Application of GB/T20984 in Electric Power Information Security Risk Assessment

With the developing of the electric power automation level, the power system depends on the power information network protecting its safety, reliability and efficiency increasingly. As electric power information system achieves networking, their entire network´s security also faces enormous risks. Any security problems from this information network are likely to affect power system security, stability and economic operation, thereby affecting the reliable power supply and people´s daily lives. On the basis of the electric power information network, this paper has designed an electric power information security risk assessment which is based on GB/T20984-2007 Risk Assessment Specification for Information Security. The assessment is divided into expert assessment client, assessment management client, information database management client and questionnaire management client.
