Cisco ISE with cisco-av-pair

Hi All
I am deploying a Cisco ISE together with a WLC to provide guest services. After the authentication the users will be redirected to the device registration page, this is done via the radius attribute "cisco-av-pair = url-redirect=https://FQDN:8443/guestportal/gateway?sessionId=SesionIdValue&portal=..." returned by the ISE. My problem is that there is no internal DNS server in the guest network (point to public DNS servers), so the clients cannot resolve the FQDN. We can manually add the redirect URL, however the SessionIdValue in the URL is a dynamic value, is there a way to put a dynamic value in the attributes manually?
Thanks a lot!
Leo

Thanks Tarik, I saw u helped a lot of ppl on ISE configuration, really appreciate for your help.
In ISE there is a place to set the default URL for Sponsor and My device, not sure why not for Guest portal. As the DNS server is not available at this moment, we are using the WLC to do the redirect (so not CWA), the downside is we cannot have a whitelist since all request will be redirected to the guest portal.

Cisco ISE with both internal and External RADIUS Server

Hi
I have ISE 1.2 , I configured it as management monitor and PSN and it work fine
I would like to know if I can integrate an external radius server and work with both internal and External RADIUS Server simultanously
So some computer (groupe_A in active directory ) will continu to made radius authentication on the ISE internal radius and other computer (groupe_B in active directory) will made radius authentication on an external radius server
I will like to know if it is possible to configure it and how I can do it ?
Thanks in advance for your help
Regards
Blaise

Cisco ISE can function both as a RADIUS server and as a RADIUS proxy server. When it acts as a proxy server, Cisco ISE receives authentication and accounting requests from the network access server (NAS) and forwards them to the external RADIUS server. Cisco ISE accepts the results of the requests and returns them to the NAS.
Cisco ISE can simultaneously act as a proxy server to multiple external RADIUS servers. You can use the external RADIUS servers that you configure here in RADIUS server sequences. The External RADIUS Server page lists all the external RADIUS servers that you have defined in Cisco ISE. You can use the filter option to search for specific RADIUS servers based on the name or description, or both. In both simple and rule-based authentication policies, you can use the RADIUS server sequences to proxy the requests to a RADIUS server.
The RADIUS server sequence strips the domain name from the RADIUS-Username attribute for RADIUS authentications. This domain stripping is not applicable for EAP authentications, which use the EAP-Identity attribute. The RADIUS proxy server obtains the username from the RADIUS-Username attribute and strips it from the character that you specify when you configure the RADIUS server sequence. For EAP authentications, the RADIUS proxy server obtains the username from the EAP-Identity attribute. EAP authentications that use the RADIUS server sequence will succeed only if the EAP-Identity and RADIUS-Username values are the same.

Cisco ISE with AD Problem: "Could not read groups data: Global catalog not found"

Hi all,
When I make the ActiveDirectory integration with Cisco ISE, I have complete with this integration. but when I try to read the Groups from Active Directory, ISE shows the message "Could not read groups data: Global catalog not found".
My Domain has multiple sites and subnets, each contains GC for local logon. I have set ISE to the correct site and subnet. Forward and Reverse DNS are working with no error.
Does anyone get this problem, please help.
I have check into the ISE CLI Reference Guide 1.1.x
You are about to configure Active Directory settings.
Are you sure you want to proceed? y/n [n]: y
Parameter Name: dns.servers
Parameter Value: 10.77.122.135
Active Directory internal setting modification should only be performed if approved by ISE
support. Please confirm this change has been approved y/n [n]: y
What shoud I set in the Parameter Name ? dns.servers or my dns hostname ?
Please suggest for this too.
Thanks and Regards,
Pongsatorn M.

