Ensure that no VMInstace allows incoming traffic from 0.0.0.0/0 to a known UDP port.

To implement the principle of least privilege and reduce the possibility of a breach, Always make sure that VMInstances are being accessed by expected traffic only. Make sure that the network, to which VMInstances belong, Should not have any enabled firewall rules with an 'allow' effect for incoming traffic from 0.0.0.0/0 to the well-known UDP ports.
