With the integration of information technology and industrialization development,the nuclear power plant’s information security has become increasingly important.The cyber system brings some hidden danger because of its inherent vulnerability.So it is significant to assess the vulnerability of cyber system,to determine the risk and the weak parts of power industry,and to set appropriate response for the potential accidents of the cyber system.Starting from the point of view of the nuclear power industry information security,this paper describes the virus invasion means and protection methods,information system risk assessment steps and measures in the industry control systems in accordance with IEC 62443 standard,with the widespread use of nuclear power plant probabilistic safety assessment method.Finally,it describes the risk assessment as an important condition for the protection of the cyber security of nuclear power.
