ACS - host restriction

• WLC / ACS / AD - domain and laptops no - domain (802. 1 X / PEAP)

  Hi all

  I implement a solution based on 4404 WLC, 1113 ACS and Microsoft AD. What I want to achieve is to have two WIFI (SSID), that can be used by users on laptops of the domain, the other can be used by the users in the domain on personal laptops. Field portable computers will have full connectivity, but personal laptops will be restricted.

  I created the two SSID using 802. 1 X by ACS / Remote Agent and can authenticate and connection OK.

  I thought I should have user auth and auth machine for laptops of area but just user auth for personal laptops.

  I have unauthenticated machines go to one group ACS or blocked, but I need to enable them in if they are on the SSID restricted. I can't quite understand how to have two SSID is authenticating with the same ACS / AD - one green and the other.

  I'm on the right track?

  Anyone done this before or have any bright ideas?

  See you soon,.

  With the use of WLAN access based on the SSID, users can be authenticated based on the SSID they use to connect to the WLAN. The Cisco Secure ACS server is used to authenticate users. Authentication happens in two stages on the Cisco Secure ACS:

  1 authentication EAP

  2 resulting SSID authentication of network (NARS) on Cisco Secure ACS Access Restrictions

• ACS 5.3 user authorization based on MAC address

  Hi all

  I hope someone can help me more.

  A short background. Our company SSID is being migrated to use PEAPv0 to EAP - TLS. This limits access only to the books of the company. In addition, we have bar codes scanners used to inventory assets. These devices are not able to use EAP - TLS as they can not be integrated in the field and be unable to make the certificate-based authentication.

  As a solution, we are planning to use a different SSID with access to the same network, but using PEAPv0 as authentication, basically the same SSID but with a different name. As this naturally allows anyone to access the corporate network with a name of user and password valid now, I wanted to add another step in the process of authentication - MAC of the device.

  I know I can do the filtering on the WLAN controller, but as it has a database limited as well as the fact that it is difficult to keep the MAC list on all the controllers of I thought I can do this on our ACS system.

  I am now trying to accomplish the following:

  The user is authenticated via the store of internal users, that is successful. Now, I want to allow the user via the MAC address, which is stored in the internal of the ACS host store, whether access is allowed or not.

  To do this, I created the following strategy:

  Service selection policy-(result rule based selection)

  --(NDG:Device Type dans tous les appareil type: sans fil et RAYON-IETF: Called-Station-ID contient ) | Result: PEAP access

  -Default | Result: DenyAccess

  PEAP access service
  

  Identity: Internal users-(selection of single result)

  Authorization-(result rule based selection)

  -Host: HostIdentityGroup internal in all groups: Valid_MACs

  When I then try to access the wireless network I don't get authenticated. The error I get when I look in the logs:

  15039 selected authorization profile is DenyAccess

  Is it not possible to use an identity as "attribute based" store to the other identity store?

  Kind regards

  Patrick

  This can use an end station filter

  define the elements of policy > Session Conditions > network Conditions > end Station filters

  Can define a list of MAC addresses; can be imported and exported from a file

  To include in the policy authoirzation; customize the authorization policy to include the status of "End Station filter" and select the object end Station filter defined that you just set

  The feature of Cisco ACS NAR (restricted access network) with RADIUS does not work with CSS. This is because the radius NAS-IP-Address attribute is set to 0.0.0.0 in the Radius authentication request.

• Restrict calls remote modem with ACS

  Hello..

  Using ACS I try to limit the reverse telnet access to a modem which will later be used by TTYredirector. I want users to have access to the modem only. We are on 3.01 ACS (yes I know old)...

  When to use access to the network with device restrictions: 2065: * (being the assigned line port 2065) subscribe to the denied service service = raccess tty65 in the journal of the attempts failed.

  Do I need to add this service to the GANYMEDE + under Interface Config?... What is the params? I tried to just raccess in services which added a section under user/group that I chose but nothing else.

  I have the router:

  AAA for authorization Ganymede + default reverse-access group

  Welcome tips, google has attracted so far zero.

  Paul

  Paul

  It's not the NAR causing the problem-, this would result in a message 'filtered user' in the failed attempts.

  Looks like the problem is that your group configuration is not allow the raccess service.

  Because this isn't a standard service preset in ACS you config sys goto then Ganymede + (ACS) and define a service personalized Ganymede. Call it "raccess". In the settings group, you will then be to activate and define all the attributes you need.

• Machine access restrictions in ACS 3.3

  Can someone tell me how to implement on a device ACS 3.3 Machine access restrictions?

  Machine must be a member of the domain / company before access to the wireless local area network is permitted...

  DRM

  Remco

  The configuration you have the GBA:

  -Authentication verified machine

  -MAR activated, i.e. you checked, 'group authentication successful without authentication card machine' to a group, generally «»

  Configuration of the client/supplicant:

  -Client configured to send authentication of the computer information.

  You take a computer that is part of the AD and was introduced on the network. This is the first time.

  Start the computer to the top (for the first time).

  Computer is configured to send credentials to the Machine, so he sends to the switch, sends switch ACS, ACS verifies whether or not the machine is a valid machine.

  If this is the case, put in cache 'Calling-Station-Id' for the interval configured in this section.

  (End user still cannot do anything yet, because MAR is still in process)

  Computer has completed the guest of GINA.

  End user presses Ctrl + Alt + Delete.

  Type username/password (first time).

