Issue/Introduction

In Google From, the editor has the ability to choose "Anyone with the link" option, this creates a potential data exfiltration risk.

Resolution

1. 1. 1. To block this, you will need to first create a Google Froms custom Gatelet
      2. You can block action by creating an Access Enforcement via Gatelets policy, adding Google Forms to the Cloud Service List:
         
         • 
      3. Set Object to Link and Access Type to Make Public
         • 
      4. Check the Block activity checkbox
         • 
      5. Once you save the policy and test generating the public link, the action will be blocked and you should see the agent pop-up page and the x-Elastica_block in the headers
