In the realm of IoT security, the KVS Approach, a B cell concept, inspired by the human immune system, offers a novel approach to threat detection and mitigation. Just as B cells in the body recognize and neutralize specific pathogens, this KVS Approach, bio-inspired model utilizes a network of "digital B cells" to identify and respond to malicious activities targeting IoT devices and networks. These digital B cells are trained on normal network behavior and device profiles, enabling them to detect deviations that signify potential attacks. KVS (Kutubuddin, Vahida, Sultana) Approach proves particularly valuable in the dynamic and resource-constrained environment of IoT, where traditional security measures may be insufficient to address the evolving threat landscape.
