. Currently, RADIUS supports the following authentication methods: ① user name and password authentication; ② PAP authentication; ③ CHAP authentication. RADIUS is composed of two parts: the client and the server. The client sends authentication and billing requests to the server. The server sends back and receives or denies messages to the client. Communication between the client and the server is used to share key encryption.The yanyang Security VPN

The Enable nat-traversal is used to configure NAT traversing, which is not optional for both sides of the public address. Peer Status detection is used to detect

Install Strongswan: an IPsec-based VPN tool on Linux IPsec is a standard that provides network layer security. It contains Authentication Header (AH) and security load encapsulation (ESP) components. AH provides the integrity of the package, and the ESP component provides the confidentiality of the package. IPsec ensures security at the network layer.

Http://91mail.51.net supply Currently, companies with relatively large scales all have their own subsidiaries. How to keep the branches safe, efficient, low-cost, and multi-purpose connections with the company's headquarters at any time is a challenge facing every enterprise. Traditional methods include leased line connection, dial-up connection, and direct access to IP addresses. However, they are either expensive or have a single function, which may pose security risks. Using a

With the development of network communication technology and the emergence of network applications, more and more user data and enterprise information are transmitted over the Internet. As a result, more and more hackers and cyber threats are emerging. they steal, tamper with, and destroy confidential and sensitive data to achieve their ulterior motives. Therefore, with the development of network communication technology and the emergence of network applications, more and more user data and ente

In fact, the VPN settings of the D-link router are very similar to those of other route VPN settings. Next we will explain the configuration steps of using the DLINK router to establish a point-to-point VPN, in the following article, we will take the most common method of static IP addresses at both ends as an example to describe the Setting Process of 804HV.

You need to install a certificate Server in the VPN server intranet, and then have the VPN server trust the certification authority, and then publish the Certificate Server and download the certificate. VPN clients need access need to download the installation certificate before they can c

IPSec as a protocol family (that is, a series of interrelated protocols) consists of the following parts: (1) Protection of packet flow protocols; (2) key exchange protocols used to establish these secure packet flows. The former is divided into two parts: Encrypted packet flow Encapsulating Security Payload (ESP) and less-used authentication headers (AH), the authentication header provides authentication to the packet stream and guara
