What level of user access control can be implemented in a custom web application?
In a custom web application, various levels of user access control can be implemented to ensure the security and integrity of the system. These levels include basic authentication, role-based access control (RBAC), and attribute-based access control (ABAC). Basic authentication involves verifying the identity of users through login credentials. RBAC assigns different roles to users, such as admin, manager, or user, and provides access permissions based on these roles. ABAC takes into consideration various attributes of users, such as location, time, and device, to determine access rights.
