What is the Biba Model?
The Biba Model is a formal security model designed to ensure data integrity by preventing unauthorized or improper modification of data. It operates on principles opposite to the Bell-LaPadula Model, which focuses on confidentiality.
The Biba Model enforces rules such as “no write up” and “no read down,” ensuring that data flows in a way that maintains integrity across systems.
What is the Biba Model used for?
The Biba Model is used in environments where data integrity is critical, such as financial systems and industrial control systems. It helps prevent corruption of sensitive data and ensures trustworthiness.
Security architects may apply Biba principles within Access Control and system design to maintain data integrity alongside other principles such as the CIA Triad.
