Each user is represented by an accessor element (ACEE)-an in‑memory reflection of the user's record in the database. CA Access Control builds the accessor element during the login process. The accessor element is associated with the user's process. Whenever the process requests a system service that is protected by CA Access Control, or issues an implicit request to access a resource, CA Access Control accesses the resource's record. It then determines whether the information in the previously created accessor element-such as the user's security level, mode, and group-lets the user access the resource.
