描述
?隨著工業(yè)化與信息化的融合推進，以及以太網(wǎng)技術在工業(yè)控制系統(tǒng)中的大量應用，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設施的安全，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)的安全防護建設。但由于工控網(wǎng)絡存在著特殊性，商用的信息安全技術無法完全適用，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制能力、但必須寄生在其它實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行自我復制，傳統(tǒng)病毒的復制過程需要依賴人工干預，而蠕蟲卻可以自己獨立完成，破壞性和生命力自然強大得多。國家信息安全漏洞共享平臺在2011年收錄了100多個對我國影響廣泛的工業(yè)控制系統(tǒng)軟件安全漏洞，較2010年大幅增長近10倍，這些漏洞涉及西門子等國內(nèi)外知名工業(yè)控制系統(tǒng)制造商的產(chǎn)品。? PC與Windows的技術架構(gòu)現(xiàn)已成為控制系統(tǒng)上位機/操作站的主流，而在控制網(wǎng)絡中，操作站是實現(xiàn)與MES通信的主要網(wǎng)絡結(jié)點，因此其操作系統(tǒng)的漏洞就成為了整個控制網(wǎng)絡信息安全中的一個短板。?隨著TCP/IP協(xié)議被控制網(wǎng)絡普遍采用，網(wǎng)絡通信協(xié)議漏洞問題變得越來越突出。TCP/IP協(xié)議簇最初設計的應用環(huán)境是美國國防系統(tǒng)的內(nèi)部網(wǎng)絡，這一網(wǎng)絡是互相信任的，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)絡中和網(wǎng)際間的大量安全問題。當其推廣到社會的應用環(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計性安全漏洞。
