Abstract

The invention provides a network protocol safety test method and device, electronic equipment and a storage medium. The method comprises the following steps: establishing a plurality of protocol models of a plurality of protocol layers of a protocol set based on an original message of the network protocol set; generating a plurality of variation messages according to the plurality of protocol models and variation strategies; sending the variation message and the background flow message to the equipment to be tested; and monitoring a transmission process of the to-be-tested device in receivingthe variation message and the background flow message so as to judge whether the to-be-tested device is safe or not.

Description

technical field [0001] The application relates to the technical field of electric power engineering automation communication, in particular to a network protocol security testing method and device, electronic equipment and a storage medium. Background technique [0002] With the widespread use of smart substations, smart substations have become the main targets vulnerable to network attacks. [0003] The protocol used in the secondary system of the smart substation is mainly the IEC 61850 standard, which specifically includes the SV message (Sampled Value, sampled value), the GOOSE message (Generic Object Oriented Substation Event, a generic object-oriented substation event), and the MMS message ( Manufacturing Message Specification, Manufacturing Message Specification). These protocol messages are transmitted in plain text, and are easy to be intercepted, tampered with, forged and replayed. Once attacked, it may lead to secondary system paralysis or primary equipment fail...
