ACS 3.3 Config Command Authorization

Hi,
I want to allow an user only to add/remove routes on a router. The shell command authorization works fine. But when the user is in config mode, he can start any command!
The debug says:
1w2d: AAA/AUTHOR: config command authorization not enabled
How can I enable this and how/where can I configure it on the ACS?
Thanks in advance

On ACs just allow the user to enter the "route" command like you have any other shell command they're allowed to do.
On the router/NAS, you have to tell it specifically that you want authorization for config commands with the following:
aaa authorization config-commands
Note that the format of this command changes slightly on different IOS versions, but if you do "aaa authorization ?" you'll be able to figure it out.

3640 - AAA/AUTHOR: config command authorization not enabled

Hello, I have a 3640 router with c3640-ik9o3sw6-mz.122-8.T.bin version but when I try to validate the username and password with a radius server, the debbug message is "AAA/AUTHOR: config command authorization not enabled" and I'm sure that the radius validates the user and the packet arrive to the router.
I've tried to update the IOS with c3640-ik9o3s-mz.122-46a.bin and I can validate but I cannot use "crypto isakmp client configuration group mygroup" to configure Easy VPN server.
I attach you the files with config and logs.
Thanks you in advance.

Yep! I'm really running 12.1!
I'm receiving the message once i include "aaa authorization exec default group radius local if-authenticated" in the config.
Login is successful, however authorization does not allow me to go directly into enable mode. If I take the aaa authorization line out I can login to user mode and then use the enable password to move forward but that is not what I wish to achieve.
sh run | i aaa
aaa new-model
aaa authentication attempts login 5
aaa authentication banner ^C
aaa authentication fail-message ^C
aaa authentication login My-RADIUS group radius local
aaa accounting exec My-RADIUS start-stop group radius
aaa session-id common
Is there somewhere specific I was suppose to configure the aaa authorization enabled, because I'm not seeing it.
Let me know what other thoughts you may have.
Thanks

Config commands authorization on ASA

Hi, is there a way to control the config commands with tacacs+ authorization ?
When I enable the configure command, in ACS shell coomand authorization set, all other config commands are enabled.
In IOS there's the "aaa authorization config-commands", how to with ASA ?

Please check this link that explains about command authorization on ASA.
these commands are required on ASA/PIX/FWSM in order to implement command authorization through an ACS server:
aaa-server authserver protocol tacacs+
aaa-server authserver host 10.1.1.1
aaa authorization command authserver

Nexus, command authorization using TACACS.

Hello.
Can someone provide a sample configuration to use Cisco Secure ACS 4.2 to enable command authorization using TACACS.
Thanks.
Regards.
Andrea

Hi Andrea,
We've moved onto ACS 5.3 now - but we had our Nexus 5520's running against our old ACS 4.2 before that - so I've picked out the relevant bits of the config below:
username admin password role network-admin ; local admin user
feature tacacs+ ; enable the tacacs feature
tacacs-server host key ; define key for tacacs server
aaa group server tacacs+ tacacs ; create group called 'tacacs'
    server ;define tacacs server IP
    use-vrf management ; tell it to use the default 'management' vrf to send the tacacs requests
    source-interface mgmt0 ; ...and send them from the mgmt interface
aaa authentication login default group tacacs ; use tacacs for login auth
aaa authentication login console group tacacs ; use tacacs for console login auth
aaa authorization config-commands default group tacacs local ; use tacacs for config command authorization
aaa authorization commands default group tacacs local ; use tacacs for normal command authorization
aaa accounting default group tacacs ; send accounting records to tacacs
Hope that works for you!
(That can change a bit when you move to ACS 5.x - as we've chosen not to do complex command auth (using shell profiles only) so instead you pass back the nexus role to the 5k - and it does the command auth (network-admin vs network-operator) based on that - so you just don't configure aaa command authorization on the 5k)

Command Authorization Config best practice using ACS

Hi
Is there any best practices for configuring Command authorization (for router/switch/asa) in CS-ACS? To be specific, is there any best practices to configure authorization for a set of commands allowed for L1,L2,L3 support levels?
Regards
V Vinodh.

Vinodh,
The main thing here is to ensure that we have backup/fall-back method configured for command authorization, inorder to avoid lockout situation or do wr mem once you are sure configs are working fine.

