What does Radius mean?

RADIUS (Remote Authentication Dial In User Service) is a remote user dial-in authentication system. It is defined by RFC 2865 and RFC 2866 and is the most widely used AAA (Authentication, Authorization, Accounting) protocol. RADIUS is a C/S structure protocol. Its client is initially a NAS (Net Access Server) server. Any computer running RADIUS client software can become a RADIUS client. The RADIUS protocol authentication mechanism is flexible and can use various methods such as PAP, CHAP or Unix login authentication.

The principle of RADIUS authentication is as follows:

When a user attempts to connect to the network, the user's device (such as a computer or mobile phone) will send a connection request to the network, and this request will be sent to the NAS (Network Access Server). The NAS will encapsulate this request into a RADIUS Access-Request message and then send it to the RADIUS server.

On the RADIUS server, there will be a dedicated service to handle these requests. This service will decapsulate the Access-Request message, extract the username and password, and then perform authentication.

The RADIUS server will use the username and password to find the record in the database. If a matching record is found, the RADIUS server returns an Access-Accept message, allowing the user to connect to the network. If no matching record is found, or the password provided by the user is incorrect, the RADIUS server will return an Access-Reject message and reject the user's connection request.

If the user requires accounting, the RADIUS server will also include accounting information in the Access-Accept message. After the NAS receives this message, it will start billing.

Radius certification is widely used in many fields, including but not limited to:

1. Wireless network authentication: When a user connects to a wireless network, the RADIUS server can communicate with the user's device to verify their identity. Only after the verification process is completed, the user can successfully connect to the wireless network.
2. Dial-up authentication for remote access servers: Many organizations use RADIUS to provide authentication services for remote access to their servers. A RADIUS server can be configured to authenticate a user's username and password. If the authentication passes, the RADIUS server allows access to the server, otherwise access is denied.
3. Network management: The RADIUS protocol can also be used to control network management, such as controlling the possible access scope, restricting access to certain key network resources, etc. This is important to protect the security and confidentiality of your network.

As a Radius authentication server, Andang ASP identity authentication platform has the following more advantages:

1. Easy to integrate: Andang ASP identity authentication platform can communicate with various Radius clients and provide a unified authentication interface to facilitate integration with other systems.
2. Flexible authentication methods: Andang ASP supports multiple authentication methods, including username and password authentication, dynamic password authentication, fingerprint recognition, etc., which can be configured as needed.
3. Powerful permission management: Andang ASP adopts permission management based on the RBAC model, which can provide external permission verification interfaces to facilitate enterprises to conduct refined permission control.
4. Security audit function: Andang ASP provides a security audit function, which can record user behavior and system events, facilitate auditing and monitoring, and improve the security and stability of the system.
5. Good user experience: Andang ASP identity authentication platform provides a user self-service platform. Users can open accounts, set authentication methods and other operations through a few simple steps, providing a good user experience.
6. Centralized management: Andang ASP identity authentication platform can centrally manage the identity information and authentication methods of multiple users, making it convenient for enterprises to conduct unified management and maintenance.
7. High availability and scalability: Andang ASP identity authentication platform adopts a distributed architecture, which can support high-availability deployment of multiple authentication servers and can be expanded as needed to meet the growing needs of enterprises.
8. Powerful customization functions: Andang ASP identity authentication platform provides powerful customization functions, which can be customized and developed according to the special needs of enterprises to meet the personalized needs of enterprises.

In short, the Andang ASP identity authentication platform, as a Radius authentication server, has easy integration, flexible authentication methods, powerful rights management, security audit functions, good user experience, centralized management, high availability and scalability, and powerful automatic With advantages such as defined functions, it can provide enterprises with efficient, secure, and flexible identity, permission, and application management services.

The main difference between using the Andang ASP authentication platform as a Radius authentication server and building a free Radius authentication server yourself lies in the following aspects:

1. Cost investment: Building a free Radius authentication server yourself requires purchasing relevant servers and software, as well as configuration and debugging, which is relatively expensive. Using the Andang ASP authentication platform as the Radius authentication server only requires a certain service fee, and the cost is relatively low.
2. Technical threshold: Building a free Radius authentication server by yourself requires certain technical capabilities and experience, as well as knowledge of the Radius protocol, network security, etc. Using the Andang ASP authentication platform as the Radius authentication server does not require too many technical thresholds and can be used quickly.
3. Function and performance: Building your own free Radius authentication server can be customized and developed according to the actual needs of the enterprise, and has high flexibility and scalability. Using the Andang ASP authentication platform as the Radius authentication server has more functions and performance, such as supporting multiple authentication methods, high availability and scalability, security audit functions, etc.
4. Maintenance and management: Building a free Radius authentication server requires self-maintenance and management, including troubleshooting of server hardware and software, repair of security vulnerabilities, etc. Using the Andang ASP authentication platform as the Radius authentication server will provide professional maintenance and management services by the service provider, which can reduce the maintenance cost and technical burden of the enterprise.
