The advances in connectivity technologies like 5G, fibre optics, wi-fi, and Bluetooth has fuelled our increasing dependence on converged networks. This is an area with enormous commercial potential for BT: we expect the global 5G market to reach over £24 billion by 2026. But that’s small fry compared to the IoT market, which we’re predicting will land somewhere north of £530 billion in 2023.
Our Converged Network Security team is developing the use of automation in network protection, with the help of research covering low-power crypto, next generation security-as-a-service capabilities for NfV (network function virtualisation) and SDN (software defined networks) environments, end-to-end security of 5G networks, security of critical national infrastructure, data protection, and post-quantum crypto.
We’re also looking beyond digital wizardry for inspiration, to biology.
The human immune system shares some core characteristics with cyber defence systems. Like a cyber security service, it operates at different levels throughout the protection cycle:
- In-depth defence: from the skin and mucus, through to B-cells and T-cells, the immune system makes sure the human body is as ready as it can be to repel any invading cells before they can cause any trouble.
- Continuous monitoring: the body is continually assessing self vs non-self, always on the lookout for invasive cells.
- Action during attack: when invasive cells do make it past the first line of defence, the body automatically and rapidly increases the number of immune cells to help defeat the infection.
