Basic router knowledge

Understanding basic router knowledge is also very helpful for Routers. Next we will explain some basic router knowledge. Reliability requirements are proposed for fault recovery and load capabilities. For routers, reliability is mainly reflected in interface faults and increased network traffic. Therefore, backup is an indispensable means of routers. When the primary interface fails, the backup interface is automatically put into operation to ensure the normal operation of the network. When the network traffic increases, the backup interface can undertake Load Balancing tasks.

Router basic knowledge-Identity Authentication

Identity Authentication in Routers mainly includes identity authentication when accessing the vro; Identity Authentication for the peer vro and identity authentication for route information.

Access Control Based on vro basic knowledge

A. Hierarchical password protection is required for vro access control;
B. IP address-based access control;
C. User-based access control.

Basic router knowledge hiding

When communicating with the peer end, it is not necessary to communicate with the real identity. Through address translation, you can hide the Intranet address and only access the external network as a public address. Except for the first connection initiated by the internal network, users cannot directly access the resources in the network through address translation.

Basic knowledge about vro Data Encryption

In order to avoid information leakage caused by data eavesdropping, it is necessary to encrypt the transmitted information. Only the peer that communicates with it can decrypt the ciphertext. By encrypting the packets sent by the vro, even if the packets are transmitted over the Internet, the private, integrity, and authenticity of the data are ensured.

Router basic knowledge-Attack Detection and Prevention

As an external interface device of an internal network, a vro is the first target for attackers to access the internal network. If the router does not provide attack detection and prevention, it is also a bridge for attackers to enter the internal network. Provides attack detection on the vro to prevent some attacks.

Vro basic knowledge-Security Management

Each datagram between an internal network and an external network is transmitted through a vro. Audit of packets on a vro provides necessary information for network operation and helps you analyze the running status of the network. Vendors provide different solutions. For example, Huawei Quidway series routers provide a comprehensive network security solution, including user verification, authorization, and data protection. The security technologies used include: callBack technology, backup center, AAA, CA technology, packet filtering technology, address translation, VPN technology, encryption and key exchange technology, smart firewall and security management.
