Cyber Hazard and Operability study (cyber HAZOP) is a safety-based cybersecurity risk assessment on Industrial Automation and Control Systems (IACS): Operational Technologies (OT), Basic Process Control Systems (BPCS), and Safety Instrumented Systems (SIS). It is a systematic analysis of deviations, consequences, safeguards, and risk-reduction actions aligned with industry standards ISA/IEC 62443 , ISA/IEC 61511, and NIST Special Publication (SP) 800-39 . Cyber HAZOP integrates IT and multiple engineering d
Cyber HAZOP methodology is an extension of the Hazard and Operability study (HAZOP). Chemical, mining, oil and gas, and nuclear industries utilize HAZOPs for a systematic examination of potential process hazards and operability problems.
Cyber HAZOP applies a unified cybersecurity approach to securing SIS, which are the last line of defense against catastrophic accidents. SIS detect dangerous conditions and return hazardous processes to safe operating levels or initiating their shut down.
