Since publication, the Bell-LaPadula model has helped in the advancement of science and technology by providing a mathematical basis for the examination of laboratory security. Moreover, this model is a major component of having a disciplined approach to building secure and effective laboratory systems.
The Bell-LaPadula model can also be used to abstractly describe the computer security system in the laboratory, without regard to the system's application. The goal of modern security research is to facilitate the construction of multilevel secure systems, which can protect information of differing classification from users that have varying levels of clearance.
There are some deficiencies inherent in the Bell and LaPadula model, and there have been efforts to develop a new approach to defining laboratory security models, on the basis that security models should be derived from specific applications.
The use of the Bell and LaPadula Model has been successful in modeling information that is relevant to security, even though this success might be responsible for the vagueness of the model. This vagueness can also be examined with the theory that the Bell and LaPadula Model and Noninterference are equivalent. Laboratory automation makes it possible for scientists to explore data rates that otherwise may be too fast or too slow to examine. ...Show more
