TACACS config for PIX & ASA

I am struggling in configuring the TACACS configure to allow authentication via Cisco ACS, I could able to configure for switches 2950,3750 but not with ASA & PIX, can any let me know the configs?

I am actually looking for a similar command which I used on the Cisco 2950/3750
aaa new-model
aaa authentication login default group tacacs+ enable local
aaa authentication enable default group tacacs+ enable
aaa authorization exec default group tacacs+ if-authenticated
aaa authorization commands 1 default group tacacs+ if-authenticated
aaa authorization commands 15 default group tacacs+ if-authenticated
aaa accounting exec default start-stop group tacacs+
aaa accounting commands 1 default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
with this commands I could able to track the command what all the user has used, logs with the user name which I configured on TACACS, the command which you have sent me I could able to login with the TACACS user name "aaa-server TACACS+ host " but it is not accounting all the details like login & logout time, command what the user has issued etc..

  • TACACS+ configuration for Cisco ASA

    I tired configuring TACACS+ configuration for ASA but unable to complete it. I have ACS 3.3 for all other Cisco Routers and Switches

    Leo,
    I was looking around and come across this post. It's very late, however, wanted to add my inputs for other community members.
    RSA Token/One-Time-Password support available with ASDM only in SINGLE ROUTED MODE. If you are in Single Routed Mode, you can do OTP with ASDM if you are running ASA 8.2+  with ASDM 6.2+.
    If the firewall is running in multi-context and transparent mode. It won't work. Below is the enhancement request that was filed for the same feature to be supported.

  • AAA config for PIX

    Hello folks!!!
    In my PIX 515E I hv configured AAA configuration(tacacs+) & hv also configured serial console authentication as "local" & telnet console authentication from tacacs+ server.Apart from this I hv also configured authorization as "tacacs+" server.Now if AAA server is not available Iam able to go in to user mode with the "enable pwd" set in PIX but if I try to go into enable mode it gives error msg "AAA command authorization failed" since it looks for AAA server for authorization & that is not available.Is there a way by which I can overcome this by configuring "local" authorization as a fallback incase the AAA server is not available
    Cheers
    SS

    You can add a command like this
    aaa authentication login default tacacs local
    aaa authentication login CONSOLE local
    So if Tacacs fail local will take over.

  • Securely backing up config for ASA

    How do you usually store the backup config for your ASA/PIX config so that it's easily accessible, and yet it's secure enough? Do you simply save it to a network drive? Is there a better way to do it? I just like to know the best practice out there. It's because if I save the backup config in a network drive, people may be able to get to it and look at the config file since it's not encrypted. Any recommendation is welcome. Thanks.

    We have our configs backed up automatically and they are stored in a database (with security). Why can't you save it to a network drive that has the appropriate permissions? You could also store them in an encrypted virtual drive using something like TrueCrypt.
    Hope that helps.

