ISE - NAC agent profile

Dears
I want to deploy NAC agent via GPO and I need to create agent profile , I know how to create it on ISE but how i get the file in xml format to be distributed ?

You can try installing only one PC (either by manual installation or by captive portal). If you have configured the posture rules in ISE then the NAC Agent automatically contacts the ISE server and downloads the last NACAgentcfg.xml available.
Then you could browse the following directory and find the NACAgentcfg.xml file in your PC.
C:\Program Files (x86)\Cisco\Cisco NAC Agent
After that you can mass deploy the NAC agent along with the xml file. Although is not mandatory to deploy the xml file because as a I said, every time there's a posture rule the NAC agent will download the last NACAgentcfg.xml available from ISE server.
Please rate if it helps.

Cisco ISE & NAC Agent in a Vmware View VDI Environment

Hi,
Anyone deployed Cisco ISE NAC agent on a vmware view virtual desktop environment (VDI)?

There are no known issues regarding VMWare view that would cause this.
For AV see -> http://www.novell.com/support/kb/doc.php?id=7007545
I find ProcMon for Sysinternals useful to see if other prcesses such as
AV are hitting those files unexpectedly. A few times I have seen AV
Exclusions not quite working as expected until tweaked.
The ZMD-Messages.log may show if the agent is doing something....

Cisco ISE NAC agent and Microsoft roaming profiles

Hi there,
I have installed Identity services engine version 1.1.3 in didstributed mode. The NAC agent is installed on the end user PC joined to the domain. when a user with a roaming profile logs into the PC, the NAC agent fails to run posture assesment, but if a user with non-roaming profile logs in, the NAC agent does posture and full network access is granted.
Is there something i need to do to enable the NAC agent to perform posture for users with a roaming profile.
Regards,
Henry

Hello,
I found the following from the cicso doc. Hope it helps!
The following failure scenarios might cause the Cisco NAC Agent to appear following successful user authentication when the client machine roams between CASs in Layer 3 (both In-Band and Out-of-Band) and Layer 2 /Layer 3 Out-of-Band environments. Erroneous Agent login dialogs could also appear if users roam from the Cisco NAC Appliance network in Layer 3 mode to a non-NAC network:
–ARP poisoning
–Temporary loss of network connection between the client machine and the CAS
–Access to untrusted interface IP address on the CAS from non-NAC network segments on NAC-enabled client machines
Cisco offers the following recommendations to prevent this situation:
–Ensure all trusted networks (post-authentication) can reach the CAS untrusted interface IP address through the CAS trusted interface only
–Block discovery packets from all non-NAC networks to the CAS untrusted interface IP address (discovery packets that arrive on the trusted interface of the CAS are blocked by default)
For more information please refer to the following link:

ISE nac Agent automatic upgrade possible ?

Hello all,
I have this :
802.1x windows with NacAgent version (let's say 1) <----> 802.1x Enabled Switch (aaa radius OK) <------> ISE and AD on the same LAN
ISE is configured for client provisionning with material (NacAgent version 2) downloaded from Cisco website (as depicted in the documentation)
I've a basic authentication and authorization scheme that let me in properly but I expect the NACAgent to be upgraded.
No profiling is configured for the time being.
Is anybody can help ?
Best regards ?

Hi Tarik,
Your are right regarding that option "upgrade is mandatory"
However, my case was that you do need to enter the ISE's FQDN on the NAC Client and make sure that DNS operates properly.
Once authenticated, the NAC agent shows an upgrade message.
It works.
Thank you all.

ISE nac agent provisioning question

I have downloaded the nac agents and compliancy modules to the ISE, and configured the client provisioning rules. The user guide doesn't really explain the next steps very good.
I guess because User Identity Groups are used in the policy, the provisioning is used with webauth, is that correct?

Jeppe,
The client provisioning is done with any authentication method. Either via dot1x or webauth, it is the authorization policy that starts this process. You redirect your clients the client provisioning portal using the authorization policy. Then you determine which agent (web agent, nac agent, or no agent) via the client provisioning policy.
Hope that helps,
Tarik Admani

Cisco ISE NAC Agent RDP session

Is there a way to get the NAC Agent to run when a user logs on a Windows machine in a RDP session?

You have to go and check the dACL that is part of authorization profile, you will find that it is blocking your RDP access as when you do a remote desktop your authentication token is host/machine-name.domain. Now, the easiest FIX to permit RDP traffic is to modify the dACL but this won't solve your problem. Why? Because now your dACL will allow you do a remote desktop now BUT it will block rest of your communication.
So either you permit all as soon as your machine is authenticated or you will continue to face this issue.

