Executable Space Protection is a security feature used in computer systems to prevent the execution of code in certain areas of memory that should only contain data. This helps to mitigate risks from attacks like buffer overflows, where malicious code could be injected and executed from these data areas. By marking memory regions as non-executable, the system can stop unauthorized code from running. This protection is commonly implemented in modern operating systems, such as Windows and Linux, to enhance overall system security. It works alongside other security measures, like Address Space Layout Randomization (ASLR), to create a more robust defense against various types of cyber threats.
