The Multics Operating System Project Undertaken At The Massachusetts Institute Of Technology

The National Security Agency “coordinates, directs, and performs highly specialized activities to protect U.S. government information systems and produce foreign signals intelligence information” (http://www.nsa.gov/about/index.cfm). Without the NSA the systems of the government would not be able to function as well as it does. The NSA has been with computer security research, investigating a variety of security topics. This system helping the government must be able to separate information between confidentiality and integrity to help provide system security. An operating system security mechanism makes the separation between the two. Unfortunately, many operating systems the security features to make the separation. Since many systems lack the ability to

Windows XP was based on Windows NT4 and Windows 2000 technology. Microsoft was positioning the Windows XP Professional Edition to replace Windows NT4 and Windows 2000 Professional. In addition, the Windows XP Home edition replaced Windows 95/98/ME (TechGenix Ltd., 2002). The gap between the Home and Professional Editions begins to widen when it comes to larger computer networks. Some of the features that are limited to the Professional Edition are Remote Desktop, Offline Files and Folders, Scalable Processor Support, Encrypting File System, Access Control, Designed to manage Microsoft Windows Servers, Centralized Administration, Group Control, Software Installation and Maintenance, Roaming User Profiles, and Remote Installation Service.

Microsoft Windows has evolved into an operating system that is very reliable and dependable when it comes to getting task done on a daily basis when a computer system is needed. “In 1975, Gates and Allen form a partnership called Microsoft. Like most start-ups, Microsoft begins small, but has a huge vision—a computer on every desktop and in every home” (Microsoft.com). In this paper I will discuss the history of Microsoft’s Operating systems and security features available during each stage of advancement over the years.

The article, which addresses security loopholes in modern computing environments, by Loscocco et al highlights what is and has been being done security wise in the past and how secure these implementations were and going forward what should be done to ensure in depth security which guarantees system wide security (1998). The article first explains features of secure operating system and why current systems implemented under the notion of application space security ultimately failed to safe guard the integrity and confidentiality of our assets. The article then continued with general examples of access control and cryptography implemented in the application space with no or little support from operating system and showed their vulnerabilities to attacks such as tampering, bypassing and spoofing. The article supplied real-life examples to support the evidence that building security in the application space without secure operating system is meaningless. The article raised concrete examples on mobile code security, Kerberos network authentication service, IPSEC and SSL network security protocols and firewall. The paper finally put an interesting remark that security implemented in application space without secure operating system is like “building a house in a pile of sand” and it also emphasized that secure operating system without better security on the

Multikernel is a new distributed OS system architecture that treats the machine as an independent cores communicate via message passing.

An operating system is a vital component of the computer system. The common and simple devices like refrigerators and microwave ovens does not have an operating system. The complex systems which handle several components, functions and processes usually have an operating system. The operating system is like the brain of a human being, the brain is an essential organ in the body of human being which sends signals and helps functioning of the human body. Our intelligence, attitude, emotions and senses defines our presence, all these are possible because of our brain. In similar manner, “Operating System” (OS) is the power behind a computer system. In other words, operating system is brain of the computer and processor is the heart of the computer. A computer is the concatenation of several hardware parts. The operating system manages computer hardware resources and provides common services for computer programs and other application software.

This section of paper includes why we need cloud computing as a security control tool against the cyber criminal activities and in how many ways it can be implemented. As we are living in a technical era, many aspects of our lives rely on the Internet and computers, including transportation, communications, government, medicine, finance and education. Consider how much of our personal information is stored either on our own computer or on someone else’s system.

Organizations are beginning to realize that using outdated mainframes is no longer a viable pathway for meeting their data needs. This in turn has given way for the development and use of Cloud Computing. According to Fee (2013), the “history of the cloud dates back as far as the 1950s” with the concept of “timesharing,” in which several computers within an organization would share one giant “mainframe” computer (Fee, 2013, A brief…, para. 1). This eventually led to the creation of “ARPANET (Advanced Research Projects Agency Network)” by “J.C.R. Licklider,” who hoped “that someday everyone would be able to access data and programs from any location” (Fee, 2013, A brief…, para. 2). Suffice to say, Licklider’s dreams are now a reality as

Several higher-education institutions have implemented or used private and public clouds that add value to their academic environments related to areas that need the distribution of computer programs in networked environments such as network programming [2], Systems Administration [6], Security [6] [12], data processing [11]. In this regard, a number of

Modern day computing systems rely on a distributed system for data, functions and services. Arguably all popular software such as Uber, Spotify, Facebook and Fitbit among others, host their data and applications on dedicated servers to allow for user access services through their devices. The challenge with server based systems is that the integrity and security of private data is left out to third parties, nowadays established as corporations who offer hosting services for applications database and file storage. The main advantage of cloud based models is that customers do not have to pay for the installation of data storage and processing capabilities for applications (Jadeja,

Operating systems, applications, databases, and other types of information processing systems are the core element for all business operations all through the private and public sector environments. Because no information system is bulletproof, nor is there any way to ensure complete safety while using any type of electronic device it is essential to practice vigilance at all times. Viruses, Trojans, worms, and other malicious tools are used daily by hackers at an attempt to compromise sensitive data and integrity of information systems. Without stable, secure applications and operating systems that have been updated with the latest patches, and tested for durability to provide a secure computing environment, the
