What is one of the first tasks needed to evaluate whether software is considered 'trusted'?

One of the first tasks needed to evaluate whether software is considered 'trusted' is checking its alignment with TCSEC criteria. The Trusted Computer System Evaluation Criteria (TCSEC), also known as the Orange Book, provides a framework for assessing the security of computer systems and software. This evaluation focuses on how well the software can maintain confidentiality, integrity, and availability of information, which are fundamental aspects of a trusted system.

By aligning with the TCSEC criteria, evaluators can determine whether the software has been designed and implemented with necessary security features, such as access controls, auditing capabilities, and accountability measures. This systematic approach helps identify any potential vulnerabilities and ensures that the software meets required security standards before it is deployed in a sensitive environment.

In contrast, other options such as establishing user preferences, determining performance speed, or evaluating customer satisfaction, while important in their own contexts, do not directly address the security and trustworthiness of the software. Hence, they are not primary tasks in the evaluation of software as 'trusted.'
