How the eTrust Agent for Cisco NAC Works

The eTrust Agent for Cisco NAC discovers the posture attributes for Computer

Associates applications on an end-point device that attempts to access or use

resources on a network administered with Cisco NAC. The Cisco Trust Agent

(CTA), also located on the end-point device, passes the posture attributes to a

Cisco Access Control Server (ACS). The ACS compares the posture attributes

with a set of policies previously defined by a network administrator. Based on

the results of the comparison, the end-point device may either be granted full

primary network access or placed into a separate virtual network, where the

device can go through a remediation process before it is allowed to connect to the

primary network.

Product Components

Overview 7

Product Components

The eTrust Agent for Cisco NAC consists of the following components:

cai-pp.txt

The cai-pp.txt file contains information for Computer Associates applications

in the form of attribute/value pairs. You use this file with the CSUtil.exe

program to add the Compute Associates product attribute definitions to the

Cisco Secure ACS NAC database.

cai-pp.dll

The cai-pp.dll file is the eTrust Agent for NAC, which discovers the posture

attributes of Computer Associates applications running on an end-point

device. You use the CAPPInstall.exe program to install the plug-in on an

end-point device.

cai-pp.inf

The cai-pp.inf file contains the eTrust Agent attribute definitions. The Cisco

Trust Agent uses this file to communicate Computer Associates product

attributes to the Cisco Secure ACS database.

Setting Up eTrust Agent for Cisco NAC 9

Chapter 2: Setting Up eTrust Agent for

Cisco NAC

This chapter contains procedures for setting up eTrust Agent for Cisco NAC. The

set up process includes:

Adding Computer Associates attributes to the Cisco Secure ACS NAC

database

Installing the Cisco Trust Agent on all end-point devices

Installing the eTrust Agent for Cisco NAC on all end-point devices

Verifying the installation

Note: The procedures in this chapter assume Cisco NAC is currently running in

your network environment and is administered with Cisco Secure ACS 3.3.

Add Computer Associates Attributes to the NAC Database

10 Installation Guide

Add Computer Associates Attributes to the NAC Database

Before you can define policies for Computer Associates posture attributes, you

must first add the attribute/value pairs to the Cisco Secure ACS NAC database.

Note: The following procedure assumes Cisco Secure ACS 3.3 is installed at:

C:\Program Files\CiscoSecure ACS v3.3

To add Computer Associates attributes to the Cisco Secure ACS NAC database,

follow these steps:

1. Go to the Computer Associates SupportConnect website,

http://supportconnect.ca.com, and locate the eTrust Agent for Cisco NAC.

2. Download the eTrust Agent for Cisco NAC to a system typically used for

network management tasks.

3. Extract the contents of the downloaded zip file to a temporary directory,

such as C:\Temp.

4. On the Cisco Secure ACS 3.3 for Windows system, copy the file cai-pp.txt to:

C:\Program Files\CiscoSecure ACS v3.3\Utils

The cai-pp.txt file contains the attribute/value pairs for NAC-enabled

Computer Associates applications.

5. From the C:\Program Files\CiscoSecure ACS v3.3\Utils directory, run the

following command:

CSUtil.exe -addavp cai-pp.txt

The CSUtil.exe program adds the attribute/value pairs to the Cisco Secure

ACS NAC database.

Use the Cisco Secure ACS user interface to configure policies for Computer

Associates products. For instructions, refer to the Cisco document NAC User

Guide for Cisco Secure ACS 3.3.

Install the Cisco Trust Agent

Install the Cisco Trust Agent on all end-point devices, such as desktop

computers, workstations, laptops, and servers that connect to or use network

resources. Download and install the Cisco Trust Agent 1.0 from the Cisco
