Security Architecture Reviews in ICS and OT Environments: A Practitioner’s Guide to Building Your Team

By Alex Teague If you’ve spent any time in industrial cybersecurity, you know that assessing an ICS or OT environment is a fundamentally different discipline from reviewing a typical enterprise network. The stakes are higher, the technology is older and the customer is above all, concerned with protecting the process. Over the years, I’ve led […]

Murky Waters: Why deep IoT and OT Device Vulnerability Research Matters More Than Ever (Part 2)

By Alex Teague Welcome to part two of my blog detailing the process, and implications of deep IoT and OT device vulnerability research. 6. Insecure Remote Access Implementations The proliferation of remote access in OT has introduced a new category of vulnerabilities that sits at the boundary between IT and OT security. Many OT vendors […]
