Brief analysis network security technology
In the past two centuries, industrial technology represents a country's military and economic strength. Today, the rapid development of information technology in the twenty-first century have enhanced overall national strength of the key.
With the development of computer technology in the computer business has been based on a single mathematical computing, document processing, based on a simple link to the internal network of internal business processes, such as office automation to the development of enterprises based on the complexity of the intranet, extranet, The global Internet enterprise-class computer systems and dealing with the world of business and information-sharing deal. In the information processing capacity, the ability to link the system has been improved. But the link in the information capacity, the ability to improve circulation at the same time, Web-based connections are also becoming more prominent security issues. This article from the following areas to explore:
First, in an open network at the same time there are security issues .
Internet's openness as well as other factors led to the network environment, the computer system is riddled with security problems. In order to address these security issues, a variety of safety mechanisms, strategies and tools for research and application have been. However, even in the use of existing tools and mechanisms for security, network security is still a great danger that these potential safety problems can be attributed mainly to the following:


過去兩個(gè)世紀(jì)中，工業(yè)技術(shù)代表了一個(gè)國家的軍事實(shí)力和經(jīng)濟(jì)實(shí)力。飛速發(fā)展的今天，對信息技術(shù)的掌握是在二十一世紀(jì)增強(qiáng)綜合國力的關(guān)鍵。
隨著計(jì)算機(jī)技術(shù)的發(fā)展，在計(jì)算機(jī)上處理業(yè)務(wù)已由基于單機(jī)的數(shù)學(xué)運(yùn)算、文件處理，基于簡單連結(jié)的內(nèi)部網(wǎng)絡(luò)的內(nèi)部業(yè)務(wù)處理、辦公自動(dòng)化等發(fā)展到基于企業(yè)復(fù)雜的內(nèi)部網(wǎng)、企業(yè)外部網(wǎng)?、全球互聯(lián)網(wǎng)的企業(yè)級計(jì)算機(jī)處理系統(tǒng)和世界范圍內(nèi)的信息共享和業(yè)務(wù)處理。在信息處理能力提高的同時(shí)，系統(tǒng)的連結(jié)能力也在不斷的提高。但在連結(jié)信息能力、流通能力提高的同時(shí)，基于網(wǎng)絡(luò)連接的安全問題也日益突出。本文主要從以下幾個(gè)方面進(jìn)行探討：
一、 網(wǎng)絡(luò)在開放的同時(shí)存在的安全問題
