• AnyConnect VPN client authentication using certificates

  Guys, I'm trying to configure my ASA5505 to authenticate the AnyConnect VPN clients using certificates. I have 'Certificates' defined as my method of authentication in my AnyConnect connection profile (see screenshot), but I get 'Certificate Validation failure' whenever I try to connect. The certificate I want to use is a computer issued by my CA certificate company root (Windows Server 2008 running Active Directory Certificate Services). Screenshot of certificate is attached. I added the root certificate on the SAA, and I tried all kinds of combinations by using the corresponding certificate in the AnyConnect Client profile. Each attempt failed, and I'm having no luck finding documentation on how to proceed. Any help would be greatly appreciated!

  Hello Shaun,

  The problem you're describing, not be able to authenticate through certificate through Microsoft Internet Explorer, is the fact that the certificate is in the computer store.  You do not want to confirm with Microsoft, but, I understand that only Microsoft Internet users explore the user store, this certificate is not available to attend the ASA via the Internet browser.

• Machine using certificate authentication

  Hello

  I am facing this error while the machine authenticates agaist AD for wireless users. My requirement is users with company laptop get vlan privileged and BYOD should get vlan normal. I use Cisco ISE 1.1.1 and rules of authentication configured in client diffrenciate based on the assets of corp and BYOD. Result of the authentication policy is sequence of identity that uses the certificate profile and AD. All laptops Corp. must be authenticated using certificates and then followed by past and user of the AD. When I set up XP users to validate the certificate of the server this error comes in Journal of ISE "failed authentication: 11514 suddenly received empty message TLS; treat it as a rejection by the customer' and if I turn off validate sewrver certificate then this error "failed authentication: 22049 binary comparison of the certificates has failed."

  Any help?

  Thanks in advance.

  Hello

  It is a limitation on native begging him, when you activate the smart card or certificate of authentication for the network connection, and then he tries to use it for the computer and user authentication. It does not use certificate for machine auth authentication and authentication of the password for the user authentication.

  You can use the anyconnect Network Access Manager (which is free if you have a cisco wireless network) and not only it allows you to define what type of desired authentication (certificate of machine) and password for the user, but it has a new feature called the chaining of eap. Chaining of EAP is a powerful option because you can choose the order (machine first then user) when the client connects to the network. You have is no longer to point out about machine authentication timers and I was wondering what that is best suited when it comes to registration of users in and out of their machines in order to refresh the cache of authentication machine at ISE. However chaining eap uses eap-fast, which is a framework for authentication based on the CAP.

  This is the last note of release on this feature (currently in beta):

• I have here a way to force the client to use a virtual IP address?

  If a client makes a connection between a server where multiple IP addresses are active - is there a way to influence that one is chosen for outgoing traffic?
  Background:
  The application is moved as well as its virtual IP address.
  After reinstalling the "sender address" should be the same for the tcp.invited_nodes-based IP filtering.
  
  Thanks in advance!

  Or boil down to the question: is there a function for connection sqlnet as "-b" for ssh?

  Nope. Don't remember seeing such an option. Server side, this feature is of course available to bind endpoints tcp specific IPS.

  Why exactly do you need this function on the client side? I don't understand the "+ the client connects using the IP addresses changing, even if the application is to have a virtual IP unique and constant. "This requires a source more open on the FW between DB and the customer as necessary +" problem you stated.

  If the client opens 2 connections to the base, then it will be 2 connections through the firewall. As the private client port will be different for each connection and make the unique connection.

  Now if these 2 client connection use IP1 and IP2 on the client for the connection, won't matter - as 2 separate connections will be created independently.

  If for some reason you want to from the db server or firewall see these client connections entering as minimum IP sources - then you can do this by using a unique IP address for all incoming connections by NAT'ing.

  You ask a NAT firewall (using iptables for example) and simply rewrite incoming IP headers for tcp on 1521 packets the IP NAT and transfer the package on the firewall/db server.

  This server will see a unique client IP only for all inbound traffic. Works pretty well for Oracle that the client connection string includes the hostname of the client/hostid - so you can always in Oracle see what session is from a client who, despite all these sessions with the same source IP address.

• Error: Tunnel research group using certificate cards failed for the peer certificate

  I have the research group of the Tunnel using certificate cards failed for peer certificate error when signing the SAA on my SSL VPN. I have the certificate installed on the client, I have no mapping of certificate created.

  I can map user certificate to a user name used to connect to the SSL VPN?

  Y at - it good documentation describing the certificate mapping?

  Off topic: I listen to a podcast of TAC security this week, and one of the members of the Group of experts preparing for an introduction to PKI to Networkers (I don't remember not the year). Videos of these presentations are available?

  Once more, I appreciate all the help.