  • Using ACS with PIX/ASA

    Hi there,
    We have an implementation of Cisco Secure ACS 4.1.4 using RSA SecurID as its authentication source to provide role-based access control and command level authorisation.
    We have succesfully deployed this our routers/switches, and are now looking at configuring Cisco PIX/ASA devices to use ACS and have stubbled across issues.
    Config on PIX/ASA (note we actually have 4 ACS servers defined for resilience etc):
    aaa-server XXXXX protocol tacacs+
    accounting-mode simultaneous
    reactivation-mode depletion deadtime 1
    max-failed-attempts 1
    aaa-server XXXXX inside host <SERVER>
    key <SECRET>
    timeout 5
    aaa authentication telnet console XXXXX LOCAL
    aaa authentication enable console XXXXX LOCAL
    aaa authentication ssh console XXXXX LOCAL
    aaa authentication http console XXXXX LOCAL
    aaa authentication serial console XXXXX LOCAL
    aaa accounting command XXXXX
    aaa accounting telnet console XXXXX
    aaa accounting ssh console XXXXX
    aaa accounting enable console XXXXX
    aaa accounting serial console XXXXX
    aaa authorization command XXXXX LOCAL
    Problems:
    Enter PASSCODE is NOT displayed on first attempt to logon to the PIX/ASA because it does not attempt to communicate with ACS until username/pass is sent.
    Username with null password (e.g. CR) will correctly then display Enter PASSCODE prompt received from ACS.
    PIX/ASA does not attempt to authenticate against all configured TACACS+ servers in one go, instead it tries each sequentially per authentication attempt….e.g.
    1st Attempt = Server 1
    2nd Attempt = Server 2
    3rd Attempt = Server 3
    4th Attempt = Server 4
    This means that in total failure of ACS users will have to attempt authentication N+1 times before failing to LOCAL credentials depending on number of servers configured, this seems to be from setting "depletion deadtime 1" however the alternative is worse:
    With “depletion timed” configured, by the time the user has attempted authentication to servers 2,3 and 4 the hard coded 30 second timeout has likely elapsed and the first server has been re-enabled by the PIX for authentication attempts, as such it will never fail to local authentication locking the user out of the device, the PIX itself does warn of this with the following error:
    “WARNING: Fallback authentication is configured, but reactivation mode is set to
    timed. Multiple aaa servers may prevent the appliance from ever invoking the fallback auth
    mechanism.”
    The next issue is that of accounting.....AAA Accounting does not record “SHOW” commands or session accounting records (start/stop) or “ENABLE".
    The final issue is ASDM. We can login to ASDM successfully using ACS/RSA SecurID, however when a change is made to the configuration ASDM repeatedly sends the users logon credentials multiple times.
    As RSA SecurID token can only be used once this fails and locks the account.
    Any ideas on how to make two of Ciscos leading security products work together better?

    Just re-reading the PIX/ASA 7.2 command reference guide below:
    http://www.cisco.com/en/US/docs/security/asa/asa72/command/reference/crt_72.pdf
    It appears some of the above are known issues.
    PASSCODE issue, page 2-17 states:
    We recommend that you use the same username and password in the local database as the
    AAA server because the security appliance prompt does not give any indication which method is being used.
    Failure to LOCAL, page 2-42 states:
    You can have up to 15 server groups in single mode or 4 server groups per context in multiple mode. Each group can have up to 16 servers in single mode or 4 servers in multiple mode. When a user logs in, the servers are accessed one at a time starting with the first server you specify in the configuration, until a server responds.
    AAA Accounting, page 2-2 states:
    To send accounting messages to the TACACS+ accounting server when you enter any command other than show commands at the CLI, use the aaa accounting command command in global configuration mode.
    ASDM issue, page 2-17 states:
    HTTP management authentication does not support the SDI protocol for AAA server group
    So looks like all my issues are known "features" of PIX/ASA integration with ACS, any ideas of how to achieve a "slicker" integration?
    Is there a roadmap to improve this with later versions of the OS?
    Will the PIX/ASA code ever properly support the same features as IOS?
    Would it be better to look at using something like CSM instead of ASDM?

  • AAA problems PIX/ASA

    Hello
    I have a problem with authentication on my network. Here I have support level 2 and level 3.
    Level 2 support, has restricted access to some switches and routers, the firewalls they could only give "Show ", the problem is that this is not happening.
    I configured on the ACS command shell Authorization for the commands on switches and routers, for these users of level 2. and PIX / ASA shell commands, I set only the command Enable and Show.
    My problem is that even when the support level 2 tries to access PIX and ASA on my network, they use the authorization of routers and switches, they do not use the parameters that I set up the PIX and ASA for Shell.
    the only firewalls on my line is this Authorization below
    Authorization TACACS + aaa command LOCAL
    I have to configure anything else?
    I can not create command line only for Firewalls.
    I'm missing something? something missing?
    my firewall and IOS versions:

