描述
國(guó)家信息安全漏洞共享平臺(tái)在2011年收錄了100多個(gè)對(duì)我國(guó)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(zhǎng)近10倍,這些漏洞涉及西門子等國(guó)內(nèi)外知名工業(yè)控制系統(tǒng)制造商的產(chǎn)品。
操作系統(tǒng)安全漏洞
PC與Windows的技術(shù)架構(gòu)現(xiàn)已成為控制系統(tǒng)上位機(jī)/操作站的主流,而在控制網(wǎng)絡(luò)中,操作站是實(shí)現(xiàn)與MES通信的主要網(wǎng)絡(luò)結(jié)點(diǎn),因此其操作系統(tǒng)的漏洞就成為了整個(gè)控制網(wǎng)絡(luò)信息安全中的一個(gè)短板。
網(wǎng)絡(luò)通信協(xié)議安全漏洞
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(jì)的應(yīng)用環(huán)境是美國(guó)國(guó)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(huì)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(jì)性安全漏洞。
