6 Barracuda Control Server Administrator’s Guide

Overview

The Barracuda Control Server web interface enablesadministrators to monitor and configure multiple

Barracuda Networks products from a single console. Through the web interface, you can check the

health of all connected devices, run reports that are generated by gathering data from all the devices,

and assign roles with varied permissions to different types of users.

The Barracuda Control Server web interface provides for convenient configuration and management

of multiple Barracuda Networks device settings, while providing a view of each device web interface

for individual configuration or reporting.

Key statistics can be viewed by device type at a glance on the CLOUD CONTROL >Status page of the

web interface with the ability to drill down for more detail into the individual web interface for each

connected device.

This guide walks you through installation and initial configuration of your Barracuda Control Server,

and provides concepts and examples to help you understand how to manage Barracuda Networks

products with the Barracuda Control Server web interface according to your organization’s

deployment needs and security policies.

Concepts

Understanding these concepts enables you to take full advantage of the Barracuda Control Server

features for configuring and synchronizing settings on individual or groups of Barracuda Networks

products.

Administrator Access

There are two different administrator accounts:

•Barracuda Control Server Administrator Account – Manage and configure the Barracuda

Control Server. To configure and manage the Barracuda Control Server, log into the system

using admin as your user name and password. Once logged in, you can view and manage the

device, update security definitions, manage the displayed image, troubleshoot the device, and

view tasks and task errors.

•Barracuda Control Server Account Admin – Manage and connect products through the

Barracuda Control Server web interface. Create users and assign various permissions to each

user for access to the Barracuda Control Server, connect devices, and view device status.

Use the web interface to link your Barracuda Network devices including:

• Barracuda Spam Firewall

• Barracuda Web Filter

• Barracuda Web Application Firewall

• Barracuda Message Archiver

• Barracuda Link Balancer

• Barracuda Load Balancer

When you log in to the Barracuda Control Server as the account admin, the connected devices display

in the left pane.

Management Contexts

There are three ‘contexts’ you use to administer the Barracuda Control Server web interface and the

connected products. These contexts include:

•TheCloud Control context; for managing Barracuda Control Server web interface

configuration;

•TheProduct context; for managing an individual Barracuda Networks product using the

product web interface;

•TheGroup context; for managing a group of the same type of Barracuda Networks products

with one web interface, or for grouping products by company, location, or department.

These contexts are described briefly below.

Cloud Control Context

When you log into the Barracuda Control Server web interface, you first see the Cloud Control

context–on the CLOUD CONTROL > Status page–which displays a snapshot of product traffic

statistics for the connected Barracuda Networks product(s).

The Cloud Control pane on the left displays either a list of individual products connected to the

Barracuda Control Server, or groups of products which you create:

8 Barracuda Control Server Administrator’s Guide

The center pane provides an interface for managing your account and for connecting products, as well

as a snapshot of product traffic statistics for all connected products. The Unit Health pane on the right

includes a performance overview, connectivity, firmware, storage, and subscription status for each

individual product organized by product type:

Once you click on an individual product, either in the Cloud Control pane or in the Unit Health pane,

you leave the ‘Cloud Control context’ and drill-down into the product type web interface. The product

web interface displays activity for an individual product if you have only one of that type connected.

If you have multiple of one product type connected, the settings and statistics for all products of that

type display in one web interface as described below.

Group Context

Grouping Barracuda Networks products enables you to manage settings and apply policies across

multiple Barracuda Networks products of the same type from one web interface. You can also use

“grouping” to organize your Barracuda Networks products by location, company, department, etc.,

and you can include products of different types. Grouping happens in one of two ways:

1. By default, the Barracuda Control Server groups Barracuda Networks products by

product type. For example, if you have two or more Barracuda Web Application Firewalls

connected to a Barracuda Control Server, they are automatically grouped as such. You can then

click on that product type in the Cloud Control pane and see one web interface with aggregated

statistics and settings for all of the devices within that group. From the web interface, you can

set policies for all of the products in the group at the same time since they are the same product

type. This group context also enables reporting on aggregated statistics across a group.

2. You can create a grouping of two or more products. When you click on that group in the Cloud

Control pane, aggregated statistics display on the Status page for each product type in the group.

Additional reasons to manage products in the group context include:

• If you have many devices in one or more locations, managing them with a central console

enables you to easily track firmware versions across products and keep them up-to-date.

• Grouping devices by location helps you keep track of where each device is physically

located in case it needs service. As long as the unit is joined to the Barracuda Control

Server, you do not need to look up the admin password to configure or update the product.

• Grouping devices of the same type enables viewing ‘exceptions’ in which values for the

same setting differ across the devices.

• Grouping either devices of the same type or of different types provides a performance and

traffic statistic snapshot on the CLOUD CONTROL > Status page for each device in the

group. Statistics are aggregated for devices of the same type.

Product Context

If you have only one of any Barracuda Networks product type connected to the Barracuda Control

Server, when you click on that product link in the Cloud Control pane or in the Unit Health pane, the

web interface for that individual device displays. From the product web interface, you manage the

individual settings just as you would if you logged into the device directly.

Exceptions

When you have more than one of a Barracuda Networks product type connected to the Barracuda

Control Server, and you view the settings of all of them as a group (with one web interface as

described above), a yellow Exception ( ) icon displays if the value of the setting is not the same on

all devices in the group. When you hover the mouse over the icon, the Barracuda Control Server

clearly indicates what the values for that setting are on each device, so that you can change the settings

if desired. See Dealing With Exceptions for more information and examples.
