INSIGHT

OT Security Requires Safety‑First Mindset

  • Ben Worthy explains Airbus Protect works across aviation, nuclear, water and energy where cyber incidents can cause kinetic harm, so safety and security must speak the same language.
INSIGHT

IT Attacks Can Paralyze OT Via Convergence

  • IT/OT convergence means IT-targeted attacks can halt physical operations without directly touching PLCs.
  • Examples like MES or ERP losing connectivity can stop manufacturing even if OT controllers remain uncompromised.
ADVICE

Prepare Incident Plans And Test Them Regularly

  • Prepare for incidents assuming they will happen by building and testing incident response and resilience plans.
  • Ben Worthy recommends identifying critical assets, mapping dependencies and testing plans including third parties to ensure quick recovery and continuity.
