Cyber Security in Material Manufacturing

Öz

1.1.1           Industry 4.0, a new industry revolution, is happening now and several developed countries are leading the path. Internet of things (IoT) is also encompassed by Industry 4.0. In the future, more devices in factories are to be connected to Ethernet or Internet. However, this makes the companies, devices and researchers vulnerable to cyber-attacks. Recently, some cyber-attacks which have happened to some companies or countries verify the danger. Sintering systems and furnaces are used for research by universities and for series manufacturing by factories. Arc furnaces and induction furnaces are also commonly used devices in metal factories. A sintering system, an arc furnace or an induction furnace which is connected to Internet or Ethernet may also be under cyber-attack threat. The danger may be prevented by taking necessary precautions. In this study, these three-production systems are first briefly introduced and then inspected assuming that they have been connected to internet and examined with considering cyber-attack point of view. Some basic solutions against cyber-attacks to the aforementioned devices are suggested.

Yeni bir endüstri devrimi olan Endüstri 4.0 günümüzde yaşanmakta ve özellikle bazı gelişmiş ülkeler bu alanda öncü çalışmalar ortaya koymaktadır. Nesnelerin İnterneti (IoT) Endüstri 4.0 tarafından kapsanan önemli bir altyapıdır. Gelecekte, fabrikalardaki daha fazla cihazın Ethernet veya İnternet üzerinden çalışmalarını sürdürmesi öngörülmektedir. Bunun kurum ve fabrika ortamındaki cihazları ve verileri siber saldırılara karşı savunmasız bırakabileceği açıktır. Son zamanlarda, farklı ülkelerden farklı kurumlarda yapılan bazı siber saldırılar tehlikeyi doğrulamaktadır. Çeşitli malzeme sinterleme sistemleri ve fırınlar üniversiteler tarafından araştırma yapmak ve fabrikalar tarafından seri imalat yapmak için kullanılırlar. Ark fırınları ve endüksiyon fırınları da metal fabrikalarında yaygın olarak kullanılan cihazlardır. Internet veya ethernet'e bağlı bir sinterleme sistemi, bir ark ocağı veya bir indüksiyon ocağı da siber saldırı tehdidi altında olabilir. Bu noktada gerekli önlemler alınarak tehlike önlenebilir. Bu çalışmada, bu üç üretim sistemi ilk öncelikle kısaca tanıtılmış ve daha sonra internete bağlı oldukları dikkate alınarak siber saldırı bakış açıları ile incelenmişlerdir. Çalışmada, belirtilen cihazlara karşı olası siber saldırılara yönelik çözümler önerilmektedir.
