Which of the following is a potential consequence of mishandling classified information?

Mishandling classified information can lead to significant harm to national security interests. When classified information is improperly accessed, disclosed, or stored, it can allow unauthorized individuals to gain insights into sensitive operations, plans, or capabilities. This might result in adversaries being better positioned to exploit vulnerabilities, launch attacks, or undermine strategic initiatives. Such occurrences could jeopardize not only ongoing operations but also broader national security objectives and alliances.

The other options, while they might be outcomes in different contexts, do not represent the inherent risks associated with mishandling classified information. For instance, if mishandling occurs, it is unlikely to lead to positive publicity for the organization, as such incidents typically lead to reputational damage and loss of trust. Similarly, while security protocols may need improvement following a mishandling incident, it is not a direct consequence of the wrongdoing itself. The discovery of new security gaps can occur, but this is more of an evaluation outcome rather than an immediate consequence of mishandling classified information. Thus, the most direct and serious consequence linked with mishandling classified information is the potential harm it causes to national security interests.
