Security models provide a theoretical way of describing the security controls implemented within a system. In this video, learn about the Bell-LaPadula security model and the Biba Integrity Model, and their component rules. Also learn how these models work together to provide multilevel security for complex environments.
- [Narrator] Security models provide…a theoretical way of describing…the security controls implemented within a system.…We'll take a look at three core topics in this area:…the Bell-LaPadula security model, the Biba integrity model,…and the concept of multilevel security.…Both the Bell-LaPadula and Biba models…are designed to provide security…within the context of multilevel systems.…Multilevel security simply means…that a single computing system…might be used to store, process, and transmit information…of different classification levels…and the users of the system might have…different security clearances.…
For example, a system might handle…confidential, secret, and top secret information…even though some users of the system…don't have a top secret security clearance.…The Bell-LaPadula Model is designed…to insure that users of multilevel systems…don't get access to information higher…than their security clearance level.…It enforces confidentiality.…And it has two rules.…First, the simple security rule…is the basic principle of confidentiality.…
