Tesla said that the car network has completely changed the human life, allowing remote access to be realized, but it also makes the system maintenance more difficult. It is possible to discover new vulnerabilities at any time, not only in the product production cycle, but also after the product leaves the factory. Sloppy. According to reports, traditional software development tends to be passive, and everything waits until the software is developed before testing whether there are loopholes, but in fact does not meet the functional standards such as ISO 26262. After all, the security factor of the networked device should be taken into consideration from the early stage of development. .
In addition to the program code and its subsequent testing, each stage implies design, development and testing, including Unified Modeling Language (UML) design, coding specifications, unit testing, program code coverage analysis, etc. The principle runs through the entire process, and each stage is accurately compared with the previous and subsequent stages. Once there is any need to adjust, automated two-way tracking will automatically detect the adjusted impact, with automatic test analysis as a response. There are any loopholes in the networked device, and it is absolutely necessary to start the whole body. At this time, it is necessary to distinguish between the necessary measures and the functions to be performed by the automatic test. It can be seen that the network changes the end of the R&D process.
In other words, any new vulnerabilities discovered at the factory must be immediately strained, so automated requirements traceability is gaining attention to track demand conditions throughout the product lifecycle and after the product leaves the factory, ensuring that each requirement is linked to operational and project objectives. .
