Operating Systems are complex pieces of software that are designed for powerful hardware, easily capable of running many programs at once, the prioritize hardware task requests known as ‘system calls’ and allocate them memory space or processing time as needed.

In our world today there are so many different types of operating systems as well as features and applications that run on them. There are many similarities as well as differences between Windows 7, Linux and Windows Server 2008. The one enduring similarity is that all three are intended to be utilized as an operating system is meant to.

One of the important part of system administration should be secure, so it is very important to understand which factors can affect security inside and outside our system. There are many key decisions that have to be made, for example, what server operating system should a system use to which

As basic users, security is one feature that most of us overlook when it comes to operating systems until it is too late. In this paper we will discuss the security flaws within the Windows Operating system, and then discuss countermeasures to fix the system flaw.

1. The relative advantages and disadvantages of at least three different measures used to protect operating systems.

The original release of Ubuntu used the GNOME desktop which was user friendly and robust but later released a KDE version known as Kubuntu as well which resembled more of a windows type environment as well as a server edition. In recent years Ubuntu has broken through the standard and has become heavily used on net books and cloud systems as lightweight yet robust platforms.

Microsoft has been the world leader with respects to computer Operating Systems Software, and has increasingly become more efficient and precise with each release. Microsoft released their first version of the Windows Software (November 20th, 1985). This operating system was an anomaly at the time, and has progressed to the point that it is used worldwide on most computers in the world. All of the leading competitors have used Windows as a benchmark and have either copied its features or expanded upon them.

As such, he introduces a technique of identifying a spectrum of potential vulnerabilities and suggests procedures to deal with them. Systems Specification and High Order Language Implementation are categorized as items of high risk to attacks. Security Policy and Machine Language Implementation are classified as items of moderate risk of being vulnerable to attacks. Circuits Electronics and Device Physics are of low and very low risks respectively. He also discusses potential threats such as deceiving operating systems to grant access to file or data to unauthorized users through direct (overt) and indirect (convert) channels. Walker also says that lack of precise definition of trusted operating systems and the higher cost of building them are the significant drawbacks faced by the vendors. Vendors are concerned that if they build trusted operating systems, they might not be accepted by their customers. The only solution suggested by the author was to have someone or a company builds it, shares the technology used, and convinces the general public on the significance of it. Once it becomes accepted, then there will be a widespread use of trusted computer operating systems.

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

While of a similar flavor to that of Windows 7 Ubuntu is a Debian based desktop distribution. Ubuntu is a good general desktop application geared more toward graphic multimedia usage. Ubuntu also has the ability to run some Microsoft programs such as Microsoft Office through the use of a software program called wine which allows Linux like operating systems to run windows applications.

The operating system is an extremely crucial type of system software. It is the backbone of a computer. Without an operating system, our computers will not function properly. Operating systems are highly skilled software that includes programs with an ample amount of information. This information provided from these programs makes it easier for applications to communicate with the hardware. Linux and Windows are two operating systems that dominate in our society today. They are not only dominating in our society, but also in the business world. Windows and Linux are the two most popular

Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed by the user even if the company fails [1]. Moreover, updates for Linux are available every six months [1]. Nowadays, Linux is in constant development by

Three operating systems discuss in this paper each have their advantages and disadvantages from one another. The biggest advantage for Microsoft is the widespread use and compatibility with most every type of program out there. If you 're a Linux fan then you appreciate not only the price which is usually free but also that it is

What is Operating System Security, Operating system security is the process of ensuring OS integrity, confidentiality and availability also OS security refers to specified steps used to protect the OS from threats, viruses, worms, malware or remote hacker. OS security include all avoiding-control techniques, which safeguard any computer information from being stolen, edited or deleted if OS security is included. OS security allows different applications and programs to perform required tasks and stop unauthorized interference. OS security may be applied in many ways. We 're going to discuss following topics in this article. A brief description about security and what are the types of encryption and what is Authentication, One Time passwords, Program Threats, System Threats and Computer Security Classifications.

The information technology field is a field that covers a vast amount of technologies and ideas that have evolved to be much more than what they were during the infancy of the technology movement. Perhaps the greatest innovator and most recognizable face of the field is Bill Gates, the creator of the Windows operating system. Windows revolutionized the way the public interacted with their personal computers and catapulted the devices into the majority of American’s homes. Running counter to Windows, and taking a completely open source route for ease of access and distribution is Windows rival Linux. Linux has a very different approach to how the PC should operate and had a number of different versions that are tailored to individual user’s needs. All of these different operating systems have at least one thing in common however. The ability to run on a personal computer. The personal computer, or PC, the personal computer is a general-purpose computer that make it useful for individuals and are intended to be operated by an end user.
