Impacts 1. The confidential personal data of 1.8 million Texans, including names, Social Security numbers, addresses, phone numbers, and dates of birth, was exposed and available to the public for almost three years [128430]. 2. The incident led to unauthorized disclosure of sensitive information due to a glitch in the programming code of the Texas Department of Insurance's web application managing workers' compensation information [128430]. 3. The department had to take the application offline, conduct a forensic investigation to determine the nature and scope of the incident, and offer 12 months of credit monitoring and identity protection services to affected individuals [128430]. 4. The incident highlighted ongoing data security issues, indicating that data leaks and breaches continue to be a significant problem despite increased awareness [128430].
Preventions 1. Regular security audits and code reviews could have potentially identified the glitch in the programming code that led to the unauthorized disclosure of personal data [128430]. 2. Implementing stricter access controls and encryption measures for sensitive data within the web application could have helped prevent the exposure of confidential information to the public [128430]. 3. Conducting thorough testing, including penetration testing, to identify vulnerabilities in the web application before it goes live could have potentially caught the glitch that caused the data leak [128430].
Fixes 1. Implementing thorough code reviews and testing procedures to catch glitches in the programming code before deployment [128430]. 2. Enhancing data security measures within the web application to prevent unauthorized access to sensitive information [128430]. 3. Conducting regular security audits and assessments to proactively identify and address vulnerabilities in the software system [128430]. 4. Providing prompt incident response and notification procedures to mitigate the impact of software failures and data breaches [128430].

Software Taxonomy of Faults

Category Option Rationale
Recurring multiple_organization (a) The article does not provide information about a similar incident happening again within the same organization (TDI) or with its products and services. Therefore, it is unknown if a similar software failure incident has occurred again at TDI. (b) The article mentions that incidents like data leaks and breaches are a problem that doesn't seem to be getting better, with data breaches setting a record high last year and already up 14% in the first quarter of this year compared to last year's levels. This indicates that similar incidents have happened at multiple organizations, affecting millions of people [128430].
Phase (Design/Operation) design (a) The software failure incident in Article 128430 was due to a glitch in the programming code of the Texas Department of Insurance's web application that manages workers' compensation information. This glitch in the design phase of the system development led to the unauthorized disclosure of confidential personal data of 1.8 million Texans [128430].
Boundary (Internal/External) within_system (a) The software failure incident in Article 128430 was within_system. The incident was caused by a glitch in the programming code of the Texas Department of Insurance's web application that manages workers' compensation information [128430]. The unauthorized disclosure of personal data of 1.8 million Texans was a result of this internal system failure.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident occurred due to a glitch in the programming code of the Texas Department of Insurance's web application managing workers' compensation information, as reported in Article 128430. This glitch led to the unauthorized disclosure of personal data of 1.8 million Texans. The incident was attributed to a non-human factor, specifically a programming code glitch. (b) Human actions were involved in responding to the incident. The Texas Department of Insurance became aware of the problem, took the application offline, and initiated a forensic investigation to determine the nature and scope of the incident. They also worked on fixing the issue and providing credit monitoring and identity protection services to affected individuals. These actions were taken by humans in response to the software failure incident [128430].
Dimension (Hardware/Software) software (a) The software failure incident occurred due to a glitch in the programming code of the Texas Department of Insurance's web application, which led to the unauthorized disclosure of personal data of 1.8 million Texans [128430]. This glitch in the software code was the contributing factor that originated in the software itself, leading to the exposure of sensitive information. (b) The software failure incident was specifically attributed to a glitch in the programming code of the department's web application, indicating that the failure originated in the software [128430].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident in Article 128430 was non-malicious. The incident was attributed to a glitch in the programming code of the Texas Department of Insurance's web application that managed workers' compensation information. The unauthorized disclosure of personal data of 1.8 million Texans was not intentional but rather a result of a technical flaw in the system [128430].
Intent (Poor/Accidental Decisions) poor_decisions (a) The software failure incident related to the exposure of confidential personal data of 1.8 million Texans was primarily due to poor decisions. The incident was caused by a glitch in the programming code of the Texas Department of Insurance's web application managing workers' compensation information [128430]. This glitch led to the unauthorized disclosure of sensitive information, indicating that the failure was a result of contributing factors introduced by poor decisions in the development and maintenance of the software system.
Capability (Incompetence/Accidental) development_incompetence (a) The software failure incident in Article 128430 occurred due to development incompetence. The incident was caused by a glitch in the programming code of the Texas Department of Insurance's web application managing workers' compensation information. This glitch led to the exposure of confidential personal data of 1.8 million Texans for almost three years [128430].
Duration temporary (a) The software failure incident in Article 128430 was temporary. The incident involved a glitch in the programming code of the Texas Department of Insurance's web application that managed workers' compensation information. The glitch led to the exposure of confidential personal data of 1.8 million Texans for almost three years, from March 2019 until January 2022. The department became aware of the problem on Jan. 4, took the application offline, and fixed the issue. They also conducted a forensic investigation to determine the nature and scope of the incident and whether any information was accessed by unauthorized parties. The incident was not permanent as it was eventually identified, addressed, and steps were taken to mitigate the impact on affected individuals [128430].
