1.1. About D-Link NetDefendOS Chapter 1. Product Overview Anti-Virus Web Content Filtering Virtual Private Networking Traffic Management Operations and Maintenance ZoneDefense hosts. For more information about the IDP capabilities of NetDefendOS, please see Section 6.5, "Intrusion Detection and Prevention". 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. 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". 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. 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. 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. NetDefendOS can be used to control D-Link switches using the ZoneDefense feature. Reading through this documentation carefully will ensure that you get the most out of your NetDefendOS 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 available with some models as specified in the chapters relating to those features. 15
