Abstract
A hierarchical system firewall, comprising a root security manager, secondary security managers, a firewall controller, and firewalls. The root security manager designates a secondary security manager and allocates a system resource for each domain cluster, and provides firewall configuration schemes between the domain clusters. The secondary security managers add domain identifiers for hosts and devices of domain clusters, and provides a firewall configuration scheme for each domain. The firewall controller adds domain cluster identifiers for the hosts and devices in the system, and adds identification for the secondary security managers; allocates domain identification for a host and a device of a current domain cluster; and configures access permissions for the firewall of each device in the current domain cluster. The firewalls perform permissions control for access to a current device by hosts from different domains or different domain clusters. Further provided in the present invention is a configuration method for the hierarchical system firewall, simplifying system design, and improving system security.
