Phase (Design/Operation) design, operation (a) The software failure incident in the article can be attributed to design factors introduced during the development phase. The breach in the home affairs department's SkillsSelect platform was a result of a data exposure issue where personal details of migrants and aspiring migrants to Australia were revealed due to a flaw in the system's design. The system stored expressions of interest publicly, allowing users to view sensitive information with just a few clicks, including unique identifiers composed of partial name information and numbers. This design flaw led to the exposure of over 774,000 unique ADUserIDs and other personal details [Article 99712]. (b) Additionally, the software failure incident can also be linked to operational factors. The breach was exacerbated by the operation of the system, as the publicly available app on the home affairs website allowed users to search and access the database containing sensitive information. The misuse or unintended use of the system by allowing public access to such detailed personal information contributed to the severity of the incident. The operational oversight of not identifying the breach internally and the subsequent need to take the platform offline for maintenance further highlights operational shortcomings in handling the situation [Article 99712].
Boundary (Internal/External) within_system (a) within_system: The software failure incident in the article was primarily due to contributing factors that originated from within the system. The breach occurred within the SkillsSelect platform hosted by the employment department, where personal details of migrants and aspiring migrants to Australia were exposed due to a flaw in the system's design. The ADUserIDs, which were unique identifiers composed of partial name information and numbers, were easily accessible, allowing users to view a range of fields including birth country, age, qualifications, marital status, and application outcomes [99712]. The incident was a result of the system's design and implementation flaws, making sensitive information easily accessible within the system itself.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in this case appears to be primarily due to non-human actions, specifically a data breach in the home affairs department's SkillsSelect platform. The breach exposed the personal details of 774,000 migrants and aspiring migrants to Australia due to the platform displaying sensitive information publicly, allowing users to easily access and search through the data [99712]. (b) Human actions also played a role in this software failure incident. Privacy experts criticized the department for its poor track record in handling personal information, citing previous blunders such as the My Health Record, robodebt, and the 2016 census. Additionally, experts pointed out that the presence of ADUserIDs in the system appeared to be a mistake or a "stuff-up," indicating a potential oversight or error in the system design or implementation [99712].
Dimension (Hardware/Software) software (a) The software failure incident in the article was not directly attributed to hardware issues. The incident primarily revolved around a data breach in the SkillsSelect platform hosted by the employment department, which exposed the personal details of migrants and aspiring migrants to Australia [99712]. (b) The software failure incident in the article was related to a data breach in the SkillsSelect platform, which was hosted by the employment department. The breach allowed unauthorized access to sensitive information of applicants, including their ADUserIDs, birth country, age, qualifications, marital status, and the outcome of their applications. This breach was a result of a flaw in the software system that stored and displayed this information, making it accessible to users who could manipulate filters to reveal detailed personal data of individuals [99712].
