An application security has two primary goals: first, it is intended to prevent unauthorized personnel from accessing information at higher classification than their authorization. Second, it is intended to prevent personnel from declassifying information. Using an object oriented approach to implementing application security results not only with the problem of code scattering and code tangling, but also results in weaker enforcement of security. This weaker enforcement of security could be due to the inherent design of the system or due to a programming error. Aspect Oriented Programming (AOP) complements Object-Oriented Programming (OOP) by providing another way of thinking about program structure. The key unit of modularity in OOP is the class, whereas in AOP the unit of modularity is the aspect.
