Enable/Disable ASLR in Windows Defender

What is the ASLR? #

Address Space Layout Randomization (ASLR) is a security feature in Windows that helps protect against buffer overflow attacks. It randomizes the memory addresses used by system and application processes, making it difficult for attackers to predict the location of specific functions or data in memory. By doing so, it reduces the likelihood of successful exploits that rely on knowing these memory locations. ASLR is part of the overall strategy to increase the complexity and difficulty of launching attacks on a system.

For more detailed information, you can refer to the Microsoft documentation on ASLR.

Enable/Disable ASLR in Windows Defender #

1. 1. Open Windows Security: Press the Windows key, type “Windows Security,” and press Enter to open the Windows Security app.
   2. Go to App & Browser Control Settings: In the Windows Security app, click on “App & browser control” in the sidebar menu.

   6. Edit ASLR Setting: Once Microsoft Defender Antivirus is added to the list, locate the “Address Space Randomization” setting. By default, it should be set to “On by default.” If it’s not, click on the dropdown menu and select “On by default.”
   7. Apply Changes: After setting ASLR to “On by default,” click “Apply” to save the changes.
   8. Restart if Required: Depending on your system settings, you may need to restart your computer for the changes to take effect.

Enabling ASLR in Windows Defender helps enhance the security of your system by randomizing the memory locations of system processes and making it more difficult for attackers to exploit vulnerabilities.
