Basically an OS is a set of libraries or functions which programs may use to perform specific tasks relating to interfacing with computer system components (The Computer Technology Documentation Project, n.d.). Advantages and disadvantages exist in every operating system. Reviewed in this paper is a comparison of some of the primary responsibilities of popular operating systems. The review includes Unix/Linux, Mac, and Microsoft Windows operating systems. Memory Management An important function of the OS is to manage the computer systems memory. Programs, processes, and resource do not simply float around in memory haphazardly. Memory is shared among these processes and resources. Accordingly, managed by the OS is an organized structure of locating processes in computer memory locations. The two primary types of memory controlled by an OS are main memory and virtual memory. Main memory is… (need general definition). Virtual (secondary) memory is… (need general definition). Intended memory management requirements include relocation, protection, sharing, logical organization, and physical organization. Processes may...

Computer or data network is a telecommunication network allowing computers to exchange data, files and also allow remote computing, that is, giving authorized users the ability to access information stored on other computers found on the same network. This exchange of data is carried through network links which are established between nodes using either cables or wireless media. Most information in computer networks is carried in packets, thus, increasing the difficulty to manage and secure the network from hazards such as security threats. Undesired packets may easily harm the systems. To counter such infected packets, firewall has been implemented with packet filters which check...

...UNIX /Linux versus MAC versus Windows Paper POS/355 March 11, 2013 Bhupinder Singh UNIX/Linux versus MAC versus Windows Paper Introduction Today we live in a world where technology is the way to go. Even in this century there are people that are still clueless on the operating system. It is different, exciting when a new and advance system comes out. But some of us are so confused when it comes to the basics of new technology. Operating systems are programs which manages the computer’s hardware. The systems provide a basic for the applications programs between the computer user and its hardware. When looking, there are so many different types of operating systems that are available. The four main operating systems that are used are Windows, Mac, UNIX, and Linux. For every computer there are many different items that make the system a whole. When it comes to the different operating systems there are different features available, even though when you think of computers a person might think security will all be the same but there are difference between each one. As you read more you will understand the security and the difference between a MAC, UNIX/LINUX and Windows systems and how each one works. Access control goal is to protect a resource from unauthorized access while facilitating seamless and legitimate use of such resources. Presently, each day users hold the need to access to those resources through a broad line of devices...

...Linux Security Technologies There are many ways to have internet access these days. Coffee shops, libraries, airports and even public buses have free wireless access. With all these free accesses to the World Wide Web, there is also many potential ways for hackers to potentially get your personal information and use it for their gain. There are many ways to combat this situation by using several security measures with Linux programming, which the majority of the software is free. Some of those security technologies are SELinux, TCP Wrappers, IPtables and Chroot Jail to name a few. SELinux is a security enhancement to Linux which allows users and administrators more control over access control. Access can be constrained on such variables as which users and applications can access which resources. Was developed by the NSA in December of 2000. These resources may take the form of files. Standard Linux access controls, such as file modes (-rwxr-xr-x) are modifiable by the user and the applications which the user runs. Conversely, SELinux access controls are determined by a policy loaded on the system which may not be changed by careless users or misbehaving applications. SELinux also adds finer granularity to access controls. Instead of only being able to specify who can read, write or execute a file, for example, SELinux lets you specify who can unlink, append only, move a file and so on. SELinux allows you to specify access to many resources other than files as well, such...

...Robert Hoffman Linux Research 2.1 Security for computers is one of the most important aspects of a system that has to be in place. For this paper I will be writing about four security features that Linux systems use; these are SELinux, chroot jail, openSSH, and iptables. I will briefly describe what they do to provide security. SELinux (security enhanced Linux) was developed by the NSA, who chose Linux as its operating system to create a more secure operating system. Since the development of SELinux by the NSA most Linux distributions now implement SELinux as a standard. Traditional Linux systems use a security called (DAC) discretionary access control. With this approach users and their objects, i.e., files or processes run by the user have the same access as the user. So if an attacker got hold of an admin account they would have complete control over any files or services that account runs or has access to. SELinux uses (MAC) mandatory access control. With this, services and files are controlled by policies saying what may or may not be done. MAC enforces these security policies that limit what users and programs can do. Security threats coming from user errors, attackers, or software problems are limited by MAC. SELinux has three modes that it can function in: Enforcing- This is the default state where SELinux security policy is enforced, anything not permitted by the security policy can not be done. Permissive-...

...UNIX, Linux, Mac, and Windows OS Comparison Paper B. James Bryant UNIX, Linux, Mac, and Windows OS Comparison In 1956, General Motors produced the first OS for its IBM 704 series mainframe. Since then companies around the world, both big and small, have been tirelessly researched, testing, and releasing newer and faster operating systems for the world to use. Among these are systems developed by/for UNIX, Linux, Microsoft, and Apple. In fact, it’s safe to say that these four companies have a monopoly on all current technology used in both the military, corporate, and private sectors all around the world. UNIX Operating System Unix operating systems have the ability to be multi-user, multi-tasking and portable. Multi-user capabilities are accomplished through time sharing which means the processor allocates slices of time to first one process and then the next, sharing the available time in sequence with waiting processes (Nagpal, 2009). Unix can run in either command line interface, CLI, or graphic user interface or GUI mode. A key and unique feature of Unix is that it has a modular design which allows parts of the system to be added or removed without affecting performance of the other parts making Unix systems highly customizable. Unix operating systems have four core components, (1) the kernel, (2) the shell, (3) the file system, and (4) the utilities or tools and applications (Love et al, 2005). The kernel is the lowest layer of the operating system that...
