Is There a Reverse Ability?

In the world of sculana core, i can very cleanly in my application code. I can focus on business logic or data access, and completely ignore security requirements at that time. An example of robert martin's old open clothes principle. But i have a lot of reverse ability that i can retefet security, either authentication, authorization, by adding these clean wrappers without having to modify my existing code. So thtat enables me to to worry about one, a few things at a time and evolve a system that does imply that up front, you have to make some technological decisions that allow for that kind of approach.