Custormizing the NAC agent profile

Hi,
We need to have very minimal user intervention while doing the completing the posture part on NAC agent on user PC.
Can someone please advise how to achieve the below task.
1) Automatically accept the Network usage policy before its timeout (50 sec) expired (if the timeout expired it will go to "Deny Network Access" state as it assume that clicking "Reject" button (attached screen1)
2) we need to keep all the posture pop-up, verification timings.
Thanks

Hi,
Currently this isn't possible. If you have an account team, please ping them to get this added to the feature request list.

MAC OS X unable to download Cisco ISE supplicant agent

Hi,
I have a problem with MAC OS X clients unable to download the Cisco ISE supplicant agent using Safari browser but able to login on the ISE guest portal. If the same client was to login to the ISE guest portal using Firefox; it has no issues downloading the ise supplicant and posture agent.
I have tried to update the Java version on the client to the latest; however it does not resolve the issue. As I am new to MAC OS clients; I was wondering what may be the cause of the issue?
I have summarized the issue as follows:
1. MAC OS X 10.8 with safari 6 -- unable to download agent but can login successfully on the Cisco ISE guest portal
2. MAC OS X 10.8 with Firefox -- able to login to Cisco ISE guest portal and download agents; no issues
3. MAC OS X 10.7 with safari and firefox --- unable to download agent but can login successfully on the Cisco ISE guest portal
4. Windows XP & Windows 7 & Iphone/Ipad/Android -- able to login/download agent without any issues
Any suggestions is appreciated.
Thanks.

For Agent Download Issues on Client Machine
• Ensure that a client provisioning policy exists in Cisco ISE. If yes, verify the
policy identity group, conditions, and type of agent(s) defined in the policy.
(Also ensure whether or not there is any agent profile configured under Policy >
Policy Elements > Results > Client Provisioning > Resources > Add > ISE
Posture Agent Profile, even a profile with all default values.)
• Try reauthenticating the client machine by bouncing the port on the access
switch.
Remember that the client provisioning agent installer download requires the following:
• The user must allow the ActiveX installer in the browser session the first time an agent is installed
on the client machine. (The client provisioning download page prompts for this.)
• The client machine must have Internet access.

NAC Agent Login Dialog Not Appearing - ISE 1.1.1 issue ?

Agent Fails to Initiate Posture Assessment
The NAC agent is properly installed on a Windoes 7 , IE 9 machine, the certificates from ISE ADM PRI are installed in trustable certificate store in the client machine but is a selfsigned ISE certificate.
The reports / USER / Profiling report says the Provisioning Agent has completed the assessment ok.
The redirected URL is working fine (SEE Evidence)
We are always prompted to install the NAC agent again or looking at the additional prompted information wait for the NAC agent to load and complete.
The operations status remains with postering status pending forever and nothing else happens.
Symptoms or Issue
The agent login dialog box does not appear to the user following client provisioning.
Conditions Cisco Says this issue can generally take place during the posture assessment phase of any user
authentication session.
Cisco Advises as Possible Causes There are multiple possible causes for this type of issue. See the following
Resolution descriptions for details of what was already tested by us and please see the atached files for your switch configuration and evidences. .
CISCO SUGGESTED POSSIBLE CAUSES AND RESOLUTIONS
Resolution • Ensure that the agent is running on the client machine. ALL TESTED OK
• Ensure that the Cisco IOS release on the switch is equal to or more recent than
Cisco IOS Release 12.2.(53)SE. - OK
• Ensure that the discovery host address on the Cisco NAC agent or Mac OS X
agent is pointing to the Cisco ISE FQDN. (Right-click on the NAC agent icon,
choose Properties, and check the discovery host.) - OK (See evidence)
• Ensure that the access switch allows Swiss communication between Cisco ISE
and the end client machine. Limited access ACL applied for the session should
allow Swiss ports: ALL CONFIGURED as CISCO GUIDELINES OK (SEE EVIDENCE)
• If the agent login dialog still does not appear, it could be a certificate issue.
Ensure that the certificate that is used for Swiss communication on the end client
is in the Cisco ISE certificate trusted list. (ALL CHECKED OK SEE EVIDENCE)
• Ensure that the default gateway is reachable from the client machine. (TESTED OK)

Hi.
Can you paste all the ACLs on your switch especially the webauth redirect ACL which should deny traffic towards the PSN.

Zubair

Is it possible to run Posture using ISE 1.2 without NAC Agent provisioning?

