Cisco 4400 validating identity radius fairly medium to slim dating retired
Here is how to implement 802.1X authentication in a Windows Server 2008 R2 domain environment using Protected-EAP authentication.I have designed the tutorial to be worked on in the specific order to prevent downtime if deployed during the day.Creating the policy is not difficult; what becomes challenging is the identification of the attribute to use, because Source-SSID is not a field in a RADIUS packet.The attribute you need to use is called-station-id.Looking at the predefined MAB rule, this rule uses the Default Network Access list of allowed protocols (which is almost every supported authentication protocol). From the ISE GUI, perform the following steps: This section examines the most common authentication protocols seen in most environments, so you can create a more specific list of allowed protocols for your deployment.Let’s follow Figure 13-6, from top-down: Extensible Authentication Protocol (EAP) Types EAP is an authentication framework providing for the transport and usage of identity credentials.That is the field that describes the wireless SSID name.
From the ISE GUI, navigate to Policy Rules are processed in a top-down, first-match order; just like a firewall policy.
If the MAC address is known, it is considered to be a successful MAB (notice it was not termed successful ).
MAB is exactly that, bypassing authentication, and it is not considered a secure authentication.
This rule will be configured to This completes the creation of the authentication rule.
Determining what actions to take for the authentications that passed is handled in the Authorization Policy.
Very often, authentications for a remote-access VPN connection get routed to an OTP server, like RSAs Secure ID.
