Vulnerability and Security Risk Assessment of a Thermal Power Plant Using SVA Technique

The philosophy behind the creation of every organization is bound up with the objectives for each it has been created. There are always factors threatening the continuation of the organization’s activities or even its existence. Some of these factors involve common threats in the security area which should be identified, assessed and controlled through a systematic risk management pattern. In the present study, Security Vulnerability Assessment (SVA) technique and a local version of SVA-Pro software called Joshan-Pro was used to estimate the vulnerability and security risk of a combined cycle power plant. In this Plant, 17 assets were identified and among them, 13 assets with higher priority were entered into Joshan-Pro software for further detailed analysis. Gas oil storage tanks with the vulnerability of 2.33 out of 5 and security risk of 46.60 out of 125 were identified as the most important asset in terms of security and the 230 kV substation with the vulnerability of 0.96 and security risk of 8.64 were labeled as asset with the lowest security risk in the plant. The results showed that Joshan-Pro software, using expert’s opinion, has acceptable capability to determine the security vulnerability of the infrastructures.
