Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident related to serious security vulnerabilities affecting Apple devices has happened before with Apple products. The article mentions that this isn't the first time Apple has released security update warnings for similar situations, as a very similar incident occurred in March of the same year [131040]. (b) The software failure incident related to serious security vulnerabilities affecting Apple devices has also happened with other organizations or their products. The article mentions that commercial spyware company NSO Group is known for locating and taking advantage of flaws in Apple's iOS and deploying malware to infect smartphones for data theft and surveillance [131040].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the article where serious security vulnerabilities were disclosed for iPhones, iPads, and Macs. The issues were found in WebKit, the browser engine that powers Safari, and in the Kernel, which is the core of the operating system [131040]. (b) The software failure incident related to the operation phase is evident in the article where users were urged to update their affected devices to mitigate the security vulnerabilities. The update, iOS 15.6.1, and MacOS Monterey 12.5.1 were released to address the issues found in WebKit and Kernel, which could potentially allow attackers to take complete control of the devices [131040].
Boundary (Internal/External) within_system (a) The software failure incident reported in the articles is primarily within the system. The security vulnerabilities affecting Apple devices, including iPhones, iPads, and Macs, were discovered within the system's components such as WebKit and Kernel. The vulnerabilities allowed attackers to potentially take complete control of the devices by executing arbitrary code with Kernel privileges [131040]. The update released by Apple, iOS 15.6.1, addressed these internal system vulnerabilities to enhance security and prevent unauthorized access to user devices.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident occurring due to non-human actions: The software failure incident in this case was due to serious security vulnerabilities found in Apple's software, specifically in WebKit and Kernel, which are non-human components of the system [131040]. (b) The software failure incident occurring due to human actions: The software failure incident was exacerbated by the fact that historically, many users had not updated their Apple products for fear of shortening the lifespan of their devices. This behavior of not updating devices promptly contributed to the vulnerability being exploited by potential attackers [131040].
Dimension (Hardware/Software) hardware (a) The software failure incident occurring due to hardware: - The software failure incident reported in the articles is related to serious security vulnerabilities for iPhones, iPads, and Macs that could potentially allow attackers to take complete control of the devices [131040]. - The vulnerabilities were found in the Kernel, which is the core of the operating system, and in WebKit, the browser engine that powers Safari [131040]. - The vulnerabilities were tracked as 'CVE-2022-32893' for WebKit and 'CVE-2022-32894' for the Kernel [131040]. (b) The software failure incident occurring due to software: - The software failure incident itself is not due to contributing factors originating in software but rather due to security vulnerabilities in the software that could be exploited by attackers [131040]. - The vulnerabilities were found in the software components like WebKit and Kernel, but the root cause of the failure is not attributed to issues in the software itself [131040].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident reported in Article 131040 is malicious in nature. Apple disclosed serious security vulnerabilities for iPhones, iPads, and Macs that could potentially allow attackers to take complete control of the devices. The vulnerabilities were found in WebKit and Kernel, allowing a malicious application to execute arbitrary code with Kernel privileges, providing full access to the device. Security experts emphasized the importance of updating affected devices to mitigate the risk of exploitation by hackers [131040].
Intent (Poor/Accidental Decisions) accidental_decisions The software failure incident reported in Article 131040 was due to accidental_decisions. The failure was caused by serious security vulnerabilities discovered in iPhones, iPads, and Macs that could potentially allow attackers to take complete control of the devices. Apple urged users to update their devices to address the vulnerabilities, which were found in WebKit and Kernel components of the operating system [131040].
Capability (Incompetence/Accidental) development_incompetence (a) The software failure incident occurring due to development incompetence: - The software failure incident in this case was due to serious security vulnerabilities found in Apple's iOS, iPadOS, and MacOS systems [131040]. - The vulnerabilities were discovered by an anonymous researcher in WebKit and Kernel, which are critical components of the operating system [131040]. - The vulnerabilities allowed attackers to potentially take complete control of affected devices, leading to concerns about unauthorized access to sensitive data and device functions [131040]. - Security experts emphasized the importance of updating affected devices to mitigate the risks posed by these vulnerabilities [131040]. - The incident highlighted the need for users to regularly update their devices to address security flaws and protect their personal information [131040]. (b) The software failure incident occurring accidentally: - The software failure incident was not described as occurring accidentally in the articles provided [131040]. - The vulnerabilities were identified by an anonymous researcher, suggesting a deliberate search for security weaknesses rather than accidental discovery [131040]. - The seriousness of the vulnerabilities and the potential impact on user data and device control indicate a deliberate exploitation risk rather than accidental introduction of flaws [131040]. - The incident prompted urgent action from Apple and security experts to address the vulnerabilities and protect users from potential exploitation [131040].
Duration temporary The software failure incident reported in the articles is temporary. The incident involves serious security vulnerabilities in Apple devices, specifically iPhones, iPads, and Macs, that could potentially allow attackers to take complete control of the devices. Apple released updates, iOS 15.6.1 and MacOS Monterey 12.5.1, to address the vulnerabilities found in WebKit and Kernel components of the operating system [131040]. The incident is temporary as it is caused by specific vulnerabilities that were discovered and patched by Apple through software updates.
Behaviour omission, value, other (a) crash: The software failure incident reported in the articles does not specifically mention a crash where the system loses state and does not perform any of its intended functions. (b) omission: The software failure incident is related to a serious security vulnerability in Apple devices, specifically iPhones, iPads, and Macs. The vulnerability could potentially allow attackers to take complete control of the devices by executing arbitrary code with Kernel privileges, gaining full access to the device. This omission to perform its intended functions securely led to the need for urgent software updates to address the vulnerabilities [131040]. (c) timing: The software failure incident does not relate to timing issues where the system performs its intended functions but too late or too early. (d) value: The software failure incident is related to the system performing its intended functions incorrectly due to serious security vulnerabilities that could allow attackers to take control of Apple devices. This incorrect behavior poses a significant risk to user data and device security [131040]. (e) byzantine: The software failure incident does not exhibit byzantine behavior where the system behaves erroneously with inconsistent responses and interactions. (f) other: The software failure incident involves a serious security flaw in Apple devices that could potentially allow attackers to take complete control of the devices. This behavior is categorized as a critical security vulnerability rather than fitting into the specific options provided [131040].
