System safety analysis is crucial for preventing losses. To prevent losses, modern safety analysis tools need to capture both safety and security-related risks. This work proposes a holistic safety and security analysis framework that considers both the intentional and unintentional causation of risks. At first, the threats to a process system are identified, followed by analyzing the factors that may lead to these threats. Then the mechanisms to neutralize threats using safeguards are discussed. These steps are modelled in a Bayesian network (BN) framework to capture the probabilistic nature of the events and associated factors. The BN model is used to analyze the real-time risk. The proposed framework is used to study four scenarios. A comparison with previous works confirms that the proposed framework provides better understanding and analysis capabilities. This work will serve as a reference point for further development in integrated safety and security analysis.
