Current OT cybersecurity budgeting approaches reflect a misalignment of prioritizing surface-level defenses over architectural shortcomings. Instead, CISOs should demand vendors deliver products that are secure by design, and address systemic failures over a reactive approach to the security of cyber-physical systems.

Gentry Lane, founder of Nemesis Global, joins the Nexus Podcast to discuss how a Cold War tactic known as Salami Cuts is being used against U.S. critical infrastructure. Adversaries who cannot operate on equal footing on a kinetic battlefield, are finding cyberspace to be a level playing field. The use of salami tactics is a strategy of gradually degrading an opposition's dominance by instilling distrust in institutions, utilities, or the government's ability to protect us.

In this episode of the Nexus Podcast, Pedro Umbelino, Principal Research Scientist at Bitsight Technologies, joins to discuss his team's research into Automatic Tank Gauge (ATG) systems and how they uncovered 11 vulnerabilities in ATGs manufactured by five different vendors. ATG devices have sets of sensors that measure and record fuel levels, condensation, temperature, and volume in storage tanks. They are critical because they can be used to monitor for leaks, and can trigger alerts, sirens, perform emergency shutoff procedures, or allow for ventilation if necessary.
