Main factors affecting network security

Source: Shangpin China | Type: website encyclopedia | Time: June 20, 2014
As the network becomes more and more official and commercial, network security has become an important concern. There are many factors that affect network security. Some factors may be cured by reason (such as being loyal to others), or they may be biased (such as where the message was sent, ironic); It may be man-made or non-human; It may also be the illegal use of network system resources by foreign attacks. To sum up, in addition to the threats to the network from the environment and disasters due to agriculture, such as floods, fires, land, and the radiation of Diansheng Network design The security of the system mainly comes from the following aspects.

 
network security

1、 Human factors

In the question of network security, human factors are very important. Most network security incidents are caused by human factors. They are not only dangerous, but also difficult to prevent. Human demands can be divided into intentional and unintentional situations. The more it refers to the man-made vicious attacks on the network and the implementation of disciplinary, illegal and obedient activities. No anger refers to the operation loss caused by network managers and successful users due to their work. Although it is not the main reason, it will also cause adverse consequences to the network system. For example, the security breach caused by the photographer's improper allocation of information, the user's failure to recognize the security information and the improper password selection, and the security gap in the software developed by programmers.

2、 Network communication protocol has inherent security vulnerabilities
 
Because TCP/IP protocol is specially designed for the interconnection of monthly networks in a trusted environment, the overall concept and design of security have been created since the beginning. The Internet is an open and free network. While it increases the flexibility of network information services, it also opens the door for attacks and people to win. As a result, there are many safe sleep. Not only has the border crossing disease accelerated the speed of passing on the Internet and expanded the circle of spreading models, but also various analytical attacks against network protocols and applications are emerging in endlessly.
   
3、 Computer hardware system failure
 
Any computer system has security problems. It can be said that absolutely secure computer systems do not exist at all. Obviously, the network composed of any computer system cannot be called absolutely safe. For any computer system, as long as you use squid, there are more or less security problems, but the degree is different. For network interconnection equipment, such as router, it undertakes public data exchange and forwarding tasks on the Internet. Its functions are powerful and complex. It is impossible to constitutionally exempt Tangrun due to the current technology.
 
4、 . Congenital defects of operating system
 
The operation is not uniform, and there are all kinds of soups. For example, you can create and liven processes remotely. The security authentication function provided by Ju is limited; The password free population provided for system opening. As a matter of fact, the shortcomings of the operating system can be overcome through the continuous upgrade of the version. Our constant increase of intestinal function will also bring about a break.
   
5、 Defects and loopholes in network database and application software
 
The great security problem of network database and application software comes from software design and software engineering. However, these small islands and defects are the preferred targets for hackers to attack. Many system human handsome events are mostly caused by the database or application software that has security updates and incomplete security measures. In addition, some software backdoors are designed by software designers and programmers for their own reasons. Generally, they are unknown to outsiders. However, once the backdoors are opened, The consequences will be unimaginable.
