This gap suggests that leadership assumptions about OT resilience are not being validated through hands-on technical testing or realistic tabletop exercises. Meanwhile, a 1.7x year-over-year rise in ICS\u002FOT incidents combined with slower detection times means threats are growing faster than defensive capabilities. When leaders don't engage with the technical realities their engineers face, critical gaps in business continuity planning go unaddressed until a real incident exposes them catastrophically.","**Immediate actions:**\n- Conduct joint tabletop exercises that include both CISOs and plant engineers to surface realistic capability gaps in manual operations.\n- Establish a baseline measurement of how long each critical OT process can sustain safe production manually without digital systems.\n\n**Long-term improvements:**\n- Require routine technical resilience testing (red team, drills, failover tests) with results reviewed by both engineering and executive leadership.\n- Develop and regularly update OT-specific business continuity and incident response plans co-authored by engineers, not just security leadership.\n- Invest in OT-specific detection tooling and reduce mean time to detect by setting measurable SLAs tied to ICS\u002FOT monitoring.\n\n**Detection & governance measures:**\n- Implement formal feedback loops so engineering-level incident observations are escalated and factored into executive risk assessments.\n- Track and report ICS\u002FOT incident metrics (frequency, detection time, containment time) at the board level to close the perception gap.",[12,13,14,15,16],"NIS2 Article 21(2)(c)","NIS2 Article 21(2)(f)","NIST CSF 2.0 GV.RM-06: Risk Management Strategy","NIST SP 800-53 CP-4: Contingency Plan Testing","NIST CSF 2.0 DE.CM-01: Monitoring",{"NIS2 Article 21(2)(c)":18,"NIS2 Article 21(2)(f)":19,"NIST CSF 2.0 DE.CM-01: Monitoring":20,"NIST SP 800-53 CP-4: Contingency Plan Testing":21,"NIST CSF 2.0 GV.RM-06: Risk Management Strategy":22},"This point requires organizations to maintain business continuity and crisis management plans, directly addressing the finding that plants cannot sustain safe manual operations for 48+ hours during a cyberattack.","This point requires assessing the effectiveness of cybersecurity measures, which the survey shows is failing because leadership is not conducting routine technical testing to validate OT resilience claims.","This category requires continuous monitoring of systems to detect adverse events, directly relevant to the survey's finding of slower ICS\u002FOT detection times and inadequate monitoring practices.","This control requires organizations to test contingency plans through exercises and drills, the absence of which allowed leadership to hold unfounded assumptions about OT continuity capabilities.","This category calls for risk assumptions to be validated and communicated across the organization, which would have surfaced the disconnect between CISO confidence and engineer-assessed operational reality.","published","2026-11-12T06:20:18.803407+00:00","2026-11-12T06:20:18.783+00:00",{"id":7,"url":27,"slug":28,"title":29},"https:\u002F\u002Fwww.helpnetsecurity.com\u002F2026\u002F11\u002F12\u002Fsans-industrial-cybersecurity-survey\u002F","cisos-say-ot-will-survive-a-cyberattack-but-their-engineers-aren-t-so-sure-f52c32","CISOs say OT will survive a cyberattack, but their engineers aren’t so sure",[31,37],{"id":32,"name":33,"slug":34,"description":35,"color":36},"182e11d5-57c4-444e-8ec8-4682ad60261b","Incident Response","incident-response","Slow detection, poor containment, missing playbooks","#14b8a6",{"id":38,"name":39,"slug":40,"description":41,"color":42},"7261eb8f-acd4-4d93-a489-7fdd652ec0ea","Security Awareness","security-awareness","Phishing, social engineering, human error","#22c55e",[],[45,49,53],{"slug":46,"name":47,"problem":48},"breach-attack-simulation","Breach and attack simulation","You only find out whether your security tools stop an attack when a real attacker tries.",{"slug":50,"name":51,"problem":52},"ot-security","OT and industrial control system security","Factory, building and utility control systems get visibility and protection.",{"slug":54,"name":55,"problem":56},"incident-response-retainer","Incident response retainer","Experts are on call before the worst day, not searched for during it."]
