ISE 802.1x EAP-TLS machine and smart card authentication

I suspect I know the answer to this, but thought that I would throw it out there anway...
With Cisco ISE 1.2 is it possible to enable 802.1x machine AND user smart card authentication simultaneously for wired/wireless clients (specifically Windows 7/8, but Linux or OSX would also be good). I can find plenty of information regarding 802.1x machine authentication (EAP-TLS) and user password authentication (PEAP), but none about dual EAP-TLS authentication using certificates for machines and users at the same time. I think I can figure out how to configure such a policy in ISE, but options seem to be lacking on the client end. For example, the Windows 7 supplicant seems only able to present either a machine or user smart card certificate, not one then the other. Plus, I am not sure how the client would know which certificate to present, or if the type can be specified from the authenticator.

Hope this video link will help you

802.1x eap-tls machine + user authentication (wired)

Hi everybody,
right now we try to authenticate the machines and users which are plugged to our switches over 802.1X eap-tls. Works just fine with windows.
You plug a windows laptop to a switchport and machine authenticates over eap-tls with computer certificate. Now the user logsin and our RADIUS (Cisco ACS) authenticates the user as well, with the user certificate. After eap-tls user-authentication the RADIUS checks if the workstation on which the user is currently logged in is authenticated as well. If yes = success, if no the switchport will not allow any traffic.
Now we have to implement the same befaviour on our MacBooks Pro. Here the problems start. First of all I installed user and computer certificates issued by our CA (Win 2008 R2). So far so good. Now I have no idea how to implement the same chain of authentication. I was reading countless blogs, discussions, documentations etc. about how to create .mobileconfig profiles. Right now im able to authenticate the machine, and _only_ if I login. As soon as I logout eap-tls stops to work. It seems that loginwindow does not know how to authenticate.
1) how do I tell Mavericks to authenticate with computer certificate while no user is loged in ? already tried profiles with
<key>SetupModes</key>
<array>
    <string>System</string>
    <string>Loginwindow</string>
</array>
<key>PayloadScope</key>
    <string>System</string>
but it does not work
2) How do I tell Mavericks to reauthenticate with user certificate when user logs in ?
Thanks

Unfortunatelly this documents do not describe how to do what I want.
I already have an working 802.1x. But the mac only authenticates when the user is loged in. I have to say that even this does not work like it should. If Im loged in sometimes i need to click on "Connect" under networksettings and sometimes it connects just automatically. Thats really strange.
I set the eapolclient to debugging mode and see following in /var/log/system.log when I logout.
Feb 20 18:39:09 MacBook-Pro.local eapolclient[734]: [eaptls_plugin.c:189] eaptls_start(): failed to find client cert/identity, paramErr (-50)
Feb 20 18:39:09 MacBook-Pro.local eapolclient[734]: en0 EAP-TLS: authentication failed with status 1001
Feb 20 18:39:22 MacBook-Pro.local eapolclient[734]: [eaptls_plugin.c:189] eaptls_start(): failed to find client cert/identity, paramErr (-50)
Feb 20 18:39:22 MacBook-Pro.local eapolclient[734]: en0 EAP-TLS: authentication failed with status 1001
this are only debugging messages I get. Looks to me like eapolclient is not able to find a certificate (?)
The certificates are in my System keychain.
Unfortunatelly apple also changed the loging behaviour of eapolclient, I dont see any eapolclient.*.log under /var/log
Any ideas ?

Cisco ISE: 802.1x [EAP-TLS] + List of Applicable Hot-Fixes

Dear Folks,
Kindly suggest the list of all possible Hot-Fixes required for the Cisco ISE EAP-TLS solution... We have applied 9 HotFixes so far. But, still the connectivity is intermittent. Is there any list for all applicable Hot-Fixes?
OS = Win 7 SP1 (32/64 Bit) and Win 8
Thanks,

