Understanding SharePoint Link Sharing

In a SharePoint environment, sharing links to documents and folders is a common practice. However, when users share links without properly configuring the permissions, it can lead to security and access control issues. In this article, we will explore how to identify who created a link to a SharePoint document and provide best practices for proper link sharing.

The Problem of Insecure Link Sharing

When users share links to SharePoint documents and folders, they can choose from various permission levels, including:

Edit: Allows the recipient to edit the document or folder.
View only: Restricts the recipient to viewing the document or folder only.
Users with existing access: Grants access to the recipient based on their existing permissions.

However, many users tend to leave the default permission level as Edit, which can lead to unintended consequences. This is because the person who receives the link may not have the necessary permissions to edit the document or folder, potentially causing security issues.

Identifying the Creator of a Link

To identify who created a link to a SharePoint document, you can follow these steps:

Method 1: Using the SharePoint Audit Log

Navigate to the SharePoint site: Go to the SharePoint site where the document or folder is located.
Access the audit log: Click on the Settings icon (represented by a gear) and select Site contents. Then, click on the Audit log link.
Filter the audit log: In the audit log, filter the events by Type to Share and User to the person who created the link.
View the share details: Once you've filtered the audit log, you can view the share details, including the person who created the link and the permission level they chose.

Method 2: Using the SharePoint Document Library

Navigate to the document library: Go to the document library where the document or folder is located.
View the document properties: Click on the File tab and select Properties.
View the share details: In the document properties, you can view the share details, including the person who created the link and the permission level they chose.

Best Practices for Proper Link Sharing

To avoid security issues and ensure that links are shared properly, follow these best practices:

1. Use the correct permission level

When sharing links, choose the correct permission level based on the recipient's needs. If the recipient only needs to view the document or folder, use the View only permission level. If the recipient needs to edit the document or folder, use the Edit permission level.

2. Use the 'Users with existing access' permission level

When sharing links, use the Users with existing access permission level to grant access to the recipient based on their existing permissions.

3. Monitor link sharing

Regularly monitor link sharing to ensure that links are being shared properly. Use the audit log to track link sharing activity and identify any potential security issues.

4. Educate users

Educate users on the importance of proper link sharing and the potential security risks associated with insecure link sharing. Provide training and resources to help users understand how to share links correctly.

Conclusion

In conclusion, identifying who created a link to a SharePoint document is crucial for maintaining security and access control in a SharePoint environment. By following the methods outlined in this article and implementing best practices for proper link sharing, you can ensure that links are shared securely and efficiently.
