【導(dǎo)讀】絡(luò)安全的主要威脅因素,重點闡述了幾種常用的網(wǎng)絡(luò)信息安全技術(shù)。原先由單機安全事故引。安全機制的缺乏和防護意識不強,網(wǎng)絡(luò)風(fēng)險日益加重。一個操作系統(tǒng)或網(wǎng)絡(luò)軟件的出現(xiàn)都不可能是無缺陷和漏洞的。我們的計算機處于危險的境地,一旦連接入網(wǎng),將成為眾矢之的。除非用戶禁止該程序或?qū)ζ溥M行正確配置,否則,安全隱患始終存。計算機病毒具有傳染性、寄生性、隱。因此,提高對病毒的防范刻不容緩。其危害性非常大。的電腦病毒更為嚴重。網(wǎng)通信強制實施訪問控制的安全應(yīng)用措施。信是否被允許,并監(jiān)視網(wǎng)絡(luò)運行狀態(tài)。中,即在其硬件產(chǎn)品中采取功能更加先進的安全防范機制。數(shù)據(jù)加密技術(shù)是為提高信息系統(tǒng)及數(shù)據(jù)的。更換與銷毀等各環(huán)節(jié)上的保密措施。此外,天災(zāi)人禍、不可抗力等所導(dǎo)致的事故也會對信息系統(tǒng)造成毀。數(shù)據(jù)容災(zāi)使用兩個存儲器,在兩者之間建立復(fù)制關(guān)。IP相連,構(gòu)成完整的數(shù)據(jù)容災(zāi)系統(tǒng),也能提供數(shù)據(jù)庫容災(zāi)功能。