Hi Pongsatorn,
Thanks for the reply!
I've attached the results of the ISE detailed AD test. As you can see, there is a fair number of domain controllers in the AD forest.
It seems everything works correctly until it gets to testing the AD connectivity on port 3268. Then I get this:
Testing Active Directory connectivity:
    Global Catalog: pdascdc02.xyz.com
      gc:       3268/tcp - refused
Testing Active Directory connectivity:
    Global Catalog: pdascdc02.xyz.com
      gc:       3268/tcp - refused
For some reason, the request to the controllers on port 3268 is being refused.
Any thoughts you might have are greatly appreciated.
Cheers,
Greg

Cisco ISE with EAP-FAST and PAC provisioning

Hi,
I have search with no result on this topic. So, Does anyone have implemented Cisco ISE authentication with EAP-FAST and PAC provisioning ?
Since I have an issue with internal proxy, user required to authenticate with an internal proxy before granting access to the internet.
If you have any documents, it would be appreciated for me.
Thanks,
Pongsatorn

From what I understand a Internet proxy PAC and a eap-fast PAC are two different purposes.
Is that what you are trying to get clarification on.
Basically eap fast PAC provisioning is a PAC that s provisioned when a client authenticates successfully. The client provides this PAC for network authentication and not proxy authentication.

Cisco ISE with TACACS+ and RADIUS both?

Hello,
I am initiating wired authentication on an existing network using Cisco ISE. I have been studying the requirements for this. I know I have to turn on RADIUS on the Cisco switches on the network. The switches on the network are already programmed for TACACS+. Does anybody know if they can both operate on the same network at the same time?
Bob

Hello Robert,
I believe NO, they both won't work together as both TACACS and Radius are different technologies.
It's just because that TACACS encrypts the whole message and Radius just the password, so I believe it won't work.
For your reference, I am sharing the link for the difference between TACACS and Radius.
http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a0080094e99.shtml
Moreover, Please review the information as well.
Compare TACACS+ and RADIUS
These sections compare several features of TACACS+ and RADIUS.
UDP and TCP
RADIUS uses UDP while TACACS+ uses TCP. TCP offers several advantages over UDP. TCP offers a connection-oriented transport, while UDP offers best-effort delivery. RADIUS requires additional programmable variables such as re-transmit attempts and time-outs to compensate for best-effort transport, but it lacks the level of built-in support that a
TCP transport offers:
TCP usage provides a separate acknowledgment that a request has been received, within (approximately) a network round-trip time (RTT), regardless of how loaded and slow the backend authentication mechanism (a TCP acknowledgment) might be.
TCP provides immediate indication of a crashed, or not running, server by a reset (RST). You can determine when a server crashes and returns to service if you use long-lived TCP connections. UDP cannot tell the difference between a server that is down, a slow server, and a non-existent server.
Using TCP keepalives, server crashes can be detected out-of-band with actual requests. Connections to multiple servers can be maintained simultaneously, and you only need to send messages to the ones that are known to be up and running.
TCP is more scalable and adapts to growing, as well as congested, networks.
Packet Encryption
RADIUS encrypts only the password in the access-request packet, from the client to the server. The remainder of the packet is unencrypted. Other information, such as username, authorized services, and accounting, can be captured by a third party.
TACACS+ encrypts the entire body of the packet but leaves a standard TACACS+ header. Within the header is a field that indicates whether the body is encrypted or not. For debugging purposes, it is useful to have the body of the packets unencrypted. However, during normal operation, the body of the packet is fully encrypted for more secure communications.
Authentication and Authorization
RADIUS combines authentication and authorization. The access-accept packets sent by the RADIUS server to the client contain authorization information. This makes it difficult to decouple authentication and authorization.
TACACS+ uses the AAA architecture, which separates AAA. This allows separate authentication solutions that can still use TACACS+ for authorization and accounting. For example, with TACACS+, it is possible to use Kerberos authentication and TACACS+ authorization and accounting. After a NAS authenticates on a Kerberos server, it requests authorization information from a TACACS+ server without having to re-authenticate. The NAS informs the TACACS+ server that it has successfully authenticated on a Kerberos server, and the server then provides authorization information.
During a session, if additional authorization checking is needed, the access server checks with a TACACS+ server to determine if the user is granted permission to use a particular command. This provides greater control over the commands that can be executed on the access server while decoupling from the authentication mechanism.
Multiprotocol Support
RADIUS does not support these protocols:
AppleTalk Remote Access (ARA) protocol
NetBIOS Frame Protocol Control protocol
Novell Asynchronous Services Interface (NASI)
X.25 PAD connection
TACACS+ offers multiprotocol support.
Router Management
RADIUS does not allow users to control which commands can be executed on a router and which cannot. Therefore, RADIUS is not as useful for router management or as flexible for terminal services.
TACACS+ provides two methods to control the authorization of router commands on a per-user or per-group basis. The first method is to assign privilege levels to commands and have the router verify with the TACACS+ server whether or not the user is authorized at the specified privilege level. The second method is to explicitly specify in the TACACS+ server, on a per-user or per-group basis, the commands that are allowed.
Interoperability
Due to various interpretations of the RADIUS Request for Comments (RFCs), compliance with the RADIUS RFCs does not guarantee interoperability. Even though several vendors implement RADIUS clients, this does not mean they are interoperable. Cisco implements most RADIUS attributes and consistently adds more. If customers use only the standard RADIUS attributes in their servers, they can interoperate between several vendors as long as these vendors implement the same attributes. However, many vendors implement extensions that are proprietary attributes. If a customer uses one of these vendor-specific extended attributes, interoperability is not possible.
Traffic
Due to the previously cited differences between TACACS+ and RADIUS, the amount of traffic generated between the client and server differs. These examples illustrate the traffic between the client and server for TACACS+ and RADIUS when used for router management with authentication, exec authorization, command authorization (which RADIUS cannot do), exec accounting, and command accounting (which RADIUS cannot do).

