how to choose a security model
I am looking for the best security model to implement access rights on a website. Objects access should be granted based on the following rules initially:
 - User
 - User Group
 - Hierarchy
 - Permissions (CRUD)

What are the security models I can use and what are the advantages and disadvantages of each one?

Thank you!
