近年来,计算机的网络安全技术得到了迅速发展,为了能够为自动化技术的功能发挥创造一个秩序化以及非常可靠的操作氛围,计算机网络安全技术的发展一定要与信息化计算机技术的发展步伐相一致。本文主要是以网络安全入侵检测为研究对象,之后通过异常性的检测技术、误用性的检测技术以及完整性的检测技术三大方面对研究对象进行进一步的探讨和分析。 In recent years, computer network security technology has been rapid development, in order to be able to function for automation technology to create a orderly and very reliable operating atmosphere, the development of computer network security technology must be consistent with the pace of development of computer information technology . In this paper, we mainly take network security intrusion detection as the research object, and then through the abnormal detection technology, misuse detection technology and the integrity of the detection technology three major aspects of the study to further explore and analyze.
