Which protocol is used by RADIUS?

Which protocol is used by RADIUS? User Datagram Protocol (UDP) Communication between a network access server (NAS) and a RADIUS server is based on the User Datagram Protocol (UDP). Is RADIUS an open protocol? Features

Which protocol is used by RADIUS?

User Datagram Protocol (UDP)
Communication between a network access server (NAS) and a RADIUS server is based on the User Datagram Protocol (UDP).

Is RADIUS an open protocol?

Features – Some of the features of RADIUS are: Open standard protocol for AAA framework i.e it can use between any vendor device and Cisco ACS server. It uses UDP as a transmission protocol. It uses UDP port number 1812 for authentication and authorization and 1813 for accounting.

What are the 3 A’s in the AAA protocol?

AAA stands for authentication, authorization, and accounting. AAA is a framework for intelligently controlling access to computer resources, enforcing policies, auditing usage, and providing the information necessary to bill for services.

Is RADIUS UDP or TCP?

Diameter uses SCTP or TCP while RADIUS typically uses UDP as the transport layer. As of 2012, RADIUS can also use TCP as the transport layer with TLS for security.

What is the difference between Tacacs and RADIUS?

RADIUS was designed to authenticate and log remote network users, while TACACS+ is most commonly used for administrator access to network devices like routers and switches. Traditionally authorized users provide a username and password to verify their identity for both RADIUS and TACACS+.

What are the three characteristics of RADIUS?

What are three characteristics of RADIUS? Answers B, C, and E are correct. RADIUS is an open standard developed by the IETF; it uses UDP/IP and is only able to encrypt passwords. Answers A and D describe TACACS+; it is Cisco proprietary, uses TCP/IP, and encrypts all the data.

Which protocols are implementations of AAA?

TACACS+ and RADIUS are the predominant security server protocols used for AAA with network access servers, routers, and firewalls. These protocols are used to communicate access control information between the security server and the network equipment.

What are three characteristics of the RADIUS protocol?

What are the major activities of AAA?

Authentication, authorization, and accounting (AAA) is a term for a framework for intelligently controlling access to computer resources, enforcing policies, auditing usage, and providing the information necessary to bill for services.

What are the components of the RADIUS protocol?

RADIUS is an access server that using the AAA protocol. It is a system following a pattern of distributed security, securing remote access to networks and network services against unauthorized access. It comprises of three components: A protocol with a frame format that utilizes User Datagram Protocol (UDP)/IP. A server.

Who is the creator of the AAA protocol radius?

RADIUS (Remote Authentication Dial-in User Service) is all-vendor supported AAA protocol. RADIUS was first developed by Livingston Enterprises Inc in 1991, which later merged with Alcatel Lucent. RADIUS later became an Internet Engineering Task Force (IETF) standard.

What do you need to know about AAA protocols?

They need to check who they are, what are they allowed for and what did they do. These three questions are the main explanation of AAA (Authentication, Authorization, Accounting). There are some protocols are used for this purposes. The two common ones are TACACS+ and RADIUS. In this lesson we will see, TACACS vs RADIUS.

What does radius stand for in network access?

RADIUS is a protocol for carrying authentication, authorization, and configuration information between a Network Access Server which desires to authenticate its links and a shared Authentication Server. RADIUS stands for Remote Authentication Dial In User Service. RADIUS is an AAA protocol for applications such as Network Access or IP Mobility
