Employ trend analyses to determine if control implementations, the frequency of continuous monitoring activities, and the types of activities used in the continuous monitoring process need to be modified based on empirical data.
Performing trend analyses on a spacecraft’s monitoring data often yields early warnings of impending issues, ranging from slow shifts in a payload’s power usage to unusual spikes in network message counts. By comparing these metrics over days or weeks, analysts can separate benign mission evolutions (e.g., scheduled sensor calibrations) from potentially malicious shifts (e.g., repeated login attempts during periods of inactivity). Clear visual dashboards or anomaly flags can highlight patterns not obvious in short-term snapshots. The resulting insights help mission stakeholders preempt major incidents with strategic adjustments, like quarantining a suspect subsystem or uploading software patches before anomalies degrade the spacecraft’s mission performance.
Maintaining ongoing awareness of information security, vulnerabilities, and threats to support organizational risk management decisions.
