隨著工業(yè)化與信息化的融合推進(jìn)，以及以太網(wǎng)技術(shù)在工業(yè)控制系統(tǒng)中的大量應(yīng)用，病毒和木馬對SCADA系統(tǒng)的攻擊事件頻發(fā)，直接影響到公共基礎(chǔ)設(shè)施的安全，造成的損失不可估量。因此，目前國內(nèi)外生產(chǎn)企業(yè)都是否重視工業(yè)控制系統(tǒng)的安全防護(hù)建設(shè)。但由于工控網(wǎng)絡(luò)存在著特殊性，商用的信息安全技術(shù)無法完全適用，解決工業(yè)控制系統(tǒng)安全需要有針對性地實(shí)施特殊措施。?病毒泛濫也是總所周知的安全隱患。在全球范圍內(nèi)，每年都會發(fā)生數(shù)次大規(guī)模的病毒爆發(fā)，而全球現(xiàn)已發(fā)現(xiàn)數(shù)萬種病毒，每天還會新生數(shù)十余種。除了傳統(tǒng)意義上的具有自我復(fù)制能力、但必須寄生在其它實(shí)用程序中的病毒種類外，各種新型的惡意代碼更是層出不窮，如邏輯炸彈、特洛伊木馬、蠕蟲等，它們往往具有更強(qiáng)的傳播能力和破壞性。如蠕蟲病毒和傳統(tǒng)病毒相比，其最大的不同在于可以進(jìn)行自我復(fù)制，傳統(tǒng)病毒的復(fù)制過程需要依賴人工干預(yù)，而蠕蟲卻可以自己獨(dú)立完成，破壞性和生命力自然強(qiáng)大得多。隨著TCP/IP協(xié)議被控制網(wǎng)絡(luò)普遍采用，網(wǎng)絡(luò)通信協(xié)議漏洞問題變得越來越突出。TCP/IP協(xié)議簇最初設(shè)計的應(yīng)用環(huán)境是美國國防系統(tǒng)的內(nèi)部網(wǎng)絡(luò)，這一網(wǎng)絡(luò)是互相信任的，因此它原本只考慮互通互聯(lián)和資源共享的問題，并未考慮也無法兼容解決來自網(wǎng)絡(luò)中和網(wǎng)際間的大量安全問題。當(dāng)其推廣到社會的應(yīng)用環(huán)境后，安全問題就發(fā)生了。所以說，TCP/IP在先天上就存在著致命的設(shè)計性安全漏洞。工業(yè)控制系統(tǒng)的安全防護(hù)需要考慮每一個細(xì)節(jié)。從現(xiàn)場I/O設(shè)備、控制器，到操作站的計算機(jī)操作系統(tǒng)，工業(yè)控制網(wǎng)絡(luò)中同時存在保障工業(yè)系統(tǒng)的工業(yè)控制網(wǎng)絡(luò)和保障生產(chǎn)經(jīng)營的辦公網(wǎng)絡(luò)，考慮到不同業(yè)務(wù)終端的安全性與故障容忍程度的不同，防御策略和保障措施應(yīng)該按照等級進(jìn)行劃分，而實(shí)施分層次的縱深防御架構(gòu)需要分別采取不同的對應(yīng)手段，構(gòu)筑從整體到細(xì)節(jié)的立體防御體系。