ACS 5.1 command authorization in config mode

Hello all,
I have setup an ACS 5.1 system and a Cisco 3560 as test device. On the ACS system I have defined a user that will have limited access to Cisco CLI commands (privilege 15 through Shell Profile and limited commands through Command Sets). While this is working great for commands run under enable mode (meaning that the authorization denied the commands that I've specified in the Command Sets), it seems that it's not working under configure mode (e.g. I have denied commands like "router ospf" , "router bgp" , but the user can still apply them).
Before I've search this forum and found 2 posts:
https://supportforums.cisco.com/thread/2041611
https://supportforums.cisco.com/message/3057298
that suggest to have the AAA configured with:
aaa authorization config-commands
I already have this command and it still doesn't work. Actually my entire AAA config looks like this:
aaa new-model
aaa authentication login default group tacacs+ local
aaa authentication enable default group tacacs+ enable
aaa authorization config-commands
aaa authorization exec default group tacacs+ local
aaa authorization commands 1 default group tacacs+ local
aaa authorization commands 15 default group tacacs+ local
Did I miss something? Do you have any suggestion for me?
Thank you!
Calin

can you run a "debug aaa authorization" to see what happens?

Cisco Secure ACS 4.2 - Group Setup w/Shell Command Authorization Sets

Hello All,
I am trying to create a user so that I can provide him only to run commands that I have designated them to run within my "Shell Command Authorization Set". This seems to work great, however I cannot find anywhere I can "hide" commands they do not have access to. For instance, once the user is logged into the switch they can do a show ? and get a list of commands. I would like to know if there is an option to only display commands the user has access to in ACS.
My Steps:
Created a user in ACS
Shared Profile Components
Create Shell command Autorization Set - "ReadOnly"
Unmatched Commands - Deny
Unchecked - Permit Unmatched Arg
Commands Added
permit interface
permit vlan
permit snmp contact
permit power inline
permit version
permit switch
permit controllers utilization
permit env all
permit snmp location
permit ip http server status
permit logging
Created a group - "GroupTest" with the following
Confirgured - Network Access Restrictions (NAR)
Max Sessions - Unlimited
Enable Options - No Enable Privilege
TACACS+ Settings
Shell (exec)
Priviledge level is check with 1 as the assigned level
Shell Command Authorization Set
"ReadOnly" - Assign a Shell Command Authorization Set for any network device
I have configured following on my Router/Switch
aaa authorization config-commands
aaa authorization commands 1 default group tacacs+ if-authenticated
privilege exec level 1 show log
I have attached below the documention I have gone over.

"you are testing with privilege level 15 or below 15. Because when you are using below 15 level user, first it will check local command authorization set. For example if you want to execute sh runn command with level 5 user, first it will check local command set. If the sh runn command exits in local command set then it will send request to ACS. If it is not in the command set, it won't send request to ACS. That's why you don't see debug. For 15 level users it will directly send request to ACS. Configure command set locally and try it should work.
Correct me if I am wrong."

ACS shell command authorization help

Hello,
I wanted to only allow users to use interface command. But when I permit config terminal in ACS shell command set, all the commands are allowed. How can I limited the users to only have the permission for interfacce command?
Thanks

Two things could be wrong
1) You don't have the following command on your AAA Client:
aaa authorization config-commands
2) You have clicked the 'Unmatched Commands' = Permit radio option in ACS, have a look at:

Hi Jatin ,
first of all Thank you very much . It startted working after aaa authorization config-commands
here I was trying to achive one specfic thing .
I want to stop the following commands on ACS “switchport trunk allowed vlan 103” . I only want allow “add” after “vlan” and block rest all arguments
But even after setting the filter on ACS Still we are able to execute the command is there anything like we cannot control the commands after the sub commands
Also I am attaching the filter list along with this. Could you have look on this and let me know whether I have configured something wrongly. Other than this is there any work around is available to achieve this .
Thanks and Regards

ACS command authorization report in conf t mode

Hi, this is probably a quick one, but I couldnt find a solution so far.
We are using command authorization via ACS and are thus able to see (in case of any issues) who has entered which commands at which time on which device. But this only works until someone enters conf t mode. After that I am not getting log entries in the ACS (Version 5). I can see all show commands and who entered the configuration mode, but nothing after that. Config snippet:
aaa new-model
aaa authentication attempts login 5
aaa authentication login default group tacacs+ local line enable
aaa authentication enable default group tacacs+ enable
aaa authorization exec default group tacacs+ local
aaa authorization commands 1 default group tacacs+ local
aaa authorization commands 15 default group tacacs+ local
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+
aaa session-id common
My guess is that I allow all commands with that and thus no authorization is needed.
Any idea?
Thanks
Chris

