摘要：Many specialists believe that more emphasis on system infrastructure is needed, including the protection of the system¡¯s data against unauthorized use or updates. This paper proposes a way to teach future information system specialists the main concepts involved, using a powerful yet very flexible method to implement access control. Constraints, widely known as context constraints, which depend on the value of a variable or data item, are included. We discovered it was extremely difficult for students to understand, let alone adopt, a model as general as the one we use to explain the necessary ingredients of an Access Control model. However, the order in which the concepts were introduced produced a very significant increase in the degree of understanding on the part of the students. Rather than just provide another method, the paper¡¯s objective is to promote discussion as well as further study of the subject.
