Which of the following is an appropriate use of a DoD Public Key Infrastructure (PKI) token?

Using a PKI token only while actively engaged in a PKI-required task is appropriate because it minimizes the risk of unauthorized access and potential misuse of the token. PKI tokens are designed to authenticate and secure communications, and leaving them connected to a system when not in use can expose them to vulnerabilities, such as theft or exploitation. By ensuring that tokens are only utilized for designated tasks, users contribute to a more secure environment, aligning with best practices for cybersecurity within the Department of Defense. This approach emphasizes the importance of vigilance and careful management of sensitive security tools in the digital landscape.
