C. Safety, reliability, availability, resilience, and security Safety: Ensures that the software does not pose risks to people, property, or the environment during its operation. Reliability: Refers to the ability of the software to perform consistently and predictably over time without unexpected failures. Availability: Ensures that the software is accessible and operational when needed, minimizing downtime and disruptions in supply chain processes. Resilience: The software should be able to recover quickly from failures, errors, or disruptions, minimizing the impact on supply chain operations. Security: Protects the software and its data from unauthorized access, breaches, and cyber threats, ensuring the confidentiality, integrity, and authenticity of information.

The facets of trustworthy software in supply chain operations typically revolve around ensuring the security, integrity, and reliability of the software and its associated data. Therefore, option C, "Safety, reliability, availability, resilience, and security," aligns with these facets. In supply chain operations, it's crucial to have software that is safe to use, reliable in its performance, available when needed, resilient to failures, and secure to protect against threats and vulnerabilities. These facets collectively contribute to trustworthy software within the supply chain context.

This seems to be a question where you should choose the best answer, but where no answer is spot on. It seems like Functionality in A and Possession in B is not what we are looking for. Also Reparability and Upgradability are not really CISSP buzz words. Therefore I would go for C. In case Possion in answer B would be replaced with non-repudiation I would go for B..

C is correct

C. Safety, reliability, availability, resilience, and security are the facets of trustworthy software in supply chain operations. Trustworthy software in supply chain operations requires that the software possess key characteristics such as safety, reliability, availability, resilience, and security. Safety ensures that the software does not harm people or the environment. Reliability ensures that the software works as intended and does not fail prematurely. Availability ensures that the software is available when needed. Resilience ensures that the software can withstand and recover from disruptions. Security ensures that the software is protected from unauthorized access, modification, or destruction.
