Does ACS support RADIUS?
Does ACS support RADIUS?
RADIUS is defined in RFC 2138/2139. Cisco has developed a server application, CiscoSecure ACS, that supports both RADIUS and TACACS+. Figure 11-4 displays a typical RADIUS connection request (authentication).
Can a Cisco router be a Radius server?
In the Cisco implementation, RADIUS clients run on Cisco routers and send authentication requests to a central RADIUS server that contains all user authentication and network service access information. Cisco supports RADIUS under its authentication, authorization, and accounting (AAA) security paradigm.
Can a Cisco switch be a Radius server?
RADIUS is a distributed client/server system that secures networks against unauthorized access. RADIUS clients run on supported Cisco routers and switches.
What is Cisco ACS server?
Cisco Access Control Server (ACS) is an authentication, authorization, and accounting (AAA) platform that lets you centrally manage access to network resources for a variety of access types, devices, and user groups.
What is AAA Radius server?
Remote Authentication Dial-In User Service (RADIUS) is a networking protocol that provides centralized authentication, authorization, and accounting (AAA) management for users who connect and use a network service. A RADIUS server is usually a background process running on UNIX or Microsoft Windows.
Is Tacacs more secure than radius?
As TACACS+ uses TCP therefore more reliable than RADIUS. TACACS+ provides more control over the authorization of commands while in RADIUS, no external authorization of commands is supported. All the AAA packets are encrypted in TACACS+ while only the passwords are encrypted in RADIUS i.e more secure.
What version of radius is used with Cisco ASA?
The RADIUS server in this example is a Cisco Access Control Server (ACS) server, version 4.1 This configuration is performed with the Adaptive Security Device Manager (ASDM) 6.0 (2) on an ASA that runs software version 8.0 (2).
How do I test my radius configuration with ACS?
Verify your RADIUS configuration with the Test button on the AAA Server Groups configuration screen. Once you supply a username and password, this button allows you to send a test authentication request to the ACS server. Choose Configuration > Remote Access VPN > AAA Setup > AAA Server Groups.
How do I configure the ACS server to communicate with Asa?
Complete these steps in order to configure the ACS server to communicate with the ASA. Choose Network Configuration from the left menu of the ACS screen. Choose Add Entry under AAA Clients. In the Authenticate Using dropdown choose RADIUS (Cisco VPN 3000/ASA/PIX 7.x+).
What does radius stand for?
This document demonstrates how to configure the Cisco Adaptive Security Appliance (ASA) to use a Remote Authentication Dial-In User Service (RADIUS) server for authentication of WebVPN users.
