ACS/ASA authentication for vpn access vs. console management access

I have an ACS 4.2 Server and an ASA 5540. I have setup AnyConnect SSL VPN on the ASA and want to authenticate users using AAA tacacs+ authentication with the ACS and an external Windows AD database. I have done this successfully. I also want to use the ACS for authenticating SSH management sessions into the ASA. I have setup a group in AD and on the ACS called VPNUSERS and NETADMINS. The problem is, I want the VPN users to ONLY be able to authenticate for VPN but not have access to logging into the ASA CLI or ASDM. The NETADMINS should be able to do both. The question I have is how do I setup the VPNUSER group in ACS to have access to connect to the ASA for VPN but not for the management console? It seems that if they can authenticate for vpn, they can also ssh the firewall which is what I want to prevent.

Try using Network Access Restrictions (NAR)where you can restrict the administrative access on per device or on NDG basis.
By default user accounts from external database such as AD in ACS will get authenticated through telnet on network device or a AAA client which can be restricted by enabling NAR in ACS.
In your case it should be VPNUSERS group in ACS.

Recommended ASA software for VPN ?

Hello -
We’re in the process of migrating our legacy VPN concentrators over to a pair of ASA5540s. The VPN connections we use today are L2L, RA, & easy VPN. I don’t want to jump up to 8.3 or higher just yet, due to the differences in the NAT, group-objects and ACL policies.
Would it be recommended to use an 8.2 code as standard for VPN endpoints?
Thanks -
John

You can very well use 8.2 .Right 8.3 onwards changes are there the way we configure NAT but its not very complicated to ignore latest version just because of NAT.
Just have a look on the link-http://www.cisco.com/en/US/docs/security/asa/asa83/release/notes/asarn83.html.
You might miss some new aded features but if not using those then its all right to go for 8.2
Thanks

ASA 5505 IPSEC VPN connected but can't access to LAN

ASA : 8.2.5
ASDM: 6.4.5
LAN: 10.1.0.0/22
VPN Pool: 172.16.10.0/24
Hi, we purcahsed a new ASA 5505 and try to setup IPSEC VPN via ASDM; i just simply run the Wizards, setup vpnpool, split tunnelling,etc.
I can connect to the ASA by using cisco VPN client and internet works fine on the local PC, but it cannot access to the LAN (can't ping. can't remote desktop). I tried the same thing on our Production ASA(those have both Remote VPN and Site-to-site VPN working), the new profile i created worked fine.
Below is my configure, do I mis-configure anything?

I change a Machine's gateway to this ASA and capture again, now we can see some reply.
All ohter PCs and switches gateway are point to another ASA, maybe that's the reason why i didn't work?
what's the recommanded way to make our LAN to have two 2 gateways(for load balance or backup router, etc)?
add two gateways to all PCs and swtichwes?

Trying to use DS 6.2 w/ Cisco ASA 5540 for VPN Auth

Hello all,
I'm trying to connect our Cisco ASA 5540 with LDAP authentication to our DSEE 6.2 directory. The authentication is failing and this line in the debug output from the firewall is really getting to me: "No results returned for iPlanet global password policy".
Their authentication process is two-steps.. It binds with a service account, searches on the "naming attribute" (in our case uid), grabs the DN of the user, and unbinds. With step 2, it binds to the directory with the DN it found when searching, and the password the user supplied. If the second bind is successful, then the firewall lets them on the VPN.
When the firewall binds with the service account, it successfully finds the user's DN and disconnects, so I know my ACI is working correctly there. It just seems to fail when trying to re-bind with the user's DN...
We opened a TAC case with Cisco, and this is their response:
The DN configured on the security appliance to access a Sun directory server must be able to access the default password policy on that server. We recommend using the directory administrator, or a user with directory administrator privileges, as the DN. Alternatively, you can place an ACI on the default password policy.
I refuse to let a poorly written application or appliance bind as cn=Directory Administrator!
I tried putting an ACI on the default password policy located at cn=Password Policy,cn=config , but that doesn't seem to make any difference to the ASA.. My best guess is that it's looking somewhere else for the password policy... did it used to be located elsewhere in iPlanet? Has anyone made this work before with a Cisco ASA?

My network admin and I ended up solving this problem by sheer dumb luck. In the ASA config, you tell it what kind of LDAP server it's connecting to. In one set of docs, it had the available options as microsoft, sun, or generic. In another set of docs, we found that openldap was also an acceptable option.
I'm guessing the ASA is thinking the "sun" option is connecting to the old Netscape Directory Server. Changing the "server type" to openldap made it work immediately. It also does not look like it's trying to look at the LDAP server's password policy now either.

Can I use ISE IPN without posture for VPN with Base license only?

