21世纪的我们,从过去统一的中山装到现在五颜六色的服装;从过去一个村里只有一个雪花电视到现在每家每户的电视、电脑等各种电器;从过去的占地170平方米,重达30吨,耗电功率约150千瓦,每秒钟可进行5000次运算的一个庞然大物的世界上的第一台计算机到现在简单、轻巧、便捷的计算机。这些变化凸现出时代在发展,科学技术在发展,我们的计算机网络技术水平也得到了巨大的进步。而且近年来,计算机网络技术飞速发展,在我们的生产和我们的生活中发挥着一定的重要作用。尽管如此,每一件事物有利必然也有弊。计算机网络技术确确实实是给我们带来了极大的便利,但计算机网络安全问题也存在很多不利的因素。例如,计算机网络会使我们的信息泄露,计算机网络犯罪层出不穷,计算机网络会对我们产生一定的经济损失问题也在日益上升。因此,本文对在计算机网络中存在的相关问题进行分析与探讨,并且提出有效的针对计算机网络安全问题的具体防范措施。
In the 21st century, we, from the uniforms of Zhongshan, now wears colorful clothes. From the past, there was only one snowflake TV in every village to every kind of household TV, computer and so on. From the past 170 square meters, 30 tons, power consumption of about 150 kilowatts, 5000 operations per second for a monster in the world’s first computer to the present simple, lightweight and convenient computer. These changes highlight the development of the times, the development of science and technology, and the great progress of our computer network technology. And in recent years, the rapid development of computer network technology plays an important role in our production and our life. In spite of this, everything has its own advantages and disadvantages. Computer network technology really gives us great convenience, but there are many disadvantages of computer network security issues. For example, the computer network will make our information leaked, cyber criminality will emerge in an endless stream, and the computer network will cause some economic loss to us. Therefore, this paper analyzes and discusses the related problems existing in the computer network, and puts forward the specific countermeasures for the computer network security problem effectively.
