Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident related to the data leak of private account information from the New York bicycle-sharing program Citi Bike was a unique incident for the organization. There is no mention in the article of a similar incident happening before within the same organization or with its products and services. (b) There is no information in the article about a similar incident happening before at other organizations or with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase was due to a software glitch that caused the New York bicycle-sharing program Citi Bike to accidentally leak the private account information of 1,174 customers. This glitch exposed sensitive data such as names, contact information, credit card numbers, security codes, passwords, and birth dates [20549]. (b) The software failure incident related to the operation phase was seen in the delayed notification to the affected customers. The breach occurred on April 15, but the customers were not informed until July 19. This delay in notifying the affected individuals could be considered a failure in the operation or communication process of handling the security incident [20549].
Boundary (Internal/External) within_system (a) The software failure incident related to the Citi Bike data leak was within the system. The incident was caused by a software glitch within the Citi Bike system that led to the exposure of private account information of 1,174 customers [20549]. The breach was discovered internally by Citi Bike at the end of May, and the company took immediate corrective actions to address the issue [20549].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in the Citi Bike data leak was due to a non-human action, specifically a software glitch that exposed the private account information of 1,174 customers [20549]. The breach occurred just before the program launched, and the company discovered and corrected the glitch at the end of May. The data leak included sensitive information such as names, contact details, credit card numbers, security codes, passwords, and birth dates. The breach was not attributed to any malicious access or misuse of the information [20549]. (b) Human actions were involved in the response to the software failure incident. After discovering the breach, Citi Bike engaged a security firm to investigate and recommend appropriate steps to notify and safeguard its customers. The company also provided identity and credit monitoring free of charge to the affected customers. Additionally, IDentity Theft 911 advised customers to take steps such as changing passwords for other websites if they used the same password, watching out for scams, and placing a fraud alert on their credit file [20549].
Dimension (Hardware/Software) software (a) The software failure incident related to hardware: The incident of private account information leakage in the New York bicycle-sharing program Citi Bike was attributed to a software glitch, indicating that the failure originated in the software system rather than the hardware components [20549]. (b) The software failure incident related to software: The same incident of private account information leakage in Citi Bike was specifically mentioned to have occurred due to a software glitch, highlighting that the contributing factors of this failure originated within the software itself [20549].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident in the Citi Bike case was non-malicious. The incident was described as a data leak caused by a software glitch, which accidentally exposed the private account information of 1,174 customers [20549]. The New York City Department of Transportation spokesman mentioned that there was no evidence of any personal information being maliciously accessed or misused. Additionally, the company engaged a security firm to investigate the breach and recommend steps to safeguard its customers, including providing identity and credit monitoring free of charge [20549].
Intent (Poor/Accidental Decisions) accidental_decisions (a) The intent of the software failure incident was accidental_decisions. The incident was described as an accidental leak of private account information due to a software glitch just before the launch of the New York bicycle-sharing program Citi Bike [20549]. The leak included sensitive data such as customers' names, contact information, credit card numbers, security codes, passwords, and birth dates. The company discovered the breach at the end of May and immediately corrected it, but the affected customers were not notified until July 19. The incident was not attributed to poor decisions but rather to an unintended mistake or glitch in the software system.
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident related to development incompetence is evident in the article as it mentions that the private account information of 1,174 customers was accidentally leaked due to a software glitch just before the launch of the New York bicycle-sharing program Citi Bike [20549]. This indicates a lack of professional competence in ensuring the security and privacy of customer data during the development and testing phases of the software. (b) The software failure incident was also accidental, as the data leak was described as occurring accidentally through a software glitch, rather than as a deliberate act [20549]. The incident was not intentional but rather a result of unintended consequences of the software system.
Duration temporary The software failure incident related to the data leak in the New York bicycle-sharing program Citi Bike was temporary. The incident was caused by a software glitch that exposed the private account information of 1,174 customers [20549]. The breach was discovered at the end of May and corrected immediately, indicating that the failure was temporary and not a permanent issue.

The incident involved a software glitch that led to the exposure of private account information of 1,174 customers of the Citi Bike program [20549]. (b) omission: There is no specific mention of the software failure incident being related to omission in the articles. (c) timing: The incident does not seem to be related to timing issues where the system performed its intended functions too late or too early. (d) value: The software failure incident does not involve the system performing its intended functions incorrectly. (e) byzantine: The incident does not exhibit characteristics of a byzantine failure where the system behaves erroneously with inconsistent responses and interactions. (f) other: The behavior of the software failure incident in the article can be categorized as a data leak due to a software glitch, leading to the exposure of sensitive customer information.
