Which of the following is an appropriate response to unauthorized disclosure of classified information?

Conducting internal investigations is essential when faced with unauthorized disclosure of classified information. This response allows an organization to thoroughly examine the circumstances surrounding the disclosure, identify the source, and understand the extent of the breach. Internal investigations help in assessing the impact on national security, determining if any policies were violated, and taking necessary actions to prevent future incidents. It's a critical process for maintaining the integrity of classified information and ensuring compliance with regulations regarding its handling.

Other responses may not appropriately address the severity of the situation. Celebrating transparency trivializes the seriousness of unauthorized disclosures, while ignoring the incident can lead to further breaches and loss of trust. Reclassifying the data does not address the root cause of the problem and may only mask the issue without resolving it.