  Hello

  I guess the previous fill command comes in the webvpn under tunnel like this group attributes:

  tunnel-group test general attributes

  user name of certificate-CN

  tunnel-group test webvpn-attributes

  pre-fill-username-customer ssl

  No aaa authentication

  aaa authentication certificate

  You can also specify which field of the certificate you want to that username is taken.
  Users will be able to change the username (which beats the objective right?), but then they will not be able to connect using any other username. So if they change they will not be able to connect.
  Also, you can use the username to hide which will not allow users to change the user name it will be greyed out.
  And Yes, it's essentially a double authentication coz we use the certs and aaa to authenticate a user.

• The ASA - Client to use SSL and connections options I have?

  We have a large site and have only allowed using IPSEC for all our branch in branch and the user tunnels. We tried SSL years but she limits so we stopped deployment. We must now begin the SSL VPN user and I have a few questions basic ASA.

  I have a unused ASA 5510 for tests that currently holds the 8.3.2 on it, Security code more license, 100 SSL VPN peers and 250 total peers of VPN, VLAN max 100, 2 seconds, active/active contexts, 2 proxies of phone CPU and everything else is disabled. We do not intend on using a SSL connection web anywhere (Anyconnect essentials?) and will not use the entire customer VPN SSL which will be hand loaded on machines or downloaded from the ASA and loaded on the computer if possible. I want to know is what version of the current code can install on my ASA without losing my existing SSL VPN 100 peers license and that the Anyconnect customer would be sustained? I've seen talk about premium Anyconnect but do not know its relationsonship. If I improve the ASA of new releases or versions of code my peer SSL VPN license turns into an Anyconnect Premium license?

  Any help to get started you in the right direction would be appreciated. I know I can spend days trying to understand Cisco licenses and traps and still get burned in the end with the function or the wrong license. Basically, I want to know what I have to install the end-user complete SSL VPN clients and I have to do with the ASA to provide this functionality with current license / feature set there. I also want to know what the end user should be used because it seems that Anyconnect Secure Mobile is the same if I use all its security features. Example - I am not able to check for firewall/malware etc programs but we currently have a policy in place which does not allow browsing the Internet or access when end users have connections VPN tunnel on our site. That restriction will always be kept if this is possible thanks to the SSL VPN connection also.

  Thank you

  Paul

  The SSL VPN client-based license will remain active on your box through Software ASA updates later. AnyConnect Essentials (which you already have) will work with the feature of SSL VPN license.

  You would be upgrading to AnyConnect Premium only if you wanted to add features like clientless SSL VPN (purely based on a browser) or other items such as Advanced Endpoint Assessment (AEA). AnyConnect Premium can coexist with Anyconnect Essentials on the SAA even if you can't mix and match licenses Premium and Essentials.

  Essential distinction or Premium is mainly directed towards the installation of the ASA. The same AnyConnect Secure Mobility client software (version 3.1 is the latest for Windows and OS X and is quite a nice new version) is used in both cases. Functional additional client plug-ins are things such as the AEA and the NAC 802.1 x. Your group policies based on the SAA as no split tunneling, etc. remain in force.

  If you intend to allow clients of mobile devices (iPhone, iPad, and Android (a very limited support for the last BTW)) to access your VPN, you will need to add the mobile on the SAA AnyConnect license and install the client from the respective AppStore. Note that Windows Phone and Blackberry don't are not supported as client AnyConnect.

• Generate certificates for use with the VMware SSL certificate automation tool

  Hello

  I am trying to use the tool to automate SSL certificate. Our vCenter Server is configured in pulse mode. When I'm trying to generate the request (CSR companies) for Single sing - on (SSO) of certificate signing, option 1 is to provide the FULL domain name. I want to know what domain name FULL should I provide the name of the node or virtual.

  Also I will try to use this tool for other components like updatemanager, inventory service, service of vcenter server, web client. Have experience how to use this tool?

  Thank you

  I successfully replaced certificates for all services. I used the FQDN of the virtual name and not the name of the node to generate the CSR. Thank you

• Media Center Question can I have set up as a server and the other two as clients, each using two of the tuners of the card?

  I have 3 computers running Windows 7 Professional, one of them has a four installed tuner DVB - s2 card. I want to configure it as a server and the other two as clients, each using two of the tuners of the card. I understand the media library is able to use the basic network TV tuning cards, so there must be some way for me to configure the server to send the information over the network.

  Any ideas?

  You will not be able to use your existing tuners like tuner network. Microsoft has
  arrested development of Media Center, so don't expect any new hardware/software to
  appear.

• Cisco ASA IPSEC from the understanding of a site to tunnel auth using certificates

  assuming that my company and another company (BBT) attempt to set up a tunnel to a site by using certificates. lets say we have asa 5520 s and have agreed to use says that our certification authority.

  On my end, I do registration certificate using SCEP Protocol and suggests that the end BBT is set up exactly the same way.

  First, I generate a pair of keys RSA - Im assuming that it is key to my ASA public private for the encryption and decryption-(pls correct me if wrong Im)

  Then I set up a trustpoint to registration certificate (in this case, it will be Server CA Entrust). I will set up my full domain name and the parameters of CRL.

