...Comparison between the UNIX and the Windows 2008 servers Instructor Keating ECPI University CIS305 Advanced UNIX Administration June 15, 2013 There are many reasons that I choose this speaking about the UNIX server verses the Window 2008 server but mainly it was the fact that I had no idea how this server worked and why it was so important. At first when I heard of UNIX it didn’t seem important at all in fact all I could remember is that it was the server that carried the weird names. Then I learned that this was the Linux server they both seemed similar. What interested me is the fact that this was something that I didn’t understand therefore it became a challenge it was the server that I wanted to learn about, the inner working since I loved learning about new things. Now I was very frustrated at first, but in the process of learning I have found and downloaded the operating system on my desktop so that I can learn to be familiar with it. I will give you a little bio as to when I began to show an interest in computer I never had any experiences with server this is my first experience, but with computers that is a different story this is one of the things that I love working with and fixing. When I was a little girl computers fascinated me. At the age of 15 I wanted to know the ins and outs of them. The first computer that I remember it was an Apple or Macintosh that was given to my family. There were little floppy disks that you could use to store things...

...Comparison of Windows, Mac OS X and Linux Operating Systems Team A POS/355 March 6, 2015 Memory Management System Memory management is the process of allocating memory during your programs runtime. Memory Management in MAC OS is a multi-core and multi-processor execution that is supported and a programming API, which is called grand central dispatch. It is in the MAC OS. It provides a pool of available threads. There are ways to prevent memory related problems; Freeing data that is still in use, this can cause memory corruption that can result in your application crashing or worse corrupted user data. The MAC operating system can provide most concurrency as possible based on the number of cores available, and those threads depend on the capacity of the system. Windows memory management system is both physical and has virtual memory. It is mainly controlled by the virtual memory managers and pages. “Windows operating system operates on many platforms then it uses page sizes that can range between 4KB to 64KB. So this means that windows virtual memory can control how memory can allocate paging performance” (Stallings, 2013). Committed, Available, and Reserved are three types of regions of space or memory that the operating system can manage. Committed region is space it’s pages that have been stored either in physical or virtual memory. It also allows the process to access the virtual memory pages. Available region is where the address of the process is not being used...

...Security of Windows NT and UNIX† Hans Hedbom1,2, Stefan Lindskog1,2, Stefan Axelsson1 and Erland Jonsson1 1Dept of Computer Engineering 2Dept of Computer Science Chalmers University of Technology S-412 96 Göteborg, SWEDEN {sax, Erland.Jonsson}@ce.chalmers.se University of Karlstad S-651 88 Karlstad, SWEDEN {Hans.Hedbom, Stefan.Lindskog}@hks.se Abstract This paper presents a brief comparison of two operating systems, Windows NT and UNIX. The comparison covers two different aspects. First, we compare the main security features of the two operating systems and then we make a comparison of a selection of vulnerabilities most of which we know have been used for making real intrusions. We found that Windows NT has slightly more rigorous security features than “standard” UNIX but the two systems display similar vulnerabilities. The conclusion is that there are no significant differences in the “real” level of security between these systems. †Presented at the Third Nordic Workshop on Secure IT Systems, NORDSEC’ 5-6 November, 1998, Trondheim, Norway. 98, 1. Introduction It has been claimed that the security of Windows NT is far better than that of previous commercial operating systems. In order to verify (or refute) this statement we have made a brief comparison of the security of Windows NT to that of UNIX. UNIX was selected as a reference since it is well-known and widely spread. Thus, the target systems were (1) a networked Windows NT 4.0 and (2) UNIX with NFS (Network...

...design capabilities, they create innovative plastic designs that have earned international acclaim. Attention to detail, extreme precision and enthusiastic quality control are the hallmarks of Riordan Manufacturing. With facilities in San Jose, California, Albany, Georgia, Pontiac, Michigan and Hangzhou, China, the company is heavily dependent upon their communication networks. The documentation produced by this analysis will give the management at Riordan Manufacturing an understanding of their networks today, a plan for future upgrades and a baseline to evaluate security. The goal of this exercise is three fold. Our first will be to provide an inventory of the existing network components for Riordan Manufacturing designated by location, review the network security for each site, and our last goal is to document the current security plan for use in future planning. Because of the limited scope of the project, several assumptions must be made. The first assumption is that Riordan Manufacturing has accurate records of the current infrastructure and no changes will be made during this study. Furthermore, we must assume the equipment at each location is similarly configured. The deliverables for this project will consist of an inventory by location of the network in a Visio format, description of the security by location of the network, and recommendations for changes to the network design, circuit speeds, and reasons why the changes should be...

