Anti-Virus NetDefendOS features integrated gateway anti-virus
functionality. 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 Scanning”, provides more information about how
to use the integrated anti-virus feature.
Web Content Filtering 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
information, please see Section 6.3, “Web Content Filtering”.
Virtual Private Networking A device running NetDefendOS is highly suitable for
participating
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, VPN.
Traffic Management 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
Balancing enables a device running NetDefendOS to
distribute network load to multiple hosts. Chapter 10, Traffic
Management, provides more detailed information on the
various traffic management capabilities.
Operations and Maintenance To facilitate management of a NetDefendOS device,
administrative control is enabled through a Web-based User
Interface or via the Command Line Interface. In addition,
NetDefendOS provides very detailed event and logging
capabilities and support for monitoring using standards such
as SNMP. For more information, please see Chapter 2,
Management and Maintenance.
ZoneDefense NetDefendOS can be used to control D-Link switches using
the ZoneDefense feature.