Hi Mubasher
KB2481614:      If you’re configuring your 802.1x settings via Group Policy you’ll see      sometimes EAP-PEAP request from clients in your radius server log during      booting even if you’ll set EAP-TLS. This error happened in our case with      1/3 of the boots with some models. The error is caused by a timing problem      during startup. Sometimes the 802.1x is faster and sometimes the Group      Policy is, and if the 802.1x is faster than the default configuration is      taken, which is PEAP. Which lead to a EAP-NAK by the radius server.
KB980295:      If an initial 802.1x authentication is passed, but a re-authentication      fails, Windows 7 will ignore all later 802.1x requests. This hotfix should      also fix a problem with computers waking up from sleep or hibernation –      but we’ve disabled these features so I can’t comment on them.
KB976373:      This hotfix is called “A computer that is connected to an IEEE      802.1x-authenticated network via another 802.1x enabled device does not      connect to the correct network”. I can’t comment on this, as we’ve not      deployed 802.1x for our VoIP phones at this point.I would guess it is the      same for Windows 7 too. The linked article tells you to install the patch      and set some registry key to lower the value.
KB2769121:      A short time ago I found this one: “802.1X authentication fails on a      Windows 7-based or Windows 2008 R2-based computer that has multiple      certificates”. At time of writing I’m not sure if it helps for something      in my setup. According to the symptoms list of the hotfix, it does not,      but maybe it helps for something else, as the one before does.
KB2736878:      An other error during booting – this time it happens if the read process      starts before the network adapter is initialized. Really seems that they      wanted to get faster boot times, no matter the costs.
KB2494172:      This hotfix fixes a problem if you’ve installed a valid and invalid      certificate for 802.1x authentication. The workaround is just deleting the      invalid certificate. I’m not sure at this point if it affects also wired      authentication.
KB976210:This      problem occurs only during automated build processes and if you use an EAP      method which needs user interaction – as I don’t do that I can’t comment      on this hotfix.

EAP-TLS machine and user cert or both

If I use machine and user certificates does that mean the machine get's an IP address, authenticates, the user then logs on which causes another DHCP renew and user authentication? Is it better to use machine and user or just machine?

It depends on your needs and applications, the advantage of also using machine authentication is that the machine connects, authenticates and is on the wireless network irrelevant of whether a user has logged in, which means you can remote access or monitor the machine at that point. I know alot of facilities that do it that way because they manage the machines with things like SMS, etc.. Without machine authentication the computer won't attach to the wireless until a user physically logs into the machine at which point it pass authentication.
personally I like the machine authentication that way you can push updates and other things to the machines without having to either send a person to the machine to login or waiting for a user to login so that you can access the machine, it just needs to be on.
in short machine authentication replicates being hardwired to the network.
Hope this helps... please rate useful posts.

Cisco ISE for 802.1x (EAP-TLS)

I work for a banking organization and security is an area that needs to be improved continuously. I am planning on implementing Cisco ISE for 802.1x together with a Microsoft PKI for certificate issuing and signing.
I am currently trying to implement this in our test environment and I have managed to do a few basic bootstrapping tasks. I need someone to push me into the right direction as to how I can achieve what i am seeking.
I will use Cisco 2900 series switches on the access layer and a few HP switches as well which supports 802.1x.
I want to configure the ISE to process authentication requests using 802.1x EAP-TLS (Certificate Based). All the workstations on the domain needs to authenticate itself using the certificates issued to it by the Certificate Issuing Authority.
I have already managed to get the PKI working and have rolled out the certificates on all the workstations on the test environment. I can't seem to configure the Authentication portion on the ISE.
I request if someone can guide me or direct me to materials that can help achieve the above requirements. The guides available on the Cisco website are overwhelming and I can't seem to figure out how I am supposed to configure the authentication portion.
My email: [email protected]
Cheers,
Krishil Reddy

Hello Mubashir,
Many timers can be modified as needed in a deployment. Unless you are experiencing a specific problem where adjusting the timer may correct unwanted behavior, it is recommended to leave all timers at their default values except for the 802.1X transmit timer (tx-period).
The tx-period timer defaults to a value of 30 seconds. Leaving this value at 30 seconds provides a default wait of 90 seconds (3 x tx-period) before a switchport will begin the next method of authentication, and begin the MAB process for non-authenticating devices.
Based on numerous deployments, the best-practice recommendation is to set the tx-period value to 10 seconds to provide the optimal time for MAB devices. Setting the value below 10 seconds may result in the port moving to MAC authentication bypass too quickly.
Configure the tx-period timer.