I'm looking at ISE licensing, and both Base and Advanced licenses have VPN listed. I could not find any document that provides guideline for VPN implementation using ISE Base license only.
1. Can I use ISE IPN (Inline Posture Node) functionality without posture assessment with ISE Base license only? (I know it has to be ISE hardware appliance, and I know that Posture assessment requires ISE Advanced license.)
2. Do I have to use IPN for VPN deployment using ISE as the Radius server?
3. If I do not have to use IPN for VPN, can I use ISE for Authentication and Authorization in the same way as I use ACS?
Thanks,
Val Rodionov

Val,
There is no need to consider IPN if you are not using posturing. You can use ISE much like ACS for radius authentication for vpn users.
If posturing is down the road and your hope is to have an architecture in place and license later, then I am sure that you can use the ipn with base licensing, however I would strongle recommend working with the PDI (for partners) for help and confirmation.
Thanks,
Tarik Admani

Cisco ASA 5505 L2TP VPN cannot access internal network

Hi,
I'm trying to configure Cisco L2TP VPN to my office. After successful connection I cannot access to internal network.
Can you jhelp me to find out the issue?
I have Cisco ASA:

Thanks for your help.

You have to test it with "real" traffic to 192.168.1.2 and if you use ping, you have to add icmp-inspection:
policy-map global_policy
class inspection_default
inspect icmp

AAA authentication for networking devices using ACS 4.1 SE

Hi!!!
I want to perform AAA authentication for networking devices using ACS 4.1 SE.
I do have Cisco 4500, 6500,2960, 3750, 3560, ASA, CSMARS, routers (2821) etc in my network. I want to have radius based authentication for the same.
I want telnet, ssh has,console attempt to be verified by radius server & if ACS goes down then it will be via local enable passwordf.
For all users i need to have different privilege levels based upon which access will be granted.
could u plz send me the config that is required to be done in the active devices as well as ACS!!!!

Pradeep,
Are you planning MAC authentication for some users while using EAP for others?
For MAC authentication, just use the following in your AP.
aaa authentication login mac_methods group radius
In your AP, select the radius server for mac authentication. You must have already defined your ACS as a radius server.
In your SSID configuration, under client authentication settings,
check "open authentication" and also select "MAC Authentication" from the drop-down list.
If you want both MAC or EAP, then select "MAC Authentication or EAP" from the dropdown.
Define the mac address as the username and password in ACS. Make sure the format of the mac is without any spaces.
You will not need to change anything in XP.
NOTE: XP normally does not require user authentication if machine has already authenticated but it might behave differently. If it does, I can let you know the registry settings to force the behaviour change.

ASA - cut through proxy authentication for RDP?

I know how to set this up on a router (dynamic access-list - lock and key)... But, I'm having trouble understanding how to setup OUTSIDE to INSIDE cut through proxy authentication for RDP.
OUTSIDE to INSIDE RDP is currently working.
I have 2 servers I want RDP open for..
[*]OUTSIDE 1.1.1.1 to INSIDE 10.10.70.100
[*]OUTSIDE 1.1.1.2 to INSIDE 10.10.50.200
What's required for OUTSIDE users to authenticate on the ASA before allowing port 3389 opens? I was hoping for is a way to SSH into this ASA, login with a special user, then have the ASA add a dynamic ACE on the OUTSISE interface to open 3389 for a designated time limit. Is this possible?
Here is my current config.

You're running ASA 8.2(5). In 8.4(2) Cisco added support for what they call Identity Firewall rules. That is, you can make access-lists entries specific to users (or object groups containing users).
There's an overview document on this posted here. It's a bit dated but I believe the only change is that Cisco is now preferring use of the more current Context Directory Agent (CDA) - a free VM they provide - vs. the deprecated AD agent (software service that runs on your DC).

AAA Authentication for Traffic Passing through ASA

I am setting up AAA authentication for traffic that will pass through my ASA. I am having difficulty enabling 'aaa authentication secure-http-client'. Without secure communications enabled access functions as expected. When I enable access, I get prompted for a username/password. The username/password is entered. Authentication passes (show uauth). The requested page (http://www.cisco.com) switches to https://x.x.x.x (a resolved IP address for the site). Eventually (5 seconds), I am asked to accept or deny a certificated. Interestingly, the certificate is for the ASA and not the requested site (http://www.cisco.com).
Am I missing something?
firewall# show run aaa
aaa authentication http console TACACS+ LOCAL
aaa authentication telnet console TACACS+ LOCAL
aaa authentication serial console TACACS+ LOCAL
aaa authentication ssh console TACACS+ LOCAL
aaa authentication enable console TACACS+ LOCAL
aaa authentication match guestnetwork_access guestnetwork RADIUS
aaa authentication secure-http-client
firewall# show access-li guestnetwork_access
access-list guestnetwork_access; 2 elements
access-list guestnetwork_access line 1 extended deny udp 10.255.255.0 255.255.255.0 any eq domain (hitcnt=33)
access-list guestnetwork_access line 2 extended permit ip 10.255.255.0 255.255.255.0 any (hitcnt=412)
firewall# show run aaa-s

your definition for the aaa-server is different to the aaa authentication server-group

ACS with RSA for privilege level 'enable' authentication

Has anyone experienced problems with privilege level "Enable" password authentication via ACS using RSA two factor authentication? We have recently deployed ACS and use RSA two factor authentication for the telnet connection without any problems. When configuring the networking device and ACS to use RSA for the privelledge level authentication "enable" this fails. We get prompted to enter the token code and the RSA server indicates that authentication is succesful however the network device (ASA or switch) seems to reject it.
Are there any tricks to this?
Thanks in advance!

