Description:
When you are building an application you first want to map where you are placing source files, libraries and executables.
With these components identified and mapped, it becomes transparent where possible pitfalls might be in your application and increases the maintainability of the system. Also you have an indicator where possible reinforcements have to be implemented to avoid attacks.(i.e places where your application contains executable's)
Solution:
Verify that all application components (either individual or groups of source files, libraries, and/or executables) that are present in the application are identified.
When you identified these components you may want to map and document them in order to have a quick reference to this infrastructure when needed.
