About ProCurve Identity Driven Manager

Introduction

Network usage has skyrocketed with the expansion of the Internet, wireless,

and convergence technologies. This increases the burden on network manag-

ers working to control network usage. Also, the complexity of large networks

makes it difficult to control network access and usage by individual users.

ProCurve Identity Driven Manager (IDM) is an add-on module to the ProCurve

Manager plus (PCM+) application that extends the functionality of PCM+ to

include authorization control features for edge devices in networks using

RADIUS servers and Web-Authentication, MAC-Authentication, or 802.1x

security protocols.

Using IDM simplifies user access configuration by automatically discovering

Microsoft IAS RADIUS Servers, Realms, and users. You can use IDM to

monitor users on the network, and to create and assign "access policies" that

work to dynamically configure edge switches and manage network resources

available to individual users. Using IDM, access rights, quality of service

(QoS), and VLAN enrollment are associated with a user and applied at the

point of entry or "edge" of the network.

About ProCurve Identity Driven Manager

Introduction

Why IDM?

Today, access control using a RADIUS system and ProCurve devices (switches

or wireless access points) is typically made up of several steps.

Figure 1-2. Current Access Control process

1. A client (user) attempts to connect to the network.

2. The edge device recognizes a connection state change, and requests

identifying information about the client. This can include MAC address,

username and password, or more complex information.

3. The switch forwards an access request, including the client information

to the authentication server (RADIUS).

4. The RADIUS server validates the user’s identity in the user directory,

which can be an Active Directory, database or flat file. Based on the

validation result received from the user directory, the authentication

server returns an accept or deny response to the switch.

5. If the user is authenticated, the ProCurve device grants the user access to

the network. If the user is not authenticated, access is denied.

For networks using IDM, access control is enhanced to include authorization

parameters along with the authentication response. IDM enhances existing

network security by adding network authorization information, with access

and resource usage parameters, to the existing authentication process. Using

IDM you can assign access rights and connection attributes at the network

switch, with dynamic configuration based on the time, place, and client that

is generating the access request.

1-4

About ProCurve Identity Driven Manager

Introduction

When using IDM, the authentication process proceeds as described in the first

three steps, but from that point the process changes as follows:

4. The RADIUS server validates the user’s identity in the user directory.

Based on the validation result received from the user directory, the

authentication server returns an accept or deny response to the switch. If

the user is accepted (authenticated), the IDM Agent on the RADIUS server

processes the user information. IDM then inserts the network access

rights configured for the user into the Authentication response sent to the

switch.

5. If the user is authenticated, the switch grants the user access to the

network. The (IDM) authorization information included in the authenti-

cation response is used to configure VLAN access, QoS and Bandwidth

parameters for the user, and what network resources the user can access

based on time and location of the user’s login.

If the user is authenticated by the RADIUS server, but IDM’s authorization

data indicates that the user is attempting to access the network at the

wrong time, or from the wrong location or system, the user’s access

request is denied by IDM.

Figure 1-3. Access Control using IDM

If a user is authenticated in RADIUS, but is unknown to IDM, IDM will not

override RADIUS authentication and default switch settings, unless you

configure it to do so. You can create a "guest" profile in IDM to provide

limited access for unknown users.

About ProCurve Identity Driven Manager

Introduction

IDM Architecture

In IDM, when a user attempts to connect to the network through an edge

switch, the user is authenticated via the RADIUS Server and user directory.

Then, IDM is used to return the user’s "access profile" along with the authen-

tication response from RADIUS to the switch. The IDM information is used to

dynamically configure the edge switch to provide the appropriate authoriza-

tions to the user, that is, what VLAN the user can access, and what resources

(QoS, bandwidth) the user gets.

The following figure illustrates the IDM architecture and how it fits in with

RADIUS.

Figure 1-4. IDM Architecture

IDM consists of an IDM Agent that is co-resident on the RADIUS server, and

an IDM Server that is co-resident with PCM+. Configuration and access

management tasks are handled via the IDM GUI on the PCM+ management

workstation.

The IDM agent includes:

• A RADIUS interface that captures user authentication information

from the RADIUS server and passes the applicable user data (user-

name, location, time of request) to the IDM Decision Manager. The

interface also passes user access parameters from IDM to the RADIUS

server.

1-6

About ProCurve Identity Driven Manager

Introduction

• A Decision Manager that receives the user data and checks it against

user data in the local IDM data store. Based on the parameters defined

in the data store for the user data received, the Decision Manager

outputs access parameters for VLAN, QoS, bandwidth, and network

resource access to the RADIUS interface component.

• A Local Data Store that contains information on Users and the Access

Policy Groups to which the user belongs. The Access Policy Group

defines the rules that determine the user’s access rights.

The IDM Server provides configuration and monitoring of Identity Driven

Manager. It operates as an add-on module to PCM+, using the PCM model

database to store IDM data, and a Windows GUI (client) to provide access to

configuration and monitoring tools for IDM.

You use the IDM GUI to monitor IDM Agent status and users logged into the

network, and to manage IDM configuration, including:

• Defining access parameters for the network, such as locations, times,

network resources, and access profiles.

• Creating access profiles that define the network resources and

attributes (VLAN, QoS, bandwidth) assigned to users in an Access

Policy Group.

• Creating Access Policy Groups with rules (access policies) that will

be assigned to users in that Group.

• Assigning users to Access Policy Groups.

• Deploying IDM configuration data to the IDM Agent on the RADIUS

server.
