计算机数据入侵检测技术是一种在计算机使用过程中,对违反数据库安全指标或遭到的非法攻击进行检测与识别的技术。主要通过采集、分析网络运行环境以及计算机系统中的检测数据,识别可疑事件与非法攻击,并采取相应防御技术自动抵御攻击行为,降低计算机数据库的损失。当前,计算机数据库入侵检测技术还存在着检测正确率低、漏报与误报率高以及防御功能较差等问题,因此,深入研究计算机数据库入侵检测技术,优化并完善入侵检测技术,对于保障计算机数据库的安全性具有积极的现实意义。
Computer data intrusion detection technology is a computer in the process of using, in violation of database security indicators or illegal attacks were detected and identified technology. Mainly through the acquisition, analysis of network operating environment and computer system testing data to identify suspicious events and illegal attacks, and take appropriate defense technology to automatically resist attacks, reducing the loss of computer database. At present, computer database intrusion detection technology has the problems of low detection accuracy, omission and false positive rate, and poor defense function. Therefore, in-depth study of computer database intrusion detection technology, optimization and improvement of intrusion detection technology, to protect the computer Database security has a positive and practical significance.
