ISE using Azure MFA and AD

Are there any white papers on configuration VPN Authorization in ISE using Azure MFA and AD?

Re: ISE using Azure MFA and AD

Hi,

You can find information on ISE and Anyconnect design guides.

ISE Design & Integration Guides

With related to MFA, ISE support RSA secure ID, Radius token. You can also use an external server such as Symatec VIP with guest portal. You can look at the integration with Symantec for that from the design guide above.

ISE is supporting Azure AD with MFA for SAML 2.0 SSO at ISE end-user-facing webauth portals if the primary auth is form-auth authentication.

Now, ASA supports MFA with two different identity sources for authentication, you can use ISE as authorization only in such cases.

Thanks

Re: ISE using Azure MFA and AD

if nothing for MFA how about whitepaper about using ISE for Anyconnect VPN authentication without MFA?

Re: ISE using Azure MFA and AD

Hi imsheikh,


I was working on the same thing it looks like you are trying to do.  We just set up an Azure MFA server to set up multi-factor for VPN and I also found that it works quite nice with accessing network devices.  Since the MFA server is on-prem and uses our AD I used the Azure server as an external radius token server in ISE.  The Azure server is now the Identity store I use in the Authentication Policy then, of course, AD groups for the Authorization policies.  I found the results to work just as we needed.  I did not have to set up the second authentication on the ASA.  Using the MFA as the Authentication Policy identity store now when we log into Cisco gear or the VPN we can use either a token or a push notification.  It is a little overkill for access to network gear but being a government organization we had a requirement for that.  it works much like the DUO Auth Proxy.

Hi Richard,

Do you have the NPS w/ extension config that worked with ISE integration? I am attempting to setup ISE to NPS Azure MFA for device access like you have done by using RADIUS token server on ISE. I appreciate any assistance you can provide.

Re: ISE using Azure MFA and AD

If you have your NPS server correctly working with Azure MFA, i.e. you can point VPN auth directly at NPS server and perform Azure MFA then you should be able to define the NPS server as an external RADIUS token server in ISE, ensure the ISE IPs are defined as RADIUS client on the NPS server and point VPN authentication to ISE.

 

Have you tried this and it isn't working?

Paul,

 

Doing device CLI login -> ISE -> NPS/AzureMFA as a first deployment. Would the NPS setup be the exact same as when used with ASA/VPN through NPS/MFA? If they are the same and can use the same policy, It may be a little easier to find documentation on the VPN setup.

 

Thank you,

Mark

Re: ISE using Azure MFA and AD

It should be the same. At the end of the day it is just RADIUS calls into NPS. You can match on different RADIUS attributes in NPS if you want to build different policies. If you are ultimately going to go against ISE I would recommend keeping your NPS policy as generic as possible. Basically just have it run the MFA process. All the AD group checking stuff can occur in ISE.
