In terms of safeguarding PSI, which statement reflects proper practice?

The statement that investigative reports must be protected based on their classification level accurately reflects proper practice in safeguarding Protected Sensitive Information (PSI). This principle is rooted in the necessity to maintain the confidentiality, integrity, and availability of sensitive information that could potentially harm national security or individual privacy if disclosed without authorization.

In practice, each level of classification—whether it be Confidential, Secret, or Top Secret—dictates the specific safeguarding measures that must be implemented. This includes physical security, access controls, and handling procedures tailored to the sensitivity of the information. Maintaining adherence to these classification criteria helps ensure that individuals who have access to such information are properly vetted and that the information itself is only accessible to those with a need to know.

Safeguarding PSI is essential in preventing unauthorized access and potential espionage, which could compromise national security or sensitive operations. Proper classification and protection of investigative reports serve as a critical defense mechanism within personnel security practices.
