描述
SCADA和工業(yè)協(xié)議。MODBUS/TCP、EtherNet/IP和DNP3等在工業(yè)控制系統(tǒng)中被大量使用，但是這些協(xié)議在設計時沒有安全加密機制，通常也不會要求任何認證便可以在遠程對一個控制裝置執(zhí)行命令。這些協(xié)議應該只被允許在控制網(wǎng)絡單向傳輸，不準許在辦公網(wǎng)絡穿透到控制網(wǎng)絡。能夠完成這一功能的工業(yè)防火墻或者安全路由器，通常被部署在具有以太網(wǎng)接口的I/O設備和控制器上，從而避免因設備聯(lián)網(wǎng)而造成的病毒攻擊或廣播風暴，還可以避免各子系統(tǒng)間的病毒攻擊和干擾。
分布式組件對象模型(DCOM)。在過程控制中，OLE和ProfiNet(OPC)是使用DCOM的，它運用了微軟的遠程過程調(diào)用服務。該服務有很多的漏洞，很多病毒都會利用這個弱點獲取系統(tǒng)權(quán)限。此外OPC也利用DCOM動態(tài)地打開任意端口，這在防火墻中進行過濾是非常困難的。通用防火墻無法完成對OPC協(xié)議的規(guī)則限制，如果必須需要該協(xié)議，則要求控制網(wǎng)絡、網(wǎng)絡之間必須物理分開，將控制網(wǎng)絡和企業(yè)網(wǎng)絡橫向隔離。
