What level of security must III data obtained from terminal devices have?

The correct answer is based on the requirement that III (Interstate Identification Index) data obtained from terminal devices must be afforded a specific level of protection to ensure its confidentiality, integrity, and availability. This means that the data, which includes sensitive personal information, must be safeguarded against unauthorized access or disclosure.

Affording security involves implementing measures that comply with established standards and policies for data protection, particularly for criminal justice information. These measures typically include secure access controls, encryption, and regular audits. The importance of this level of security stems from the need to protect individuals' privacy rights and maintain the integrity of the justice system.

Other options suggest varying degrees of security that do not adequately reflect the necessary protection level for sensitive criminal justice data like that in the III system. Each of those alternatives implies a lower standard of protection, which could potentially lead to unauthorized access or misuse of the information. Therefore, understanding that III data requires a high level of security reflects the commitment to safeguarding sensitive data in law enforcement and criminal justice contexts.
