• PEAP-TLS certificate

  Hello..

  I have cisco ISE 2.1 and I intend to use PEAP-TLS...

  do I need to create a certificate that is signed by a CA... ??

  or I can use default certifate in ISE... ?

  Thank you

  If you are using self-signed cert then each client must contain in the trust list.

  Cisco ISE CA Service
  The internal CA of Cisco ISE (ISE CA) delivers and manages digital certificates for endpoints from a centralized console to allow employees to use their personal devices on the network of the company. The main node of the Administration (PAN) is the root certification authority. The political Service nodes (Ssnp) are subordinate to the PAN (PEIE RA) certification authorities. The CA of the ISE offers the following features:

  Issue of certificate: valid and signed applications for certificate (RSC) for the endpoints that connect to your network.

  Key management: generate and securely store keys and certificates on nodes of PAN and the PSN.

  Certificate storage: store the certificates issued to users and devices.

  Support for Protocol (OCSP) online certificate status: provides a responder OCSP to verify the validity of certificates.

• ACS5 / ISE: PEAP authentication - first then machine user

  Hi on board,

  I have a simple question about AAA with ISE or ACS5 and PEAP.

  As we all know, is the big drawback with the PEAP Protocol, you cannot apply that property of the company not authenticates on the network.

  Example:

  Computer Windows - authentication domain and user PEAP. During GINA of Windows, the computer account is used - after login, the user account is used.

  If I bring my own iPad to society, I just have to activate WLAN, enter my domain credentials and voila! I am!

  Some companies want to restrict the network only for devices of the company.

  Therefore, is a simple solution for this, EAP - TLS - but we know all that some guys do not want to put in place an infrastructure to full blown public key...

  So here's the question:

  Is is possible to enforce an order of authentication in ISE or ACS.

  If a request for a certain MAC address of the client authentication happens (Calling station ID), this identity must authenticate with a first computer account (the prefix "host\") and that once the machine authentication is successful, the authentication of the user is authorized.

  If someone wants to connect with a user account, then this is not possible, if there was not a sign of the old machine.

  So is this possible with the ACS or ISE?

  Thanks in advance!

  Johannes,

  You can prevent ipads to connect forcing the machine authentication check the authentication of the user policy.

  You can also use the profiling feature in ISE to reject apple devices to access the network.

• ISE-Peap

  Hello

  I'm rolling!

  I saw a few people with win7 cannot authenticate to ISE:

  12520 EAP - TLS is not SSL/TLS handshake, because the customer rejected the local certificate ISE

  I thought about this: maybe have a 3rd party cert (Go Daddy) and only ISE is installed in.

  I know I have to do a Cert.Sign.Request of CSR, which corresponds to cn = primary.ise.mydomain, would also need a cert for secondary?

  GOLD:

  If I use BOND as a preferred Protocol so it does not ask for cert and the users are authenticated successfully.

  I know that they say do not validate cert and all that, but sometimes it's not popupt to them they can get just.

  Yet once maybe go with 3rd party certs will facilitate all benefiting from the use of PEAP?

  Thank you.

  Bond will not support computer authentication if you decide to go this route. It would be preferable to use a 3rd party cert, if you plan to use BYOD then use notes from apple to see what certification authority root comes pre installed version of IOS:

• ISE Local certificate and the certificates in the certificate store

  Hello

  I'm pretty new to ISE and read the document in the link below to create understanding "Local certificates" and "certificate store certificates. It seems that in the former certificate is used to identify the EHT on customers and is later used to identify customers at the ISE.

  http://www.Cisco.com/c/en/us/TD/docs/security/ISE/1-2/installation_guide...

  Now, what part of the ISE configuration told him to check the certificate sent by the client in its certificate store? I am somehow the mixture up with "Certificate authentication Profile", which is used in the identity Source sequence. But I guess that the certificate authentication profile is used to verify the certificates from a source of external identity as AD or LDAP. So where do we consider 'certificate certificate store' in our configuration of ISE.

  Thanks in advance for help out me.

  Kind regards

  Quesnel

  Hi Quesnel-

  (ISE) server certificate can be used for are:

  1 HTTP/HTTPs - is for the ISE web server that is used to host various portals (comments, Sponsor, BYOYD, my devices, etc.). This certificate is normally issued by a public CA such as VeriSign or GoDaddy. A public certification authority is not necessary, but outside your environment, customers who do not trust the certification authority that issued the certificate will get an error HTTPs warning to users that the certificate could not be verified.

