What does the DISS system primarily aim to protect?

The DISS system, or Defense Information System for Security, primarily aims to protect sensitive information and security clearances. This system is vital for ensuring that individuals who require access to classified or sensitive data are properly vetted and that their information is kept secure. By focusing on the protection of sensitive information, DISS helps maintain national security and integrity within defense-related operations.

While options related to public relations strategy, financial investment strategies, and corporate branding may involve various aspects of organizational operation and communication, they do not pertain directly to the DISS system's core purpose of safeguarding security clearances and sensitive data. This delineation underscores the specific focus on national security and the protection of classified information within the context of the DISS framework.
