Gus Serino worked at a large water utility before joining Dragos in 2019. We're talking water sector so it's obligatory to start with Oldsmar (2:20), but we don't talk cyber. Instead we go through the physical portion of the water system assuming the attacker is able to issue the command to the pump to dump a lot of sodium hydroxide into the water system and what would likely happen. Importantly Gus identifies the simple, unhackable solution to this threat. A hard wired PH sensor that will shut off the pump regardless of the commands from the ICS. After Oldsmar Dale and Gus discuss: how small and medium water systems should approach cyber risk the greater challenge to large water systems the EPA's early steps on cybersecurity and future regulation - surprises in moving from a water utility to Dragos what Gus's new I&C Secure company is doing

Dale Peterson interviews acting CISA Director Nick Andersen. They briefly begin with the impact of the personnel changes at CISA, both at the leadership level and widespread exodus of anyone involved in OT. What are the plans for the rebuild of OT capabilities. The bulk of the discussion is on the need, implementation, and metrics related to CISA's ruthless prioritization of efforts and resources. What CISA and US critical infrastructure must do, and what they won't have the resources to do.
It's great to have my friend Rob Lee back on the podcast. Rob and I discuss:
Few topics get as much heat as the current, future, and ideal relationship between OT and IT. One of the first posts someone just discovering OT makes is how OT is different than IT. As you dig deeper into OT you find an increasing case of the technology, processes, and even the people being similar to IT. In this 90 minute long conversation format, we will try to bring some enlightenment to this question with a specially curated group of 9 S4x25 attendees.
Dale Peterson discusses with Maggie how she got into OT security, her recent move to the Financial Sector, women in ICS security, and more.
