O365 Secure Link Created [splunk-o365]

This use case detects when a secure link is created for files and folders in SharePoint Online or OneDrive for Business. These links allow users to access shared content, making it a potential security risk if not managed carefully. A threat actor could abuse the secure link functionality to gain access to sensitive data, bypass authentication mechanisms, and exfiltrate information.
