Network Vulnerability

The vulnerability of GNSS systems to various signal incidents is well known. The rapid proliferation of GNSS systems has embedded these vulnerabilities into critical national infrastructure as well as corporate infrastructures that rely on GNSS-delivered position, navigation and timing (PNT) for daily operations. The widespread deployment of GNSS makes it impractical to replace all fielded GNSS systems in a timely or cost-effective manner.

Savitri Telecom provides a portfolio of technologies, products, and services that enables operators of Critical Infrastructure to construct a secure and robust PNT network that is resilient to GNSS errors as well as errors coming from other sky-based delivery channels such as Galileo, GLONASS, BeiDou, or another.

GNSS Jamming and Spoofing

Systems which rely on GNSS for reception of Position, Navigation and Time (PNT), have been determined by national security agencies across the globe as potential cybersecurity attack vectors.

GNSS jamming and spoofing solution is a platform that analyzes GNSS signal reception. GNSS signal data is received and evaluated from each satellite to ensure compliance along with analyzing received signal characteristics. Further enhances field proven GNSS protection capabilities with new features such as Trusted Time Anomaly Detection, GPS Subframe Reference Detection.

Time Security

The role of accurate timing in reducing network security risk. In order to enable systems to sync up, the organization must essentially leave a door open to its firewall through which time information can get in. From a security perspective, that is a big problem. Nefarious hackers know all too well that many companies use this technique to maintain network time. They even know exactly what door on the firewall will be open, since NTP is designed to use a specific port on a firewall—Port 123. In effect, then, this approach to keeping network time is like sending an invitation to an attacker, telling him how to attack your network.

Not all time-related security risks relate to NTP and public time servers, however. Poor synchronization in general can lead to unacceptable levels of risk.

Time servers that synchronize to satellites that constantly orbit the earth that are used to support the Global Navigation Satellite System (GNSS) is outfitted with atomic clocks. Time servers synchronize with the clocks on those satellites, which are accurate to approximately one-millionth of a second to UTC. Each networked system can then synchronize with the Time Server device as often as is deemed necessary.

Even an entry-level time server can keep thousands of client systems in sync. For a relatively small investment, companies can be assured that out-of-sync systems won't result in far more costly productivity or data losses and that keeping accurate time won't open up their network to security risk.
