Intrusion detection system collects the information from the main part of computer network system , then monitors and controls the computer and network traffic for intrusive and suspicious activities . they detect the intrusion not only from the extranet hacker , but also from the intranet users 入侵检测( intrusiondetection )就是对计算机网络和计算机系统的关键结点的信息进行收集分析,然后对计算机和网络资源上的恶意使用行为进行识别和响应,检测其中是否有违反安全策略的事件发生或攻击迹象,并通知系统安全管理员。
If a person ' s nervous system has the problem , may imagine in the information transmission can have the problem , can neglect the reflection which foreign stimulates , even is the information receiving system has the disorder ; same if in enterprise information construction process if does not have ( enterprise information construction infrastructure which the corresponding computer network system will build also will be we usually said ) , then the information transmission definitely can have the problem , enterprise ' s information construction also becomes a paper empty talk , even can have " ten thousand ten feet tall buildings sand beaches to get up , a night caves in the regret not already " feeling 如果一个人的神经系统出现问题,可以想象在信息的传达上就会出现问题,就会忽视对外界刺激的反映,甚至是信息接收系统发生紊乱;同样的如果企业信息化建设过程中如果没有将相应的计算机网络系统搭建好(也即是我们通常所说的企业信息化建设的基础设施) ,那么信息的传输肯定会出现问题,企业的信息化建设也就成为一纸空谈,甚至就会有“万丈高楼沙滩起,一夜坍塌悔不已”的感觉。
The yellow river water environment information management system is a computer network system covering the whole basin , the construction of which includes a computer network construction and software development . the software involves database , gis , and man - machine interface . the investment in the system is huge and the period of construction is long , thus , a good design is very important . the design schemes are summarized in this paper . according to the present computer technology , some new methods used in network design and software development are introduced , and it is suggested that expandability and opening of the system should be considered in system construction 黄石?水电站输水渠道地处地质结构比较复杂的地方,由于渠道建成投运的时间较早,且原设计的标准较低,糙率较大.在电站机组已更新改造的情况下,若不进行输水渠道挖潜改造,已难于满足电站机组的设计流量要求.经反复比较,决定采取减小渠道糙率的方案,对输水渠道进行三面光护面加固防渗,增加过流,效果很好
To build a rain water conditions for the protection of information collection - based communications , computer network system to rely on , water application systems at the core information services system project . . the entire system is the starting point of building high - technology advanced , reached advanced international level . the first project implemented as domestic water monitoring system project management 从大伙房水库流域水文自动测报系统项目管理模型的建立和应用,可以看出企业及项目管理者和项目参与者只有真正掌握项目管理的精髓,才能提升项目管理的水平和能力,才能保证项目的成功,完成组织所赋予项目的特定目的。
The essay mainly researches on the technologies that composed of computer networking systems based on the stratus technology thery ; it detailedly introduces the stratus technology , the components of computer network system and fulfillment technologies for the key devices , redundancy designs , twin online backups and cluster technologies ; also particularly , it presents the building models and building processes for the computer networking system on both hardware and software hands ; it describes the designing and building procedures of its local area network by showing us the real situation of harbin red - cross blood bank 文中详细介绍了容错技术的内容、计算机网络系统的组成部分和关键设备、冗余设计、双机热备和集群技术等实现技术。重点从软件和硬件两方面阐述了计算机网络系统的构建模型和构建过程。描述了结合哈尔滨红十字中心血站的实际情况,完成了其计算机局域网络的设计和实现的过程。
