Recognize [Assignment: organization-defined classes or types of intrusions] and initiate [Assignment: organization-defined response actions] using [Assignment: organization-defined automated mechanisms].
Although physical intrusion is essentially a ground-segment concern, for unmanned space vehicles, automated intrusion recognition and response are crucial during integration, testing, or storage phases before launch. In satellite assembly cleanrooms or secure high bays, advanced sensors (e.g., lidar, infrared) and intelligent access control systems can monitor unauthorized movements in real-time. Upon detecting suspicious activity—such as forceful door entry or unusual after-hours presence—these systems can automatically initiate countermeasures, from local alarms to lockdown protocols that isolate the spacecraft. A robust architecture might also integrate these systems with a Security Operations Center (SOC), enabling automated notifications to off-site stakeholders. Such rapid, automated interventions are especially valuable given the high stakes of spacecraft hardware, which can be irreplaceable if tampered with. The ultimate goal is to provide an unbroken chain of custody and comprehensive situational awareness for all mission-critical components.
The [spacecraft] shall be able to identify threats within the operational environment and maneuver to avoid physical contact or utilize shielding to mitigate electromagnetic attacks.{PE-6(2)}
