摘 要
文中就信息網(wǎng)絡(luò)安全內(nèi)涵發(fā)生的根本變化，闡述我國(guó)發(fā)展民族信息安全體系的重要性及建立有中國(guó)特色的網(wǎng)絡(luò)安全體系的必要性。論述了網(wǎng)絡(luò)防火墻安全技術(shù)的分類及其主要技術(shù)特征。文中論述了防火墻部署原則，并從防火墻部署的位置詳細(xì)闡述了防火墻的選擇標(biāo)準(zhǔn)。并就信息交換加密技術(shù)的分類及RSA算法作以分析，針對(duì)PKI技術(shù)這一信息安全核心技術(shù)，論述了其安全體系的構(gòu)成。略談了人類從過(guò)去的時(shí)代到現(xiàn)在網(wǎng)絡(luò)如此發(fā)達(dá)的時(shí)代，網(wǎng)絡(luò)時(shí)代發(fā)展的一些特點(diǎn)，技術(shù)，信息網(wǎng)絡(luò)時(shí)代，信息成為重要的經(jīng)濟(jì)資源。這即是所謂的知識(shí)經(jīng)濟(jì)："盡管所有經(jīng)濟(jì)制度都是建立在知識(shí)基礎(chǔ)之上，但以往未被計(jì)入成本，只有信息化時(shí)代，這種資源才成為主要資源。它可以共享，可以倍增；可以無(wú)限制的創(chuàng)造。知識(shí)取代資本：人力資本比貨幣資本更重要"，到并從簡(jiǎn)單到難度較大的方的一些技術(shù)來(lái)向大家闡述網(wǎng)絡(luò)一些簡(jiǎn)單的技術(shù)，然后到一些難度較大的技術(shù)。從網(wǎng)絡(luò)的幾大特點(diǎn)，信息安全是國(guó)家發(fā)展所面臨的一個(gè)重要問(wèn)題，防火墻，防火墻的選擇，等等來(lái)談一下網(wǎng)絡(luò)技術(shù)。

Abstract
In the article the radical change which occurs on the information network security connotation, elaborated our country develops the nationality information security system importance and the establishment has the Chinese characteristic the network security system necessity. Elaborated the network firewall security technology classification and its the main technical characteristic. In the article elaborated the firewall deployment principle, and the position which deployed from the firewall in detail elaborated the firewall choice standard. And does on the exchange of information encryption technology classification and the RSA algorithm by analyzes, in view of the PKI technology this information security core technology, elaborated its security system constitution. Discussed slightly the humanity from the past time to the present network so developed time, network time development some characteristics, the technology, the information network time, the information becomes the important economical resources. This is the so-called knowledge economy: "although all economic system all is the establishment above the knowledge foundation, but formerly has not been included the cost, only then the becoming an information based society time, this kind of resources only then become the main resources. It may share, may multiply; May the unlimited creation. Knowledge substitution capital: The human capital money capital is more important than ", to and from as simply comes as difficulty big side some technologies to everybody elaboration network some simple technologies, then to some difficulty big technologies. From network several major characteristics, the information security is an important question which the national development faces, the firewall, the firewall choice, and so on discusses the network technology.
