! Specify a AAA server name (NY_AAA) and which protocol to use (Radius or TACACS+)ĪSA(config)# aaa-server NY_AAA protocol tacacs+ The ASA firewall (Arrow 2) will request Authentication permission from the AAA server in order to prompt the admin user for Username/Password credentials.Īfter the Admin successfully enters his/her credentials, the AAA server will give the permission to the Firewall to allow the user in. Referring to the figure above, the firewall administrator (Admin) requests firewall access (serial console, SSH, or Telnet) (Arrow 1) for managing the appliance. Assume also that the AAA server is located on our internal LAN network with address 10.1.1.1 On the AAA server, we have configured a username/password account that the firewall administrators will use to authenticate. The replacement option is Cisco ISE (Identity Services Engine) but the concepts of authenticating via TACACS+ are the same. NOTE: Cisco ACS has reached end-of-life as a product. In this example we assume that we have already installed and configured a AAA server (e.g Cisco ACS or ISE) running the TACACS+ authentication protocol.
Authentication configuration example using TACACS+

We will see a configuration example for the first type (authentication for accessing the security appliance for management using Serial Console, SSH, and Telnet access). User Authentication for VPN tunnel access ( IPsec or SSL VPN). This is also called “cut-through proxy” and is used to authenticate users for accessing Telnet, FTP, HTTP, and HTTPs services located in the network through the firewall.ģ. User Authentication for accessing services through the security appliance. User Authentication for accessing the security appliance itself.Ģ. Three types of Authentication are available for Cisco ASA firewalls:ġ. Types of Authentication supported on ASA appliances

In this post we will see examples how to configure all AAA elements on ASA (that is Authentication, Authorization and Accounting) using TACACS+ and also explain how to configure authentication using the RADIUS protocol. AAA is a mechanism that is used to tell the firewall appliance (or any networking appliance) who the user is (Authentication), what actions the user is authorized to perform on the network (Authorization), and what the user did on the network after connecting (Accounting).