Cisco ISE with Flex Connect ios 7.4

Hello my name is Ivan
I have a question:
Is possible to do a deployment with cisco ise (trust sec 2.0) and flex connect and web authentication to a cluster of cisco wlc (ios 7.4)?
There are a features or requeriments to configure this?
Regards
Ivan

By "cluster of cisco wlc" are you referring to the HA features for the 5508? HA or not should be irrelevant to the configuration of ISE w/ 7.4 WLC on flex connect.
Configuring CWA (central web auth) via L2/Mac-Filter and RADIUS NAC will require that you have a FlexConnect group built with the desired AP within the group. You will need to build FlexConnect ACLs and apply them to the FlexConnect group that correspond with the various NAC states the client will be in during the CWA process.
You will probably need 1 or 2 Web Policy ACLs
1. allow traffic to/from dns and ISE PSN
2. allow traffic to/from dns, ise and other resources (for instance for posturing/remediation)
Please note that you cannot "dynamically" assign ACLs to FlexConnect APs/Groups as part of the transition from central webauth reqd to RUN. The WebPolicies ACLs are the only ones that can override (think of them like pre-auth acls). Once you finally send back the access-accept for the client you can not apply dynamic acls to the particular wlan/vlan.
For instance if you needed differentiated access on a single network between guest and vendors, you couldn't send an access-accept back with an ACL for vendors vs an ACL for guests - in a FlexConnect environment. They would have to be placed on separate networks with their respective access.
It's possible this type of configuration (much desired) will be allowed in 7.5 whenever it rears its head.

