NDVI stands for Normalized Difference Vegetation Index. It is a remote-sensing metric calculated from satellite or drone imagery, typically by comparing red and near-infrared light reflected by plants. Higher NDVI values usually indicate denser, healthier vegetation, while lower values can suggest stress, sparse growth, or bare soil. In precision agriculture, NDVI helps track crop vigor across fields over time and supports decisions about irrigation, fertilization, scouting, and yield planning.
In cyber security, NDVI matters because it is more than a map layer: it is operational intelligence. If attackers steal NDVI datasets or the imagery behind them, they may learn which fields are performing well, when problems appear, and where farm operations are focused. That can aid extortion, competitive intelligence, or phishing that sounds credible to agronomy staff. Defenders should treat NDVI products as sensitive business data, protect them with strong authentication, encryption, and access logging, and secure the APIs and cloud storage that deliver them.
