What type of incidents must be reported within DISS?

The correct response focuses on the requirement to report specific incidents that threaten the integrity and security of information related to defense and national security. The essential principle guiding the reporting process is to ensure that any security breaches, unauthorized disclosures, or compromises of classified information are documented and addressed promptly. This includes situations where sensitive or classified information could fall into the wrong hands, which poses a risk not just to individuals but to broader national security.

Reporting these types of incidents is crucial because it helps organizations mitigate risks, improve security procedures, and take corrective actions to prevent future occurrences. By systematically documenting and analyzing these breaches, agencies can continuously refine their security protocols and ensure compliance with regulatory and policy requirements. Thus, focusing specifically on breaches related to classified information allows for a heightened level of security vigilance in handling sensitive information.
