Monitoring

Monitoring of the system's state to early detect undesirable behaviors or interactions. In case of Denial-of-Service attacks, the Ground Station should be able to notice the status of the receiver. If the receiver is targeted by attacks, the power of the transmitter should be increased, rising the receiver's threshold level, and cutting out the malicious signals.
Monitoring of the radio channel permits the identification of messages sent by unauthorized users towards the spacecraft. Monitoring of the internal system may discover malignant or erroneous operations. ^[1]
