As technology becomes ever more integrated into critical infrastructures, recent events have demonstrated the ongoing vulnerabilities in the aviation sector. A prime example is the recent cyberattack on Seattle-Tacoma International Airport (Sea-Tac), which, heading into the busy Labor Day weekend, caused significant disruptions in flight delays, baggage handling, and essential services. This incident serves as a critical reminder of the importance of robust cybersecurity measures, and it's an opportunity to discuss how our Cyber Maturity Model at Enterra plays a role in ensuring the resilience of industries like aviation. The lessons learned from this cyberattack are not only relevant to the aviation sector but can also provide insight into the security frameworks we advocate across industries.
The Sea-Tac Cyberattack: An Overview
Five days before the busy holiday weekend, Sea-Tac detected a cyberattack that crippled its internal technology systems. This led to delays in flight operations, Wi-Fi and flight information outages, and backups in the airport’s baggage handling systems. The Port of Seattle, which operates the airport, responded by implementing emergency measures. However, the airport remained in a state of operational limbo for several days. Notably, major carriers like Delta and Alaska Airlines, which use independent IT systems, were largely unaffected, while smaller airlines such as Frontier, Spirit, Sun Country, and JetBlue, which rely on the airport’s shared technology systems, were hit hard by the outages.
This incident highlights two critical cybersecurity issues for aviation:
The need for redundancy and fallback systems: When critical systems fail, airports need both tested redundancies and manual alternatives that ensure safe operations. Sea-Tac’s reliance on a centralized tech system, used by multiple airlines, created a point of vulnerability.
Inconsistent technology infrastructure across airports: The disparity between airlines using shared tech systems and those with proprietary networks underscores the inconsistent security landscape in the aviation sector.
Cyber Threats in Aviation: The Bigger Picture
Cyberattacks on airports are not new, and they have become more frequent as hackers target vulnerable points in critical infrastructure. Airports, with their interconnected systems and dependence on technology for everything from flight operations to baggage handling, present a prime target. As Jeffrey Troy, President of the Aviation Information Sharing and Analysis Center, noted, the technology infrastructure at airports varies widely across the U.S. This variation can sometimes limit the impact of cyberattacks, as not all systems are interconnected. However, for airports like Sea-Tac, which utilize shared systems for several smaller airlines, the attack led to widespread disruptions.
Enterra’s Cyber Maturity Model and the "16-CI"
At Enterra, we’ve developed a Cyber Maturity Model that aligns with the U.S. government’s framework for critical infrastructure protection. Specifically, our focus on the "16 Critical Infrastructure Sectors (16-CI)"—which include transportation systems like airports—addresses the unique challenges that these sectors face in maintaining secure and resilient operations.
Our model emphasizes four key areas of maturity:
Identification: Establishing a comprehensive understanding of the systems and assets that are critical to operations.
Protection: Implementing strong, multi-layered defenses to prevent cyberattacks.
Detection: Rapidly identifying breaches or system failures through advanced monitoring and AI-driven analytics.
Response and Recovery: Ensuring that, if an attack occurs, systems can recover quickly and continue operations with minimal disruption.
In the case of Sea-Tac, it is clear that there were shortcomings in both the detection and recovery phases. The attack managed to disrupt operations for several days, leading to delays, handwritten boarding passes, and manual baggage sorting. This is where Enterra’s Cyber Maturity Model can provide value—not just to the aviation industry but to any sector within the 16-CI.

Learning from the Sea-Tac Incident: Future Directions
The Sea-Tac incident should serve as a wake-up call for the aviation sector and other industries within the 16-CI. Here are a few insights we can glean:
System Redundancies Are Crucial: As Moses Frost from the SANS Institute pointed out, it is essential for critical systems to have tested redundancies. Airports and other critical infrastructure need to ensure that they can fall back to safe, manual operations when technology fails.
Proprietary Systems vs. Shared Systems: The incident shows that carriers like Delta and Alaska Airlines, which were unaffected by the attack, benefited from their independent IT systems. Smaller airlines, however, were more vulnerable due to their reliance on Sea-Tac’s shared systems. Enterra’s approach to cybersecurity emphasizes the importance of segmented, resilient systems that reduce the risk of widespread disruption.
Focus on Detection and Response: Rapid detection and immediate response are essential in preventing widespread damage from cyberattacks. The Sea-Tac incident could have been mitigated with more robust real-time monitoring and quicker activation of contingency plans.
How Enterra Enhances Cybersecurity for Critical Infrastructure
At Enterra, we specialize in creating cybersecurity solutions tailored to the unique needs of critical infrastructure sectors. Our Cyber Maturity Model helps organizations assess their current cybersecurity posture and provides a roadmap for improvement, focusing on proactive threat detection, AI-driven analytics, and a robust response and recovery framework.
For airports and other transportation hubs, we offer solutions that integrate Internet of Things (IoT) devices with AI-driven monitoring tools to detect and respond to cyber threats in real-time. By leveraging the power of AI and machine learning, our systems can analyze data patterns, predict potential breaches, and alert organizations before a full-blown attack occurs.
In a world where critical infrastructure faces increasing cyber threats, our approach is designed to help organizations within the 16-CI, including transportation systems, energy grids, and public utilities, stay secure and resilient. As we’ve seen from the Sea-Tac incident, being prepared with the right tools and systems is not just a matter of efficiency—it’s a matter of safety and trust.
A Call to Action for Enhanced Cybersecurity in Critical Infrastructure
The recent Sea-Tac cyberattack is a stark reminder of the vulnerabilities that critical infrastructure faces in today’s digital landscape. As cyber threats grow in frequency and complexity, it is essential for organizations, particularly those within the 16 Critical Infrastructure Sectors (16-CI), to take proactive steps toward enhancing their cybersecurity measures. By leveraging AI-driven monitoring, predictive analytics, and segmented systems, we can reduce vulnerabilities and enhance resilience across all infrastructure sectors.
