Modularization of Enterprise Application Security Through Spring AOP

The goal of the paper is to present that Aspect Oriented Programming AspectJ integrated with Spring AOP provides very powerful mechanisms for modularizing enterprise security cross-cutting concerns. Aspect-oriented programming (AOP) allows weaving a security aspect into an application providing additional security functionality or introducing completely new security mechanisms.Spring’s proxy-based AOP framework is well suited for handling many generic middleware and application-specific problems. The most important part of the Spring/AspectJ integration allows Spring to configure AspectJ aspects using Dependency Injection. This brings similar benefits to aspects as to objects. Also Spring has ability to provide AspectJ pointcut expressions to be used in Spring XML or other bean definition files, to target Spring advice. This will allow some of the power of the AspectJ pointcut model to be applied to Spring’s proxy-based AOP framework. Implementation of security with AOP is a flexible method to develop separated, extensible and reusable pieces of code called aspects. In this inquisitive study, we bring some insight about the usage of powerful technology for developing secure enterprise applications.
