What are the two primary means of Electronic Protection?

The two primary means of Electronic Protection are best characterized as passive and active measures. Passive measures typically involve strategies designed to enhance the survivability of electronic systems without active intervention. This includes techniques such as physical hardening, signal masking, and frequency hopping, which help to minimize the vulnerability of systems to electronic attacks.

Active measures, on the other hand, involve direct actions taken to mitigate or counteract electronic threats. This can include jamming enemy signals, employing deception techniques, and utilizing various countermeasure systems designed to disrupt or negate the effectiveness of incoming threats.

These dual approaches work together to create a comprehensive Electronic Protection strategy, ensuring effective resilience against various electronic warfare tactics. Other options, while relevant in broader contexts of military tactics and operations, do not align as closely with the defined aspects of Electronic Protection. For instance, offensive and defensive strategies may incorporate electronic warfare but do not focus solely on the protection aspect, while surveillance and communication jamming pertain to specific actions rather than overarching protection means.
