通信技術(shù)的進步使得大規(guī)模HMI/SCADA系統(tǒng)在許多行業(yè)應用中獲得了成功。系統(tǒng)內(nèi)存在兩個級別的通信——信息技術(shù)(IT)和現(xiàn)場，這兩個級別的通信在安全級別上有顯著差異。

HMI/SCADA系統(tǒng)的組件是模塊化的，不僅允許簡單的故障檢修，而且分配計算負荷和消除單點故障。通過基于以太網(wǎng)的內(nèi)部網(wǎng)絡將多個胖、瘦、web和移動運行時客戶端連接到主HMI/SCADA服務器中心并不罕見；然而，在某些情況下，系統(tǒng)也可能使用外部租用線路、調(diào)制解調(diào)器、無線、蜂窩或衛(wèi)星技術(shù)。主HMI/SCADA服務器中心還包括多個網(wǎng)絡服務器，用于分配負載、確保正常運行時間和存儲大量數(shù)據(jù)。由于這些組件都以某種方式聯(lián)網(wǎng)，它們使用標準化的通用協(xié)議來傳輸數(shù)據(jù)，所有這些數(shù)據(jù)在很大程度上都是不加密的，需要弱認證或不需要認證。

字段:HMI/SCADA實施通常由許多具有控制或數(shù)據(jù)收集功能的廣泛分散的遠程站點組成，所有站點都連接到中央控制和監(jiān)控點。數(shù)據(jù)必須通過網(wǎng)絡(可以是光纖、電話或無線)在控制室和遠程終端單元(RTU)之間傳遞，并且用于傳遞該數(shù)據(jù)的協(xié)議經(jīng)常被開發(fā)為強調(diào)可靠性和易于實現(xiàn)而不是安全性。

現(xiàn)代計算設施已經(jīng)使得安全實用的加密幾乎不可能抵御堅定的黑客，因此設備之間的通信需要采用多層防御，其主要目的是使對數(shù)據(jù)的訪問變得困難并檢測數(shù)據(jù)是否已經(jīng)被破壞。

Advances in communication technology have made large-scale HMI/SCADA systems successful in many industry applications. There are two levels of communication within the system – information technology (IT) and field – which differ significantly in the level of security.

The components of the HMI/SCADA system are modular, not only allowing for simple troubleshooting, but also distributing compute loads and eliminating single points of failure. It is not uncommon to connect multiple fat, thin, web, and mobile runtime clients to a primary HMI/SCADA server hub via an Ethernet-based internal network; However, in some cases, the system may also use external leased line, modem, wireless, cellular, or satellite technology. The primary HMI/SCADA server center also includes multiple network servers for distributing load, ensuring uptime, and storing large amounts of data. Since these components are all networked in some way, they use standardized common protocols to transmit data, all of which are largely unencrypted and require weak or no authentication.

HMI/SCADA implementations typically consist of many widely dispersed remote sites with control or data collection functions, all connected to a central control and monitoring point. Data must be passed between the control room and the remote terminal Unit (RTU) over a network (which can be fiber optic, telephone, or wireless), and the protocols used to deliver this data are often developed to emphasize reliability and ease of implementation over security.

Modern computing facilities have made secure and practical encryption almost impossible to defend against determined hackers, so communication between devices requires multiple layers of defense, the main purpose of which is to make access to data difficult and detect whether the data has been compromised.
