SCADA merupakan singkatan dari Supervisory Control and Information Acquisition. SCADA merupakan sebuah sistem yang mengumpulkan informasi atau information-data dari lapangan dan kemudian mengirimkan-nya ke sebuah komputer pusat yang akan mengatur dan mengontrol data-data tersbut. Sistem SCADA tidak hanya digunakan dalam proses-proses industri, misalnya, pabrik baja, pembangkit dan pendistribusian tenaga listrik (konvensional maupun nuklir), pabrik kimia, tetapi juga pada beberapa fasilitas eksperimen seperti fusi nuklir. Dari sudut pandang SCADA, ukuran pabrik atau sistem proses mulai dar 1.000an hingga 10.000an I/ (luara/masukan), namun saat ini sistem SCADA sudah bisa menangani hingga ratusan ribu I/.
Distributing intelligence in this manner also delivers a safeguard in case there’s an interruption in the operation of a single of the principal controllers. The brain can be instructed to continue to record measurements and carry out calculations, and operators can continue to view this information from the handle center’s HMI. And you can count on Dateline, Twenty-Twenty, 60 Minutes and Prime Time Live to all compete for the very first exclusive interview with Benjamin Franklin’s landlady on the excellent doctor’s most up-to-date dalliance.

Initially the attacker may well deploy a self-executable malware, which operates with no guidelines from the attacker. In the subsequent phase the malware successfully compromises the firewall between the SCADA and the corporate IT networks, and then it could communicate with the attacker to acquire new tasks for damaging the technique. Even worse are reports that use smoothed-more than information with analytics that are a small too smug to infer points like a user’s political affiliation.
Piping and instrumentation diagrams (P&ID) show the approach. Further information is needed for the specification of the approach control and safety systems design and style and their manage logic. These consist of: Loop diagram, Instrument datasheet, Cable schedule and Termination list. These are all problems, difficulties, what ever. If this is what takes place with each other with turf wars, mutual distrust, conflicting objectives and so on, why would anyone ever want to Integrate SCADA and IT.
All these areas of integration have their personal problems. The main difficulties relate to the differing standards SCADA and IT use. These are resolvable, but they add complexity to a SCADA project. The added benefits far outweigh the charges, but to realise these rewards a extended tradition of separate improvement should be overcome. Zero-danger bias – Preference for minimizing a modest risk to zero over a greater reduction in a larger risk.
