Which of the following is included in the Enhanced Trusted Agent system requirements?

The Enhanced Trusted Agent system requirements encompass a comprehensive set of criteria that are essential for ensuring a robust and secure infrastructure. When considering the requirement for secure communications, it is critical as it protects the data exchanged within the system from interception or tampering. This ensures that all information transmitted remains confidential and secure.

Credential verification is another fundamental requirement that guarantees that each individual accessing the system is authorized to do so. This process is crucial for maintaining the integrity of the system and preventing unauthorized access, thereby safeguarding sensitive information and resources.

Reporting to upper management serves as a mechanism for oversight and accountability. It allows for monitoring the system's performance, ensuring adherence to policies, and facilitating strategic decision-making based on the operations and security posture of the organization.

Given that secure communications, credential verification, and reporting to management are all vital components that contribute to the effectiveness of the Enhanced Trusted Agent system, it is accurate to state that all of these elements must be included in the requirements. Therefore, the answer that encompasses all of these necessary aspects captures the full scope of what is needed to operate a trusted agent effectively.
