2.1. 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.

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.

subsystem as well as a description of how to work with the various management interfaces.
Management Interfaces
NetDefendOS provides the following management interfaces:
The Web Interface
The Web Interface (also known as the Web User Interface or WebUI) is
built into NetDefendOS and provides a user-friendly and intuitive
graphical management interface, accessible from a standard web
browser (Microsoft Internet Explorer or Firefox is recommended).

The browser connects to one of the hardware's Ethernet interfaces using
HTTP or HTTPS and the NetDefendOS responds like a web server,
allowing web pages to be used as the management interface.

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-grained control over all parameters in NetDefendOS.

Secure Copy
Secure Copy (SCP) is a widely used communication protocol for file
transfer. No specific SCP client is provided with NetDefendOS
distributions but there exists a wide selection of SCP clients available
for nearly all workstation platforms.
