The Publishing Rule from the previous article can be used without reconfiguration. You can then use this Listener in a Publishing Rule. Now select “RADIUS OTP” authentication in the Authentication settings tab. Locate and open the “Web Listener” dialog at the bottom and right click the Listener that you created in the previous article. Select “Toolbox” and then click on “Network Objects” in the TMG Console. I continue by reconfiguring the Listener on the TMG from the previous article. Also be aware, that if your RADIUS server uses a port other than 1812, you will have to allow it independently. Locate “Configure Authentication Server settings”Ī new window will pop up, click “add” and enter the relevant information (IP, Shared Secret And Port). We will do this by defining a RADIUS server with TMG. But first we have to configure TMG to query an authentication server.

In this post, I will describe how to configure the Listener to use OTP and PKI pre-authentication. In my previous article, I already explained how to configure Kerberos Constrained Delegation in a Publishing rule. For working with OTP credentials, Kerberos Constrained Delegation and Protocol Transition is required.

How can a security minded administrator make sure that users would enter only OTP credentials when accessing backend HTTP/HTTPS based services? It’s obvious that you can’t achieve this by using Basic Credential Delegation which means passing username and password from the TMG server to the backend server. Such a machine could run key logging malware that collects static passwords and other information that could be used in a subsequent attack. You can probably imagine the variety of threats in those environments. This is especially problematic in a “hostile” environment such as internet cafes or the “mother-in-law” computer (I heard this term at a Microsoft presentation for UAG and I just had to use it). Why is this not good? You expose critical security information (Domain username and password, which are static) when a user has to enter Domain credentials on a machine that doesn’t belong to your corporate network.

So how is the end-user experience when multiple pre-authentication methods are used without Credential Delegation? If you were to use RADIUS One-Time Password pre-authentication on the TMG Listener, a user would have to enter his OTP credentials first and then provide his Windows credentials for access to the web server. how you can authenticate users with one method and then pass the credentials to the backend using Kerberos. I will describe how Protocol Transition works with TMG, i.e. In the example here, we will use a one-time password solution that provides a simple, user friendly and very secure solution that is ideal for securing access to corporate resources when used with Microsoft (TMG) and Kerberos Constrained Delegation. Users can pre-authenticate using Windows Active Directory authentication, RADIUS OTP authentication, Certificate authentication or LDAP authentication, and even with PKI certificates. Today, I will discuss pre-authentication methods that are not based on Active Directory. In the previous article of this Kerberos Delegation series, you learned how to configure Kerberos Constrained Delegation. This article explains how to configure One-Time Password pre-authentication. What strikes me here is that it sees the protocol as Unidentified IP Traffic, whilst I've explicitly defined the protocol.Access to corporate resources from external computers requires secure authentication methods. Network Rule Name: None - Route implied (Local Host traffic) The test denies the traffic as shown below: When I go to Troubleshooting and the Traffic Simulator, my simulation scenario is Non-Web access from the IP Address of my Zabbix server, to the IP Address of my Forefront server on port 10050, TCP. Under the Protocols tab, I've selected Selected protocols and added the Zabbix-Agent protocol that I added earlier. Then I created a new Access Rule, called Zabbix. In my Forefront manager, I've added a protocol called Zabbix-Agent, it has TCP 10050, Inbound and UDP 10050, Receive Send. I cannot connect to the the Forefront machine via Telnet on port 10050, which is what is needed for the Zabbix Agent to work.

All the servers except the Forefront one are communicating with the Zabbix server. So far everything is going well, the agent is installed on all the servers.

I'm setting up Zabbix for monitoring on our network.
