EAP Security & Server Certificates
Overview
The following EAP types all support a server certificate:
EAP-PEAP
EAP-TTLS
EAP-TLS
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. 90). 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.
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.
