Cybersecurity, Critical Infrastructure, & RF - layer Threats
About Me
I'm Norris Cornell, a cybersecurity professional focused on the spaces where traditional security domains collide—Industrial Control Systems, Application Security, and Signals Intelligence. I'm particularly interested in satellite cybersecurity and the RF-layer vulnerabilities that most security teams don't see coming.
Background
My path wasn't typical. I spent nearly 20 years as an electronics technician working with specialized instrumentation before transitioning into cybersecurity. That hands-on background with physical systems gives me a different perspective on how cyber-physical infrastructure works—and fails.
I went back to school and earned my M.S. in SCADA Cybersecurity from Wilmington University, competed as a blue teamer in cyber defense competitions, and built expertise in protecting critical infrastructure.
Currently, I'm Technical Lead on a core banking system modernization project in the financial sector, managing identity and access for 700+ users across integrated applications. The work involves PCI DSS compliance, AI-enhanced data validation, and keeping mission-critical systems secure while we transform them.
Research & Speaking
In 2025, I presented "When Cyber Meets the Spectrum" at BSides Delaware, exploring how satellite communications create cybersecurity blind spots at the RF layer. I examined real-world incidents like the Viasat KA-SAT attack and GNSS spoofing, showing how attacks that start in the spectrum can cascade into SCADA systems and critical infrastructure.
Most of my research centers on threats that don't fit neatly into traditional security categories:
-
Satellite cybersecurity and RF-layer attack surfaces
-
How GNSS timing vulnerabilities affect industrial control systems
-
The intersection of signals intelligence and operational technology
-
Identity and access management at scale in high-compliance environments
I write about this stuff here because I think these convergence points—where IT security, OT security, and RF security overlap—are where the most interesting (and dangerous) blind spots exist.
Let's Connect
If you're working on similar problems, researching these areas, or just want to talk about satellite security, SCADA, or the spectrum in between, reach out. I'm always interested in connecting with people tackling these cross-domain challenges.
