Secure communications?

We keep it that way.

Cloud, big data and the internet of things (IoT) are much-debated key IP based technologies that are being used in ever expanding areas of application in both the private and public sectors. IP based technology is even gaining ground in critical infrastructures such as the energy supply (smart grid/smart meter). Previously physically separated control networks are now converging with the classic, public IT infrastructure.
Modern IP technology is also finding its way into the field of air traffic control (ATC). High-performance backbone networks and classic protocols such as internet telephony (VoIP) enable efficient and secure air traffic control – beyond existing geographical and technical boundaries.

Secure networks for air traffic control

This development, however, also brings with it new dangers from cyberattacks and malware in networks. Strict, physical separation of ATC communications networks and the public network infrastructure offers a high level of security, but this is very difficult and cost-intensive to implement over large distances. In addition, this means you have separate cables running through public property that can be easily tapped and manipulated using simple technical means.

Rohde & Schwarz Cybersecurity offers cutting-edge solutions that fully meet these challenges. High-security encryption technology protects data transmission in networks against undesired recording, manipulation and sabotage.

Powerful, next generation firewalls proactively protect IT networks against complex cyberattacks, malware infection and zero day exploits. Using a whitelist approach, only desired data traffic passes through the networks while all other data is blocked. At the same time, the continuously operating application validation system checks the contents of protocols and applications, efficiently preventing concealed attacks even in approved protocols.
