Serveurs de fichiers - Episode 14 - Enumération basée sur l'accès

Introduction

This tutorial will guide you through enabling Access-Based Enumeration (ABE) on file shares in Windows Server 2022. ABE is a feature that restricts file and folder visibility based on user permissions, enhancing security and user experience. This step-by-step guide will help you understand and activate this functionality effectively.

Step 1: Understand Access-Based Enumeration

• Access-Based Enumeration (ABE) allows users to see only the files and folders they have permission to access.
• This feature is particularly useful in environments where sensitive data is stored, ensuring that users do not see unnecessary or unauthorized content.

Step 2: Prerequisites for ABE

• Ensure you have Windows Server 2022 installed.
• Administrative privileges are required to enable ABE.
• Familiarize yourself with the file share and NTFS permissions setup on your server.

Step 3: Enable ABE on File Shares

1. Open Server Manager

   • Click on the Windows Start menu and select Server Manager.

2. Access File and Storage Services

   • In Server Manager, navigate to File and Storage Services in the left-hand menu.

3. Select Shares

   • Click on Shares to view existing file shares.

4. Choose the Appropriate Share

   • Right-click on the file share where you want to enable ABE and select Properties.

5. Enable ABE

   • In the Properties window, go to the Settings tab.
   • Check the box for Enable access-based enumeration.
   • Click OK to apply the changes.

Step 4: Verify ABE Functionality

• To confirm ABE is working, log in with a user account that has limited permissions.
• Navigate to the file share and observe that only accessible files and folders are displayed.

Common Pitfalls

• Ensure that the user accounts have the correct permissions set up in both NTFS and share permissions.
• If ABE does not appear to be working, double-check that the feature is enabled for the specific share and that the user is logged in with the correct account.

Conclusion

Enabling Access-Based Enumeration in Windows Server 2022 enhances security by restricting file visibility based on user permissions. By following the steps outlined above, you can easily configure ABE on your file shares.
