• Access VPN ASA and cisco ISE Admin

  Hello

  Currently I'm deployment anyconnect VPN Solution for my client on ASA 9.2 (3). We use the ISE 1.3 to authenticate remote users.

  In the policy stipulates the conditions, I put the condition as below.

  Policy name: Anyconnect

  Condition: DEVICE: Device Type Device Type #All Device Types #Dial - in access EQUALS AND
  RADIUS: NAS-Port-Type is equal to virtual

  I'm authenticating users against the AD.

  I am also restrict users based on group membership in authorization policies by using the OU attributes.

  This works as expected for remote users.

  We also use the ISE to authenticate administrators to connect to the firewall. Now what happens is, Cisco ASA valid also against policy, administrators and their default name Anyconnect.

  Now the question is, how to set up different political requirement for access network admin and users the same Firewall VPN.

  Any suggestions on this would be a great help.

  See you soon,.

• Cisco ISE CLI and GUI password expires

  I got Cisco ISE version 1.1 I am facing a problem with the password CLI and GUI, it expires and I can not connect, I do password reset using the DVD of the ISE.

  I naviguer navigate to the CLI of ISE, then perform the following commands:

  conf t

  password policy

  no password-expiration-enable

  and reset the password of admin GUI, using the command:

  # reset-passwd ise admin request

  from the interface of ISE I delete option for the devil admin account after 45 days.

  but after 60 days, the password expire again.

  kindly advise what to check for this question expires.

  Hello Mostafa,

  Yes, the last answer was more towards past-mgmt GUI because in the majority of cases, it happens with the administrator account on the user interface. I need to know if you've restarted the ISE after disabling the expiration of the CLI, because what I read a few weeks in an internal fault which password policy settings are not preserved on cli after restart so just to check could please check current on CLI w settings / help to see the race. in the password policy.

• Renew the certificate - Cisco VPN (the router)

  Hello!

  I have to renew my certificate and I need to do this, generate a new CSR.

  My doubt is if I generate a new CSR my current certificate will be lost or not.

  The command I use to generate a new CSR is:

  # crypto ca enroll XXX

  Thank you.

  Hi Anderson,

  If you create the CSR in a different trustpoint, you will not lose the current certificate.

• Cisco ISE synchronization and NTP server

  I am currently implementing Cisco ISE to our customer.

  But having a little problem Cisco ISE cannot synchronize with NTP server.

  Keep in mind, NTP servers in AD.

  Currently, Cisco ISE synchronize just at the local level.

  Cisco ISE implemented distributed mode, when there are two Cisco ISE installed on VMware (Administration & monitoring primary & secondary node), and another is the device (political Service node).

  As a result of it might not sync server NTP and the ISE of Cisco, Cisco ISE often OUT-OF-SYN.

  Is there a solution for this problem?

  Gandhi,

  This is a known issue, I have crossed upwards and have not read that you use AD as your NTP server, there have been problems with integration of the ISE and ACS with AD as their ntp source, please use another device like sources ntp, for example a router.

  Thank you

• Press release cisco ISE 2.0

  Can someone please recommend a good book on ISE 2.0... again 2.0

  IMHO there is no good book on ISE 2.0 because there is no book of ISE 2.0 at all.

  IM aware of only three books on ISE:

  • CiscoPress: Unified Cisco ISE BYOD and blocked access
  • CiscoPress: CCNP security SISAS 300-208 official Cert Guide
  • Syngress: Practical deployment of Cisco Identity Services Engine (ISE): concrete examples of deployments AAA

  I did the first and also know each other. They n 't ISE 2.0 coverage. And looking at the table of contents of the third, it looks no better.

  Not a book at all, but the best documentation for ISE is ISE product page design guides: http://www.cisco.com/c/en/us/support/security/identity-services-engine/products-implementation-design-guides-list.html

• Is it possible to map a promoter group in Cisco ISE to a group of users in Active Directory, using a RADIUS server?

  Hello!!

  We are working on a mapping between a promoter Cisco ISE group and a user group in Active Directory, but the customer wants the mapping through a RADIUS SERVER, to avoid the ISE by querying directly activate Directory.

  I know it is possible to use a RADIUS SERVER as source of external identity for ISE... but, is possible to use this RADIUS SERVER for this sponsor group manages?

  Thank you and best regards!

  Hi Rodrigo,

  The answer is no. There is no way to integrate the portal Sponsor config with a RADIUS server. Your DB for authentication Portal Sponsor options;

  AD
  LDAP

• Renewal certificate HTTPS in Cisco ISE

  Hello

  A few months ago a renewed our certificate for eap. Now, I must renew the HTTPS certificate. ISE said that there will be a 'significant' downtime, the renewal of the certificate.

  What exactly is this judgment? Cannot authenticatie users through EAP / RADIUS?  Or is that what the web interface? I can't find any documentation on this topic.

  Kind regards

  Michael Trip

  The only downtime, you can expect the renewal of the HTTPS certificate is:

  1. for changes to HTTPS protocols, a restart of the ISE services is required, which creates a few minutes of downtime. You will not be able to access the GUI round 10-15 minutes.

