Bridging the IT/OT divide in Utilities: A Friendly Guide

Hey there, CISOs!

Dive into your most comfortable chair, grab your favorite beverage, and let’s chat about something close to our cyber-hearts: the convergence of IT and OT in the utilities sector. It’s a journey—sometimes bumpy, always enlightening—that’s reshaping how we secure our critical infrastructure. And, as we navigate these challenges, let’s make it a bit more personal and a lot less formal.

Ready? Let’s break it down, step by step, and sprinkle in some practical advice along the way… I hope you like analogies.

1. The Great IT-OT Divide: Where We’re Starting From

The Isolation Issue

Imagine IT and OT as two siblings who’ve grown up in the same house but somehow never really spoke. They’ve got so much to offer each other, but the walls between them have kept them apart, making our utility operations vulnerable and, frankly, a bit inefficient.

Making the Connection+

• Risk Assessments: It’s like checking the weather before a big family trip however two siblings are driving to the vacation rental from two different event locations. We will need to plan how each sibling gets to the same location (IT and OT systems) to understand the cloudy areas, potential storms and design a plan to ideally travel through sunny weather. This means identifying which systems are most vulnerable and why, then making a prioritized list to tackle them in a strategic approach.

• Cross-Training Teams: Ever tried learning a bit about your sibling’s favorite hobby? Perhaps you love basketball, and they love golf, and so you play together to share in the other’s experience. That’s cross-training. Get your IT folks to understand the nuances of OT and vice versa. It fosters empathy and collaboration, making your security posture that much stronger. And as siblings are typically a few years apart, it is likely your IT and OT teams and environments are at different levels of program maturity and automation. Each team will need to contribute to each other’s understanding of their respective experience.

2. Embracing Modernization: The Cool Tech Upgrade

Why Stick with the Old?

Holding onto legacy OT systems is like still using a flip phone—it gets the job done, but you are missing out on so much more. Modernizing these systems opens a world of insight, visibility, security, efficiency, and yes, even cost savings.

Getting with the Times

• Unidirectional Connectivity: Think of it as a one-way street where OT data flows to IT without threats hitching a ride back. It’s like sending your data on a safe, one-way trip to where it can be best used. This can be architected and deployed in either a Fed Ramp High SaaS environment and/or a on prem hosting option with both recommended to have advanced encryption capabilities.

• Leveraging ServiceNow OTM: Imagine having a Swiss Army knife for your OT modernization efforts. ServiceNow’s OTM suite is just that, offering tools for asset visibility, inventory, vulnerability management, regulatory complaince management and much more. It’s about bringing the right tools for the job, ensuring you are always ready, no matter what the world throws your way.

3. Enhancing Utility Cybersecurity: Attack Simulation, Proactive Threat Hunting, and Playbook Automation

As we delve deeper into the world of utility cybersecurity, let’s explore three critical strategies that can significantly elevate our defense mechanisms: Attack Simulation, Proactive Threat Hunting, and Playbook Automation. These approaches not only bolster our security posture but also ensure that our utilities are prepared, resilient, and one step ahead of cyber threats.

Attack Simulation: Testing Defenses in a Controlled Environment

The Ultimate Cyber Drill

Attack simulation, or red teaming, is like conducting a full-scale cyber drill without the actual risk. It involves simulating cyberattacks on your systems to test the resilience of your defenses and identify vulnerabilities.

Benefits of Attack Simulation

• Real-World Testing: Simulate a wide range of attacks to see how your systems would stand up to real threats. It’s like a fire drill for your cyber defenses.

• Identify Weaknesses: Uncover vulnerabilities in your systems, processes, and human responses that might not be apparent until they are exploited by an actual attack.

• Enhance Response Readiness: Improve your incident response strategies by identifying gaps in your current protocols and refining your response to various attack scenarios.

4. Proactive Threat Hunting: The Cybersecurity Safari

Tracking Down Hidden Threats

Proactive Threat Hunting is about taking the initiative to search for hidden malware or attackers within your network that have evaded traditional detection methods. It’s the cybersecurity equivalent of going on a safari, where you are actively looking for signs of the adversary in the vast landscape of your network.