Is it possible to run Posture using ISE 1.2 without NAC Agent provisioning?
-My customer does not want to push NAC Agent installation on BYOD type of computers (non-managed by the company computers).
-The requirement is to check for posture only company owned wired, wireless, and VPN connected Windows computers. The rest of the endpoints should be considered as posture incompliant, and limited access to the network should be allowed.
-No certificates are used.
-I’ve configured the required posture check, and it all works fine if a PC has NAC Agent manually installed (without ISE Client Provisioning). However, when I use a PC without NAC Agent, it is redirected to Client Provisioning Portal and is stuck there as Client Provisioning is deliberately not configured in ISE.
-If I remove Posture Remediation Authorization Profile that does URL redirect, the posture does not work.
-For now I'm testing it on wired endpoints.
Is there a way to configure ISE to fulfill the listed above requirements?
Any ideas would be appreciated.
Thanks,
Val Rodionov

Everyone who finds reads this article,
I'm answering my own quesiton "Is it possible to run Posture using ISE 1.2 without NAC Agent provisioning?"
The answer is Yes.
After doing research and configuration testing I came up with a solution, and it works fine for wired and VPN connections. I expect it to work on wireless endpoints as well.
ISE configuration:
Posture General Settings - Default Posture Status = NonCompliant
Client Provisioning Policy - no rules defined
Posture Policy - configured per requirements
Client Provisioning (under Administration > Settings) - Enable Provisioning = Enable (it was disabled in my first test)
Authorization Policies configured as regular posture policies
The result:
After successful dot1x authentication posture redirect happens. If the PC does not have NAC Agent preinstalled, the browser is redirected to Client Provisioning Portal and a default ISE message is displayed (ISE is not able to apply and access policy... wait one minute and try to connect again...). At the same time, the endpoint is assigned NonCompliant posture status and proper authorization policy is applied. This is what I wanted to achieve.
If NAC Agent was preinstalled on the PC, after successful dot1x authentication the NAC Agent pops up and performs posture check. If posture is successful, posture compliant authorization policy is applied. If posture check fails, NonCompliant posture status is assigned and posture non-compliant authorization policy is applied. Which is the expected and needed result.
The only part that is not perfect it the message displayed to the end-user when posture is about to fail. I did not find a place to change the text of that message. I might need to open TAC case, so this file can be manually found and edited from CLI (root access).
Best,
Val Rodionov

NAC Agent 4.9 issue while remediation with in ISE

We are installed NAC agent 4.9 where we have configured posture policy for Symantec Endpoint Protection version 11x in ISE 1.1.1. Where when enduser fallen down to remediation and try to remediate to collect the latest anti virus definitions from Local Antivirus, when clicking on the update button we get a message stating
"The Remediation you are attempting is reporting an access denied error. This is usually due to a privileg issue. Please contact your system
administrator"
It continuosly asking that prompt and giving that priviligae message.
Are we need to have administrator rights for remediation ? and this prompt is appearing again and again till the remediation timer and then it fallen down to Non-compliant (Restricted ) profile.
Please find attached screen shots for the same

I figured out a solution that works you must disable Online Certificate Status Protocol (OCSP) on the affected system. To do this :
    Open Keychain Access. Keychain Access can be found by selecting Go in the Finder and choosing the Utilities option. Keychain access should be listed in the folder that appears. Double-click the Keychain Access icon to open it.
    Select Keychain Access -> Preferences from the menu at the top of the screen
    Choose the Certificates tab
    Change the OCSP option from Best Effort to Off
    Close the Preferences dialog and quit Keychain Access
    You should be able to NAC now

ISE 1.2 nac agent provision

Hi,
Is there any way to do a nac agent auto provision?
I know it can be achieve by cwa portal(web redirect) and user have to install nac agent manually. But we would like to see nac agent be installed right afeter user successfully login using 802.1x.

I dont follow your thought process but this is how i have most of my deployments are setup.
CWA < NSP < COA < 802.1x < Posture Status Unknown *In this state either client does or doesnt have nac agent in which ISE will proceed to install it or continue probing to for the NAC agent.
Remove CWA < NSP < COA from the picture and you have your exact scenario. What is your work flow look like that it is not "automatic" and define what you mean by "manually"?

