Mounting OT cyber risks demand stronger cyber-physical security to protect legacy systems and operational continuity: IndustrialCyber.co
John Cusimano, chief strategy officer (CSO), was recently featured in IndustrialCyber.com for a discussion of legacy OT environments and their unique challenges.
Legacy CPS often lack modern security controls, yet they perform safety-critical functions that cannot be interrupted. The solution lies in adopting a cyber-safety engineering approach that integrates safety and cybersecurity risk assessments.”
He added that methodologies like Cyber PHA or Cyber HAZOP, based on ISA/IEC 62443-3-2, enable cross-functional teams to collaboratively identify and mitigate cyber risks that could impact safety. “This structured, consequence-based process allows defenders to prioritize mitigations that preserve operational integrity while incrementally improving security posture. Collaboration between safety and cybersecurity professionals is essential to balance real-time safety demands with long-term security goals.”
