單對(duì)以太網(wǎng)部署的一些早期應(yīng)用利用了以太網(wǎng)-APL 聯(lián)盟所做的工作，該聯(lián)盟已將單對(duì)以太網(wǎng)物理應(yīng)用到工業(yè)過(guò)程應(yīng)用中。利用該聯(lián)盟所做的工作，客戶可以開(kāi)始對(duì)他們的 HART、基金會(huì)現(xiàn)場(chǎng)總線和 PROFIBUS 現(xiàn)場(chǎng)總線安裝進(jìn)行未來(lái)驗(yàn)證。當(dāng)前部署上述系統(tǒng)的客戶可以輕松驗(yàn)證他們的系統(tǒng)是否已為單對(duì)以太網(wǎng)做好了性能準(zhǔn)備，并為將來(lái)將系統(tǒng)升級(jí)到 HART-IP、Foundation Fieldbus HSE 或 PROFINET 掃清了道路。
威猛 (Vermeer) 表示，其他串行密集型自動(dòng)化應(yīng)用，例如在樓宇自動(dòng)化中使用 BACnet MS/TP，對(duì)于這項(xiàng)面向未來(lái)的努力也已經(jīng)成熟。通過(guò)將串行和模擬電纜規(guī)格升級(jí)到滿足 TIA 或 IEC 單對(duì)以太網(wǎng)要求的規(guī)格，樓宇業(yè)主和運(yùn)營(yíng)商可以確信他們的物理基礎(chǔ)設(shè)施已準(zhǔn)備好支持下一代智能樓宇設(shè)備。
“單對(duì)以太網(wǎng)將以太網(wǎng)帶到了邊緣，同時(shí)解決了阻礙以太網(wǎng)全面采用的幾個(gè)問(wèn)題，取代了串行和模擬網(wǎng)絡(luò)。單對(duì)以太網(wǎng)的基本功能提供超過(guò) 1 公里的通信，是標(biāo)準(zhǔn)以太網(wǎng)距離的 10 倍，”維米爾說(shuō)。“單對(duì)以太網(wǎng)做到了這一點(diǎn)，同時(shí)提供 10 Mb/s 的帶寬，是現(xiàn)場(chǎng)總線協(xié)議提供的帶寬的 300 倍。此外，通過(guò) Ethernet-APL 聯(lián)盟，單對(duì)以太網(wǎng)解決了將以太網(wǎng)帶入爆炸危險(xiǎn)環(huán)境的挑戰(zhàn)。借助 Ethernet-APL 的這種功能，設(shè)備可以在以太網(wǎng)上運(yùn)行，而無(wú)需在這些環(huán)境中進(jìn)行 2 對(duì)或 4 對(duì) IP 連接所需的重要保護(hù)措施。”
網(wǎng)絡(luò)安全的重要性
IT-OT 強(qiáng)調(diào)靈活和安全的訪問(wèn)
西門子網(wǎng)絡(luò)安全產(chǎn)品負(fù)責(zé)人 Sophie Richerzhagen 告訴 IEB，關(guān)鍵技術(shù)趨勢(shì)正日益伴隨著網(wǎng)絡(luò)安全對(duì)行業(yè)日益重要的重要性。
“這一領(lǐng)域已經(jīng)在影響工業(yè)市場(chǎng)中設(shè)備和服務(wù)的發(fā)展，而且在過(guò)去 24 個(gè)月的移動(dòng)辦公爆炸式增長(zhǎng)中加速了這一進(jìn)程。在辦公/IT（信息技術(shù)）領(lǐng)域，移動(dòng)辦公早已確立，但對(duì)更靈活、更安全地訪問(wèn)運(yùn)營(yíng)技術(shù) (OT) 中的系統(tǒng)和應(yīng)用程序的需求也在不斷增長(zhǎng)，”Richerzhagen 表示。
在企業(yè)范圍內(nèi)訪問(wèn)工業(yè)應(yīng)用程序的好處已經(jīng)對(duì)解決 OT 和 IT 的不同要求的網(wǎng)絡(luò)安全解決方案的需求不斷增加。在 IT 領(lǐng)域，零信任安全模型已被證明對(duì)具有動(dòng)態(tài)設(shè)備池的網(wǎng)絡(luò)有效；每個(gè)用戶和設(shè)備都必須不斷證明其身份和完整性的概念，無(wú)論是否在網(wǎng)絡(luò)邊界內(nèi)。相比之下，根據(jù) IEC 62443 作為深度防御的一部分，基于邊界的工業(yè)安全概念用于保護(hù)具有多年來(lái)發(fā)展的工業(yè)通信網(wǎng)絡(luò)的 OT 系統(tǒng)。
工業(yè)自動(dòng)化領(lǐng)域的供應(yīng)商西門子和零信任領(lǐng)域的供應(yīng)商 Zscaler Inc. 擴(kuò)展了深度防御 OT 概念，使其進(jìn)一步受到零信任原則的保護(hù)。結(jié)合現(xiàn)有的 OT 安全機(jī)制，這允許實(shí)現(xiàn)細(xì)粒度訪問(wèn)概念。
“有了這種基本保護(hù)，公司可以基于現(xiàn)有技術(shù)提供新產(chǎn)品和服務(wù)。例如，西門子內(nèi)部的安全 IT/OT 集成為制造業(yè)提供了對(duì) X 射線檢測(cè)系統(tǒng)的遠(yuǎn)程訪問(wèn)，以加快診斷速度。同樣，質(zhì)量保證工程師也可以進(jìn)入他們的操作制造過(guò)程，以進(jìn)行預(yù)防性檢查或更快地解決嚴(yán)重問(wèn)題。工業(yè)網(wǎng)絡(luò)安全正在支撐工業(yè) 4.0 帶來(lái)的更大數(shù)字化用例，”Richerzhagen 補(bǔ)充道。

