Building management or automation systems are increasingly being connected online. Each connection to the internet introduces a new risk. Attackers looking for an entry point onto an internal network or to disrupt operations within a building could target a vulnerability in an internet-facing system and put the physical safety of occupants—or patients at a hospital, for example—at risk.

Reducing the Cybersecurity Risks of Connected BMS

Alessio Rosas
Ron Fabela joins the Nexus podcast to discuss his research into low-skilled threat actors targeting operational technology and industrial control systems. Many of these groups operate as hacktivists and carry out less sophisticated defacements and intrusions. While less of a risk, these incidents are still a drain on human resources required to investigate them and decided on mitigation strategies.

Brian Foster, senior advisor for grid security at Southern California Edison, joins the Nexus Podcast to discuss his presentation delivered at the S4 Conference on the risks of a hyperconnected grid. Adding a Wi-Fi connection to vulnerable smart meters that are enrolled by customers on a massive scale may allow attackers able to compromise centralized command and control of these devices to issue commands at scale that could result in catastrophic damage.

Accelerating IACS/OT Cybersecurity Improvements

Don C. Weber
In this episode of the Nexus Podcast, CISA ICS Cybersecurity Lead Matthew Rogers discusses new guidance from the agency on the use of security operational technology (OT) protocols, titled “Barriers to Secure OT Communication: Why Johnny Can’t Authenticate.” The paper advocates for the use of secure versions of legacy OT protocols, or the adoption of open standards by OEMs, in order to bring authentication and integrity to OT protocol communication.

Nexus Podcast: CISA on Secure-by-Demand for OT

Michael Mimoso
Five cybersecurity trends for operational technology (OT) figure to dominate in 2025. They include: increased government and regulatory scrutiny on OT, the need for new strategies to secure once air-gapped OT, and OT specialization for CISOs and others in cybersecurity leadership roles.
