Bell-LaPadula Security Model
The Bell-LaPadula Security Model is a framework used mainly in government and military settings to protect sensitive information. It focuses on controlling who can access and share data based on their security clearance levels. The model enforces rules where users can only read data at or below their clearance (no "reading up") and can only write data at or above their clearance (no "writing down"). This ensures information flows securely, preventing unauthorized access or leakage of classified data while maintaining confidentiality.