“Single Pair Ethernet brings Ethernet to the edge, while addressing several issues that have prevented full-scale adoption of ethernet, replacing serial and analog networks. The base capability of Single Pair Ethernet provides for communication over 1Km, 10x the distance of standard ethernet,” Vermeer said. “Single Pair Ethernet does this while providing 10 Mb/s, 300x the bandwidth offered by fieldbus protocols. Also, through the Ethernet-APL consortium Single Pair Ethernet addresses the challenge of bringing ethernet into explosion hazard environments. With this capability of Ethernet-APL, devices can be operated over ethernet without the significant protection measures that would otherwise be required for 2- or 4-pair IP connections in these environments.”
Importance of cybersecurity
IT-OT emphasis on flexible and secure access
Sophie Richerzhagen, Product Owner – Cybersecurity for Siemens, told IEB that key technical trends are increasingly accompanied by the growing importance of cybersecurity for industry.
“This field is already influencing the development of devices and services in the industrial market, and has only been accelerated by the mobile working explosion from the last 24 months. In the office/IT (Information Technology) world, mobile working in general has long been established, but there is also a growing demand for more flexible and secure access to systems and applications in operational technology (OT),” Richerzhagen stated.
The benefits of enterprise-wide access to industrial applications have created an increasing demand for cybersecurity solutions that tackle the different requirements of OT and IT. In IT, the Zero Trust security model has proved effective for networks with dynamic pools of devices; a concept in which every user and device must continuously prove their identity and integrity, whether within the network perimeter or not. In contrast, the perimeter-based industrial security concept as part of Defense-in-Depth according to IEC 62443 is used to protect OT systems with industrial communication networks that have grown over years.
Siemens, a leading provider in the field of industrial automation, and Zscaler Inc., a leading provider in the field of Zero Trust, have expanded the Defense-in-Depth OT concept to be additionally secured by Zero Trust principles. In combination with the existing OT security mechanisms, this allows implementation of a granular access concept.
“With this fundamental protection, companies can offer new products and services based on their existing technology. For instance, secure IT/OT integration within Siemens has provided manufacturing with remote access to X-ray inspection systems for faster diagnostics. Similarly, quality assurance engineers can also tunnel into their operative manufacturing processes for preventative inspection or faster resolution of acute issues. Cybersecurity for industry is underpinning the larger digitalization use-cases that Industry 4.0 has brought to the forefront,” Richerzhagen added.
