Software Taxonomy of Faults

Category Option Rationale
Recurring multiple_organization (a) The software failure incident having happened again at one_organization: The article does not mention any previous incidents of a similar nature happening at Anthem Inc. It primarily focuses on the data breach incident that occurred at Anthem Inc. [33638]. (b) The software failure incident having happened again at multiple_organization: The article mentions that the FBI had warned in August about healthcare industry companies being targeted by hackers, citing a previous attack on U.S. hospital group Community Health Systems Inc that resulted in the theft of millions of patient records. This indicates that similar incidents have occurred at multiple organizations within the healthcare industry [33638].
Phase (Design/Operation) design, operation (a) The software failure incident in Article 33638 was primarily due to a breach in one of Anthem Inc's IT systems, indicating a failure related to the design phase. The breach allowed hackers to steal personal information of millions of customers and employees, highlighting a vulnerability in the system's design that enabled unauthorized access to sensitive data [33638]. (b) Additionally, the incident could also be attributed to factors related to the operation phase. The breach was a result of a "very sophisticated attack," indicating that the system's operation and security measures may have been inadequate to prevent such intrusions. The misuse of the system by hackers exploiting vulnerabilities points to operational weaknesses that allowed the breach to occur [33638].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident reported in the article about Anthem Inc. being hacked and personal information being stolen was primarily due to a vulnerability within the company's IT system. Anthem mentioned that the breach involved hackers accessing one of its IT systems and stealing personal information of customers and employees. The company immediately made efforts to close the security vulnerability within its system [33638]. (b) outside_system: The software failure incident was also influenced by factors originating from outside the system. The article highlighted that cybersecurity firm FireEye Inc. was hired to help Anthem investigate the attack, indicating the involvement of external expertise to address the breach. Additionally, the FBI was informed about the attack, suggesting external involvement in handling the aftermath of the incident [33638].
Nature (Human/Non-human) human_actions (a) The software failure incident in this case was not due to non-human actions but rather a sophisticated cyberattack by hackers. The breach involved hackers breaching Anthem Inc's IT systems and stealing personal information of millions of customers and employees [33638]. (b) The failure was primarily due to human actions, specifically the actions of the hackers who conducted the cyberattack on Anthem Inc's IT systems. The breach was described as a "very sophisticated attack" that resulted in the theft of personal information such as names, birthdays, social security numbers, and more [33638].
Dimension (Hardware/Software) software (a) The software failure incident reported in Article 33638 was not due to hardware issues but rather a sophisticated cyber attack by hackers who breached Anthem Inc's IT systems and stole personal information of millions of customers and employees. The breach did not involve medical information or financial details like credit card numbers, indicating that the failure originated from external factors (hackers) rather than internal hardware issues [33638]. (b) The software failure incident in Article 33638 was primarily due to contributing factors originating in software, as hackers exploited a security vulnerability in Anthem Inc's IT systems to gain unauthorized access to sensitive personal information.
