The Biba model is a security model that addresses the integrity of data within a system. It is not concerned with security levels and confidentiality. The Biba model uses integrity levels to prevent data at any integrity level from flowing to a higher integrity level.

Q. What does the Brewer and Nash model protect against?

This model is commonly used by consulting and accounting firms.
