About Nick Tsamis: Nick currently serves as Department Chief Engineer within the Cybersecurity Infrastructure Protection Innovation Center (CIPIC) at The MITRE Corporation where he works to develop strategies for protection against emerging threats on critical infrastructure. Nick led the technical efforts for the first release of Caldera for OT. He holds degrees in computer science and aerospace engineering, and resides in Honolulu, HI.
In September, MITRE and CISA announced that MITRE Caldera™ for OT is now publicly available as an extension to the open-source Caldera platform, allowing security teams to run automated adversary emulation exercises that are specifically focused on threats to operational technology (OT).
Our nation’s critical infrastructure—including public transportation, commerce, clean water, and electricity—relies on operational technology, but that technology often has weak security spots. Caldera for OT empowers security teams with new tools to help ensure the safe and secure function of critical infrastructure, thus improving our nation’s resiliency posture.
Caldera for OT is now available on GitHub. As an open-source platform, Caldera for OT will continue expanding to new environments, protocols, and attacks. MITRE partnered with CISA through the HSSEDI (Homeland Security Systems Engineering and Development Institute) to develop the first set of modules and continues to work internally, with CISA, and other organizations to develop and release the next set of Caldera for OT open-source modules.
In this episode, Aaron and Nick Tsamis discuss:
- Creating a common vernacular and building risk-appropriate solutions
- Standardizing cybersecurity practices in OT environments
- Enhancing OT security through customized Red Team assessments and protocol familiarization
- Navigating the intersection of human expertise and machine learning in cybersecurity

Are You A Charlotte?
In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
