TECHNOLOGY hardware-based networks. The explosion of IoT devices connected via 5G, many with minimal built-in security, introduces millions of potential new entry points for malicious actors.
Mitigating these risks requires a move away from legacy perimeter-based security to a Zero Trust architecture, where trust is never assumed and verification is required from every user and device.
AI-driven, real-time threat detection and robust, layered defences are critical to securing this new, complex environment.
The energy paradox While 5G is significantly more energyefficient per bit of data transmitted than 4G, the projected 1000-fold increase in data traffic and the proliferation of new edge data centres could lead to a substantial rise in the industry’ s overall energy consumption.
This presents a major challenge to the data centre sector’ s sustainability goals.
The high power density required by edge sites, particularly those supporting AI workloads, will demand innovations in energy-efficient design, such as advanced liquid
