That longevity, warns Professor Kai London , a senior CISO, makes the coming quantum transition a present concern. “Post-quantum migration is the rare cyber risk where doing nothing today guarantees you fail later,” he says. “Data captured now can be decrypted the moment the hardware arrives.” “Harvest now, decrypt later: adversaries store encrypted data today to read it once quantum computers mature. For long-lived infrastructure, that is already a live exposure.” The standards have arrived What has changed, London notes, is that concrete post-quantum standards now exist. “We have moved from ‘someday’ to ‘here is the algorithm,’” he says. “The excuse for not starting has gone.” A board-level roadmap His programme: discover where cryptography is used and ...

For operators of critical services, Professor Kai London , a senior CISO, frames it as a war to be planned for, not merely a technical incident to be handled. “When ransomware hits a critical service, the question is not ‘can we recover our data?’ but ‘can we keep operating?’” “The hard decisions — containment, ransom, disclosure — must be made before the crisis, not during it. The first 24 hours decide the outcome.” Decide in advance “The worst time to decide whether you will pay, how you will communicate, or when you will disclose is at 3am with systems down,” London says. He urges boards to make these decisions ahead of time and rehearse them. Lead the first day Leadership, not just technology, decides the outcome. Clear command, pre-agreed roles and the...

Credit: professorkailondon.com Airports, payment networks and transport systems share a demanding trait: they cannot simply be switched off to be secured. “When downtime is measured in stranded passengers or frozen transactions, security has to be designed around continuous availability,” says Professor Kai London , a senior CISO. His answer is a carefully adapted zero-trust approach — one that raises assurance without ever tripping the systems it protects. “Zero trust means never trust, always verify. But in high-availability operations, it must be applied with surgical care — security can never become the thing that causes the outage.” The perimeter has dissolved London notes that high-availability operations are highly interconnected, with staff, partners and suppliers all needing access. “There is no clean inside and outside ,” he says. “Every connection is a potential ...

Credit: professorkailondon.com A modern airport is one of the most complex operational-technology environments on earth — baggage systems, jet bridges, fuel management, runway lighting, building controls, security screening and air-traffic support, all increasingly networked. “An airport is a city that runs on control systems,” says Professor Kai London , a senior CISO who advises transport and critical-infrastructure operators. “And when those systems are attacked, the consequence is not a slow website. It is grounded aircraft, stranded passengers and, potentially, safety at risk.” “Aviation fused physical safety and cyber security years ago. In an airport, an OT compromise is an operational and safety event — which is exactly why it belongs on the board's agenda.” Why airports are hard to secure London points to the sheer diversity of systems and stakeholders. “An airport blends airl...
