Two Decades of Defending ICS: The SANS ICS Summit 20th Anniversary!

This blog was jointly authored by Dean Parsons and Tim Conway.

Why the ICS Summit?

The SANS ICS Summit was created to address the growing need for cybersecurity education and training across the industrial control systems/operational technology (ICS/OT) communities. It aims to reach and educate a wide spectrum of professionals involved in industrial cybersecurity.

2025 marks the 20th Anniversary of the SANS ICS Summit! The Summit has evolved significantly over the last two decades, playing a pivotal role in advancing ICS/OT security worldwide. Not only has it kept pace with the changing cybersecurity landscape, but it has also anticipated and shaped the future of security practices and technology. The Summit has trained countless leaders and practitioners to defend critical infrastructure across all sectors.

NEW Format for the 20th Anniversary

This year’s 20^th Anniversary ICS Summit will take place June 15-17 at Disney's Contemporary Resort. The 2025 Summit features an updated three-day format designed to enhance knowledge-sharing hands-on experiences. Attendees will benefit from practical workshops, live demonstrations, and industry expert-led presentations, followed by specialized ICS/OT training courses.

This new format is designed to address modern ICS security challenges and provide real-world, applicable defense strategies for critical infrastructure sectors.

Honoring a Legacy: Mike Assante and the Origins of the ICS Summit

Mike Assante was a highly respected figure in the field of ICS security. His contributions were pivotal in establishing and shaping the SANS ICS Security Summit. Mike served as the SANS lead for ICS and Supervisory Control and Data Acquisition (SCADA) security. His work at SANS Institute embodied his deep commitment to enhancing the security of critical infrastructure against evolving threats.

His work extended beyond SANS, as he held leadership roles at organizations like American Electric Power where he served as Vice President and Chief Security Officer (CSO) and North American Electric Reliability Corporation (NERC) where he served as the first CSO. His research at the Idaho National Laboratory played a crucial role in identifying vulnerabilities in control systems and developing cybersecurity strategies to mitigate them. His legacy includes influencing policies, authoring significant papers on cybersecurity and policy issues, and mentoring many in the field.

The Michael J. Assante ICS Security Lifetime Achievement Award, named in his honor, recognizes individuals who have made exceptional contributions to the security of ICS on an international scale, highlighting his lasting impact on the industry.

A Message from Dean

On a personal level, being involved in cyber defense for over 20 years—more than half of that in ICS/OT sectors—I am deeply honored to continue contributing to defending critical infrastructure. Whether through writing the ICS Cybersecurity Field Manual, creating whitepapers, posters, blogs, and instructional videos, or leading training initiatives globally, my mission has always been to empower others with practical knowledge and strategies they need to secure the systems that underpin modern society.

My journey has been profoundly shaped by hands-on experiences, collaborations, and the community spirit fostered by the SANS ICS Summit—a hub for hands-on, practical ICS/OT cybersecurity. From countless conversations with industry peers to invaluable opportunities to work directly with ICS/OT technologies across many sectors, these experiences have solidified my belief and the importance of the SANS ICS mission: the ongoing protection of our critical infrastructure.
