Biba

Biba is a term with multiple meanings across technology, fashion, and onomastics. In computer security, it denotes the Biba integrity model, a formal framework for preserving data integrity. In Indian fashion, Biba is a well-known label that specializes in women’s wear. The name is also used as a personal name in various cultures and languages.

Biba integrity model: Proposed by Kenneth J. Biba in 1977, the model enforces data integrity by restricting how information can flow between levels of integrity. It uses a lattice of integrity levels and defines two main properties: the simple integrity property (no read down) and the integrity star property (no write up). Together, these rules prevent higher-integrity subjects from being contaminated by lower-integrity data and prevent lower-integrity data from corrupting higher-integrity data. The Biba model is often discussed in relation to the Bell-LaPadula model, which emphasizes confidentiality rather than integrity.
