DISS stands for?

DISS stands for?

• A. Defense Information System for Security
• B. Defense Information System for Surveillance
• C. Defense Information Security System
• D. Department Information System for Security

Answer: (A)

The key idea here is identifying the official name of a DoD system used for handling personnel security information. DISS stands for Defense Information System for Security. It’s the DoD system that automates and centralizes background investigations, clearance statuses, and related security data for personnel, helping security professionals manage who has access to classified information. The other options mix different terms (surveillance, information security in a generic sense, or using a department rather than defense) and don’t reflect the specific DoD system used for security clearances. So the correct expansion is Defense Information System for Security.