  • REMOVING IPSEC VPN CONFIG FROM PIX 6.3 FIREWALL

    Hey,
    we have pix 6.3 serving as internet firewall and we are int process of replacing it with new ASA Device. currently there are several site to site and remote vpn are configured for access purposes. 
    i tried to remove one site2site ipsec vpn from pix and it starts acting like a loop generating the same error with qty that processor got 100% CPU, couldn't logged in through normal ssh so i connected via console and place back the isakmp and crypto map commands back in and the error stops.
    My purpose of this question is that how can i remove vpn config from pix without generating any error is there any formal process or order of removing rules from pix or we can do it one by one no order is required.
    MY PROCESS OF REMOVING CONFIG:
    REMOVE THE ACCESS-LIST INSIDEOUT AND OUTSIDE IN COMMANDS 
    REMOVE THE OBJECTS AND OBJECTS GROUPS
    REMOVE THE VPN DEFINED ACCESS-LIST FOR INTERESTING TRAFFIC
    REMOVE CRYPTO MAP TRANSFORM-SET
    REMOVE ISAKMP-POLICY
    REMOVE CRYPTO MAP 
    WE DO USE ISAKMP SHARED KAY MECHANISM "I DID NOT REMOVE THAT "
    BUT AS SOON AS I REMOVE THE CRYPTO MAP FROM THE PIX I GOT THIS ERROR
    IPSEC(crypto_map_check): crypto map XYZ 20 incomplete.  No peer or access-list specified.
    20 IS THE ISAKMP POLICY NUMBER & Peer and Access-list was removed from pix
    any help would great
    regards

    Hi
    You could do either of 2 things.
    1) Enable NAT-Traversal on your ASA
    2) Add the following on your pix :
    fixup protocol esp-ike
    This allows one IPSEC connection to run through PAT.

  • "authorization exec" on PIX/ASA

    I'm seeing posts that hit all around my questions, and based on my intereptation of the documentation it appears that there is no "shell exec" authorization available to the PIX when configured to use a TACACS+ server for authentication. Is this true? The problem I have is that whenever I create a new username in SecureACS that user (w/default settings) is immediately able to login and get a shell prompt on our PIX and ASA devices. I see no means (other than a NAR) that will restrict the user from getting a shell. Am I missing something?
    I know I can do command authorization, but exec authorization seems to be a glaringly missing feature.
    For example, how do I allow a user to be authenticated for a WebVPN session (via TACACS), but not be allowed to login via SSH for administration?

    Hi,
    Yes, you are correct, currently there is no shell exec on pix/asa, that we have on all routers and switches. In case you are using TACACS+ for WebVPN, and dont want to allow them to login via SSH for administration, probably you can try the same login that is used in Access Points,
    Actually what happens in, if you have ever came across mac authentication on AP's. On local database of AP, user accounts are created using the mac address as username/password. But interesting thing is, they have *autocommand* in the end i.e.
    username xxxx password xxxx
    username xxxx autocommand exit
    So what actually happens here is, though user is authenticated, but if that user tried to use their MAC address to log into AP [If they think they are cleaver enough], then they will login in and will be kicked out automatically.
    Havnt tried this yet, probably we can use same logic with PIX/ASA. Making use of "auto command" under "TACACS+ Settings" for a group/user.
    Probably, I'll do a small re-create of it and will let you know, you try at your end.

    Prem

  • PIX, ASA or VPN concentrator & dynamic VPN

    Hi all,
    I need help what to use and how to do next.
    What we need is to create remote VPN for many users so that every user is member of more than one group and every group is linked to predefined set of rules, for instance you can access this IPs, ports and so on.
    How to do that dynamically? Is it possible to do that with one certificate?
    Other question is what to use? ..PIX, ASA, VPN concentrator ?
    BR
    jl

    The PIX and VPNC are both end of sale products now and unless you already have them your only choice is IOS or ASA. Of those two the ASA is the Cisco preffered platform for Remote Access VPNs.
    You can map users to groups using Active Directory OUs, let them select a group at logon, have different logon URLs per group etc. However as far as I know this is not possible:
    "every user is member of more than one group "
    Some links:
    http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a008089149d.shtml
    http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a00808bd83d.shtml
    With remote access IPSEC VPNs you can either define the groups on the ASA or externally on the ACS Server.

