Using the Avaya Endpoint Access Control Agent
designed to help administrators maintain the health of the computers on the network, which in
turns helps maintain the overall integrity of the network. It is not designed to secure a network
from malicious users. For example, if a computer has all the software and configurations that
the network access policy requires, the computer is considered healthy or compliant and it is
granted the appropriate access to the network. NAP does not prevent an authorized user with
a compliant computer from uploading a malicious program to the network or engaging in other
inappropriate behavior.
A NAP Enforcement Client (EC) requests some level of access to a network, passes the
computer's health status to a NAP enforcement point that is providing the network access.
NAP enforcement points are computers or network access devices that use NAP or can be
used with NAP to require the evaluation of a NAP client's health state and provide restricted
network access or communication. If the computer's health is not compliant, the NAP EC
indicates the restricted status of the NAP client to other components of the NAP client
architecture.
Avaya NAP Enforcement Client
The Avaya NAP Enforcement Client is a key component of Avaya EAC Agent. It is automatically
installed on client's computer with Avaya EAC Agent. The Avaya NAP Enforcement Client is
responsible for requesting access to a network, communicating a client computer's health
status to the NAP server that is authorizing the network access, and communicating the
connection status of the client computer to other components of the NAP client architecture.
The NAP server is configured by the VPN gateway.
The Avaya EAC Agent sends the health status to the Avaya NAP Enforcement Client once the
SRS rule is checked.
Viewing the Avaya NAP Enforcement Client Status
After the user establishes a VPN connection the Avaya EAC Agent checks the SRS rule. If the
rule check fails then the Avaya NAP Enforcement Client automatically pops-up a system tray
balloon and notifies the user.
To view more details, open the Network Access Protection dialog using one of the following
methods:
• click the pop-up balloon;
• click the Action Center icon in system tray and select Network Access Protection
(important);
