Boundary (Internal/External) within_system, outside_system The software failure incident reported in the article [10749] involves a potential data security issue with Microsoft's Xbox 360. The incident boundary can be analyzed as follows: (a) within_system: The failure is related to the Xbox 360 system itself, particularly concerning how the console handles user data after being restored to factory settings. Researchers found that personal data, including credit card information, might still be accessible even after the device has been reset. This indicates a flaw within the system's data handling mechanisms. (b) outside_system: On the other hand, Microsoft's response to the researchers' findings suggests that the company does not believe credit card data is stored locally on the console and questions the validity of the claims. This external perspective from Microsoft challenges the researchers' assertions and implies that the issue may not be originating from within the Xbox system but could be influenced by external factors or misunderstandings about how the system operates.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in the article is related to non-human actions. The issue arises from the Xbox 360 potentially not properly protecting user data after the console is restored to factory settings. Researchers at Drexel University discovered that personal data, including credit card information, might still be accessible to malicious hackers even after the device has been reset. This failure is attributed to the software not completely wiping the data from the hard drive, leaving it vulnerable to exploitation [10749]. (b) The software failure incident is not directly linked to human actions causing the failure. However, human actions, such as trading in consoles or using modding software, can inadvertently expose the vulnerability in the software's data protection mechanisms. The incident highlights the importance of proper data handling practices by users, such as removing the hard drive and using third-party tools for secure formatting [10749].
Dimension (Hardware/Software) hardware, software (a) The software failure incident related to hardware: The incident reported in the article [10749] involves a potential security vulnerability in Microsoft's Xbox 360 console when it comes to protecting user data after the console is restored to factory settings. Researchers at Drexel University discovered that personal data, including credit card information, might still be accessible on the hard drive even after a reset. This issue is related to the hardware aspect of the Xbox 360 console, specifically the hard drive, which may not be completely wiped of user data during the restoration process. (b) The software failure incident related to software: On the software side, Microsoft's response to the researchers' findings suggests that the Xbox console is not designed to store credit card data locally on the console. Microsoft's security general manager mentioned that they have processes in place to wipe the local hard drives of any other user data when refurbishing used consoles. This discrepancy between the researchers' claims and Microsoft's statements points to a potential software-related issue in how data wiping and security measures are implemented on the Xbox 360 console.
