Looking for documents, presentations, or training material regarding the security aspects of dhis2

Hello everyone, I’ve been lately reading about the security aspects of dhis2, I’ve been scanning the database and codebase and documentation to get a good grasp on the subject and also to learn from the way dhis2 security is structured. the documentation is good, but I wonder if anyone may have other documents, presentations, or some training material beside the documentation that might help to acquire more info about the subject and get me faster on this path and give me a wider overview on the user roles, the Authorization and Authentication process, and the structure as a whole, any document or diagrams that might help would be appreciated.

thank you in advance,
