Anomalous Frequency of Sensor Data Updates

Monitors for deviations in sensor update rates, which could affect spacecraft control loops. Detects unexpected changes in the frequency of sensor data updates, which could suggest spoofing or tampering attempts.

ID Name Description
EX-0014.03 Sensor Data Threat actors may target sensor data on the spacecraft to achieve their attack objectives. Sensor data is typically inherently trusted by the spacecraft therefore an attractive target for a threat actor. Spoofing the sensor data could affect the calculations and disrupt portions of a control loop as well as create uncertainty within the mission thereby creating temporary denial of service conditions for the mission. Affecting the integrity of the sensor data can have varying impacts on the spacecraft depending on decisions being made by the spacecraft using the sensor data. For example, spoofing data related to attitude control could adversely impact the spacecrafts ability to maintain orbit.
