Effective airspace protection is achieved through sequential layers of defense, each increasing the difficulty of interference along defined approach paths and low-altitude volumes leading to aircraft, runways, and critical infrastructure.

To build operational resilience, each ordered layer must increase both the quality and coverage of detection, tracking, and identification capabilities as threats move closer to consequence.

This cumulative approach ensures that no single sensor failure results in loss of situational awareness and guards against known failure modes in complex airport environments.

This is the foundation of Cumulative Defense Strategy.

Security architecture is modified where performance fails to improve across ordered defense layers protecting approach paths, airspace volumes, and near-asset environments.

Measurement identifies precisely where layers are insufficient, misaligned, or redundant, allowing investment to be applied only where it produces measurable risk reduction.

This approach replaces technology-driven deployments with outcome-driven design, while maintaining cost optimization across complex airport operating environments.

Cost-to-benefit calculations are part of the measurable outcome.
