What are the Advantages and disadvantages of biba security model?

Answer 1

The Biba security model is designed to maintain data integrity by preventing unauthorized users from modifying data. Its primary advantages include ensuring that lower-level users cannot alter data at higher security levels, thereby protecting sensitive information from corruption. However, a significant disadvantage is that it can limit data availability and accessibility, as users may be restricted from accessing or modifying necessary information due to their security level. Additionally, the model may not adequately address confidentiality, as it prioritizes integrity over other security principles.
