【摘要】：随着计算机网络和互联网的快速发展,基于计算机网络的企业应用程序也在迅速增加,同时网络信息系统也为企业带来了巨大的便利和经济效益。企业网络办公系统将成为企业日益重要的资源和平台,但紧随其后的网络安全问题也在开始困扰着用户,这就对企业网络信息安全提出了更高的要求。但是计算机网络系统在给用户带来便捷信息访问和巨大的资源访问的同时,也蕴含着许多危险。经过统计,企业网络系统的威胁主要来自以下几个方面而来:1.网络病毒的入侵:自从计算机病毒出现之后,其增长速度非常迅速,对计算机用户造成的损失也是不可估量的,计算机网络一旦感染病毒,轻者计算机系统运行速度降低,重者还有可能导致用户重要资料泄露,甚至是计算机硬件损坏。2.网络黑客的攻击:在网络上,黑客们运用各种工具入侵他人计算机系统,窃取他人重要信息或破坏他人网络的正常使用。更加严重的情况则可能会导致计算机系统的崩溃和网络系统的瘫痪。3.信息传输过程中的隐患:在传输过程中,源端与目的端进行数据交换不可避免地会有一定数量的数据丢失或者被他人盗取,亦或者被他人修改,这将会对数据的完整性造成破坏。4.企业对于计算机网络安全的防范不足:由于网络系统涉及企业日常运行许多环节,整个网络要同时执行很多操作,因此不可避免地会有来自各个方面的攻击。5.计算机网络系统自身的缺陷:有部分企业信息系统使用的平台存在一定的安全漏洞,这样就导致非法用户可以未经授权获得部分访问权限或提高其访问权限。6.内部攻击:由于企业内部的防范工作出现漏洞,内部的员工可能会进行一些有意或无意的误操作,这样也是企业网络安全的问题隐患之一。通过对以上几个方面的问题分析,企业信息系统的建设需要一整套完整的解决方案,这个方案对现代企业的规模发展有着极其重要的意义。这个解决方案需要涵盖网络系统各个方面,从整个网络系统的安全管理到单机系统的安全加固,从规章制度的完善到技术手段的改进。从业务和技术方面都需要一个易于实施、部署、建立的相对完整的系统,为企业信息安全、信息系统有效地防止来自各个方面攻击和威胁,以尽量减少风险水平。
[Abstract]:With the rapid development of computer network and Internet, the enterprise application program based on computer network is also increasing rapidly. At the same time, network information system has brought great convenience and economic benefit to enterprises. The enterprise network office system will become an increasingly important resource and platform for enterprises, but the following network security problems are beginning to haunt users, which puts forward higher requirements for enterprise network information security. But computer network system not only brings convenient information access and huge resource access to users, but also contains many dangers. According to statistics, the threat of enterprise network system mainly comes from the following aspects: 1. 1. The invasion of network virus: since the emergence of computer virus, its growth rate is very fast, and the loss to computer users is incalculable. Once computer network is infected with virus, the running speed of light computer system is reduced. What's more, it can lead to the disclosure of important user information, even computer hardware damage. 2. 2. Network hackers attack: on the network, hackers use various tools to break into other people's computer systems, steal important information of others or destroy the normal use of other people's networks. A more serious scenario could lead to a crash in computer systems and paralysis in network systems. Hidden trouble in the process of information transmission: in the process of transmission, there will inevitably be a certain amount of data lost or stolen or modified by others during the data exchange between the source and the destination. This will damage the integrity of the data. Because the network system involves many links of the enterprise's daily operation, the whole network must carry out a lot of operations at the same time, so it is inevitable that there will be attacks from various aspects. The defect of the computer network system itself: there are some security vulnerabilities in the platforms used by some enterprise information systems, which leads to illegal users can obtain partial access rights without authorization or increase their access rights .6. Internal attack: because of the loopholes in the prevention work inside the enterprise, the internal staff may carry out some intentional or unintentional misoperation, which is also one of the hidden dangers of the enterprise network security. Through the analysis of the above problems, the construction of enterprise information system needs a complete set of solutions, which is of great significance to the scale development of modern enterprises. This solution needs to cover all aspects of the network system, from the security management of the entire network system to the security reinforcement of the stand-alone system, from the improvement of the rules and regulations to the improvement of the technical means. From the aspect of business and technology, we need a relatively complete system that is easy to implement, deploy, and build. For enterprise information security, information system can effectively prevent all kinds of attacks and threats, in order to minimize the level of risk.