  • PIX/ASA Failover conditions

    I have a asa cluster in active/standby mode with lan cable connected for stateful failover. I want to know about the condtions when the box fails over to the other. One parameter should be the hello timers going between the failover interfaces.
    Does this failover happen when the inside or outside interface of the primary asa goes down.

    What type of Firewall is it? What version.
    For PIX 7.2 for example I would look at the configuration guide
    http://www.cisco.com/en/US/docs/security/asa/asa72/configuration/guide/failover.html
    In particular look at the section entitled "Failover Actions" for active/standby. These is a nice table of failover conditions there.

  • Automatic jump to privilege level 15 in PIX/ASA

    Hi, with IOS router and switch I'm able to authorize the user to jump automatically to the correct privilege level in login phase, as configured in authorization privilege field in ACS.
    With PIX/ASA the jump does not run: why ?
    thank you in advance
    RS

    I have to disagree here.
    It's not a security feature. The privilege level feature was never properly implemented in the PIX/ASA. You may call it a bug
    I would have been a security feature if it would be implemented on all privilege levels besides level 15, so that users were prevented from going directly to priv. exec mode. But on the ASA/PIX, it does not work for any level (as the feature was not implemented).

  • New Type of Firewall Config (for me)

    OK - this is a different type of config for me so I am reaching out for  some advise / help.  I manage many cisco asa 5520's and I am in the  process of converting one asa from a block of 30 outside addresses of to  a 50 Meg Cox cable modem with a block of 30 cidr addresses.
    Normally  I would just reference an outside address and bingo, things would work  right.  In this case I found out so far that I could only get internet  access through this cable modem by setting up the outside interface of  the asa with dhcp - then it grabbed a public wan address, added a route  to the asa 5520 and then I had internet access out through the cable  modem.
    My question / problem / nuance to me is when I reference /  assign  one of our cidr addresses to a device (like a server) and that  is natted from the dmz to the outside address I don't get access to the  device.
    I'm thinking I have to do something special to set up  these cidr addresses but having never done this before I am reaching out  for some advise.
    my outside dhcp assigned wan address is 70.168.x.1xx with a gateway of 70.168.x.1
    The cidr block I have been assigned from the cable company is
    184.185.x.x/27
    The  cable company also has suggested a default gateway address withing the  cidr block and a first useable and last useable address.
    I must say that I usually look to over complicate things by thinking things are more difficult than they really are.
    Can  anyone get me pointed in the right direction so I know how to assign  these cidr addresses and have then accessable from the outside???
    Thanks in advance
    Paul

    Hi,
    So from what I understand you should have your own public IP address range of /27 usable through your current connection. Yet it only works with setting the ASA outside to use DHCP and doesnt work when you staticly assign an IP address from the /27 address range and set the default route.
    If the above is the case I'm kinda wondering why you are even getting IP address with DHCP from the ISP if you are supposed to have your own public address block.
    You sure the ISP has its side configured correctly?

  • Pix/Asa OSPF passive interface

    Hi.
    I am going to have an OSPF process for two internal interfaces. But I also have one external interface where I do not want any OSPF traffic going out. I have not so far found any OSPF PASSIVE INTERFACE type of commands om PIX/ASA. Is there any one out there who knows if there is one command like that or how one can stop OSPF packet from going out. I presume that an outgoing access-list will not stop this traffic.
    Regards Bjorn

    Hi,
    Don't define external interface as partecipating to OSPF process.
    That is you have to define the two interface partecipating to OSPF process:
    view: "Enabling OSPF ". Here is the link:http://www.cisco.com/en/US/docs/security/asa/asa70/configuration/guide/ip.html#wp1041629.