ACS SE - Shell Command Authorization

Hi Sir,
I have deployed an ACS Solution Engine 4.1(1) Build 23 to provide AAA services for routers/switches login.
I'd like to create a user group that is restricted to only "show" commands when the users log in to the network devices.
I have done the following steps:
(1) Shared Profile Components -> Shell Command Authorization Sets
Added a new set. Call it NOC. I added the command "show". For "Unmatched Commands", I selected Deny. I also checked "Permit Unmatched Args".
(2) Group Setup.
Created a new group. Call it NOC. For Enable Options, I selected "Max Privilege for any AAA Client" value of "Level 7".
For TACACS+ Settings, I checked "Shell (exec)" and set "Privilege level" to 7.
For Shell Command Authorization Set, I selected NOC for "Assign a Shell Command Authorization Set for any network device".
(3) User Setup.
Created a new user. Call it noc. Assign it to group NOC. All parameters point to group setting.
(4) The AAA commands on the routers/switches are as follows:
aaa new-model
aaa authentication login default group tacacs+ local enable
aaa authorization exec default group tacacs+ local
aaa accounting exec default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
aaa accounting system default start-stop group tacacs+
ip tacacs source-interface Loopback0
tacacs-server host 10.10.10.10 key 0 tacacskey
When the noc logs in, he's given privilege level 7. True, he's limited to only "show" commands. He can't do "config t". However, he also can't do "show run". Is it normal? I'd need him to be able to do "show run". How to configure the ACS?
Thank you.
B.Rgds,
Lim TS

Hi Narayan,
Appreciate your detailed configuration steps.
My intention is to create a shell command authorization set that allows a user group to only perform "show" commands, including complete config of "sh run". This group is not allowed to configure anything.
See my original post for my configuration steps. I tied the group to the above authorization set and assigned it Level 7.
The outcome is, the user can do all "show" commands except "sh run". Of course, he is not authorized for configuration commands.
I came across the following link:
http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a00800949d5.shtml
Perhaps it explains the problem here. If I understand it correctly, a user can't see in the output of "sh run" what he can't configure at his privilege level or below.
The same issue happens when I configured the following:
no aaa new-model
username noc privilege 7 password test
privilege exec level 7 show
line vty 0 4
login local
The user "noc" can't do "sh run".
Thank you.
B.Rgds,

Problem - acs command authorization and web access control

Hi, I'm trying to add the control of some aironet 1310 bridges with a ACS 3.2 (tacacs+). I wanted to be able to do telnet command authorization restrictions trough shell command authorization sets and be able to give similar restrictive web access at the same time. I have it working if I permit some commands that are sent by the browser as "write memory quiet" and few other ones, but for it to work, I must give them limited users the privilege level 15 and by having the tacacs server authorizing the commands, it work for both, http and telnet. Where my problem begin is when I loose the connection with the ACS server, the user being already authenticated as level 15 user, the device become open to all commands; there is no more restriction applied by the ACS. Do anybody now a workaround.

It is already at local, that is just that the user already have a level 15 access and I used to control the commands through level settings before. So when I try it, my user that is localy level 5 is already recognized as a level 15 user from when it was authenticated through the ACS. If I could find a way to give web access to the 1310 at priv level 5 and still controlling the command set, it would be ok but as soon as I try to access a page that is not permitted other way than by the view level (i think it's level 1... or 0), I get a username password prompt with that line on the top of it:"level_15_or_view_access" and the only way I can access it is by entering a level 15 un/pass. I attached my 1310 aaa config
and here are the command set that work at level 15 to do a "shut" or "no shut" of the radio interface by the web interface:
configure
permit terminal
exit
permit Unmatched Args
interface
permit Dot11Radio0
no
permit shutdown
permit cca
ping
permit Unmatched Args
show
permit Unmatched Args
shutdown
permit Unmatched Args
telnet
permit Unmatched Args
write
permit memory quiet
Thanks for the help !
