{\bf CRITICAL INFRASTRUCTURE PROTECTION XVI} Edited by: Jason Staggs and Sujeet Shenoi The information infrastructure---comprising computers, embedded devices, networks and software systems---is vital to operations in every sector: chemicals, commercial facilities, communications, critical manufacturing, dams, defense industrial base, emergency services, energy, financial services, food and agriculture, government facilities, healthcare and public health, information technology, nuclear reactors, materials and waste, transportation systems, and water and wastewater systems. Global business and industry, governments, indeed society itself, cannot function if major components of the critical information infrastructure are degraded, disabled or destroyed. {\bf Critical Infrastructure Protection XVI} describes original research results and innovative applications in the interdisciplinary field of critical infrastructure protection. Also, it highlights the importance of weaving science, technology and policy in crafting sophisticated, yet practical, solutions that will help secure information, computer and network assets in the various critical infrastructure sectors. Areas of coverage include: \begin{itemize} \item Themes and Issues \item Industrial Control Systems Security \item Additive Manufacturing Systems \item Infrastructure Device Security \item Telecommunications Systems Security \end{itemize} This book is the sixteenth volume in the annual series produced by the International Federation for Information Processing (IFIP) Working Group 11.10 on Critical Infrastructure Protection, an international community of scientists, engineers, practitioners and policy makers dedicated to advancing research, development and implementation efforts focused on infrastructure protection. The book contains a selection of eleven edited papers from the Sixteenth Annual IFIP WG 11.10 International Conference on Critical Infrastructure Protection, which was held virtually in the spring of 2022. {\bf Critical Infrastructure Protection XVI} is an important resource for researchers, faculty members and graduate students, as well as for policy makers, practitioners and other individuals with interests in homeland security. {\bf Jason Staggs} is an Adjunct Assistant Professor of Computer Science at the University of Tulsa, Tulsa, Oklahoma, USA. {\bf Sujeet Shenoi} is the F.P.