  2 EAP - this is for EAP based authentication (EAP - TLS, EAP-PEAP, EAP-PEAP-TLS, etc.). This certificate is usually issued by an internal CA. The same certification authority issues usually user and/or computer-based certificates that can be used for the authentication type EAP - TLS.

  The certificate store is used to store root certificates and intermediate certificate authorities you ISE to trust. By example, if a computer is running a machine ISE authentication must trust the certification authority who has signed/issued the machine certificate. Therefore, the machine will also have to trust the certification authority which has issued/signed the ISE server certificate that you torque to the EAP process.

  Profile of teh authentication certificate is required if you want to use certificate based authentication. The CAPE tells ISE which attribute of the certificate should be used for the usernmane. Then based on that you can create more specific authorization profiles/rules information. You can also configure CAP to make a comparison of binary certificate with AD and confirm wheather or not the certificate is/has been published to AD.

  I hope this helps!

• ISE of Cisco protocols for ldap and Windows wireless client

  Only protocols below are supported by ise in combination with ldap identity sources.

  EAP - GTC, PAP, EAP - TLS, PEAP-TLS.

  Peripheral Mac OS appear to be able to use these, but Windows users seem to have problems. How windows users must connect with ise that only uses the ldap Protocol?

• ACS 5.1 doesn't have to undress Username Prefix\Suffix in Peap?

  Hello

  We got the ACS 5.1 VMWare.

  We try to only send the user name to the proxy RADIUS after ACS strip the Kingdom of Prefix\Suffix.

  But ACS 5.1 could not strip the prefix\suffix in the Peap authentication method.

  If we put the NAS authentication method to PAP_ASCII then ACS can strip the prefix\Suffix @.

  (Conditions were matched and we could see the ACS did send requests to its proxy radius server extension.)
  Any idea?

  Hi Ed,

  The point is that while the ACS can process and strip the domain name of the RADIUS Username, which is not used for PEAP authentication properly in the external RADIUS.

  The reason is that the credentials used for authentication are inside the PEAP TLS tunnel, thus GBA acting as a proxy is just transmitting this information and it doesn't have access to this information.

  Consider the RADIUS Proxy to present works even if you forward the EAP methods that are not supported by AEC, then in this case, what ACS is not supposed to touch what's inside the package of RADIUS.

  I think that in your case the only solution is to configure the field stripping on the external RADIUS server, which is the one that will be able to extract the credentials of the TLS tunnel and to transform this info.

  If it is feasible or not is based on the features of the RADIUS server for external use, but I think that you can not do much more on the side of the ACS using RADIUS.

  Examine how RADIUS proxy works and the fact that you cannot even use the external RADIUS the two ID because you can't do the field stripping and you cannot use MSCHAPv2 based auth protocols (though this would work with PAP or EAP - GTC), you are dealing with is the PEAP username on the external server or... you must instead use another way to access the announcement.

  This would open up different scenarios and maybe go away from this post

  I hope that's clear on what makes ACS and why the field is not stripped by FAC on the internal credentials.

  Thank you

• issue certificates of 802. 1 x authentication and X 509

  Hello

  Can someone please help me with the following question:

  First off I am a guy from Windows Server/PKI/AD etc. rather than CISCO, even if I have a CCNA :)

  I take care of PKI to my company and will work with the team CISCO that are the introduction of CISCO's ISE, we will use X 509 CERT on the suppliants (desktop/laptops Windows computers mainly)

  What I want to know is something pretty basic, but I saw not written anywhere

  Question 1:

  First stop, I guess it's the AAA (ISE) server is the entity that verifies the pleading certificate X 509, rather than the AP (access wireless router for example point)? is that correct

  Question 2:

  As supplicants X 509 certificate is public (for example, it is not secure and anyone can ask what it is normal) I guess the AAA server must encrypt a (random number for example) value with the public key of supplicants (of the X 509 cert) then send this value to the supplicant by which the supplicant decrypts with its private key (that no one else has as usual). Then the supplicant figure the value even with servers AAA public key (which is held in servers announced AAA X 509 cert) cela send on the AAA server and once that deciphers AAA server (with its private key) if the value matches the value originally sent to the supplicant then the AAA server can continue with authentication etc.

  The above assumption is correct?

  If the above is correct, not ISE always act like that or can you lower the security and get just the ISE server to check whether he trusts the issuer of the certificate (CRL does OK) the pleading X 509 Cert and not bother to send the encrypted packet as described above (this of course would ensure not begging-1 is actually "supplicant" - 1).

