The Bell-LaPadula security model focuses primarily on protecting the integrity of data rather than confidentiality.
True
False
The Bell-LaPadula security model is designed primarily to protect confidentiality of data, not integrity. This model was developed for military applications and implements a formal policy for controlling access to classified information. It enforces the "no read up, no write down" principle where subjects cannot read objects at higher security levels (no read up) and cannot write to objects at lower security levels (no write down).
In contrast, the Biba security model focuses on protecting data integrity through its "no read down, no write up" principle.
Remembering these distinctions between security models is crucial for the CISSP exam, as they represent different approaches to securing information systems based on different security priorities.
