Local Security Authority Protection, also known as LSASS Protection or LSA Protection, is a security feature in Windows operating systems designed to prevent unauthorized access and safeguard critical system components. Enabling LSASS Protection helps protect against various types of cyber threats, including credential theft and malware attacks. If you’re looking to turn on LSASS Protection on your Windows system, here’s a comprehensive guide to help you through the process.
What is Local Security Authority Protection?
The Local Security Authority (LSA) is a crucial component of the Windows security infrastructure responsible for managing security policies, authentication, and user credentials. LSASS (Local Security Authority Subsystem Service) is the process that handles these tasks. LSASS Protection enhances system security by isolating and protecting LSASS memory from unauthorized access or exploitation.

Follow these step-by-step instructions to enable LSASS Protection on your Windows system:
Step 1: Open Local Group Policy Editor
1. Press Win + R: Simultaneously press the Windows key and the “R” key on your keyboard to open the Run dialog box.
2. Type “gpedit.msc“: In the Run dialog box, type “gpedit.msc” (without quotes) and press Enter. This will launch the Local Group Policy Editor.
Step 2: Navigate to Security Settings
1. Navigate to Security Settings: In the Local Group Policy Editor window, expand the following folders in the left pane:
– Computer Configuratio
– Windows Settings
– Security Settings
– Local Policies
2. Access Security Options: Under Local Policies, select “Security Options” to display a list of security-related settings in the right pane.
Step 3: Locate LSASS Protection Policy
1. Find LSASS Protection Policy: Scroll down through the list of security options in the right pane until you locate the policy named:
– “System settings: Use Certificate Rules on Windows Executables for Software Restriction Policies”
2. Double-click the Policy: Double-click on the policy to modify its settings.
Step 4: Enable LSASS Protection
1. Configure Policy Settings: In the policy properties window, select the “Enabled” option to enable LSASS Protection.
2. Apply Changes: Click “Apply” and then “OK” to save the changes.
Step 5: Restart Your Computer
After enabling LSASS Protection, it’s recommended to restart your computer to apply the changes effectively.
Additional Considerations:
– Compatibility: Ensure that enabling LSASS Protection does not interfere with any essential applications or services running on your system.
– Group Policy Editor: The Local Group Policy Editor is available in Windows Pro, Enterprise, and Education editions. If you’re using Windows Home edition, you may not have access to this tool.
– System Performance: Enabling additional security features like LSASS Protection may have a minimal impact on system performance, especially on older or resource-limited systems.
Benefits of LSASS Protection:
Enabling LSASS Protection offers several key benefits for system security:
– Mitigates Credential Theft: Protects sensitive user credentials stored in LSASS memory from being accessed or stolen by malicious software.
– Enhances Malware Resistance: Helps defend against malware attacks that exploit vulnerabilities in LSASS processes to gain elevated privileges.
– Strengthens Overall System Security: Contributes to a more robust security posture by implementing proactive measures against unauthorized access and exploitation.
Enabling Local Security Authority Protection (LSASS Protection) is a proactive step towards enhancing the security of your Windows system, particularly in defending against credential theft and malware attacks. By following the outlined steps using the Local Group Policy Editor, you can activate LSASS Protection and strengthen the overall security posture of your system.
Always prioritize regular software updates, antivirus protection, and best security practices to complement LSASS Protection and safeguard your system against evolving cyber threats. If you encounter any issues or have concerns about enabling LSASS Protection, consult with IT professionals or refer to official Windows documentation for further guidance.
