This presentation discusses the significance of considering cyber security threats during a PHA/HAZOP. A step-by-step and systematic technique is presented to show how a PHA team could assess the vulnerability of a system or facility to potential cyber threats, analyze adequacy of safeguards, and develop necessary countermeasures to resist cyberattacks. A typical refinery or chemical plant can have thousands of signals that are connected to a Distributed Control System (DCS) to ensure safe and smooth process operation. This arrangement could inadvertently present multiple pathways for malicious parties to intervene by manipulating signals or disrupting communications, potentially leading to severe process hazards and consequences such as a fire, explosion and fatality. Not only does incorporating cyber security in a PHA/HAZOP help identify the vulnerability of your system or facility, it could also be used to prioritize limited resources to ensure critical vulnerabilities are mitigated in a timely and efficient manner. The application of this technique will be demonstrated using case examples.
