A method for detecting the safety of electrical equipment

Abstract

The invention provides a method for detecting security of electrical equipment. The method comprises the following steps: detecting whether the electrical equipment has a specified secure communication port function; detecting whether the equipment has a TLS transport layer security function; and detecting whether the equipment has associated authentication and replay attack prevention functions of an MMS application layer. The method provided by the invention is used for detecting whether security equipment about to pull in has security specifications required by the IEC62351 standards to offer suggestions for the inbound of the equipment, and detecting the security function of the equipment after MMS protocol security reinforcement and judging whether the equipment reaches a security reinforcement effect according to the IEC62351 standards, in order to provide guidance basis for the development and inbound of the security equipment; and the cost of directly using the equipment in bound can be effectively reduced, and it is conducive to promote equipment developers to develop security equipment products satisfying the IEC62351 standards.

Description

technical field [0001] The invention relates to the field of electric power information security, in particular to a detection method for the security of electrical equipment. Background technique [0002] The power grid smart substation system is the core of the power grid business system, and the safety evaluation and protection construction of the power grid smart substation system is the internal guarantee for the construction of a smart grid. The safety evaluation and construction of the grid smart substation system is to use advanced evaluation concepts, evaluation methods, and evaluation tools for the safety evaluation of the smart substation system to ensure the safe and stable operation of the power grid. On October 25, 2011, the Ministry of Industry and Information Technology issued the "Notice on Strengthening Information Security Management of Industrial Control Systems" (hereinafter referred to as the "Notice"), requiring that the information security management...

[0004] However, when the DL / T 860 standard was proposed, it only paid attention to the shared communication between IEDs, but did not pay attention to the security in the communication process. As a result, once the substation is invaded, and there are no protective measures inside the substation, the consequences will be very difficult. to imagine