NAC Agent and NSP provisioning with ISE 1.1.1

I am trying to get all workstations (OSX and Windows) to install both the Native Supplicant Wizard and NAC Agent during the On-boarding process.
I am currently using the default guest portal in ISE.
The environment has been setup using a Dual SSID design.
At the moment, devices can connect to the provisioning SSID and get CWA. Device registration works, the portal runs the NSP setup which correctly sets up the network adapter.
The problem is the portal never attempts to install the NAC Agent.
The client provisioning policy has a separate policies for wireless/wired as well as OS. Each policy applies both a NSP and NAC Agent configuration. It appears the guest portal only checks the NSP configuration and not the NAC Agent config.
Any ideas?

Just so i understand this correctly you are using both a client provisioning portal and a native supplicant provisoning portal tied into seperate authz policies.
With that out of the way are you checking to see if the client is compliant in the client provisioning portal policy.
Let me know if you have the following configured (example windows OS), this is assuming that the endpoint is statically assigned to RegisteredDevices after native suppliant provisioning.
Rule 0 (endpoint group = RegisteredDevice) AND (AD:Domain user and authentication method:x509 and posturestatus:COMPLIANT) = Permit Access
Rule 1 (endpoint group = RegisteredDevice) AND (AD:domain user AND authentication method:x509[if you deployed certs in the native supp condition] AND workstation NOT EQUAL:COMPLIANT) RESULT client provisioning portal.
Rule 2 (endpoint group = Workstation) AND (AD:Domain User AND authentication mehod using mschapv2) RESULT windows provisioning portal
Hope that helps,

ISE and NAC Agent

Hello, we currently run NAC for our wired (OOB), wireless (IB) and VPN (IB) enviroments. We are looking at migrating over to ISE for our wireless enviroment as a first step, with follow-up projects to move the VPN and wired clients over. I have been reading that ISE will still use the NAC agent. Our current NAC enviroment is at 4.7.2 and we are running the 4.7.2.10 agent. We do not want to upgrade this enviroment, we would rather focus on migrating to ISE. So our thought was to upgrade the clients to the latest NAC agent version 4.9.1.5. This agent is supported against the 4.7.2 NAC Manager. The problem is, I do not see this agent version listed as supported in the ISE compatibility matrix. Instead, they list a NAC agent of 4.9.0.37, which ironically, is NOT listed in the NAC compatiblity matrix. So what version of NAC agent should we run in a mixed enviroment? I am hoping 4.9.1.5 is supported against ISE, and the matrix is simply not updated yet. Thank you in advance for your help.

Not sure I understand. The 4.9.1.5 NAC agent does run against our CAM, as we have tested that and it is listed in the support matrix. So if we upgrade our NAC applainces, we would still run that agent. Does that agent tun against ISE, and if not, what is Cisco's recommendation to bring ISE into the enviroment? We have to have a migration path, and wireless seemed like a logical first step. But we need a NAC agent that will work against Clean Access AND ISE as our laptops will be wireless and wired at different times. Which Agent would be recommended?

Determining which NAC Agent to use for ISE

We are planning an upgrade to our ISE environment from 1.1.4 to 1.2. I have downloaded the agent that is recommended for 1.2 (NAC Agent 4.9.4.3) to begin testing with it. Unfortunately the first test I run is using that client against our ISE 1.1.4 servers. It doesn't work! It runs sporadically at best, taking up to 3 minutes to pop up and posture the system. Other times, I give up, after 20 minutes of waiting, and it never runs. This is quite a spot, I do not want to upgrade the ISE system to 1.2, then run into an issue and have to mass upgrade over 2000 clients all at once to get them running. My hope was to upgrade to the NAC Agent prior to the ISE upgrade but unfortunately that has been short circuited.
So my question is, has anyone run ISE 1.2 with NAC Agent 4.9.1.6? That is what we are currently using, as it runs well against both ISE 1.1.4, and NAC 4.9.1 (which is still used for our wired environment). We need to find an agent we can use to bridge us from the time we upgrade ISE to 1.2, and the time we bring our wired environment into the ISE fold and remove NAC appliance. I should note, ironically, that 4.9.4.3 NAC Agent runs flawlessly against the NAC 4.9.1 appliance. The issue is running that NAC Agent against ISE 1.1.4. That is ecactly the opposite of what I would have guessed! Please help!
Jeff

Yes sir, I am aware of that recommendation, however once I downloaded and started testing several clients with that version, none of them run well, if at all, against 1.1.4 which is the current production version we run in our environment. So I would have to either upgrade all 2000 clients immediately after we upgrade or ISE system to 1.2, or take a chance that our current agent (4.9.1.6) will run against ISE 1.2. I was hoping to find a recommendation of an agent version that runs well against both ISE 1.1.4 and ISE 1.2 so we could upgrade the clients at a controlled rate prior to upgrading ISE to 1.2
