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

The Enhanced Trusted Agent (ETA) system requirements include a comprehensive approach to maintaining the security and integrity of the PKI system. This involves several critical components that are essential for its safe and effective operation.

Monitoring internet access is vital as it helps to detect any unauthorized attempts to access or manipulate the PKI system, ensuring that data transmission is secure and compliant with policies. Regular training of personnel is also fundamental because having knowledgeable staff is key to maintaining a secure environment; ongoing education ensures that team members are aware of the latest security practices and threats. Improvement of data encryption is necessary to protect sensitive information against breaches and unauthorized access, as strong encryption is a primary defense mechanism for data security.

By recognizing that all these components are integral parts of the ETA system requirements, it becomes clear why the answer encompasses the collective aspects of monitoring, training, and encryption improvements, affirming that a holistic approach is required for effective system management and security within the PKI framework.
