Abstract
Software security relates to the economy and safety of nuclear power plants (NPPs). Cyber security is a hot research topic for NPPs. The standards and regulations have been established for cyber security in NPPs, such as regulatory guide 5.71. Cyber-attack is a threaten that may be happened at any point during the life cycle of the digital instrumentation and control systems. The vulnerabilities of information security can be reduced by physical protection, independent strategies and administrative measures. The security measures only concern with the cyber security for NPPs in commonly. The essence of digital instrumentation and control systems has not been paid enough attention. Software security is the last line of against the attacker. In this paper, the risk of software security has been analysed for the digital instrumentation and control systems in NPPs. The identification and detection measures have been proposed in the paper.
