Abstract

The invention discloses a method and device for identifying failure modes of software, and relates to the technical field of the internet. The method comprises the steps that a preset requirement model of the construction software is divided into a software external interface model, a software function model, a software working state model and a software system dependence relation model; the independent function failure mode of the software, the function combination failure mode of the software and the state transition failure mode of the software are analyzed on the basis of the models; software failures caused by software working state conversion and multiple function combinations are fully embodied, the software failure modes can be analyzed comprehensively, and the method has the advantages of being universal, easy to popularize and capable of being copied. Therefore, real causes and potential threats of the software failures are found in the software development process, the improvement of the safety design level in the software development stage is effectively promoted, the pertinence and the effectiveness of correction measures are enhanced, the safety of software products is improved, and the equipment damage caused by the software failures and the cost of the life cycle of the software are reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a software failure mode identification method and device. Background technique [0002] Today's new generation of military equipment systems has become a typical software-intensive system, and its configured software has a significant impact on safety and mission completion. At the same time, system security problems caused by software failures are increasing day by day. According to statistics, failures caused by software in modern military equipment have accounted for more than 70% of the total number of failures. Once the safety-critical software fails or fails, it will lead to the failure of the task at least, and the damage of equipment or even casualties at the worst. [0003] Therefore, in the software development process of military equipment, software security has been the focus of attention, and a series of security standards have been released. The security stand...
