Which directive requires the appointment of disclosure authorities for classified information?

The correct answer is Department of Defense Directive 5230.11, which specifically requires the appointment of disclosure authorities responsible for classified information. This directive outlines the framework for the disclosure of classified information to foreign governments and international organizations. By establishing a designated disclosure authority, the directive ensures that there is accountability and oversight in the handling of sensitive information, promoting compliance with U.S. laws and policies related to national security.

This directive plays a pivotal role in facilitating controlled and authorized exchanges of data, thereby safeguarding national interests while fostering alliances and partnerships with international entities. Ensuring that only appointed officials can make disclosure decisions helps to mitigate risks associated with unauthorized access to classified data.

Other directives mentioned might relate to various aspects of information security or foreign military sales, but they do not specifically mandate the appointment of disclosure authorities for classified information, which is a core aspect of Directive 5230.11.
