After this submission, the network permission is automatically removed and R1 will no longer access to R2. Network permissions are just an example of permissions that HiPoP takes into account, but it also manages file permissions (tasks are only authorized to read and write files in a temporary directory identified by them). Moreover, tasks can not read information on the resource system (hostname, IP address, type of the resource, OS used) and can not modify the administration system like overload the security manager, added some additional permissions.

Company B. Case Study for High-Level Security Architecture Internal users are better protected from the Internet attacks than in the previous type of architecture, due to the two firewalls. The Internet Web and DNS servers are located on a DMZ of the “external” firewall because incoming traffic addressed to these two servers comes mainly from external area. In order to improve the filtering level of some sensitive servers like intranet Web, some ad- ditional proxies can be added. For instance, an HTTP proxy for intranet Web can be installed in the MoIP DMZ to do users’ authentication but also high control on HTTP data (format and content).

A user in a federated zone can request a resource located by the resource broker to be in a different zone. SSH server C will request SSH server A’s public key from the DNSSec server. Using IPSec, the two sites will be able to establish pairwise VPN links. In a third phase, when SSH servers’ keys change (due to compromised keys, or security maintenance to renew keys), the DNSSec server will update its SSH keys record files (7). edu) system provides a fine mechanism of authorization. Each resource contains a list of objects which can access it.