  Then, I get a certificate of the AC CA. This package contains a fingerprint of the certificate which is loaded on my ASA. apparently - the fingerprint of the certificate is used by the 'end' entity to authenticate the received CA certificate. Why would the final entity to authenticate a CA certificate that has already been installed on this subject?
  In other words, what really does this print? Surely this cant be the same footprint that GETS installed on the BBT ASA?

  Finally, I request and install a certificate of identity. It asks for a password? I believe that it is used in case I want to make changes to the certificate, such as the revocation of the certificate. (Once again, please correct me if wrong Im)

  a few additional questions

  during the phase of authentication isakmp how my asa verifies that the certificate that the ASA BBT sent was indeed signed by the certification authority approved. How exactly?

  My ASA and ASA BBT must trust the same CA. In other words, it must be set up the same trustpoints?
  or can I have to entrust CA server as a trustpoint and verisign?

  How the certificate authentication process works since the ASA receives valuable traffic through the exchange of encrypted data?

  1 million thanks!

  Hello west33637,

  You can read this document to get a simple example of setting up a VPN S2S using certificates on an ASA

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080aa5be1.shtml

  I would try to separate your questions and see if I can answer.  I will speak without using the SCEP Protocol because it adds a layer of complexity that can be confusing.

  (Q) Comment can I get a certificate?

  1 generate a RSA key pair.  A pair of RSA keys as you indicate has a public and private key.  Public and private keys are large number created by multiplying the other prime number (very simple explanation).  These keys are used for encryption simple control.  The private key is kept private and never awarded.  The public key is provided for everyone through the certificate received from the device.

  Data encrypted by the public key can only be decrypted by the private key and vice versa.

  more details here: http://en.wikipedia.org/wiki/RSA

  2. we create a trustpoint (container to configure and set parameters in the certificate).  In the trustpoint that we associate the RSA key pair, give a name (usually the FQDN of the server that will present this certificate), configure if certificates that are authenticated by the trustpoint must also be checked in the LCR... etc.

  3. then we can create CSR using the crypto ca enroll command.  Now, we take this REA and provide it to Entrust.  If this is done via the SCEP protocol you would have already done the next step of the authentication of the trustpoint.

  4. When you receive a certificate from a third party, such as Entrust, they should also provide the certificate chain that allows the authentication of the certificate that they have signed all the way upward at the root (self-signed certificate server, the certificate must already be approved by most of the systems of operation/web-browsers).  We want to install the string in the ASA because the ASA does not trust any certificate by default, it has an empty certificate store.

  5. on the SAA, we now install the string provided by Entrust.  Usually your identification certificate will be signed by an intermediate CA, just like the certificate of supportforums.cisco.com.  Trustpoint ASA system for a CA (root or intermediate) and an ID (identity) by trustpoint.  So we will probably have at least a trustpoint more.

  Crypto ca trustpoint Entrust_ROOT

  Terminal registration

  output

  authenticate the crypto ca trustpoint Entrust_ROOT

  Don't forget to use trustpoint names who will lead them to you and your organization.  Create a trustpoint for each of the CA certificates except for the signer of the certificate direct to your ID.  Authenticate the signer directly in the trustpoint even where you install your certificate ID.

  the import of crypto ca trustpoint ID certificate.

  You should now have a fully usable authenticated certificate.  PKCS12 import require a certificate to decrypt the private key that is stored in a PKCS12.  But if you generate your CSR on the same device that when you install the certificate, then it would not need to export PKCS12 and a password.

  ---

  A small side is not on the signature, a signature of certificate (fingerprint), also known as the name of a digital signature is a hash of the certificate encrypted with the signer's private key.  As we know, whatever it is encrypted with a key only can be decrypted by the public key... all those who approves the signer's public key.  So when you receive the certificate, and you already trust the signer, then 1) to decrypt the signature and 2) check that your certificate hash table corresponds to the decrypted hash... If the decrypted hash does not match then you do not trust the certificate.

  For example, you can watch the certificate for supportforums.cisco.com,

  The topic is: CN = supportforums.cisco.com

  The subject of sender (signatory) is CN = Akamai subordinate CA 3

  Akamai subordinate CA 3 is an intermediate certification authority.  It is not self-signed

  CN = Akamai subordinate CA 3 issuer is CN = GTE CyberTrust Global Root

  CN = GTE CyberTrust Global Root is a certificate root (Self signed).

  We would like to install this entire chain in the ASA so that we can provide this certificate and chain to any device and safely as long as this device trusts CN = GTE CyberTrust Global Root, then it should be able to verify the signatures of the intermediary and, finally, our certificate of identity of us trust.

  ---

  Looking for another post to do a quick discussion about how the certificate is used in ISAKMP and IPSec.

  Kind regards
  Craig