Advantages of Proactive Threat Hunting

• Early Detection: Catch threats before they manifest into full-blown attacks, reducing potential damage.

• Insight into Adversary Tactics: MITRE ATT&CK + Threat intelligence = Gain a deeper understanding of how attackers operate, which helps in developing more effective defenses.

• Continuous Improvement: Each hunting expedition provides new insights, which can be used to continually refine and improve security measures. This is a combination of your team experience, benchmarking with industry peers, leveraging technology platform capabilities and an experience consulting partner to help you instantiate best practices.

5. Playbook Automation: The Cybersecurity Conductor for your orchestra

Orchestrating Security Responses

Playbook Automation involves the use of predefined action sets to respond to various cyber threats automatically. Think of it as having a conductor for your cybersecurity orchestra, ensuring every section plays its part at the right time. But like any professional orchestra, practice makes perfect, so having scheduled and planned tabletop exercises can significantly improve operational effectiveness.

Streamlining Incident Response

• Speed and Efficiency: Automate responses to common threats, significantly reducing the time to respond and mitigate potential damage.

• Consistency: Ensure that every incident is handled consistently, following best practices and reducing the likelihood of human error.

• Scalability: Manage a large volume of alerts effectively, allowing your security team to focus on more complex tasks.

• Context: Having a unified data model between IT and OT teams with segmented data sets can provide powerful insights and metrics to executive leadership.

Elevating Utility Cybersecurity to New Heights

Integrating Attack Simulation, Proactive Threat Hunting, and Playbook Automation into your cybersecurity strategy propels your utility’s defenses from reactive to proactive. These approaches not only enhance your ability to withstand and respond to cyber threats but also build a culture of continuous improvement and resilience. Technology can play an additional level of maturity when implementing and analyzing digital twins to maximize asset effectiveness, efficiencies, and overall lifespan on an asset.

In the evolving landscape of utility cybersecurity, staying ahead means being prepared for anything. By adopting these strategies, we’re not just defending against cyberattacks; we’re actively working to anticipate, understand, and neutralize them before they can impact our critical infrastructure. Let’s embrace these practices to ensure our utilities are not only secure but also resilient and ready to face the cyber challenges of tomorrow. Proactive planning can secure a thriving future for our utilities, powered by foresight, innovation, and unwavering vigilance.

6. The ServiceNow OTM Magic Wand

Integrating Everything Under One Roof – The magic of a unified data model with the benefits of data segmentation.

Combining IT and OT under a single management umbrella feels like moving from a cluttered desk to an organized workspace. Everything you need is right there, streamlined, and efficient. Let’s image you are the organized sibling with a clean an organized room (policies and controls in SharePoint or a secure and single repository), and your sibling’s room is pig stye ( policies, controls, SOPs are on this laptop, that tablet, this SharePoint file, that google drive, and some of it is in your teams brans as they have been there for 20+ years and they just know how it’s done). I’m confident everyone reading this was the orderly sibling.

Practical Magic Tips

• OT Asset Visibility and CMDB: Use this to keep track of all your OT assets, like a detailed inventory list. This isn’t just about knowing what you have; it’s about understanding the state of each asset, its software version, and its health.

• Vulnerability and Incident Response: This is your rapid response team. When vulnerabilities are spotted, you need to move quickly and effectively, patching holes and securing your network.

• Compliance Management: Think of this as your rulebook and your gatekeeper. Keeping up with NERC-CIP and TSA compliance is non-negotiable, and controlling who has access to what ensures that only the right hands are on your critical systems.

• Identity and access Management: Ensuring your NERC and TSA data is encrypted and not accessible by your IT platform admins is critical for security and compliance. Segmenting data is step one, encryption of the data is step two, and access controls are step 3 for NERC CIP and TSA guidelines.

7. Keeping Data Safe and Sound
