What is Cyber Resilience for Connected Infrastructure?
The growth of smart cities and utilities brings immense benefits - from intelligent traffic control to optimized energy distribution. But increased connectivity also creates vulnerabilities. As we connect critical infrastructure to the internet through sensors, meters, and control systems, resilience becomes crucial.
These internet-of-things (IoT) devices are attractive targets for cyberattacks. Their connectivity allows remote access from anywhere. And many connected devices lack strong security controls of typical IT networks. Attackers can leverage IoT to infiltrate larger systems upstream.
So as cities and utilities embrace the future, they must prioritize resilience. Smart infrastructure must adapt to emerging threats and withstand incidents. When (not if) vulnerabilities are exploited, resilient systems contain the impact and rapidly restore functions.
Strategies for Resilience
There are several best practices for enhancing resilience:
Strict access controls on all endpoints and data
Network segmentation to limit lateral movement
Rapid isolation and shutdown procedures for compromised devices
Backups and redundant systems to minimize disruptions
Continuous monitoring to enable adaptive responses over time
Well-designed IoT networks implement these measures at scale for full coverage. cyber resilience must be baked into smart city projects from the start.
Bolting on security as an afterthought leaves gaps. With sound architecture, smart infrastructure withstands incidents, contains damages, and maintains continuity of operations.
Connected devices deliver transformative capabilities. But the cyber risks cannot be ignored. Prioritizing resilience helps smart cities and utilities benefit from innovation while keeping infrastructure secure and reliable. As connectivity and complexity grow, so must our vigilance. Cyber resilience will only gain importance for the safety and functioning of our digital cities and increasing infrastructure.
