Bracing for the Cyber Storm: What CISOs Can Learn from Recent Natural Disasters

As a CISO, you’re no stranger to weathering the storm. Whether it’s fending off the latest cyber threat or navigating the turbulent waters of regulatory compliance, your ability to assess and respond to risk is critical to the success of your organization. But when it comes to the thorny issue of “materiality,” many CISOs find themselves caught in the cyber equivalent of a sudden April shower - unprepared and unsure of how to chart a course that aligns with the expectations of regulators and investors.

On the Friday morning of April 5th, a 4.8-magnitude earthquake struck near New York City, shaking buildings up and down the East Coast and surprising residents in an area that rarely experiences notable seismic activity. And in the United Arab Emirates, heavy rains on April 16th caused devastating floods, affecting cities like Dubai, Sharjah, and Ras Al Khaimah. According to the Emirati National Center for Meteorology, this was the country’s heaviest rainfall recorded in 75 years. These natural disasters served as stark reminders that even the most seemingly stable environments can be upended by unexpected events. The same holds true for the world of cybersecurity.

Think of a material cyber incident like a hurricane or tornado ripping through your organization. When a major storm strikes, it can wreak havoc on a company’s operations, supply chains, and financial performance. Investors immediately sit up and take notice, scrutinizing the impact on the business from every angle. The SEC’s new cyber disclosure rules demand that CISOs be able to quickly determine whether a cyber event is “material” - that is, whether it has a substantial likelihood of being considered important by a reasonable investor.

This is no easy feat, as materiality is not a one-size-fits-all metric. It requires a nuanced, multifaceted analysis that goes beyond simply crunching the numbers. Just as you would assess the impact of a natural disaster, CISOs need to consider the full spectrum of consequences, both tangible and intangible, that could sway an investor’s decision-making process.

Think about it this way - a data breach that costs your company $1 million to remediate may not be considered material if it represents a small fraction of your annual revenue. But what if that breach resulted in widespread operational disruptions, damaged your brand reputation, and led to a significant loss of customers? Suddenly, that $1 million incident starts to look a lot more material to the investor community. It’s a bit like assessing the impact of a sudden spring thunderstorm. Sure, the direct financial losses from property damage and lost productivity are important. But the true measure of materiality lies in how that storm reverberates through the broader ecosystem. Did it disrupt critical supply chains? Did it erode customer trust? Did it trigger regulatory scrutiny and hefty fines?

CISOs need to take a similarly holistic view when evaluating the materiality of a cyber incident. The SEC’s guidelines emphasize the need to consider not just the immediate financial impact, but also the potential for future disruptions, reputational damage, and regulatory consequences. Just like with a natural disaster, investors want to know how the incident will affect the company’s long-term viability and competitiveness.

So how can CISOs weather the cyber storm and keep their organizations afloat? Start by building a robust incident response playbook that aligns with the NIST Risk Management Framework (RMF). Identify the key data points and stakeholder impacts you’ll need to quickly assess the materiality of an event. Engage legal counsel and finance teams to help quantify the potential financial and operational consequences.

Most importantly, don’t wait for the storm to hit before you start planning. Proactively scenario-plan for various cyber incident scenarios, just as you would for natural disasters. Understand the thresholds that would trigger a material disclosure, and work closely with your executive team to ensure everyone is on the same page.

Remember, when it comes to materiality, you’re not just answering to your board or the regulators - you’re accountable to the investors who are putting their trust, and their money, in your organization. By approaching materiality assessments with the same rigor and foresight as you would a natural disaster, you can weather the cyber storm and keep your organization afloat, no matter how strong the winds may blow.
