Abstract

Fully securing networks from remote attacks is recognized by the IT industry as a critical and imposing challenge. Even highly secure systems remain vulnerable to attacks and advanced persistent threats. Air-gapped networks may be secure from remote attack. One-way flows are a novel approach to improving the security of telemetry for critical infrastructure, retaining some of the benefits of interconnectivity whilst maintaining a level of network security analogous to that of unconnected devices. Simple and inexpensive techniques can be used to provide this unidirectional security, removing the risk of remote attack from a range of potential targets and subnets. The application of one-way networks is demonstrated using IEEE compliant PMU data streams as a case study. Scalability is demonstrated using SDN techniques. Finally, these techniques are combined, demonstrating a node which can be secured from remote attack, within defined limitations.
