Ensure VPC Endpoint policy doesn't allow all actions

Security & Compliance

By default, Amazon VPC endpoints are private and accessible only from within the same VPC. However, a VPC endpoint can have an attached policy that defines who can access the endpoint and what actions they can perform. If the policy attached to a VPC endpoint allows all actions, it could potentially grant broad permissions to an attacker, allowing them to escalate privileges or exfiltrate data. This could result in a security breach and compromise of sensitive data. Therefore, it is important to ensure that the VPC endpoint policy does not allow all actions and is configured to only permit the necessary actions required for the endpoint to function.


To ensure that VPC Endpoint policy doesn't allow all actions, you can follow the below remediation steps:

  1. Identify the VPC Endpoint whose policy needs to be updated.
  2. Review the current policy to identify the allowed actions and the source of the policy.
  3. Create a new policy document with the necessary restrictions.
  4. Update the endpoint policy with the new policy document.
  5. Test the updated policy to ensure that it is working as expected.
  6. Monitor the endpoint for any unauthorized access attempts and adjust the policy as needed.