  2. If you are using a self-signed certificates in a distributed deployment, the primary self-signed certificate must be installed in the approved certificate of the secondary server ISE store.  Similarly, the secondary self-signed certificate must be installed in the approved certificate of the server main ISE store. This allows the ISE server to mutually authenticate each other.  The deployment might break. If you renew certificates from a third-party certification authority, check if the root certificate chain has been changed and update the store of certificates approved in the ISE as a result.

  Here is the document containing the same steps. I have highlighted for your convenience.

• Cisco ISE 1.2 and the ad group

  Hello

  I have Cisco ISE installed on my EXSi server for my test pilot. I added several ad groups at ISE as well.

  I created a condition of authorization policy, that is WIRELESS_DOT1X_USERS (see screenshot)
  Basically, I just replicate the default Wireless_802.1X and added Network Access: EapAuthentication, Equals, EAP - TLS.

  My problem is, I have been unable to join the wireless network, if I added my ad group to the authorization strategy (see screenshot). The user I is a member of WLAN USERS. If I removed the authorization policy group, the use is able to join the wireless network.

  I have attached the screenshot of ISE newspapers as well. I checked the ISE, AD/NPS, WLC, laptop computer time and date, and they are all in sync.

  I also have the WLC added as NPS client on my network.

  I checked the newspaper AD and I found it, it was the local management user WLCs trying to authenticate. It is supposed to be my wireless user Credential is not the WLC.

  It's the paper I received from the AD/NPS

  Hello

  The problem is with what ISE name, it's choosing to search of the AD. If you look in the ISE newspapers down, you'll see the username that use ISE (firstname, lastname) to search for the AD.

  In your certificate template see what attribute containst name AD (possibly the dns name or email or the name of principle of RFC 822 NT), go to your profile to authenticate cerificate and use this attribute for the user name.

• Cisco ISE 1.1.2.145 Admin authentication via the LDAP protocol

  I have configured the LDAP protocol and able to retrieve our LDAP directory structure. Now, I'm trying to point authentication "Admin Access" Source 'External identity', which is the new LDAP IS I created. But I couldn't find an option to authenticate locally if for some reason the LDAP configuration does not work. I learned that the ISE can automatically return to local auth as external sources Idenitity are inaccessible. How can I test the LDAP authentication with breaking them our Admin Access? I thought to open two parallel sessions, one with Super Admin account Local and one with the domain account. But I noticed that ISE communication is smart enough for the closing session/connection no matter what other sessions in different browsers so, basically, I can't open two parallel sessions the same machine to test. Suggestions? or am I missing something here?

  Thanks in advance.

  Hi Srinivas,

  Even if you configure LDAP as a source of external identity of admin access, you can always internal relief without having locked. According to the ISE user guide:

  During the operation, Cisco ISE is designed to "fall back" and try to perform the internal identity database authentication, if the communication with the external identity store has not been established, or if it fails. In addition, whenever an administrator for which you have configured external authentication launches a browser and initiates a logon session, the administrator must still the option authentication of demand through the local Cisco ISE database by choosing 'Internal' to the Selector drop-down storage of identity in the Connect dialog box.

  http://www.Cisco.com/en/us/docs/security/ISE/1.1/user_guide/ise_man_identities.html#wp1351543

  Please see the attached screenshot by my lab ISE:

  

  I configured the admin authentication against AD, but I still see both 'Internal' and 'AD' at the time of the connection.

  I hope this helps.

  Thank you

• Renew the certificate of identity on Cisco ASA 5505, do I have to renew all user certificates?

  n00b questions.

  I have to renew my SSL certificate of identity soon on my Cisco ASA 5505.  I'll have to renew all my certificates for client on their devices, so they can establish a vpn tunnel?

  Hi dsartoros,

  If you encounter a self signed (generated locally) identity certificate renewed, then you will need to download this certificate on the clients so that they can connect without getting "untrusted server certificate error".

  If you renew a certificate issued by a 3rd party CA (sending of CSR to CA) and certificate, then you will not need to make any changes on the client as they already trust the certification authority that issues the certificate first root.

  Kind regards

• Renew the certificate in Cisco ACS for PEAP authentication

  Hi, we installed in laptops wireless customer a certificate created by Cisco ACS to authenticate, but its about to expire.

  How can I do to renew the certificate whithout affecting users.

  (1) Yes, we can generate a new cert but install the latter.

  (2) install generated new cert on the client.

  (3) install the new cert in ACS.

  Good plan and will probably work.

  Hello everyone I have a cluster ise 4 devices. 1 main admin/secondary monitor, admin of admin/primary secondary 1 and 2 knots of policy

  I need to install the Cert CA public on them. can I generate 1 CSR on one of the nodes, which includes a San with all the nodes DNS names?

  So get 1 single certificate by the CA and export and import the cert even in all other nodes?

  or do I have to generate 1 CSR for each node and 4 certificates of purchase? Wildcard certificates is not an option. Thank you

  Yes, you are right. The document was created before ISE 1.2. You can generate the CSR from the interface of ISE and add SAN.
