Scientists have demonstrated a real-time defence framework designed to protect modern mobile networks and future 6G infrastructure from evolving cyber threats. Researchers at the University of Surrey have developed an artificial intelligence-based defence system capable of identifying and neutralising sophisticated cyber-attacks targeting 5G networks in under 100 milliseconds. The team says the approach could strengthen the security of next-generation mobile networks, including the future transition to 6G. As telecommunications infrastructure evolves, modern 5G systems are increasingly built on open, modular architectures. These designs allow operators to upgrade and expand networks more easily, but they also introduce new cybersecurity challenges. More interconnected components and software-driven functions create additional entry points for attackers. To address these vulnerabilities, the Surrey researchers developed a security framework called TwinGuard that combines AI with a digital twin of the network. The digital twin acts as a continuously updated virtual model of the live system, allowing the AI to monitor activity and detect unusual behaviour in near real time. Digital twin approach enables rapid response Unlike traditional security tools that rely heavily …

What AI builders can learn from fraud models that run in 300 milliseconds

Fraud protection is a race against scale.  For instance, Mastercard’s network processes roughly 160 billion transactions a year, and experiences surges of 70,000 transactions a second during peak periods (like the December holiday rush). Finding the fraudulent purchases among those — without chasing false alarms — is an incredible task, which is why fraudsters have been able to game the system.  But now, sophisticated AI models can probe down to individual transactions, pinpointing the ones that seem suspicious — in milliseconds’ time. This is the heart of Mastercard’s flagship fraud platform, Decision Intelligence Pro (DI Pro).  “DI Pro is specifically looking at each transaction and the risk associated with it,” Johan Gerber, Mastercard’s EVP of security solutions, said in a recent VB Beyond the Pilot podcast. “The fundamental problem we’re trying to solve here is assessing in real time.” How DI Pro works Mastercard’s DI Pro was built for latency and speed. From the moment a consumer taps a card or clicks “buy,” that transaction flows through Mastercard’s orchestration layer, back onto the network, and …
