Countermeasures - VPNs

Virtual Private Networks (VPN) allow the secure transfer of data over public networks through private connections from the private host network to the remote sites. Information over VPNs is kept secure through data encryption. VPNs also require some level of authentication from the user before he or she can access the network, so this adds another level of security. Another advantage to using VPNs is the fact that they're relatively cheap to set up and they can be accessed wherever there is internet access.
