A sample answer to question 1

How would you develop a three-year cyber security strategy and roadmap, and make sure it stays aligned with the business?

I'd start with the business strategy: growth plans, new markets, acquisitions, cloud moves, and regulatory exposure, because security strategy should enable those. I'd combine that with a threat picture, our current maturity assessed against a framework like NIST CSF 2.0, and what recent incidents and audits revealed. From that, I'd identify a small number of strategic themes, such as identity-centred security, resilience and recovery, secure delivery, and risk-informed governance, each with clear outcomes. The roadmap would sequence initiatives by risk reduction, dependency and capacity, with year one concentrating on foundational gaps and quick wins. I'd cost it, show funding scenarios, and validate it with the executive team and key business leaders so they see their priorities in it. To stay aligned, I'd review the strategy every six months, track delivery and outcome metrics, and be willing to drop or swap initiatives when the business or threats shift. A strategy that can't flex becomes shelfware.

Common mistake to avoid: Producing a technology wish list; building it in isolation from the business
