Hawaiian Utility Assesses Cybersecurity and Implements Multiphase Roadmap

Challenge

Power systems are facing new cybersecurity challenges due, in part, to the increased connectivity of OT networks and the growing sophistication of adversaries. Utilities must have a plan that outlines how to prepare for, detect, and prevent attacks as well as how to respond to an event that compromises security. 

Solution

A regulated Hawaiian utility brought in SEL Cyber Services to perform an initial assessment of immediate opportunities for improving cybersecurity. Together, they also developed a multiphase roadmap for maturing the utility’s cybersecurity through formalized policies, procedures, and best practices. SEL Cyber Services continues to work with the utility’s leadership to define requirements and establish priorities for maturing their cybersecurity program and posture. 

Results

In collaboration with SEL Cyber Services, the utility prioritized short-term cybersecurity investments and now has a foundation for evaluating their cybersecurity maturity over time. They adopted several key cybersecurity plans, including an Incident Response Plan, a Disaster Recovery Plan, and a Continuity of Operations Plan. The utility has also practiced tabletop exercises for each of these plans. Additionally, they have improved their OT system’s cyber defenses and increased cross-functional team communication.
