Upgrade the immune route to create a virus-free internet cafe (1)

If the Internet is disconnected, the Internet is disconnected, and the network is stuck, you may be afraid of these problems in Internet cafe operations. Recently, such problems have become more and more.

Vro changed, ARP bound, and PC antivirus... Faults still occur frequently, and Internet cafe staff are almost lost. What is the reason for this annoying problem?

Tracing, virus attacks are the culprit! In addition, apart from various factors such as unstable lines, Internet attacks, and man-made damages, the main cause of the failure of Internet cafes is the internal network virus! According to Xin Xiang's tracing and Analysis of router user problems, more than 10 types of network viruses are currently prevalent in Internet cafes, and they are becoming increasingly popular. These viruses include ARP spoofing, SYN Flooding Attacks, IP Address Spoofing, specific port attacks, UDP Flooding attacks, and IP fragmentation. In addition, various attacks form a combination mode. This virus cannot be killed locally because it is not on a PC hard disk, but on a network server, such as private game servers, FTP servers, peer-to-peer P2P servers, and some web pages. Once Internet users access these Internet addresses, the virus will quietly intrude into the local PC and attack in the internal network, making it difficult to prevent attacks.

Is there a way to solve this problem? Of course. Xin Xiang put forward several measures to help users solve these problems, which is remarkable in practice. These measures can be called the conventional measures to prevent Internet cafes from viruses. At the same time, Xin Xiang also invented the "immune network" technology, as a more effective fundamental means of virus prevention, is providing Internet cafe users suffering from viruses. "Upgrading the immune network and creating a virus-free internet cafe" is an important means and slogan for us to continue to fight against Internet cafe viruses and attacks.

Next, let's talk about some common measures Xin Xiang suggested for their users to solve the internet cafe virus problem:

1. Four conventional means-policy and control

1. ARP binding

ARP spoofing is a relatively early virus pattern and is now subject to two-way binding. As Xin Xiang routing has the ARP innate immune function, you can perform one-way binding on the PC end. For some Internet ARP users, especially those with shared bandwidth, Xinxiang routing is also immune and can be used. Although users are familiar with the principles and harms of ARP spoofing, the virus has not died. Therefore, we strongly recommend that users bind ARP packets as necessary.

2. Take traffic restriction measures

Most viruses attack flood packets to consume resources of the entire system, especially routers. Therefore, traffic restrictions on each PC can play a role in anti-virus. The traffic limit can be two methods at the same time, one is the number of sessions, and the other is the bandwidth limit.

The SESSION limit is to control the number of sessions that a single PC sets up for Internet access requests. It is generally set to-according to the actual environment. The bandwidth limit is the control of the total amount of data initiated on the PC. Xin Xiang's bandwidth management mode in the route can provide intelligent and elastic bandwidth management, effectively limiting the amount of data of virus attacks.

3. Enable the routing Firewall

A stable vro requires a complete firewall and provides more reliable firewall functions for the Intranet. Xin Xiang has designed many protection rules to control known viruses. Xin Xiang told users not to worry that the firewall will greatly reduce the forwarding efficiency as they usually think. Xin Xiang's route design is optimized in terms of stability and high speed, which can ensure the best of both worlds.
