Which example constitutes unauthorized disclosure?

Leaving a classified document on a photocopier represents a situation of unauthorized disclosure because it exposes sensitive information to individuals who may not have the necessary clearance or need-to-know basis to access such information. When classified materials are not properly secured, or are left unattended in public or semi-public areas, it significantly increases the risk of inadvertent or intentional access by unauthorized individuals. In an environment where confidentiality and security of sensitive information are paramount, such a lapse in protocol directly violates the standards and practices set to protect classified data.

The other scenarios, in contrast, demonstrate proper handling and management of classified information. Consolidating classified information in a secure database and discussing classified topics with authorized personnel reflect adherence to internal safeguarding protocols. Similarly, securely filing documents at the end of the day indicates diligence in ensuring that all sensitive materials are properly stored away, mitigating the risk of unauthorized access.
