Software Taxonomy of Faults

Category Option Rationale
Recurring unknown The articles do not provide information about a software failure incident happening again at either one specific organization or multiple organizations.
Phase (Design/Operation) design, operation (a) The article discusses concerns and potential vulnerabilities related to Microsoft's Secure Boot technology, particularly in the design phase. Linus Torvalds mentions that clever hackers could bypass the encryption keys set up by Microsoft, indicating a potential flaw in the design of the system [12718]. (b) The article also touches upon the operation phase, where Matthew Garrett, a Red Hat engineer, believes that while Secure Boot may be broken, Microsoft will ultimately keep hackers at bay. This suggests that operational factors and Microsoft's response to potential breaches play a role in the system's operation [12718].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident related to the Secure Boot technology discussed in the articles can be considered as a failure within the system. The concerns and discussions revolve around the implementation of Secure Boot by Microsoft, potential vulnerabilities within the system, the need for encryption keys, and the efforts made by Linux distributors like Red Hat to work within this system [12718]. Linus Torvalds and other experts discuss the potential for hackers to bypass the key issue within the system, indicating that the failure risks are internal to the Secure Boot technology itself. (b) outside_system: On the other hand, the articles also touch upon aspects that could be considered as contributing factors originating from outside the system. For example, there are mentions of concerns about Microsoft's attempts to keep Windows relevant in a changing technological landscape, the broader context of the industry, and the potential implications of Secure Boot on Linux distributions like Fedora [12718]. These external factors influence the discussions around the software failure incident but are not the primary focus of the failure itself.
