Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident related to a breach of computer networks at Broward Health in southeast Florida did not involve ransomware and did not disrupt patient care. The breach occurred through a third-party medical provider, highlighting the exposure that hospitals and organizations have to hackers via their supply chains. This incident at Broward Health is an example of a software failure within the same organization [123211]. (b) The article also mentions that this breach at Broward Health is just one of numerous cyber incidents that have affected the health sector during the pandemic. It highlights that cybercriminals have been actively targeting hospitals and trying to profit from stolen data. Additionally, the article references a ransomware attack on the Los Angeles chapter of Planned Parenthood, compromising the personal information of about 400,000 patients. This indicates that similar incidents have occurred at multiple organizations within the health sector [123211].
Phase (Design/Operation) design (a) The software failure incident in Article 123211 was primarily due to a breach in the computer networks of Broward Health, a health care system in southeast Florida. The breach occurred through a "third-party medical provider," highlighting the exposure that hospitals and organizations have to hackers via their supply chains. This breach led to the exposure of sensitive personal and financial information of over 1.3 million people, including Social Security numbers, patient medical history, and bank account information [123211]. This incident can be attributed to contributing factors introduced during system development or updates that allowed hackers to access the network. (b) The operation of the system did not seem to be a direct contributing factor to the software failure incident in this case. The breach was primarily a result of hackers gaining unauthorized access to Broward Health's computer networks through a third-party medical provider, rather than being caused by the operation or misuse of the system itself [123211].
Boundary (Internal/External) within_system, outside_system (a) The software failure incident at Broward Health was due to contributing factors that originated from within the system. The breach occurred as hackers accessed Broward Health's computer networks via a "third-party medical provider," highlighting the exposure that hospitals and organizations have to hackers through their supply chains [Article 123211].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in the article is attributed to non-human actions, specifically hackers breaching the computer networks of a southeast Florida health care system. The breach resulted in the exposure of sensitive personal and financial information of over 1.3 million people, including Social Security numbers, patient medical history, and bank account information. The breach did not involve ransomware, and the hackers did not make any ransom demand. The intruders accessed the health care system's computer networks via a "third-party medical provider," highlighting the exposure that organizations have to hackers through their supply chains [Article 123211]. (b) The software failure incident in the article is not attributed to human actions but rather to the actions of cybercriminals who breached the health care system's computer networks. The breach was not a result of any actions taken by the health care provider or its employees. The incident did not involve any ransom demand or payment, indicating that the failure was not due to any human-initiated ransomware attack. The breach notice mentioned that the personal information was exfiltrated from the system, but there was no evidence that the information was misused by the intruder, further emphasizing the non-human nature of the failure [Article 123211].
