255: How AI is Reshaping Security and OT Network Requirements featuring Felipe Sabino Costa, Sr. Product Manager for Networking & Cybersecurity at Moxa

43 minutes

It’s been over a year since we’ve talked about cybersecurity on Manufacturing Happy Hour, and with AI changing the game completely, we’re overdue for a refresh. Around 80-85% of the global industry doesn’t have basic defense at the edge of their networks; that’s a sobering statistic.

Felipe Sabino Costa, Senior Product Manager for Networking and Cybersecurity at Moxa, joins the show to break down why Operational Technology (OT) security matters more than ever.

Manufacturers need to transmit massive amounts of data for AI and predictive analytics, but they’re working with 15–20-year-old infrastructure that wasn’t built for this.

The good news is, Felipe shares practical frameworks like NIST and IEC 62443 (which he compares to nutrition labels) that help manufacturers build security into their operations.

The key takeaway? There's no silver bullet; it's about building layers of defense and finding the right partners.

In this episode, find out:

Why OT data has shifted from historical logging to real-time predictive power
The bandwidth issue hitting intelligent transportation systems and semiconductor manufacturing
How AI enables attackers to adapt their attacks in real-time
Why 80-85% of global industry lacks protection
Felipe's nutrition label analogy for understanding security certifications
The difference between thinking your air-gapped and actually being air-gapped
Why defense requires multiple layers of security
Felipe's outlook on the future of OT networks

Tweetable Quotes:

“We used to be air-gapped or isolated. And many of the companies, they still think that they are, but they are not anymore. To be really air-gapped, I shouldn't have any way to send data.”
“Give and take, 80% of the global industry, including the US, does not have these specific layers of defense. They have some defense, but they have nearly zero protection close to the process itself.”
“There is no silver bullet. We are seeing this shift right from how we used to do security. A strategy should be way more sophisticated.”
