National infrastructure needs a new approach to cyber resilience

The prospect of bringing more of Britain's critical national infrastructure into public ownership has prompted plenty of debate about investment, governance and accountability.

Far less attention has been paid to what it could mean for cybersecurity .

Regardless of where you stand politically, one thing is clear.

Public ownership does not make cyber risk disappear.

If anything, it raises expectations that essential services will be more resilient, more coordinated and better prepared to withstand disruption.

That expectation reflects the reality of the threat landscape.

Energy providers, water companies, transport operators and healthcare organizations all sit at the center of complex digital ecosystems.

Their ability to deliver essential services depends on thousands of suppliers, technology vendors and third parties.

When one organization is compromised, the effects can spread well beyond its own network.

Resilience therefore depends on far more than protecting individual organizations.

It depends on understanding and managing the relationships between them.

If the government is serious about strengthening national infrastructure, cybersecurity must become part of that conversation from day one.

That means moving beyond isolated security programs and towards a model where organizations share intelligence, understand common risks and coordinate their response before disruption spreads.

Critical infrastructure extends beyond organizational boundaries Some of the defining cyber attacks of recent years have demonstrated that attackers are rarely interested in a single target.
