Multilevel Secure Rules and Its Impact on the Design of Active Database Systems

The event-condition-action paradigm (also known as triggers or rules) gives a database “active” capabilities – the ability to react automatically to changes in the database or in the environment. One potential use of this technology is in the area of multilevel secure (MLS) data processing, such as, military, where the subjects and objects are classified into different security levels and mandatory access control rules govern who has access to what. Unfortunately, not much work has been done in the area of multilevel secure active database system. In this paper we define the structure of MLS rules and identify what effects these rules have on the execution semantics of an active database system. Such knowledge is essential before developing a multilevel secure active database system.
