摘要

近年来,针对工业控制系统(ICS)的网络攻击迅速增加;因此,ICS的网络安全应用和安全评估变得非常重要。技术评估方法(TAM)是由美国电力研究所(EPRI)开发的一种评估和应用电厂安全控制方法的方法。通过应用TAM,可以解决网络安全应用和现有核设施安全评估的局限性。本文以APR1400的某一安全系统为对象,搭建了虚拟试验台,并对TAM进行了应用和分析,得出了TAM的两大优势和五大特点。在此基础上,阐述了将TAM用于核设施安全控制方法的应用和评估的基本原理,包括更好地应用TAM的五个考虑因素。最后,提出了应用TAM的下一步工作。

A Study on the Application of Technical Assessment Methodology (TAM) for CyberSecurity in Nuclear Power Plant
Recently 1, cyber attacks targeting Industrial Control Systems (ICS) have been increasing rapidly; accordingly, cyber security applications and security evaluations of ICS are becoming very important. Technical Assessment Methodology (TAM) is a method developed by the Electric Power Research Institute (EPRI) in the United States for assessing and applying security control methods for power plants. By applying TAM, limitations of cyber security application and security evaluation of existing nuclear facilities are able to address. In this study, a virtual test bed was composed for one of the safety systems of APR1400, and the TAM was applied and analyzed to derive two advantages and five features of TAM. Based on this, the rationale for using TAM for the application and assessment of security control methods in nuclear facilities was explained, including five considerations for the better application of TAM. Finally, we propose future work for applying TAM.
