Explanation
The Biba model is a data integrity model that assumes a lattice of integrity levels, where each subject and object has a fixed integrity level. The model enforces two rules: the simple integrity property and the *-integrity property. The simple integrity property states that a subject can only read an object with an equal or lower integrity level. The *-integrity property states that a subject can only write to an object with an equal or higher integrity level. These rules prevent data corruption from low- integrity sources and unauthorized modification from high-integrity sources.
