A Control Hazard and Operability Study (CHAZOP) is a procedure for analyzing the safety and reliability of existing or planned Control and Computer systems. A CHAZOP can be performed to support the overall process hazard analysis or to determine the reliability of the control system. Additionally, the CHAZOP represents a key opportunity for aligning functional safety and cybersecurity objectives. By pairing the CHAZOP with a cybersecurity High-Level Risk Assessment (HLRA) the safety, reliability, and security of the control system can be evaluated o support strategic decision making. This webinar will provide a general overview of the CHAZOP and HLRA methodologies along with examples that demonstrate the various approaches that can be taken and the advantages of aligning the CHAZOP study with a HLRA.
