Reading through this documentation carefully will ensure that you get the most out of your NetDe-
fendOS product. In addition to this document, the reader should also be aware of the companion
volumes:
• The NetDefendOS CLI Guide which details all NetDefendOS console commands.
• The NetDefendOS Log Reference Guide which details all NetDefendOS log event messages.
These documents together form the essential documentation for NetDefendOS operation.
Note
High Availability, Anti-Virus, Web Content Filtering and ZoneDefense are not avail-
able with some models as specified in the chapters relating to those features.
For more information about the IDP capabilities of NetDefen-
dOS, please see Section 6.3, "Intrusion Detection and Preven-
tion".
NetDefendOS features integrated gateway anti-virus function-
ality. Traffic passing through the gateway can be subjected to
in-depth scanning for viruses, and attacking hosts can be
blocked and black-listed at your choice. Section 6.4,
"Anti-Virus", provides more information about how to use
the integrated anti-virus feature.
NetDefendOS provides various mechanisms for filtering web
content that is deemed inappropriate according to your web
usage policy. Web content can be blocked based on category,
malicious objects can be removed and web sites can be
whitelisted or blacklisted in multiple policies. For more in-
formation, please see Section 6.5, "Web Content Filtering".
A device running NetDefendOS is highly suitable for parti-
cipating in a Virtual Private Network (VPN). NetDefendOS
supports IPsec, L2TP and PPTP based VPNs concurrently,
can act as either server or client for all of the VPN types, and
can provide individual security policies for each VPN tunnel.
Virtual Private Networking is covered in detail by Chapter 9,
Virtual Private Networks.
With the support of Traffic Shaping, Threshold Rules and
Server Load Balancing features, NetDefendOS is optimal for
traffic management. The Traffic Shaping feature enables fine-
granular limiting and balancing of bandwidth; Threshold
Rules allows for implementing various types of thresholds
where to alarm or limit network traffic, and Server Load Bal-
ancing enables a device running NetDefendOS to distribute
network load to multiple hosts. Chapter 10, Traffic Manage-
ment, provides more detailed information on the various
traffic management capabilities.
To facilitate management of a NetDefendOS device, adminis-
trative control is enabled through a Web-based User Interface
or via the Command Line Interface. In addition, NetDefen-
dOS provides very detailed event and logging capabilities and
support for monitoring using standards such as SNMP. For
more information, please see Chapter 2, Operations and
Maintenance.
NetDefendOS can be used to control D-Link switches using
the ZoneDefense feature.
