EAP Security's Using Server Certificates - Overview

The following EAP types all support a server certificate:



All three of these certificate-using security methods are documented in the following sections. EAP
Authentication goes a step beyond just encrypting data transfers, but also requires that a set of credentials be
validated before the client (panel) is allowed to connect to the rest of the network (FIG. 110). Below is a
description of this process. It is important to note that there is no user intervention necessary during this
process. It proceeds automatically based on the configuration parameters entered into the panel.

FIG. 110 EAP security method in process
A server certificate file uses a certificate that is installed in a panel so that the RADIUS server can be validated
before the panel tries to connect to it. The field name associated with this file is Certificate Authority.
If a server certificate is used, it should first be downloaded into the panel and the Certificate Authority field
should then be set to the name of that certificate file. No file path should be used for this setting as all
certificates are stored in a specific directory that the user cannot control or change. The most secure connection
method uses a server certificate.
If no server certificate will be used then, this field should be left blank. If the field contains a file name, then a
valid certificate file with the same file name must be previously installed on the panel. Otherwise the
authentication process will fail.

EAP (Extensible Authentication Protocol) is a Enterprise authentication protocol that can be used in both a
wired and wireless network environment. EAP requires the use of an 802.1x Authentication Server, also
known as a Radius server. Most of the configuration fields described below take variable length strings as
inputs. Whenever these fields are selected, an on-screen keyboard appears which allows the string to then be
entered.
PEAP (Protected Extensible Authentication Protocol) was developed by both Cisco
as a way to securely transmit authentication information, such as passwords, over a wireless network
environment. PEAP uses only server-side public key certificates and therefore does not need a client (panel)
certificate which makes the configuration and setup easier.
There are two main versions of the PEAP protocol supported by panel's Devicescape Wireless Client are:



120
EAP-PEAP
EAP-TTLS
EAP-TLS
802.1x
(EAP over Wireless)
(Wireless Access Point)
PEAPv0 (developed with Microsoft)
PEAPv1 (developed exclusively by Cisco)
PEAP uses an inner authentication mechanism which is supported by the Devicescape Wireless
Client, the most common of which are:
MSCHAPv2 with PEAPv0 and

GTC with PEAPv1

LAN
Authentication Server
Authenticator