Connecting iPads to an Enterprise Wireless 802.1x (EAP-TLS) Network Using Windows Server 2003 IAS

Hi there,
I am asked to deploy iPads on an 802.1x EAP-TLS WiFi network. The customer has a Windows Server 2003 IAS server providing RADIUS. There also is a Windows based CA infrastructure in place. This solution is in production and is already being used by other wireless devices. Could someone please highlight the configuration steps for the iPad deployment? The customer whishes to automate the initial deployment and the renewal of the certificates. I have a basic understanding of 802.1x, RADIUS, Certificates etc. in a Windows infrastructure but I am new to enterprise deployment of iPads. There is no MDM tool in place by the way...
I did find a Microsoft article which I think describes what needs to be done: http://blogs.technet.com/b/pki/archive/2012/02/27/ndes-and-ipads.aspx. This article basically states the following steps:
1. Create a placeholder computer account in Active Directory Domain Services (AD DS)
2. Configure a Service Principal Name (SPN) for the new computer object.
3. Enroll a computer certificate passing the FQDN of the placeholder computer object as a Subject Name, using Web Enrollment Pages or Certificates MMC snap-in directly from the computer (Skip step 4 if you are using the Certificates MMC snap-in)
4. Export the certificate created for the non-domain joined machine and install it.
5. Associate the newly created certificate to the placeholder AD DS domain computer account manually created through Name Mappings
The article then elaborates on specific steps needed for the iPad because it treats all certificates as user certificates. Can someone confirm this behavior??
Regards,
Jeffrey

Use VPP. Select an MDM. Read the google doc below.

802.1x EAP-TLS for wired users with ACS 5.5

Hi All,
We are configuring a new setup for wired users authentication with 802.1x(EAP-TLS). ACS 5.5 we are using as authentication server.
We have added the root CA(internal) certificate and certifcate for ACS signed by CA. Now We want to check the authentication is working or not . I hope both root CA and identity certifcate also we need to install in the laptops. But I am not sure how to download the certifcates for client machine manually from CA.
Kindly suggest on how to get certificates for clients both manually as well as automatically?
Thanks,
Vijay

Hi Vijay,
for the Wired 802.1x (EAP-TLS) you need to have following certificates:
On ACS--- Root CA, Intermediate CA, Server Certificate
On Client-- Root CA, Intermediate CA, User certificate(In case of user authentication) OR Machine certificae(In case of Machine authentication)
I am not sure which third party certificate are you using, If its in house Microsoft or any other certificate server then you need download the client certificate from the server itself.
In case of Microsoft, There will be a template for user certificate. You can select it and create user certificate
This one is an old document, But has steps to configure Machine certificate for the user, You can see the steps to download user certificate if its Microsoft server:
http://www.cisco.com/c/en/us/support/docs/security/secure-access-control-server-windows/43722-acs-eap.html#wc-2
In case You are using the third party certificate serevr , Then you need to check with them on how to download the user certificate

ACS 5.3, EAP-TLS Machine Authentication with Active Directory

I have ACS 5.3. I am testing EAP-TLS Machine Authentication using Active Directory as an external Identity Store. II was testing and everything was going fine until I did some failure testing.
My problem: I deleted my computer account out of Active Directory and tried to authenticate my wireless laptop and it still worked when it should have failed.
Here is some of the output of the ACS log. You can see that the computer could not be found in AD and this was returned to the ACS. However, ACS still went ahead and authenticated the computer successfully.
Evaluating Identity Policy
15006 Matched Default Rule
22037 Authentication Passed
22023 Proceed to attribute retrieval
24433 Looking up machine/host in Active Directory - LAB-PC-PB.VITS.attcst.sbc.com
24437 Machine not found in Active Directory
22016 Identity sequence completed iterating the IDStores
Evaluating Group Mapping Policy
12506 EAP-TLS authentication succeeded
11503 Prepared EAP-Success
Evaluating Exception Authorization Policy
15042 No rule was matched
Evaluating Authorization Policy
15006 Matched Default Rule
15016 Selected Authorization Profile - Permit Access
22065 Max sessions policy passed
22064 New accounting session created in Session cache
11002 Returned RADIUS Access-Accept
I was assuming that if the computer was not found, the Identity Policy would fail, so I did not configure any authorization policy. Do I need an authorization policy to tell the ACS to fail the authentication if the machine cannot be found in AD? If I need an authorization policy, how do I configure it?
Note: In my Identity Store Sequence, I did enable the option:
For Attribute Retrieval only:
If internal user/host not found or disabled then exit sequence and treat as "User Not Found"
but this only seems to work for internal identity stores (at least based on my testing)
Under my Access Policy Identity tab, I configured the following Advanced features:
Advanced Options
If authentication failed
RejectDropContinue
If user not found
RejectDropContinue
If process failed
RejectDropContinue
And that didn't do anything either.
Any ideas? Thanks in advance.

