Welcome to Part IV of our blog post miniseries on The Quest for SBOMs and the Legend of the SBOM'd Substation. We continue this week with the fourth installment from this series, inspired by the epic S4x24 main-stage presentation delivered by Matt Wyckhouse, Founder & CEO of Finite State, and Alex Waitkus, Principal Power Delivery Cybersecurity Architect at Southern Company.

Entering the Vulnerability Valley
As our adventurers pressed deeper into the digital ecosystem's labyrinth, they encountered the foreboding "Vulnerability Hoard" - a realm where not all monsters are what they seem. With vulnerabilities hidden among the software components listed in the SBOMs, our cybersecurity adventurers, armed with a scanner tool and magnifying glass, embarked on a quest not just to identify these threats but to discern real dangers from mere illusions.
The Tools of the Trade
As one member of our group highlighted the precision of our software composition analysis, a vigilant sentinel that flags any potential vulnerability, another reminded us that not all flagged threats pose a real danger in our specific context. Thus, wielding threat intelligence and leveraging EPSS and CVSS rankings became crucial in isolating the true monsters - the vulnerabilities with the potential to unleash chaos.
Finite State and platforms of its ilk emerged as invaluable allies, refining our focus on strategic defense over a blanket security approach. Despite the vast hoard, the determination to confront only the most formidable foes underscored our narrative.
The Trek Through Vulnerability Valley
Navigating the valley proved a daunting endeavor, awash with both real and illusory threats. The journey was akin to traversing a treacherous landscape filled with "VEX Prayers" and "Naming Woes," each signpost a testament to the challenges of vulnerability overload. With thousands of potential adversaries and the reality of vulnerability management's daunting scale, the need for strategic prioritization was clear.
Escaping to the Exploitability Enclave
The transition from the overwhelming hoards to the "Exploitability Enclave" marked a pivotal shift in our quest. Here, the VEX documents, akin to a shield in the melee, helped slice through the chaos, guiding our heroes to the vulnerabilities that truly mattered. Yet, this reliance on vendor-provided exploitability assessments was a double-edged sword, imbuing our journey with both clarity and caution.
Triaging Towers: The Art of Discernment
At the heart of our odyssey was the "Triaging Towers," where the essence of our mission crystallized - sifting through the myriad threats to pinpoint those warranting immediate action. This phase underscored the criticality of independent verification, transforming vendor assessments from gospel to guideposts, necessitating a nuanced approach to navigating the vulnerability landscape.
The Side Quests: Navigating the Real-World Riddles
Our journey was punctuated by side quests that delved into the complexities of SBOM management, from incorrect VEX assertions to the challenges posed by discrepancies between documented and actual exploitability. These case studies served as reminders of the labyrinth's intricacies, highlighting the indispensable value of critical evaluation and third-party verification.
Beyond the Quest: A Glimpse into the Future
As our narrative arc reached its crescendo, the journey from the shadows of the labyrinth to the clarity of a comprehensive digital inventory unfolded as a tale of transformation. The once-daunting task of cataloging our digital domain had morphed into a saga of enlightenment, revealing the very essence of our operational technology.
This was not the end but a "save point" in an ongoing saga of cybersecurity. With a sustainable plan for integrating SBOMs into our defenses, collaborative dialogues with vendors, and the backing of a community of like-minded crusaders, the quest for securing our digital realm was just beginning.
Exiting the Game: A Path Forward
Our journey through the SBOM labyrinth has laid the foundation for future explorations in the realm of operational technology security. With key learnings in hand and a vision for industry-wide collaboration, the quest for a more secure digital ecosystem continues. The game board stretches out before us, not as a challenge completed, but as a vast landscape of opportunities for innovation, collaboration, and strategic defense in the digital age.
