Models at a glance

There are some high-level models that most environments use to manage certificates. In the next few sections, we will uncover these models and the requirements and permissions needed to succeed with them. The Financial Company has already applied the self-service registration model as part of the manager-initiated model. The models are not explicit, but they are flexible, and TFC could use a mixture of both. Let's now look at the centralized management model.
