Computer network in the process of people's use, carrying a variety of data transmission, information communication tasks, all the time running, can be considered an active organism. As the name implies, the immune network is like the human body with "defense, stability, monitoring" function. Therefore, the role of the immune network is to make the network through the installation of the immune wall to achieve the effect of stability and robustness.
Specifically, the immune wall is mainly to solve the system security of the intranet and Internet behavior management. Customarily, the Internet is the extranet, and the local area network of the enterprise is connected to the extranet through broadband, which corresponds to become the intranet. As a result, the intranet constitutes an independent system similar to the human body. An immune wall plays a role in this independent intranet system.
At present, the problem of intranet mainly occurs in two aspects, one is the proliferation of network viruses, which can uncontrollably invade into the intranet to attack and deceive, and cannot be prevented; the other is the network end-user uncontrolled download, resulting in bandwidth abuse, affecting the smooth operation of the entire network. As a result, nowadays, the enterprise network commonly occurs drop, lag, stolen, difficult to manage, inefficient failure. This unstable and insecure network state is just like the human body, which is sick and immune. So, how does the immune wall enable the network to have an immune function, so as to achieve the purpose of stability and robustness?
First, it is a defense against network viruses. Only by effectively preventing the onset of viruses can we keep the network in a healthy state and ensure that the network is safe and stable.
For the biggest factor affecting the network, network protocol-based viruses through the usual Internet operations to Trojan horses, hacking, etc., very stealthy and quickly launched an attack on the network. The usual traditional means of virus checking and filtering have been powerless against them. Waiting for the virus to enter and attack, and then looking for the appropriate means to check and kill, has been completely lagging behind the disaster. At the same time, many times the virus does not reside in the intranet system, after the attack is likely to be no trace. In addition, hacker attacks are not carried out in the form of viruses, anti-virus is even more impossible to talk about. Therefore, the most important thing to cope with network disasters is not to check and kill after the fact, but to strengthen the immunity and active defense. In other words, even if the system is infected with a virus, the immune wall should be able to ensure that the virus and attacks can not attack. Just like the human body, exposure to hepatitis, intestinal, respiratory and other viruses, due to the role of autoimmunity, does not necessarily get sick. Therefore, the immune wall is different from antivirus software, anti-virus wall, its role is to improve network immunity, in contact with viruses and attacks, to stop their attacks.
The second is the management of Internet behavior. Security and management are inseparable, disorderly Internet behavior can not guarantee the stability of the network, high-speed, smooth. The harm to the network is also very serious, no less than the destructive effect of the virus attack.
The intranet is a *** enjoyment of Internet access, access bandwidth and network traffic have certain restrictions. If a terminal with a large amount of data transmission will cause the abuse of bandwidth, affecting the network of other terminals within the Internet operation, the seriousness of the entire network is completely trapped in a stagnant paralyzed state. Common BT, Thunderbolt downloads, pplive live streaming and other popular online means, it is very easy to play a bad role. In addition, unhealthy access will also be infected with network viruses, such as involving QQ promiscuity, illegal websites, pornographic information, etc., the chances of infection will be greatly increased. The role of the immune wall is to provide network administrators with an effective means of regular and selective control of these Internet behaviors, to ensure that the network is always in a controlled security state, the stability of the intranet will be guaranteed. Image to understand, do not smoke, do not drink, often eat vegetables and fruits, is to improve human immunity, to maintain health means. And the immune wall through the management of online behavior, to strengthen the network system robustness, to prevent beforehand, play the same role.
Immunity Wall fills the gap in the field of enterprise intranet security and management, is a new technology in the network era. 2007, Beijing Xinquanxiang company through years of research and development, and finally realized this revolutionary scientific and technological breakthroughs. In the process of Chinese enterprises to comprehensively promote information modernization, Xinxin to the immune wall technology will undoubtedly play an effective role in helping. Immunity wall is a perfect set of technical ideas, you can let the software installed and run independently, can also be mounted on the existing system to achieve.
