计算机网络系统是企业信息化系统正常运行的的支撑,一旦网络系统出现故障,就会影响到整个企业的生产和经营。所以,计算机系统是否安全可靠,对企业的经营和发展起着重要作用。然而,由于网络系统的开放性、信息资源的共享性、通信信道的公用性、连接形式的多样性等,使得网络存在很多严重的脆弱点,再加上计算机病毒在不断的产生和传播,计算机网络也不断地遭受黑客的袭击,甚至造成网络系统的瘫痪,这给许多企业造成了巨大的经济损失,甚至危害到国家和人们的安全。因此针对来自不同方面的安全威胁,我们必须清醒地认识这些安全威胁,并需要采取有效的而又有针对性的安全对策,使计算机网络更好地为企业服务。
Computer network system is the normal operation of enterprise information system support, once the network system failure, it will affect the entire enterprise production and management. Therefore, whether the computer system is safe and reliable plays an important role in the operation and development of enterprises. However, due to the openness of the network system, the sharing of information resources, the commonality of communication channels and the diversity of connection forms, there are many serious vulnerabilities in the network. Coupled with the continual generation and spread of computer viruses, computers The network has been continuously attacked by hackers and even caused the network system to be paralyzed. This has caused huge economic losses to many enterprises and even endangered the security of the country and people. Therefore, in order to address security threats from different aspects, we must clearly understand these security threats and need to take effective and targeted security measures to make the computer network better serve the enterprise.