Cisco ISE with multiple Network interface

Hello,
I am deploying Cisco ISE 1.2 in a distributed deployment and the requirement is to use external Radius proxy feature. ISE PSNs are designed to have 2 L3 NIC's, Eth0 for administration and Eth1 as client side facing NIC for Radius requests. I am interested to know would Cisco ISE in version 1.2 use Eth1 interface to send RADIUS authentication request to external RADIUS Proxy server.
Could not find above information in Cisco SNS-3400 Series Appliance Ports Reference.
http://www.cisco.com/en/US/docs/security/ise/1.2/installation_guide/ise_app_c-ports.html
Thanks
Kumar

Thanks Ahmad for the reply.
Cisco ISE uses standard RADIUS authentication and authorization port to send request to Exteranl RADIUS proxy. As per the interface/port refrence guide of version 1.2 this is listed that is causing a confusion :-
Eth0
Eth1
Eth2
Eth3
Policy Service node
Session
•UDP:1645, 1812 (RADIUS Authentication)
•UDP:1646, 1813 (RADIUS Accounting)
•UDP: 1700 (RADIUS change of authorization Send)
•UDP: 1700, 3799 (RADIUS change of authorization Listen/Relay)
External Identity Stores
and Resources
•TCP: 389, 3268, UDP: 389 (LDAP)
•TCP: 445 (SMB)
•TCP: 88, UDP: 88 (KDC)
•TCP: 464 (KPASS)
•UDP: 123 (NTP)
•TCP: 53, UDP: 53 (DNS)
(Admin user interface authentication and endpoint authentication)
In external Identity Stores and Resources it says Eth0 is used for (Admin user interface authentication and endpoint authentication), where under sessions it lists that all ports can be used for RADIUS Authentication and Authorization.
I am not sure what I am missing to understand between the two if you can highlight that.
Thanks
Kumar

Cisco ISE Vs Cisco Anyconnect Posture module with Advanced Endpoint Protection

We are planning to use cisco Anyconnect posture module with Adv Endpoint protection to examine the VPN users- This can check whether they a antivirus/anti spyware software installed on their work station and can force to update def file if its older than specified number of days, it can also check the firewall status on their workstation and enable if its not already.This can detect keylogger and emulation softwares also.
Do we get any additional advantages in using ISE compared to Anyconnect posture module ......
Siddhartha

These are good questions. We had them last year before we decided to purchase ISE, specifically for our VPN users.
I will be watching this thread to see what kind of responses you get.
As of right now, I can verify the ISE can indeed check if specific Anti-Virus is installed (i.e., your corporate AntiVirus), or if ANY (supported by Cisco within ISE) antivirus is installed, and it can force an update process for the AV if it detects that the DAT files are older than a admin specified amount of time.
Our issue at the moment (if you haven't searched the forums) is ISE detected the proper WSUS updates are indeed installed on the users systems and allowing the users system to talk to our internal WSUS server.
We are now wondering if the Advanced Endpoint licensing on the ASA would have been a better way to go.
Wishing you luck in finding your answers for us all.

Does Cisco ISE-3315-K9 with ise version: Service Engine: 1.0.4.573 support command accouting like ACS

Hi
Can Anybody can update whether ISE-3315-K9 with ise version: Service Engine: 1.0.4.573 , supports the command level accounting
Bascially , we have integrated Cisco Switches with Cisco ISE for Device Authentication using Radius , we are able get the authentication logs on to the devices , but for any command changes or update done on Cisco devices we are not able to get the command accounting ..
has succeed in command level accounting on Cisco ISE ..
Please update
Cisco ISE doesn't have TACACS feature ...

Command Accounting is a TACACS+ feature so not for ISE....yet.
However, you can do the following to send commands to syslog and not including passwords (hidekeys). I just picked 200 commands/lines to store in the local command buffer/log. increase or decrease as you have memory. The notify syslog is what sends it via syslog.
conf t
archive
log config
logging enable
logging size 200
hidekeys
notify syslog
end
wr mem
Remember, syslog is clear text :-) log away from user traffic when possible. Or use TLS based syslog when possible.
I hope you find this answer useful, if it was satisfactory for you, please mark the question as Answered.

Cisco ISE deployment with HP Swithes

Is there any compatibility matrix of cisco ISE with HP access swithes or there is any features restriction on HP access layer. The HP switches do support 802.1x.
Thanks
Qasim

Qasim,
The only compatibility with network access devices is all related to Cisco gear. It would be best to stick with a full supported solution for the sake of support. In my opinion this will be a nightmare to manage if an issue was to occur.

