Don C. Weber helps defenders safely prove security where it matters most in industrial operations. He is a SANS Principal Instructor, CEO and Founder of Cutaway Security, and a Security Solutions Senior Consultant for AI Security at World Wide Technology (WWT). He co-authors SANS ICS613: ICS/OT Penetration Testing & Assessments and teaches SANS ICS410: ICS/SCADA Security Essentials to students around the world. He turns years of field work into step-by-step labs and planning methods teams can use right away.
Don's career runs from hands-on operations to enterprise leadership in cybersecurity management, incident response, vulnerability management, and assessments across energy, manufacturing, and the public sector. That experience shapes how he teaches ICS410. He grounds core security concepts in engineering workflows, safety, and uptime to bridge the gap between IT and OT. Teams leave knowing how to apply these concepts as part of IT/OT convergence. In ICS613, he shows how to scope and plan safer tests, select techniques that fit the process, gather evidence without disruption, and turn results into fixes teams trust.
At WWT, Don secures enterprise AI and agentic systems through threat modeling, architecture reviews, and adversarial testing. This work builds toward a clear goal: protecting AI model development, deployment, and operations in industrial environments.
A longtime contributor to the ICS/OT community, Don creates and shares cybersecurity tools and techniques. His open-source assessment and data processing tools are available on the Cutaway Security GitHub. These include CHAPS (Configuration Hardening Assessment PowerShell Script) for configuration collection on isolated Windows servers and workstations. Don has presented his research at SANS ICS Summit, Black Hat, DEF CON, S4, NRECA, AFCEA TechNet, B-Sides, and other industrial conferences. Topics range from smart-meter security to practical ICS testing workflows. He also participates in ASTM F24 and ISA/IEC 62443 working groups that align safety and cybersecurity requirements. Don is a faculty member of the SANS Technology Institute, an NSA-designated Center of Academic Excellence in Cyber Defense and multi-year winner of the National Cyber League competition.
Don is a U.S. Marine Corps veteran who brings a mission-first calm to the classroom. He focuses on outcomes students can put to work immediately. He emphasizes safe, purpose-built testing, precise communication with engineers and operators, and improvements that respect safety and uptime. Whether students work in energy, manufacturing, water, government, or the public sector, they leave with repeatable ways to scope and execute assessments, choose techniques that fit the process, and turn findings into fixes teams trust. At the heart of his work is a simple aim: help practitioners protect essential services and the communities that rely on them.
The instructor, Don, was great. He communicated well and elaborated on the objectives.
Don is a great instructor and does a fantastic job of leveraging his experiences and backgrounds to extend the course materials. He also ensures that students are getting the concepts to get the most out of the training.
[Don] is very knowledgeable in the field, he's very interactive with the class, and he encourages interaction.

This talk demonstrates the technique on a real PLC. Don C. Weber will show what the AI produced, what it got right, and what it cost. The answer is about one analyst workday and a few dollars in API fees.

Industrial environments are different—and so is the approach required to assess them safely and effectively.

The SANS ICS613 course will be designed to help students understand the tactics and techniques necessary to scope and conduct ICS penetration tests and security assessments. This presentation will review an outline of the content and provide insight into the equipment and labs that students will use to perform hands on learning. Don, one of the course authors, will be available to answer questions about the course, the challenges of testing operational environments, and to outline a path towards conducting safe and effective assessments and security research.

This presentation will review cybersecurity considerations when planning safe operations. Attendees will be introduced to the ISA 62443 risk management process and high-level risk assessment data gathering that will fuel their information gathering requirements.

Don C. Weber will discuss his experiences related to the cyber security challenges facing utilities, industrial, and automation industries. He will discuss the challenges he has experienced, outline security assessments of OT environments, and provide insight into common systemic issues. The presentation will include a question-and-answer session to allow attendees to discuss the challenges and resolutions experienced by their own teams.
