### realm

Domain for a set of security features. The realm organizes security information and defines its range of operations. A realm has its own idea of principals, permissions, and ACLs. Particular security domains are reflected in Java as realm instances. A realm determines how a user is authenticated and retrieves access control lists for given names.
