It is the result of two diploma works at Linköping University to complete studies for Bachelor of Science in Electrical Systems Engineering and Bachelor of Science in Media and Communication Engineering. To prepare this thesis has been very instructive and we want to thank Måns Östring, our examiner at the university and everyone at Siemens that helped us in this work: Peter Alm, instructor at Siemens, Thomas Schuh, technical assistance in Germany for invaluable help, Mikael Andrén, Erik Hägg and Erik Wiklund. Sammanfattning Företaget Siemens Industrial Turbomachinery AB producerar och driftsätter bland annat gasturbiner, ångturbiner och kompressorer, samt utför service för komponenter till värme- och kraftproduktion. Siemens bedriver också forskning, utvecklingsarbete, marknadsföring, försäljning och installationer av turbiner och kompletta kraftverk samt inspektioner och maskinunderhåll. Vårt examensarbete har varit att ta fram en automatiserad statuslogg som ska användas som ett hjälpverktyg för att kontrollera status före och efter en serviceåtgärd på en gasturbin. Driftstörningar ska registreras på ett strukturerat sätt för att få en bra möjlighet för uppföljning av tillförlitligheten på anläggningen. En automatisk loggningsfunktion har utvecklats, som aktiveras vid start, stopp och tripp av kontrollsystemet. Loggfiler med namn av händelse, datum och tid skapas automatiskt. De uppgifter som loggas är händelsedatum och tid, signalnamn, mätvärden och mätenheter på de signaler som ska analyseras av supportpersonalen. Med hjälp av loggfilerna kan de göra en bedömning av felorsaken. Abstract The Company Siemens Industrial Turbo Machinery AB manufactures and launches in operation among other things gas turbines, steam turbines, compressors, turn-key power plants and carries out service for components for heat and power production. Siemens also performs research and development, marketing, sales and installations of turbines and completes power plants, service and refurbish. Our thesis for the engineering degree is to develop an automatic status log which will be used as a tool to control how the status of the machine is before and after technical service at gas turbines. Operational disturbances will be registered in a structured way in order to get a good possibility to follow up the reliability of the application. An automatic log function has been developed and will be activated at start, stop and shutdown of the turbine system. Log files are created automatically and get a name with the event type, the date and the time. The files contain data as timestamp, name, measured values and units of the signals which are going to be analyzed by the support engineers. They can evaluate the cause of the problem using the log files.

  • Stuxnet Virus
    Sarah Walterman, Liz Ottati, Hamad Mohammed Business Information Systems- Cybersecurity Term Project Stuxnet Virus The Stuxnet Virus was discovered in June 2010; however, it is said that the development started as early as 2005. It is a “500-kilobyte computer worm that infected the software of at least 14 industrial sites in Iran.”9 Malware exists in many forms, that is, worms, scareware, Trojans, spyware, and adware. Each of these programs has a unique way of compromising the way a computer functions. Over the years, there have been malware programs reported as threats to networks. As an instance, Stuxnet is one such malware existing in PCs. While it’s not known exactly who created Stuxnet, the most realistic guess is that the United States and Israel worked together to make it. The original purpose was to “derail, or at least delay, the Iranian program to develop nuclear weapons.”8 Most worms are created to just infect a computer, but Stuxnet was created to cause “real-world physical effects.”8 Developers of the malware made it in such a way that it attacks devices that meet a specific requirement. The worst-hit country was Iran. The state's top companies, especially those dealing with uranium infrastructure, were infected by Stuxnet.10 Stuxnet is believed to be spread using flash drives. “Stuxnet, as it came to be known, was unlike any other virus or worm that came before. Rather than simply hijacking targeted computers or stealing information from them, it escaped the digital realm to wreak physical destruction on equipment the computers controlled.”6 It was programmed to make the nuclear plant’s centrifuges spin faster than they were meant to and it eventually destroys them.

  • The History of Stuxnet: Key Takeaways for Cyber Decision Makers Military Category Cyber Conflict Studies Association
    The History of Stuxnet: Key Takeaways for Cyber Decision Makers Military Category Cyber Conflict Studies Association - Call for Papers June 4th, 2012 The History of Stuxnet – Key Takeaways for Cyber Decision Makers 1 History is the witness that testifies to the passing of time; it illuminates reality, vitalizes memory, provides guidance in daily life and brings us tidings of antiquity. — Cicero Introduction In each profession and aspect of daily life there are decision makers who guide from their area of influence. These decision makers exist at every level of civilian and military leadership. It is through their choices, and the understanding of their choices’ impacts, that a nation collectively moves forward. This forward movement also exists in the development of the cyberspace domain. Cyber decision makers dictate tactical and strategic level choices to include capability development, employment, and overall strategies. It is by these choices that the cyberspace domain acts as a national level projection of power. The projection of power through offensive and defensive strategies in cyberspace offers unique challenges compared to the other warfighting domains due to its comparative youth. As a relatively new domain it is imperative to understand the history of key cyber events so that modern day decision makers can capitalize on the lessons learned. It is in this way that the best choices for the vectoring of the domain will present themselves. The Stuxnet cyber attack on the Iranian nuclear enrichment facility at Natanz is seen by many as the first true cyber weapon.1 This makes Stuxnet’s importance as a cyber event unparalleled in modern cyber history and specifically worth understanding.
