This is done by marking data pages as non-executable. Data Execution Prevention is a security technique that is used to prevent the execution of code from such data pages.

After arbitrary code has been inserted, they can carry out attacks such as buffer overflows. Attackers use these sections to initiate code injection attacks. Several of the major security improvements are given below in greater detail.ĭuring the execution of a process, it will contain several memory locations that do not contain executable code. developers enforced a strict code review of all new code and they performed refactoring and code review of older OS code. Windows 7 has tried to address these issues by following a Secure Development Life Cycle (SDLC), i.e. In today’s increasingly connected world we cannot allow our systems to be compromised without dire consequences. They are also a popular target for hackers due to these flaws. Windows-based operating systems have always been plagued with a host of security flaws and vulnerabilities, this is mainly because the systems were not designed with secure computing in mind.
