It protects confidentiality by enforcing no read down and no write up.
The Bell-LaPadula model was created for military multilevel security systems to protect confidentiality. It enforces a no read-up, no write-down policy so that subjects cannot read data at a higher classification level or write data to a lower classification level, preventing unauthorized disclosure. The Biba model, by contrast, protects integrity with no read-down, no write-up rules.
