Security for IoT works best “by design,” built in across four layers: devices, networks, gateways, and platforms. Devices need strong access control (ACLs), encrypted data in transit, and anomaly monitoring—often via VPNs and network analytics. Networks (cellular, satellite, Wi-Fi, etc.) should follow the CIA triad: confidentiality (permissions, encryption), integrity (validation, audits), and availability (resilient auth and access paths). Gateways at the edge add tamper detection, at-rest encryption, and crypto engines. Platforms deliver connectivity, device management, analytics, and services. An ideal tool offers real-time traffic visibility, complex rules, endpoint control, and clear reporting—e.g., KORE SecurityPro.
