BT Research is working on a cybersecurity project called the “network immune system” (NIS), inspired by the human biological system. The autonomous cyber defense system is a pilot project for now, but the goal is to build network‑driven cybersecurity services tailored to enterprise customers as an as-a-service product, according to BT’s Network Platform and Security Research Director, Nektaria Efthymiou. NIS is designed to be integrated with BT’s network management tools and use a digital twin of the network to profile how threats might spread through the network. It uses a ‘sense–reason–act’ cycle to protect networks, Efthymiou described. Sense: it first detects threats using machine learning on network telemetry, authentication patterns and external threat intelligence, identifying anomalies and zero-day Reason: next, it analyses…
