Abstract

The invention discloses a DNP3 testing case generation method, a system, a device and a computer medium, which are applied in the DNP3 protocol. The method comprises the following steps: obtaining application layer data, wherein the application layer data is data encapsulated by a data object to be mutated according to the application layer specification of the DNP3 protocol;locating the data objects to be mutated in the application layer data; determining a field to be mutated in the data object to be mutated; the mutation is performed on the mutated fields to obtain mutated application layerdata; according to the transport layer specification of DNP3 protocol, the application layer data is encapsulated into transport layer data. The transport layer data is encapsulated into the data link layer data according to the data link layer specification of the DNP3 protocol. The invention discloses a DNP3 test case generation method, a system, a device and a computer-readable storage medium,which ensure that the data of a data link layer must conform to the DNP3 protocol and contain fields to be mutated, and improves the generation accuracy of the DNP3 test case generation method.

Description

technical field [0001] The present application relates to the technical field of DNP3, and more specifically, relates to a DNP3 test case generation method, system, device and computer medium. Background technique [0002] SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring system) is widely used in oil and gas regulation, petrochemical refining, water conservancy dispatching, rail transit and other fields. With the development of industrial technology and information technology, SCADA systems and SCADA systems and other Interconnection between networks begins, and the communication protocols used include the DNP3 protocol. Although the DNP3 protocol has a certain degree of reliability, this reliability is at risk under the attack of hackers or malicious damage to the control system. In order to reduce this risk, it is necessary to generate test cases based on the DNP3 protocol, and then apply the test cases to analyze the possible vulnerabiliti...