Can try the following. Define an attribute to be retrieved from Active Directory and that exists for all objects. When defining the attribute it can be given a default value. Assign a default value which is a value that will never be returned for a real machine entry (eg "DEFAULTVALUE") and give it a "Policy Condition Name"
Then can make a rule in the authorization policy such as
If "Policy Condition Name" equals "DEFAULTVALUE" then "DenyAccess"

802.1x EAP-TLS with Cisco IP-Phone on MS NPS

Hi,
does anybody get 802.1x - EAP-TLS with IP-Phones ( e.g. 7962G ) on Microsoft NPS up and running?
With ACS it is not a problem at all.
thx
Sebastian

Hi all !
Have you solved this problem (LSC certificate )? I am facing the same problem and I did not find the solution yet.
This is the last e-mail that Microsoft TAC has sent to the customer:
====================================================================================
As per the discussion, we need to engage Vendor on the case to find out why the CRL Distribution Point (CDP) and AIA paths are missing from the certificate. Ideally CDP contains that Revocation List of the certificates and AIA is used for building the certificate chain.
"Please find below some more information about the same from Microsoft TechNet Article :
CRL Distribution Points : This extension contains one or more URLs where the issuing CA’s base certificate revocation list (CRL) is published. If revocation checking is enabled, an application will use the URL to retrieve an updated version of the CRL. URLs can use HTTP, LDAP or File.
Authority Information Access : This extension contains one or more URLs where the issuing CA’s certificate is published. An application uses the URL when building a certificate chain to retrieve the CA certificate if it does not exist in the application’s certificate cache."
=====================================================================================
Tks for your help !!!!!!!

802.1x/EAP-TLS Fragmentation across VPN tunnel

I am having an issue authenticating users via 802.1x/EAP-TLS across an IPSec tunnel. I am using route-based VPN with SVTI configuration on a 2921 and 1941. I have the following settings defined:
- Under the tunnel interfaces:
- MTU 1390
- MSS 1350
- PMTUD
- Under the ingress LAN interface
- route-map to set the DNF bit to 0
- On the RADIUS Server (2008 NPS)
- Framed-MTU: 1300
This had been working for months until I got a call last week about users not being able to authenticate to our secured SSID. I fired up wireshark and also used my client monitor tool in my wireless NMS to watch what is going on. I see all of the access-request and access-challenge exchanges, but the final exchange never happens. In both captures you can see messages with id's 77-81, but message id 82 isn't shown in the wireshark capture, only fragments are. In the client monitor capture you can see that message id 82 is 1726 bytes in length. Now, if I capture packets on my local LAN, the 1726 byte packet is properly fragmented and users can authenticate just fine.
What am I missing with this?? I have scoured the Internet trying to find a setting that I must have missed, but I can't. I've tried adjusting the Framed-MTU, all the way down to 1100.
Thanks for you help.

I figured I would post back with my results. I ended up removing my mtu value from the tunnel interfaces and then fired up wireshark again. This time I found a crap load of ICMP time-exceeded messages which told me that PMTUD is not working properly across the tunnel. From there I simply re-applied my previous MTU numbers back into the tunnel configs and all of the sudden EAP-TLS started flowing fine. I do not know why removing and re-applying the MTU would make things start working again so I assume that I'll be dealing with this again sometime in the future.

