DEP with a limited prevention for CPUs
that do not have hardware support. Software-enforced DEP
does not protect from execution of code in data pages, but
instead from another type of attack (SEH overwrite).
