8.2. Authentication Setup

8.2.1. Setup Summary

The following list summarizes the steps for User Authentication setup with NetDefendOS:
• Have an authentication source which consists of a database of users, each with a
username/password combination. Any of the following can be an authentication source:
i. A local user database internal to NetDefendOS.
ii. A RADIUS server which is external to the NetDefend Firewall.
iii. An LDAP Server which is also external to the NetDefend Firewall.
• Define an Authentication Rule which describes which traffic passing through the firewall is to
be authenticated and which authentication source will be used to perform the authentication.
These are described further in Section 8.2.5, "Authentication Rules".
• If required, define an IP object for the IP addresses of the clients that will be authenticated.
This can be associated directly with an authentication rule as the originator IP or can be
associated with an Authentication Group.
• Set up IP rules to allow the authentication to take place and also to allow access to resources
by the clients belonging to the IP object set up in the previous step.
The sections that follow describe the components of these steps in detail. These are:
• Section 8.2.2, "Local User Databases"
• Section 8.2.3, "External RADIUS Servers"
• Section 8.2.4, "External LDAP Servers"
• Section 8.2.5, "Authentication Rules"

8.2.2. Local User Databases

A Local User Database is a registry internal to NetDefendOS which contains the profiles of
authorized users and user groups. Combinations of usernames/password can be entered into
these with passwords stored using reversible cryptography for security. By default, a single local
user database exists called AdminUsers. Extra databases can be created by the administrator as
required.
Example 8.1. Creating a Local User Database
This example shows how to create a new user database called lan_users.
