Data Historians are widely deployed in industrial control environments to record the operational state of the environment. Historians are a time-series database that record the data values of all plant control systems. The recorded information is used to perform analysis of industrial operations to improve efficiency or to help diagnose an issue that occurred. With a historian, plant operators can see the exact state of every control system at any given time. The data captured by historians are used to answer production performance and efficiency-related questions. If a production failure occurs, the state of every element can be viewed just before and just after the incident.
Analog elements such as hydraulic values, temperature sensors, pressure sensors, etc. are controlled by Programmable Logic Controllers (PLCs). PLC registers representing each analog element are used by the controller for command and control. Historians will periodically read the PLC registers over standard protocols such as Modbus, add a time stamp and store the values along with attributes used to define the element. A set of data representing an element is referred to as a data point.
Points are the basic building blocks of a Historian system. Points (sometimes referred to as tags) are created for every element that the Historian System needs to track, representing the status of an analog element performing a function in an industrial environment at an instance in time. Thus, as the name implies, historians provide a historical view of the status of every operational element being tracked.
Tren Pasar
Seiring dengan upaya operasi industri yang terus berupaya mencapai efisiensi yang lebih tinggi, ketergantungan terhadap visibilitas industri di berbagai pabrik akan semakin meningkat guna mendukung pengambilan keputusan bisnis dan menekan biaya. Sistem pencatatan historis akan memainkan peran penting, beralih dari sekadar arsip historis menjadi alat pendukung analisis yang mendekati waktu nyata, sehingga memungkinkan pengelolaan industri yang lebih efisien.
Permintaan yang muncul akan data dalam volume yang lebih besar dan mudah diakses ini dipenuhi oleh vendor sistem pencatatan historis melalui penerapan sistem pencatatan historis berbasis cloud yang aman. Manfaat dari solusi berbasis cloud antara lain pengurangan biaya sumber daya perangkat keras dan perangkat lunak server, ketersediaan sistem yang lebih tinggi, serta skalabilitas dan kinerja yang lebih baik. Peralihan ke cloud juga berfungsi untuk meningkatkan berbagi data dan kolaborasi antardepartemen serta dengan vendor dan penyedia layanan pihak ketiga.
Permintaan untuk mentransfer volume data OT yang lebih besar ke sistem historian berbasis cloud mengharuskan penerapan praktik terbaik keamanan siber, termasuk penerapan Security Gateways untuk membentuk perimeter keamanan elektronik di sekeliling aset kontrol industri.
Transfer Data yang Andal dan Aman Menggunakan MetaDefender Unidirectional Security Gateway (USG) dan BSG
As illustrated in the following diagram, cloud-based historians can aggregate data from multiple distributed industrial control systems, providing a consolidated view of all assets. The data can then be shared across departments and with third parties such as partners or vendors. ICS assets need to be secured from network-borne outside threats by deploying a security gateway at the network perimeter. MetaDefender NetWall security gateway is highly scalable. It can be deployed to protect remote ICS assets or deployed to enforce a plant-wide security perimeter and can be configured to transfer a wide range of data types. MetaDefender Bilateral Security Gateway (BSG) (BSG) supports replicating data from a local historian to the cloud-based corporate historian or can transfer OPC data directly to the cloud historian. MetaDefender NetWall can also connect remote IIoT assets to a cloud historian, transferring OT data over MQTT or OPC.
MetaDefender Bilateral Security Gateway (BSG) mendukung layanan replikasi historian bawaan dari vendor historian terkemuka tanpa memerlukan perangkat lunak antarmuka khusus, sehingga menghilangkan kerumitan penerapan dan beban dukungan yang biasanya diperlukan oleh gateway dan diode lain di pasar.
MetaDefender MetaDefender Bilateral Security Gateway (BSG) was architected to transfer high volumes of data unidirectionally over a non-routable protocol. Through its patent-pending assured delivery architecture, data is reliably transmitted to the destination without requiring retransmission or frequent data backfill operation used by other Gateways and Data Diodes. MetaDefender NetWall also supports data throttling, meaning data is reliably delivered even if there are intermittent network issues. This makes NetWall an ideal solution for securely connecting OT data to cloud-based resources.
Setelah dikonfigurasi, MetaDefender NetWall beroperasi tanpa antarmuka pengguna (headless), sehingga semakin meningkatkan profil keamanannya. OPSWAT merancang MetaDefender NetWall untuk memenuhi tuntutan yang semakin meningkat terkait konvergensi OT/IT, dengan menawarkan tingkat keamanan yang lebih tinggi daripada firewall serta keandalan dan efisiensi biaya yang lebih baik daripada data diode.