  Thank you very much in advance

  Answers:

  1 - Yes, ISE verifies the certificate presented by the device of end-user (begging) against his PB of authority certificate TRUSTED internal to import in ISE root and intermediary certificates where you use CA non-public servers (this is my case for EAP - TLS) such as Verisign, Entrust, etc. UNFORTUNATELY, ISE allows you only to have 1 cert for the use of EAP in the list (PEAP, EAP - TLS, etc.), which means that you CAN not EAP - TLS and PEAP running on different SSID. The problem is now that Entrust for example use an intermediary called L1K Entrust which is not included in trust for the devices Apple and Win 7 CA. This causes a certificate not approved for IPADs warning then you need to trust this certificate but for Win 7 features the PEAP TLS Tunnel, Setup will fail if the connection cannot be established if you uncheck "VALIDATE SERVER" on Win 7 for this SSID profile.

  2 - you can create a condition that validates the issuer cert but the authorized Protocol is EAP - TLS or PEAP so that the actual process for one of these protocols, based on my understanding is actually. For example, Protocol PEAP, the configuration of the TLS Tunnel is the 1st step, so once the configured secure tunnel then the inside MSChapv2 + EAPOL is performed and finally the data passes through the tunnel

• Cisco ACS secure 5.3 allowing foreigners on ACS local domain server domain accounts

  All the

  My company has recently acquired another company

  Each company has its own domain and controllers

  The problem:

  Executives of the absorbed company sometimes come to the main site for meetings using their own laptops

  configured for their own areas. This caused problems of authentication wireless with Windows 7 machines.

  The domain account when you connect is forcing the dispatch of the password, the name of domain user and the foreign domain

  The need:
  We need to somehow add foreign domain as the source of authentication on the local ACS authentication attempt with our wireless controllers is allowed.

  Give advice on how this could be achieved.

  Hello Steve,.

  Concerning the behavior that you experience with ACS to be able to authenticate users against the foreign domain is completely expected and you will only be able to authenticate by entering the user name and domain name.

  The only option to join the ACS for a foreign domain is LDAP configuration and in this way, you will be able to join the AEC directly with this area, however, there are several limitations on the supported protocols when you use LDAP as you can see from the following link, then you want to see if he would be available as an option for you or not depending on the Protocol that you use (which I suppose is it PEAP / MSchapv2) as you mentioned that users will type the identifying information, so it does it does not for you):

• ACS 5.0 - WLC could not authenticate

  Salvation of the Forumers

  My script is

  1 using the microsoft AD running on window 2008, use ad server to perform authentication of identity

  2. I let successfully the ACS 5.0 device link and join the domain created on the AD server.

  3. I have also set up on WLC 2100 series with the right key on pre-shared, server IP RADIUS (which is my ACS appliance IP)

  Problem statement:

  1. try to access the network Journal ACS showing the error log 'Unknow CA, a no authentication'. (I know I'm missing to place certificate for EAP protocol somehow...)

  Question:

  1. to solve this problem, I can generate self-signed certificate ACS, then let the WLC import the certificate self-signed GBA?

  (so EAPoW challenge can happen as ACS and WLC are reciprocal trust, which, in my view, ACS simply use the user of the AD, so in this cse ACS database is the authentication server and WLC is the authenticator and my AP / user's begging him, am I rite?)

  can I not like it? Appreciate all feedback and response!

  2. If we are not my thought, can you please suggest me a solution (my requirement, it is not using any third party trusted agent certificate)

  Thank you

  Noel

  Hi Noel,

  If I can update your list, the components must be the following:

  -ACS authentication server =

  -WLC = authenticator

  -wireless client = client

  Use of certificates for EAP authentication between client wireless and ACS (devices performing the EAP authentication): the WLC check all ACS certificate.

  You can certainly create a self-signed certificate on ACS for PEAP for example working.

  On the client, you must then either not to validate a server certificate or to import GBA self-signed certificate as a CA certificate root to trust the self-signed certificate ACS itself when sent by ACS during the configuration of the PEAP TLS tunnel.

  One final note, for WLC working with ACS 5.0, please make sure you are on the patch
  5.0.0.21.6 or later

  Hi Eric, this error message indicates that the client attempting to authenticate does NOT approve the CA that signed the certificate to your servers from ISE. You use a self-signed certificate or do you have a public certificate from a public CA such as VeriSign, GoDaddy, etc.?
