What action is required if a user’s SIPRNet token is compromised?

When a user’s SIPRNet token is compromised, the correct action is to report to the Trusted Agent. This step is crucial because the Trusted Agent plays a central role in managing PKI credentials and ensuring the security of the communication network. Reporting the compromise allows for immediate action to be taken, such as revoking the compromised token and preventing any unauthorized access.

Trustworthy management of security incidents is essential to maintain the integrity of the SIPRNet system, and the Trusted Agent is a designated authority who has the capacity to address the situation appropriately. This includes conducting any necessary investigations and implementing any preventive measures to safeguard sensitive information in the future.

While other actions, such as replacing the token, notifying supervisors, or changing passwords, could be part of the overall response to a compromise, they do not directly address the critical need to engage the Trusted Agent for proper protocol and incident management. The Trusted Agent ensures that such incidents are handled in a systematic manner according to established security policies and procedures.
