Recurring multiple_organization (a) The software failure incident related to the leaked HDCP master key is not explicitly mentioned to have happened again within the same organization (Intel) or with its products and services in the provided article [2862]. (b) The article mentions a previous incident related to a similar software failure involving a hacker posting a master key to "unlock" encrypted HD-DVDs on the social news website Digg.com in 2007. This incident was related to digital rights management (DRM) and the cracking of encryption keys, similar to the HDCP master key leak discussed in the article [2862]. Additionally, the article mentions that Computerworld technology writer Richi Jennings highlighted the latest master key leak as "an interesting academic exercise" and questioned the effectiveness of DRM, indicating a broader concern beyond just Intel's HDCP technology [2862].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the leak of the HDCP master key used for High Definition Content Protection. The incident was attributed to someone who had access to the keys during the development process or testing of HDCP-based devices or chips [2862]. (b) The software failure incident related to the operation phase can be inferred from the potential misuse of the leaked master key to create "black boxes" that allow unauthorized copying of movies. This misuse could occur due to the operation of implementing the leaked key in silicon, which was described as a difficult and costly process [2862].
Boundary (Internal/External) within_system (a) within_system: The software failure incident related to the leaked HDCP master key can be categorized as within_system. The incident occurred due to a leak of the 376-line HDCP antipiracy key that was originally released by Intel in 2004 [2862]. This leak originated from within the system, indicating a failure in maintaining the security and confidentiality of the key within the authorized group that had access to it during the development process or testing of HDCP-based devices [2862].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident related to non-human actions in this case is the leaking of the HDCP master key, which is a critical component of the High-bandwidth Digital Content Protection protocol. The leaked master key was posted anonymously on the internet, leading to concerns about potential unauthorized copying of copyright-protected HD media [2862]. (b) The software failure incident related to human actions involves the potential involvement of individuals who had access to the keys during the development process or were involved in testing HDCP-based devices or the chips that utilize HDCP technology. This suggests that the leak of the master key may have been facilitated by individuals with insider knowledge or access to the technology, highlighting the role of human actions in the incident [2862].
Dimension (Hardware/Software) hardware, software (a) The software failure incident related to hardware: - The leaked HDCP master key incident involves a hardware-related failure as the master key is used to stop unauthorized devices from playing copyright-protected HD media [2862]. - The leak of the HDCP master key could lead to the creation of "black boxes" that allow people to make unauthorized copies of movies, which involves hardware manipulation [2862]. (b) The software failure incident related to software: - The software failure incident in this case is primarily related to software as the HDCP (High Definition Content Protection) antipiracy key was leaked, which is a software-based protection mechanism [2862]. - The leak of the HDCP master key is a software-related issue as it involves the compromise of a software-based protection system designed to prevent unauthorized access to digital content [2862].
Objective (Malicious/Non-malicious) malicious (a) The software failure incident related to the leaked HDCP master key can be categorized as malicious. The incident involved the unauthorized release of the master key used to stop unauthorized devices from playing copyright-protected HD media. The leak of this key could potentially lead to the creation of "black boxes" that allow people to make unauthorized copies of movies, indicating a malicious intent to circumvent copyright protection measures [2862].
Intent (Poor/Accidental Decisions) poor_decisions, accidental_decisions The software failure incident related to the leaked HDCP master key can be attributed to both poor decisions and accidental decisions: (a) poor_decisions: The incident can be linked to poor decisions as the leak of the HDCP master key was a result of someone having access to the keys during the development process or testing HDCP-based devices, indicating a lapse in security protocols or access control [2862]. (b) accidental_decisions: On the other hand, the leak could also be seen as an accidental decision or unintended consequence, as it may not have been the original intent of those involved in the development or testing of HDCP-based devices to have the master key leaked [2862].
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident related to development incompetence can be seen in the leaked HDCP master key incident reported in Article 2862. The incident involved a significant security breach where the master key used to stop unauthorized devices from playing copyright-protected HD media was anonymously posted on the internet. This breach was attributed to someone who either had access to the keys during the development process or someone involved in testing HDCP-based devices or the chips that go into them [2862]. (b) The software failure incident related to accidental factors can be observed in the same leaked HDCP master key incident. The leak of the master key was not intentional but rather accidental, leading to potential misuse by individuals to create "black boxes" for making unauthorized copies of movies. The accidental release of the key raised concerns about the security of HDCP technology and its effectiveness in protecting digital content [2862].
Duration permanent (a) The software failure incident related to the leaked HDCP master key can be considered permanent. The incident involved the release of a 376-line HDCP anti-piracy key by Intel in 2004, which was confirmed to be authentic. This key could potentially be used to create "black boxes" allowing unauthorized copying of movies. Despite the leak, Intel believed that the technology would remain effective due to legal remedies under the DMCA (Digital Millennium Copyright Act) and the difficulty and cost associated with implementing the keys in silicon. Additionally, experts suggested that the leak would implicate HDCP further and render it ineffective as a security measure, essentially making it a "dead letter" in terms of security [2862].
Behaviour other (a) crash: The incident described in the article does not involve a crash where the system loses state and does not perform any of its intended functions. The software failure incident in this case is related to the leak of the HDCP master key used for copyright protection of HD media [2862]. (b) omission: The software failure incident is not related to the system omitting to perform its intended functions at an instance(s). Instead, the failure is due to the unauthorized release of the HDCP master key, potentially leading to the creation of "black boxes" for making unauthorized copies of movies [2862]. (c) timing: The software failure incident is not related to the system performing its intended functions correctly but too late or too early. The focus of the incident is on the leak of the HDCP master key and the implications it may have on content protection [2862]. (d) value: The software failure incident is not related to the system performing its intended functions incorrectly. The issue here is the unauthorized disclosure of the HDCP master key, which could potentially be used to circumvent content protection measures [2862]. (e) byzantine: The software failure incident does not involve the system behaving erroneously with inconsistent responses and interactions. The primary concern is the security implications of the leaked HDCP master key and the potential for unauthorized copying of protected content [2862]. (f) other: The behavior of the software failure incident in this case is related to a security breach resulting from the unauthorized release of the HDCP master key, which could compromise the protection of copyrighted HD media [2862].
