Bell-LaPadula Model

The Bell-LaPadula Model is a security framework used to regulate access to sensitive information, primarily in government and military contexts. It operates on two key principles: "no read up" and "no write down." This means a person with lower security clearance cannot access information at a higher level (no read up), and they cannot share their information with someone at a lower clearance (no write down). This helps prevent unauthorized access and protects confidential data, ensuring that sensitive information remains secure from those who shouldn't see it.
