Safeguarding the Global Positioning System:
Mitigating Risks and Threats to GPS Reliability
Exposing the vulnerable attack surface of GPS systems
The reliance on GPS (Global Position Satellite) in mission-critical operations underscores the importance of understanding and mitigating the associated risks and threats. Critical Infrastructure such as Airports and Seaports must take a proactive approach to safeguard critical functions to ensure the safety and efficiency of their operations.
Understanding the risks and threats associated with GPS within mission-critical infrastructure services is crucial. Both Airports and Seaports rely heavily on GPS technology for various essential functions and any disruption or compromise of GPS signals can have serious consequences.

Safeguarding Critical Infrastructure:

Essential Measures to Mitigate Risks and Threats

Implement redundant navigation and communication systems to ensure continued operations even during GPS disruptions.

Develop and test emergency response plans that account for potential GPS disruptions.

Employ security measures to protect against jamming, spoofing, and cyber threats. Regularly update and patch GPS equipment and systems.

Use monitoring and detection systems to promptly identify any interference or anomalies in GPS signals.

Train personnel to recognize and respond to GPS-related issues effectively.

Ensure compliance with aviation and cybersecurity regulations related to GPS use.

Understanding the GPS Attack Surface



This involves the use of devices that emit signals at the same frequencies used by GPS satellites, effectively drowning out the real signals. This can disrupt all systems relying on GPS for navigation and timing.



More sophisticated than jamming, spoofing involves generating fake GPS signals that are mistaken for genuine signals. This can mislead GPS receivers about their actual location or time.


Signal Blocking

Physical obstacles like tall buildings or natural terrain features can block or reflect GPS signals, causing inaccuracies or loss of service.

Cyber Attacks

Since GPS systems are integrated with networked technologies, they are vulnerable to cyber threats that can affect data integrity and availability.
