2.4.3. Auto-Update Mechanism
A number of the NetDefendOS security features rely on external servers for automatic updates and
content filtering. The Intrusion Prevention and Detection system and Anti-Virus modules require ac-
cess to updated signature databases in order to provide protection against the latest threats.
To facilitate the Auto-Update feature D-Link maintains a global infrastructure of servers providing
update services for D-Link Firewalls. To ensure availability and low response times, NetDefendOS
employs a mechanism for automatically selecting the most appropriate server to supply updates.
For more details on these features see the following sections:
• Section 6.3, "Intrusion Detection and Prevention"
• Section 6.4, "Anti-Virus"
• Section 6.5, "Web Content Filtering"
• Appendix A, Subscribing to Security Updates
Note
Backups include only static information in the firewall configuration. Dynamic inform-
ation such as the DHCP server lease database will not be backed up.
