What must be filed if classified information is compromised?

When classified information is compromised, it is essential to file an incident report through the appropriate channels. This step is crucial for several reasons. First and foremost, reporting the incident ensures that the organization can assess the nature and scope of the compromise, which is critical for determining the appropriate response and mitigating any potential damage.

Filing an incident report allows for an investigation to be initiated, wherein security personnel can evaluate how the breach occurred, identify the vulnerabilities that were exploited, and develop strategies to prevent future occurrences. Furthermore, this process contributes to accountability and transparency within the organization, as it creates a formal record of what happened and enables appropriate stakeholders to review and address the situation.

In contrast, while other options might seem relevant to enhancing security or compliance, they do not specifically address the immediate need for documentation and reporting that comes with a compromise of classified information. An incident report is a fundamental requirement in the context of information security, aligning with the protocols set forth by the Department of Defense for handling classified information breaches.
