What is the focus of the Defense Information System for Security (DISS)?

The focus of the Defense Information System for Security (DISS) is specifically on personnel security actions and determinations. DISS provides a centralized platform for managing and recording the security clearance information of individuals within the Department of Defense, which is crucial for ensuring that only eligible personnel have access to certain sensitive information and facilities. It facilitates processes such as background investigations, adjudications, and the maintenance of security clearances, thus playing an essential role in safeguarding national security.

While options related to financial reporting, employee training, and criminal investigations are important in various contexts, they do not directly align with the primary purpose of DISS. The system is designed explicitly to enhance personnel security management, reflecting its commitment to maintaining a secure environment within the defense sector. This singular focus on personnel security ensures that DISS effectively supports the Department of Defense's objectives related to insider threat mitigation by monitoring the security status of personnel.