EAP-TLS machine authentication problems

Well..
I have the following devices:
WCS
Wlan controller 4402
AP 1130 LWAPP
Workstation XP sp2
Secure ACS 4.0
Windows CA
Windows AD
Everything else is working properly, except EAP-TLS. Server certificate is installed in ACS and trust list is OK. Client certificate is installed in workstation machine store. PEAP-MsCHAPv2 working OK, ACS logging prompts successful authentication. I tried to use the certificate authentication from windows wlan properties, but the log was still empty.
Which clarifications do I have to do in ACS and AD?
Can someone help me and give me very detailed instructions on how to make it work.

Hi,
We had a same problem until we ran 2 windows hotfixs. Those are: WindowsXP-KB893357-v2-x86-ENU.exe and WindowsXP-KB890046-x86-ENU.exe Have you tried to do this. Our EAP-TLS machine authentication is working fine now.
Have you enabled EAP-TLS authentication in ACS? ACS-> System configuration: Mark Allow EAP-TLS

TACACS+ and Smart Card login

We are currently using Cisco ACS 5.3 integrated with Active Directory for authentication to our Cisco devices. We are looking to move to smart card logins and trying to find out if this is possible to authenticate to the console/ssh on the router/switch using a smart card.

Direct Smart card authentication is not supported for vty / console session on IOS. However, via TACACS to a AAA server (e.g. Cisco ACS) you can turn it to use a two factor-based external authentication store. Even if the Smart card get the PKI cert of some kind to the client PC and then to the terminal emulator like Putty or SecureCRT, AAA with Tacacs + would not be possible as Tacacs is not capable for encapsulating any kind of PKI.

Token and smart card reader are not detected on Mavericks if not plugged on a USB port during system boot

Well, both token and smart card reader are not detected on OS X 10.9 if not plugged on a USB port during system boot. So, if I am already working within the system and need to use my certificates I have to plug the token or smart card reader on a USB port and restart Mavericks.
Token is a GD Starsign and Smart Card Reader is a SCR3310 v2.
Thoughts?

SCS is a very good app, since I've read that Apple has discontinued support for PC/SC interfaces after the release of Mountain Lion.
(My previous installation was a Mavericks upgrade from Lion)
However, I don't know what and how to debug using Smart Card Services. Do you know any commands to use?
Apparently, the SC reader reports no issues: the LED is blinking blue when no smart card is present and becomes fixed blue when a smart card is inserted – according to the manuals, this shows that there is correct communication between the OS and the CCID reader.
I don't know what to do; I'm beginning to hypothesize it's a digital signer issue. In fact, my smart card only supports one application called File Protector (by Actalis) to officially sign digital documents. This application seems to have major difficulties in identifying the miniLector EVO.
The generic and ambiguous internal error comes when I try to manually identify the peripheral.
Athena CNS is one of the Italian smart cards and is automatically recognized and configured (so it's correct – no doubts about this), while "ACS ACR 38U-CCID 00 00" seems to be the real name of the miniLector.
(I'm assuming this because System Information also returns that the real manufacturer is ACS... bit4id is a re-brander)
However, when I click on it and then tap OK, it returns internal error.
As first attempt, I would try to completely erase&clean File Protector files to try a reinstall. Then, if this still doesn't work, I'd debug using the terminal.
So:
- Do you know any applications to 100% clean files created by an installer?
- Do you have in mind any solutions that I might have forgotten?
Thanks in advance from an OS X fan!

ACS with CAC/Smart Card Authentication

I have configured ACS 5.1 to authenticate a wireless user via EAP-TLS using the predefined Certificate Authentication Profile within ACS, but I don't understand how it is successfuly authenticating users. Is it simply trusting any user that presents a certificate signed by the root certificate I imported into the ACS certificate authority?
Thanks.

Smart card authentication for IOS device

I am just wondering if anyone was able to successfully implement smart card authentication for vty and console session. if anyone did, can you please point me to the documentation and the implementation guide? thanks

Actually, with the rsa key pair setup in ISO 15+, you can use a smart card to authenticate to cisco switches. I'm still working out all the details but you would need SecureCRT or Putty-CAC. SecureCRT allows you to export the public key from a pki cert and then import that into the switch/router. The disadvantage is you can only use the first cert in the list. Putty-CAC allows you to select which PKI cert you want to use but I haven't verified you can export the public key from a cert. If you contact me, I'll email you the info need to use use SecureCRT.
