Today’s cybersecurity environment brings attacks to the utility sector with increased frequency and sophistication – and many are struggling to adapt to the new normal. We can no longer treat cybersecurity as though attacks are rare, one-off events. Instead, utilities need to plan for resilience against the backdrop of constant siege. The best way to approach this new threat environment is to develop an incident response (IR) plan to better detect, contain and eliminate cyberattacks with minimal impact on operations.
In the same way the physical safety of a plant depends on many people understanding their roles and responsibilities to ensure the availability and safety of operations, cybersecurity is a collective undertaking. Teams that have built and practiced an IR playbook in advance of a breach will perform better than teams forced to improvise every time.
