How to secure Business Objects

This post explains how you can secure your business objects in a model driven way, using the Imixs-Workflow engine.

Most applications deal with security in a functional way. This means that a business application typically defines different functional roles which are mapped to different users. For example let’s look on a simple Ordering System. In an Ordering System, we will have roles like

  • Order-Creator‘ – creating the order
  • Order-Approver‘ – validating and approving
  • Order-Executor‘ – execution

These roles are typical for such an business application and mostly tightly coupled to the corresponding business methods – e.g. createOrder(), approveOrder() and executeOrder(). This works well in a monolithic business application where you can control the security layers as also the business logic. But as more complex the business application becomes, also the enclosed security becomes more complicated. For modern application design, in addition, you often have to deal with external web services and business logic which need to be adapted easily to changing requirements. So this static security model leads into a hell of hard coded business rules or, what is worse, can no longer guarantee the security. read more »