  Computer transmits the credentials of the user to switch, then switch to ACS, ACS gets it checked against AD.

  If the user is a valid user, the user is mapped to an ACS group, according to the mapping and is in.

  IF the user authentication fails, even if the computer authentication succeeded.

  Now, it was one of the scenarios, other is,

  Your machine is NOT part of the AD, so eventually Machine authentication will fail. Suppose that the user trying to connect in network has a name of user and password valid, but the computer using the the it is not a part of the AD.

  Then, you will get an error during the machine on "supplicant" as authentication.

  You cannot connect blah blah area...

  But you will be allowed to provide your name of user and password combination.

  Generally MAR is implemented to restrict this access, i.e. users trying to connect into the corporate network using non-active society, who are the majority of the infected by the virus at the time.

  It is the point where this option comes into play,

  "Group card for user authentication successful without authentication machine."

  So even if the authenticated user successfully, but from the machine that is not part of the AD, the user will be mapped to the group according to the above option.

  What 'Calling-Station-Id' caching.

  Even if the authentication was successful. ACS will check if the Calling-Station-Id is cached for the machine from where comes the good name of username/password? If this isn't the case, you use a wrong machine to connect to the network.

• Cisco ACS restrict a user to specific routers

  Hello

  We have ACS v3.2 in our network, I created a new user and added to a group, is it possible in this group to specify what routers / switches to the user is able to telnet, with some sort of ACL or something? I read something on:

  Filter access network (NAF)

  which is available in 4.0, should I upgrade to be able to do this?

  I tried to put a group defined Network Access Restrictions, but this seems to be what network you are telenting from?

  Sorry, please have patience, I'm new on ACS

  Thank you!

  Hello

  I use ACS v4.2 so don't know if you'll get the same features, but you can select the NDG your routers reside in slot per group defined Network Access Restrictions > drop-down list AAA Client? If so simply select each NDG, you want this group to have access to the break-in * in the Port and * address. This will allow any IP address telnet/ssh power for devices in each NDG you enter.

  If you wish you can control the IP addresses that access your routers by placing an access on each router list (stops messing around with that stuff, if you're not familiar with it).

  I hope this helps...

• Import of host internship ACS 5.0

  Hi all!

  I would like to import some hosts of GBA. I know, the ACS gives a model in a CSV file, but I do not download anything. Can you help me?

  Model:

  MACAddress:String (64): Required, description: String (1024), "enabled:Boolean(true,false):Required", HostIdentityGroup:String (256)

  This is the process for importing hosts in ACS 5.0

  1) go to

  Users and identity stores:... > internal identity stores > hosts, press "Import" and then "Download Template".

  (2) open the model file. The first line should be left unchanged. Underneath, the records must be added with a record for each host

  An example of the minimum value that must be set for a host is illustrated below:

  11-22-33-44-55-66,,true, / / / group identity is left blank and the top-level node is assigned

  Format of each line is,

  Each record occupies a single line. Save the file

  (3) once the documents are created, press "import." Select the file 'step 2', then press 'Start Import'. Import the host records should begin. All errors will be displayed in the progress window

  Note that ACS 5.0 allows to add new rcords. the ACS 5.1, can also modify existing records and export. ACS 5.1

  2) go into Restrictions on access network (OAN) option.

  (3) by user defined network access Restrictions.

  (4) check "define CLI/DNIS-based access restrictions.

  (5) select "reject the call or Access Point.

  (6) in the dropdown AAA client list - select the name of the device on which the user does not connect.

• Cisco Secure ACS 4.1 - blocking attempts to authenticate to a specific host

  We use the application of RADIUS of ACS 4.1 for both wireless 802. 1 x and for our old PIX 515E authentication, as well as a few other features.

  We try to migrate users off the PIX and want a method of disabling their ability to connect through the PIX once we have them migrated to the new method of remote access.

  Authentication in ACS logs show the IP address of our PIX under "NAS-IP-Address" as the source of the authentication attempt.

  Is there a relatively simple/easy way to block this IP address attempts (which causes these attempts fail) all by allowing wireless systems and others to proceed as usual on a per user basis?

  Brian:

  If I have understood correctly, you must allow users to connect to the wifi but prevent users to connect via PIX.

  What you can do is to create a configuration of access network (OAN) Restriction under the config görüş (or under Configuration user if each user).

  See this image:

  

  If you don't see the network access restrictions config under the user and/or group config, you can activate the Interface-> advanced options configuration.

  You can create a sequence of identity store so that if the end point is not present in the ldap database, then it can check its database of the local host.

  Or you can create a condition in your selection of service such as if rule called-station-id ends with (AIDS) then you can have it match the rule that uses the appropriate rule pointing to ldap, another rule when called-station-id ends with (ssidB) match the rule that points to the rule that uses the database of the local host.

  Here is the section on the configuration of the sequence of identity store, don't forget to select continue if user not found.

• ESXi on the host system with a physical restriction of the MAC

  Hi all!

  We have installed on a host system, located in the data center with restriction of MAC on a physical map of ESXi.

  Earlier, we have VMWare Server 2 with bridged network, it was not a problem.

  All virtual servers is accessible via port forwarding.

  About ESXi I can't found any solution to create the bridged network.

  Please give me a tip on how to solve this problem.

  Create a vswitch with no physical cards.  To connect VM to that (and a management vmkernel ESXi).

  Next, install a virtual firewall as vyatta connected to the vswitch isolated and the default vswitch with the physical card.  Then configure port forwarding rules as required.
