Critical Infrastructure: You Get What You Pay For
![](https://www.jinfowar.com/sites/default/files/default_images/jiw_article_preview.png)
Abstract:
Programmable Logic Controllers (PLCs) have proliferated into multiple commercial sectors, including critical infrastructure applications. PLCs often manage resources that offer high-impact targets but with a lackadaisical treatment of security—a recipe for trouble. This paper proposes a misuser-driven approach for PLC assessment. The technique is a negativist spin on the user-story-driven software engineering approach of agile development. The paper presents a case study approach by examining a commercially available low-cost PLC; it also highlights the investigational process and describes the specific vulnerabilities uncovered by the process.

Dr. Matthew L. Hale is an Assistant Professor of Cybersecurity in the School of Interdisciplinary Informatics at the University of Nebraska at Omaha. He received his PhD in Computer Science from the University of Tulsa in 2014. His dissertation created a framework and interlingua for web service security certification in the cloud. His research interests lie at the intersection of software engineering and security with foci in the areas of building secure web services, evaluating internet of things devices and services, and investigating security problems in the context of human psychology. In his spare time, Dr. Hale enjoys cooking, which he thinks isn't all that different from software engineering (components, connectors, and patterns), disc golfing, and tabletop games.
