text: **3.7.2 Layers**
  
  Figure 3-10 shows the application layer at the top layer of the architecture. Those applications 
  rely on the Data Security Integration Services layer, which gives the capability to connect with 
  the security data sources. The environment is based on the Application Framework layer that 
  allows the integration of several components, including composable (BYOA) applications to 
  create applications and integrate them in the framework.
