Managing NetDefendOS 2.1.1. Overview NetDefendOS is designed to give both high performance and high reliability. Not only does it provide an extensive feature set, it also enables the administrator to be in full control of almost every detail of the system. This means the product can be deployed in the most challenging environments. A good understanding on how NetDefendOS configuration is performed is crucial for proper usage of the system. For this reason, this section provides an in-depth presentation of the configuration subsystem as well as a description of how to work with the various management interfaces. Management Interfaces NetDefendOS provides the following management interfaces: The WebUI The Web User Interface (WebUI) provides a user-friendly and intuitive graphical management interface, accessible from a standard web browser. The CLI The Command Line Interface (CLI), accessible locally via serial console port or remotely using the Secure Shell (SSH) protocol, provides the most fine-grain control over all parameters in NetDefendOS. Note Microsoft Internet Explorer (version 6 and later), Firefox and Netscape (version 8 and later) are the recommended web-browsers to use with the WebUI. Other browsers may also provide full support. Access to remote management interfaces can be regulated by a remote management policy so the administrator can restrict management access based on source network, source interface and credentials. Access to the web interface can be permitted for administrative users on a certain network, while at the same time allowing CLI access for a remote administrator connecting through a specific IPsec tunnel. By default, Web User Interface access is enabled for users on the network connected via the LAN interface of the firewall (on products where more than one LAN interface is available, LAN1 is the default). 2.1.2.
