Dr. Sándor Kürti (born 1947) graduated in 1971 from the University of Veszprem (Hungary) on the faculty of Chemistry Process Automation.
 In 1975 he obtained diploma in system manager engineering, and received doctor’s degree from mathematical statistical analysis.
 After his graduation he worked for the Danubian Oil Refinery.
 His fields were: implementation of computer control system at gasoline mixing unit, design of the process control system of a catalic crack plant.
 Later on he joined the International Research Institute MNIIPU (Moscow, SU) where he dealt with mathematical simulation of blending systems.
 Working for Honeywell, (Bracknell, UK) he simulated process control system of a catalytic crack plant.
 In 1989 he founded .
 KÜRT developed a hard disk repair technology, a world-renowned data recovery technology, as well as IT security technology and methodology.
 He was awarded Kalmar Laszlo Award for the data recovery technology in 1995, Information Technology Manager of the Year in 1997, 1998, Gabor Denes Award for Innovation in 1998.
 He is vice president of IVSZ (Hungarian Association of IT Companies).
 In 2004 he was decorated with the Széchenyi Prize for his exceptionally high standard, exemplary, internationally acknowledged accomplishments.
 He has been elected as a member of the Stakeholder Group of the European Union's data security organization (ENISA).
 In 2005 he was given Ernst & Young “Entrepreneur Of The Year 2004” international business award for his creativity, for his personal contribution to the accomplishment of innovative ideas, and his success in creating a model organizational culture at KÜRT Co.
 The KÜRT Co. received the ‘Family Friendly Workplace Prize 2005’ in the medium-sized enterprises category.
 In 2006 Dr. Sándor Kürti was the first representative of the Hungarian business community to participate in selecting the world’s best entrepreneur at The “World Entrepreneur Of The Year” contest organised by Ernst&Young.
 In 2007 he was given the Pro Information Technology Award by the Hungarian Association of IT Companies.
OS/360, officially known as IBM System/360 Operating System, is a discontinued batch processing operating system developed by IBM for their then-new System/360 mainframe computer, announced in 1964; it was heavily influenced by the earlier IBSYS/IBJOB and Input/Output Control System (IOCS) packages.
 It was one of the earliest operating systems to require the computer hardware to include at least one direct access storage device.
Special Real Time Operating System (SRTOS) is a discontinued IBM real time operating system, originally designed for use in the electricity industry, but later also applied in other areas of industrial process control.
 It formed part of the Realtime Plant Management System (RPMS) and Advanced Control System (ACS).
 Rather than a standalone operating system, it was designed as an extension to the OS/VS1 and OS/VS2 (later MVS) operating systems.
 It was also used in the paper industry.
 SRTOS was originally released in 1976, but continued to be used through the 1980s.
In our modern society, computerized or digital control systems have been used to reliably automate many of the industrial operations that we take for granted, from the power plant to the automobiles we drive.
 However, the complexity of these systems and how the designers integrate them, the roles and responsibilities of the humans that interact with the systems, and the cyber security of these highly networked systems has led to a new paradigm in research philosophy for next generation control systems.
 Resilient Control Systems consider all of these elements and those disciplines that contribute to a more effective design, such as cognitive psychology, computer science, and control engineering to develop interdisciplinary solutions.
 These solutions consider such things such as how to tailor the control system operating displays to best enable the user to make an accurate and reproducible response, how to design in cyber security protections such that the system defends itself from attack by changing its behaviors, and how to better integrate widely distributed computer control systems to prevent cascading failures that result in disruptions to critical industrial operations.
 In the context of cyber-physical systems, resilient control systems are an aspect that focuses on the unique interdependencies of a control system, as compared to information technology computer systems and networks, due to its importance in operating our critical industrial operations.
Linus Benedict Torvalds ( ; ] ; born December 28, 1969) is a Finnish-American software engineer who is the creator, and for a long time, principal developer of the Linux kernel, which became the kernel for operating systems such as the Linux operating system, Android, and Chrome OS.
 He also created the distributed revision control system Git and the diving logging and planning software Subsurface.
 He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel".
 He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award.
Enea develops and delivers software and expert services for companies that develop communication-intensive products for the connected society.
 As a vendor of real-time operating systems to the world's largest Tier-1 telecom equipment manufacturers (TEMs) and network equipment manufacturers (NEPs), Enea has decades' worth of experience from mobile infrastructure and the real-time domain.
 Enea, which is an abbreviation of "Engmans Elektronik Aktiebolag", is producing the operating system OSE (Operating System Embedded).
 Enea is global information technology company with its headquarters in Kista, Sweden
Multi categories security (MCS) is an access control method in Security-Enhanced Linux that uses categories attached to objects (files) and granted to subjects (processes, ...) at the operating system level.
 The current implementation in Fedora Core 5 is advisory because there is nothing stopping a process from increasing its access.
 The eventual aim is to make MCS a hierarchical mandatory access control system.
 Currently, MCS controls access to files and to "ptrace" or "kill" processes.
 It has not yet decided what level of control it should have over access to directories and other file system objects.
 It is still evolving.
The Operating System Embedded (known by the acronym Enea OSE) is a real-time embedded operating system created by the Swedish information technology company ENEA AB.
 Bengt Eliasson, who at the time was a consultant from ENEA with an assignment at Ericsson, wrote the basic parts of the kernel.
 The early version for the Zilog Z80 processor was named OS80.
Group Control System (GCS) is an operating system made by IBM, meant to run as a guest of VM.
 GCS is an integral component of the discontinued VM/SP (since VM/SP 4), VM/XA SP, VM/ESA and current z/VM IBM System product offerings.
IBM (International Business Machines Corporation) is an American multinational technology company headquartered in Armonk, New York, United States, with operations in over 170 countries.
 The company originated in 1911 as the Computing-Tabulating-Recording Company (CTR) and was renamed "International Business Machines" in 1924.
