Analysis of Computer Network Security Problems and Countermeasures

Current Status of Computer Network Security 
In fact, there are various factors that have varying degrees of influence on the computer network, 
including not only the computer network itself, but also issues with the computer loopholes. 
Besides, they are also related to the network users to certain degree. On the specific situation of 
computer network security, existing problems to the network security are mainly in the following 
aspects: 
Poor Safety Supervision. In addition to enhancing the security of computer network, there 
should also be a powerful supervision system. As is known to all, good supervision can eliminate 
many hidden dangers and lift network security. At present, there is still a large gap in the security 
supervision of computer network and there is no scientific and effective regulatory evaluation 
mechanism, which brings risks to the safe operation of computer network. 
Problems with the Network. Most of the current computer network systems have loopholes, 
and network hackers take advantage of network loopholes to attack the computer system wantonly 
so as to achieve remote operation, posing threats to computer network personnel. The main reasons 
for the above problems are: 
(1) Extensibility and stability are limited. In the early stage of the design of the network 
system, due to the lack of comprehensive consideration, resulting in the computer system in the 
normative and rationality of the existence of different loopholes in the operation of the network 
system had a direct impact; 
(2) Vulnerability in network file server. File server is the computer network hub, the 
operation of this server on the computer network operation has a greater impact. From a practical 
point of view, many designers in the design process without the need for network applications to 
fully consider the lead to unreasonable and imperfect existence, the impact of computer network 
security; 
(3)Vulnerability in the use of the network system. In the provision of switches and firewalls 
and other equipment, the corresponding lack of standard specifications, for the corresponding level 
of security and data needs to deploy the network, and then the computer network fast and safe to 
balance, thus we should have a deep reflection on this.
