![]() Lastly, if you integrate ISE with mobility services engine (MSE), then you can track the actual physical location of the wireless endpoint as it moves. thereby, it is telling us which location the wireless user or device is. In a wireless network the access point’s call station ID can be defined with the location name. If it is coming in from a switch, that is labeled as a SJC-19 location, then you can apply specific policies. When you author time-based policies within ISE, you can in one simple way, determine the location which has a location label assigned to the network devices and then tracking where the authentication request is coming in from. The end result is that you will see endpoint profile associate to the endpoints MAC address telling us what device it is. Once ISE receives the attributes, based on the profiling policy, it can classify the endpoint into specific device groups and with the help of a feed service you can keep the profiling policies up to date. ![]() So either these traffic somehow hits directly to ISE, or you can use this tiny feature on the network devices called the device sensor(DS) that caches such interesting traffic and passes it on to the ISE over RADIUS. For example, the DHCP class identifier as MSFT tells ISE that it’s a Microsoft workstation. ![]() Each endpoint that shows up in the network sends out some interesting traffic that reveal the endpoint type. Once someone authenticates, ISE builds a session table listing all the users and their specific association to the network. That’s quite a lot what Cisco ISE can deliver however when you look at enterprises today, they do have some infrastructure running that already has some of these identity services like Microsoft Active Directory or an LDAP server.īasically, the endpoints want to connect to the network, the network devices gate the access, then Cisco ISE determines who should get what level of access by resolving the identity from the external identity sources. ISE can talk up to hundred thousand network devices, can support up to 1.5 million endpoints, 300,000 internal user accounts, 1 million guest user accounts and 1 million user certificates that can be issued from ISE. So with all this in consideration, how does ISE fare in terms of identity based access? Cisco ISE centrally knows what are all the endpoints in the network and where they are located. So once you revealed your identity to ISE, it determines the level of your level of access based on the generated a session ID that the endpoint sent to the ISE once it got connected. In addition, authentication typically ends with an authorization. So, essentially, with authentication you tell ISE who you are. Now these credentials reach ISE in a process called authentication.Īlso, there are various authentication protocols that an enterprise can use depending on the type of network and endpoint. With the help of credentials such as password, certificates, tokens or at least the endpoints MAC address. Network devices are the main avenues for wired network, Wireless and VPN connection to allow the users and the endpoint to connect to the network to access various services. Cisco Identity Service Engine (ISE) is a network access control and policy enforcement platform.
