Master the 2026 DoD Info Security & Insider Threat Test – Defend, Secure, Succeed!

The principle of Need to Know is essential in determining your role and responsibilities regarding sensitive information. This principle stipulates that individuals should only have access to information that is necessary for them to perform their official duties. It helps to minimize the risk of unauthorized access to sensitive information and protects national security by ensuring that only those individuals with a legitimate requirement to know can access such information.

By adhering to the Need to Know principle, organizations can effectively manage sensitive data and mitigate potential insider threats. This principle emphasizes the importance of safeguarding classified and sensitive materials and reinforces the idea that access is privilege-based rather than a universal right within an organization. The focus remains on protecting vital information while still allowing those with legitimate needs the access required to perform their jobs effectively.
