Plan IoT security the right way: SIM ID, private APN and traffic analysis

How do companies secure connected devices in a cost effective and scalable way? This episode is for IT and OT leaders who deploy many devices in the field and move PoCs into operations. The central question is how to balance risk, cost, and device constraints such as battery operation and limited compute. Peter shows how to use existing network functions deliberately. SIM based authentication provides a unique device identity; private APN, IP filtering, static IP addresses, MPLS or IPsec protect communication into your own network; network side anomaly detection flags irregularities and prevents misuse of removed SIM cards. In critical applications such as smart metering you add certificate management, end to end encryption, secured firmware updates, and tamper detection on the device. Looking ahead, 5G opens options such as network slicing for separate security domains and the SIM as a secure element. The design also prepares you for NIS2 requirements. The result is a security concept that fits the use case, protects devices and budgets, and scales. Note: Meet A1 Digital in person.
