Azure Security is a combination of best practices and a combination of services and products configured by admins to protect identities and services.
Security in Azure starts by building your directory (Azure AD) and assigning the corresponding roles to your cloud users, using the least privilege either by assigning from a multiple built in roles created for the most common task-oriented users or by creating a custom one that will fit your roles requirements. You will use the Role Based Access Control (RBAC) to assign the roles.
It is important to consider the Hierarchy with RBAC, because assigning a role at a specific level will inherit the permissions down the hierarchy:

In addition, you will find features like Just in Time Access, to help protect admin access, assigning a temporary access to administrators and protecting those identities.