WLC RADIUS attribute with Cisco ISE

Hi All,
Does anyone get the same result as me when integrating Cisco ISE with Wireless LAN Controller ?
My Authentication Policy :
     Name: IsGuestAuthen
     IF "WLC_Authentication" THEN "Default Network Access" > "Internal Users"
My Authorization Policy :
     Name: IsGuestAuthen
     IF "Guest" THEN "InternetOnly"
When I monitoring on the Live Authentication page, I can see only the MAC address and a guest account that authenticated. I cannot see the IP address of the guest client. Do you get the same result as me ?
Please advise on how to get the IP address of the guest client to show on the Live Authentication Page.
Thanks,
Pongsatorn Maneesud

Exactly...here is the list of attributes sent in the access-request from the wlc -
http://www.cisco.com/en/US/docs/wireless/controller/7.2/configuration/guide/cg_security_sol.html#wp1992129
The framed ip address is sent in the accounting packet which doesnt appear in the live authentication report.
If you are up to speed on rest api's here is some reference material on this:
http://www.cisco.com/en/US/docs/security/ise/1.1/api_ref_guide/ise_api_ref_ch2.html#wp1089826
You can also run radius accounting report and filter it based off of account-start packets which will have the username and the ip address along with the mac address.

Cisco ISE and SecurID Integration Questions

I'm looking for some clarity trying to understand something conceptually. I want to integrate Cisco ISE with RSA SecurID, the idea being that if the user authenticates with RSA SecurID they end up on one VLAN, however, if they don't authenticate with (or don't use, or don't have) SecurID they'll end up on another VLAN. Note that I'm not using SecurID for wireless access...all PCs are wired to Ethernet.
We have been using RSA SecurID for a while and are currently on version 8.0. Our users are authenticating via the RSA Agent typically on Windows 8.1. Instead of the usual Windows login prompt, the RSA Agent first prompts for the username and passcode (they use an app on their smartphones to get the passcode), then after a moment or two, it prompts for their Windows domain password.
We have recently installed Cisco ISE version 1.3. With the help of a local Cisco engineer and going through the "Cisco Identity Services Engine User Guide", I have it set up and running along with a few 'test' ports on our Cisco 6809 switch, it basically works...as a test it's simply set up that if they authenticate they're on one VLAN, if not, they end up on another (this is currently without using RSA...just out-of-the-box Windows authentication).
The Cisco engineer was unable to help me with RSA SecurID, so pressing on without him, out of the same user guide I have followed the directions for "RSA Identity Sources" under the "Managing Users and External Identity Sources", and that went well as far as ISE is concerned; I am now ready to get serious about getting ISE and SecurID working together.
My mistake in this design so far was assuming that the RSA agent on the Windows client PCs would communicate with Cisco ISE...there doesn't seem to be a way to have them point to a non-RSA SecurID server for authentication. The concept I'm missing is what, or how, the end-user machine is supposed to authenticate taking advantage of both ISE and SecurID.
I have dug deeper into the Cisco ISE documentation but it seems heavily biased towards Wi-Fi and BYOD implementations and it's not clear to me what applies to wired vs wireless. Perhaps it's a case that I'm not seeing the forest for the trees, but I'm not understanding what the end-user authentication looks like. It apears that as I learn more about ISE, it should become the primary SSO source, that SecurID becomes just an identity source and the PC clients would no-longer directly communicate with the SecurID servers. That being the case, do I need to replace the SecurID client on the PCs and something else Cisco-ish fills this role? An agent for ISE? How do they continue to use their passcode without the RSA agent?
Thanks!

The external db not operation indicates that there is no communication between ACS and RSA. Did you fetch the package.cab file to analyse the auth.log file?
Have you already gone through the below listed link?