David
Like Collin the first thing that I think of is that you can not use the same token code to authenticate enable mode that was used to authenticate user mode. Beyond that I am not aware of things that should prevent this working. Are you sure that the ACS authentication server is configured to allow that user access to privilege mode?
Perhaps it would be helpful if you would post the config (especially all the aaa related parts) of a device that is having that problem. And it might help find the issue if you would run debug for authentication, try to login to enable mode, and post the output.

VPN session established but cannot access trusted LAN segment on the ASA

Just a roundup of my Cisco ASA configuration...
1) Configure remote access IPSec VPN
2) Group Policies - vpntesting
3) AES256 SHA DH group 5
4) Configure local user vpntesting
5) Configure dhcp pool - 10.27.165.2 to 10.27.165.128 mask /24
6) open access on outside interface
7) IKE group - vpntesting
A) Did I miss anything?
B) For example, there is a LAN segment - 10.27.40.x/24 on the trusted leg of the Cisco ASA but I can't access it. Do I need to create access lists to allow my VPN session to access the trust LANs?
C) Any good guide for configuring remote access VPN using ASDM?

I have couple of issues with my EasyVPN server and Cisco VPN Client on Win7.
1: Sometimes, clients are connected, connection shows established but no traffic or pings can be made to corp network. I might have to do with NAT settings to except VPN traffic from being NATed.
2: VPN Clients don't pick the same IP address from local address pool even though I specified "RECYLE" option.
I would apprecaite if you look at my configuration and advise any mis-config or anything that needs to be corrected.
Thank you so much.

We are planning to implement dual factor authentication for Anyconnect VPN.
The end users will be authenticated using domain name in machine certificates and username password with
ISE used as radius server.
We have the following approaches to achieve this :-
1. Use primary and secondary authentication with user credentials as primary authentication
and CN field of the certificate as secondary authentication.However this option prompts users for password for
both the fields while we want the machine certificate to authenticate itself without a password.
2. Second approach is to authenticate using user credentials and authorize the user to access the network if
the machine certificate has a domain name in CN field which we are able to validate from the AD using
Dynamic Access Policy.
We are looking forward for discussions on the above approaches and are open to any other
solution.

Hi Umahar,
Not sure I understood correct. You would like to authenticate the user using machine certificate for anyconnect and want to extract CN attribute the client's certificate and send it to the ISE server for further authenticate with AD. And also you don't want an additional password prompt to be produced to the user.
If my understanding is correct. Then user would get a prompt for the password atleast because in the machine certificate there won't be password, but to authenticate with RADIUS/TACACS , we need both username and password. So how will the user gets authenticated without password.
If you are looking a way to just see if the user is present under AD, not exactly and authentication then this might not be possible.

User Authentication for Internet access

Hi,
Is it possible to configure authentication for internal (LAN) users to Authenticate (local/RADIUS/LDAP) for any kind of internet access through the ISA550/570? (like cut-through authentication proxy in ASA.)
And Can the ISA550/570 act as a Web proxy?
Thanks in advance.

HI Sulu,
You can configure captive portal for internal LAN users to authenticate (local/Radius/LDAP) for internet
access through ISA500. (see attached screenshot)
ISA500 cannot act as a web proxy. what is your use case ?

Wei

Enable authentication for ASA

hi,
Im working on AAA authentication for an ASA (ASA 8.0(3) version) box thorough a TACACS+ server in ACS (4.2 version). The setup im working on includes several users in 3 classes: senior (privilege level 15), junior (privilege level 7) and monitoring (privilege level 0), user authentication and command authorization is working fine, however im having problems with enable authentication.
When an user of junior class try to authenticate the enable password the authentication fails, according to the ACS's log "Tacacs+ enable privilege too low", however the privilege level in ACS for this class is set to level 7. Checking with a sniffer i have find out that the TACACS+ message for authentication sent by ASA is setting the privilege level as level 15, as you can see in the attached screenshot. Of course if the ASA is trying to authenticate enable for a level 15, the authentication will fail according to user's current level.I have local authentication configured in the ASA and it works fine including enable authentication.
Anyone have had any issue with this or have any idea how resolve this issue?
thanks all for your replies.

Seems like you might be hitting bug CSCsh66748.
Hope you have tried "enable " command to enter enable mode for specific users.
BTW why are you using different privileges for enable when you already have command authorization in place.
