Testing Cybersecurity Resilience: Insights from Tri-Sector Defense Exercise | Enterra

In the rapidly evolving digital landscape, the significance of robust cybersecurity frameworks

cannot be overstated. For companies like Enterra, understanding the depth and scope of cybersecurity is not just about deploying measures—it’s about developing a sustainable, strategic approach that evolves with emerging threats and technologies. This week’s Tri-Sector Cyber Defense Exercise in Washington, D.C., attended by leading U.S. telecommunications, financial services, and power sectors, including major players like AT&T, Mastercard, and Southern California Edison, underscores a pivotal point in cybersecurity management—the necessity of continuous testing and readiness.


This joint exercise, featuring mixed teams from various sectors defending against and launching controlled cyberattacks, was a real-world application of what we at Enterra refer to as navigating through the Cybersecurity Maturity Model (CMM). Our model emphasizes the importance of assessing current cybersecurity postures to determine how well-equipped an organization is against potential cyber threats. Such exercises are crucial as they not only test existing defenses but also highlight areas needing improvement, providing a clear roadmap from minimal to adaptive stages of cybersecurity maturity.


Testing is essential because it shows where an organization stands on the maturity ladder, helping to identify vulnerabilities and readiness against sophisticated threats. By understanding their current position, organizations can make informed decisions on where to focus their efforts, be it enhancing threat detection systems or integrating advanced security technologies like Endpoint Detection and Response (EDR) or Extended Detection and Response (XDR).


Furthermore, knowing where you stand is crucial in planning how to advance your cybersecurity maturity. This progression is not merely about upgrading technology but also about integrating and streamlining security protocols to ensure they are effective against both current and future threats. It’s about moving from basic defensive measures to a proactive and eventually, an adaptive cybersecurity posture where practices and solutions continuously evolve in response to new challenges.

This proactive approach was vividly demonstrated during the cybersecurity drill, where entities shared tactics and insights, reflecting a collective movement towards a more resilient infrastructure. Mastercard’s cybersecurity expert, Ron Green, likened the collaboration to a band where each sector brings a unique skill—be it financial services playing the guitar or the energy sector leading the vocals. This analogy beautifully captures the essence of multisector collaboration, emphasizing that while each sector may excel individually, facing cybersecurity challenges requires a harmonious and unified approach.


The importance of being aware of emerging threats cannot be overstated. In an era where cyber threats are becoming more sophisticated, the ability to anticipate and neutralize threats before they manifest is invaluable. Our maturity model encourages organizations to not only respond to current threats but also to foresee and mitigate potential future vulnerabilities. This is where the integration of new technologies plays a pivotal role. Tools like Security Orchestration, Automation, and Response (SOAR) and Zero Trust Security are not just enhancements; they are essential upgrades that fortify security architectures against evolving threats.


At Enterra, we are committed to guiding our clients through the complexities of cybersecurity. We understand that the journey through the stages of cybersecurity maturity is a continuous one, marked by constant learning and adaptation. The Tri-Sector Cyber Defense Exercise is a prime example of why hands-on testing and real-world simulations are indispensable. They provide a scenario-based foundation for testing theories and strategies, making them crucial for any organization serious about securing its digital assets.
