Problems solved by technology
[0006] (2) Lack of establishing and maintaining the tracking relationship between software security requirements and system functional requirements
[0007] (3) In the process of complex system development, information is not disclosed due to restrictions such as contracts
Due to the contractual relationship, there is no standardized expression of the information interface between each other, so that in the process of security requirements analysis, the input is not perfect, resulting in incomplete requirement capture
[0008] (4) Lack of reasonable summary and classification of software security requirements
However, this classification ignores the consideration of safety integrity requirements and design constraints

The invention relates to a method for obtaining software security requirements by module security analysis, comprising: for each subsystem, developing modules according to the requirements for security analysis in the subsystems, and establishing a corresponding security analysis module in a computer terminal ;According to the functional information and design decision information input from the database, conduct safety analysis on the system software or specific software of the subsystem, and generate a hazard analysis model; output software safety function requirements and corresponding design decisions to the requirements development module and design and development modules to form new demand development modules and design and development modules. The present invention establishes an information interface design suitable for multi-organization collaborative development of safety-critical systems; constructs system hazard analysis field model templates with reference to safety-related standards, and supports safety analysts to analyze system hazards and capture specific software safety in a systematic and structured manner sexual needs.
Description
technical field [0001] The invention relates to the technical field of computer software, in particular to a method for acquiring software safety requirements by module safety analysis. Background technique [0002] Software requirements describe the behavior, characteristics or attributes required by the system from the user's point of view, and are the bridge between users and developers. Accurate and complete requirements are the fundamental basis for guiding the subsequent analysis, modeling, development and testing of the system. Especially in the field of aviation, the incomplete capture of safety requirements for airborne software may cause significant property damage, damage the environment, and even endanger human life. Therefore, it is very necessary and urgent to study the security requirements acquisition of airborne software. [0003] There are certain similarities in the identification process of security requirements defined in existing research and standard...
