    SNS - USER CONFIGURATION MANUAL V.3 WELCOME Backed by the Common Criteria, Stormshield Network advises taking into consideration the recommendations of use for the Administration Suite and Firewall product stated below. These recommendations set out the usage requirements by which to abide in order to ensure that your Firewall operates within the context of the common criteria certification.

    Example no DHCP, DNS, PKI, application proxies, etc.* Stormshield Network appliances are not configured to forward IPX, Netbios, AppleTalk, PPPoE or IPv6 information flows. Firewall-VPN appliances do not depend on external “online” services (DNS, DHCP, RADIUS, etc.) to apply the information flow control policy.
  • Page 14 The usage mode subject to evaluation excludes the fact that the TOE relies on services other than PKI, DNS and DHCP servers and proxies. The optional modules provided by Stormshield Network to manage these services are disabled by default and have to stay that way.

    To round up this chapter on creating user awareness of network security, the administrator has to tackle the management of user access. In fact, a Stormshield Network Firewall’s authentication mechanism, like many other systems, is based on a login/password system and does not necessarily mean that when the application enabling this authentication is closed, the user is logged off.
  • Page 18 Remind users to lock their sessions before they leave their workstations unattended. This seemingly tedious task can be made easier with the use of authentication mechanisms which automate session locking (for example, a USB token).