...Security Mac Viruses Many Mac users believe their systems are impervious to threats. This is a naïve falsity of course because no computer system is invulnerable. It is a known fact that Windows can be very prone to virus infections, but since there are so little Mac viruses, people like to get it in their heads that it isn’t possible. Mac OS X is built on the UNIX kernel, one of the most secure operating systems. UNIX creates a file system in which the user isn’t the most powerful role on the computer and needs root permission to really make any major changes. It is technically more secure, but the only other real benefit is that Apple doesn’t populate a large percentage of the PC marketplace. Apple used to encourage this way of thinking, but after the Flashback virus (Perlroth, 2012), they decided it wasn’t a good idea to lie to their customers. Apple replaced their “Why you’ll love a Mac” website containing “It doesn’t get PC viruses” to “It’s built to be safe” (Mlot, 2012). Since malware really only exploits existing bugs or holes in an operating system, it is up to Apple to fix those holes, and they do a pretty good job of it. But in any case, it’s better to be safe than sorry. Some pretty good Mac antivirus include MacKeeper, Kaspersky, and Trend Micro (Sutherland, 2014). Preventative Maintenance With the threats to OS X made real, there are some simple tricks to keep a Mac up and running. The first of which is the ever-important data backup.

...NORTHWEST SAMAR STATE UNIVERSITY Graduate School and Training Academy Calbayog City Course: Master of Science in Information Technology Subject: Client Server Computing Professor: Mr. Donald M. Patimo, MPM Student: Riva A. Gatongay CASE STUDIES IN THIN CLIENT ACCEPTANCE The challenge facing the acceptance of Thin Clients is a combination of architectural design and integration strategy rather than a purely technical issue, and a careful selection of services to be offered over Thin Clients is essential to their acceptance. I. INTRUDUCTION It is generally accepted that in 1993 Tim Negris coined the phrase “Thin Client” in response to Larry Ellison’s request to differentiate the server centric model of Oracle from the desktop centric model prevalent at the time. Since then the technology has evolved from a concept to a reality with the introduction of a variety of hardware devices, network protocols and server centric virtualized environments. The Thin Client model offers users the ability to access centralized resources using full graphical desktops from remotely located, low cost, stateless devices. While there is sufficient literature in support of Thin Clients and their deployment, the strategies employed are not often well documented. To demonstrate the critical importance of how Thin Clients perform in relation to user acceptance this paper presents a series of case studies highlighting key points to be addressed in order to...

...There are some basic safeguards that are important in ensuring that the network infrastructure remains secure for both of the Windows based server and the UNIX/Linux based server. Although both servers utilize the basic level of security, there are vulnerabilities that exist that could be exploited if additional measures are not taken to address them. The following information outlines the steps that are currently in place to address server and other network vulnerabilities. The first step in addressing vulnerabilities that exist within the Windows and UNIX/Linux servers, and the firewall, is making sure that all the latest updates and service patches are installed on all hardware. The Windows based server is utilizing the automatic update feature, and has been configured to allow the download and install all security, reliability, and compatibility updates. The UNIX/Linux based server is also configured to automatically update, downloading and installing updates daily. These updates will enable the servers to obtain the latest patches and updates. This makes sure the firewall will protect our network against the latest viruses, worms, Trojan horses or bugs that would have been created since the last update of the program. Scheduling these services to automatically update our equipment will ensure that the current and newly discovered vulnerabilities are dealt with immediately and considered a must to secure us against these types of problem and intrusions. The next step...

...Mac Memory Management For rough draft Mac OS is available on two processor architectures: the Motorola 68k series and the PowerPC. Mac OS has a flat address space, shared between all processes. There is no per-process memory protection. Application code runs in supervisor mode, so there is no instruction protection. Mac OS has virtual memory, in the limited sense that a larger fixed address space can be simulated, by storing the entire address space on disc. This size of this address space is fixed at boot time. The lowest part of memory is occupied by the system partition. This contains some system global values which applications should not access directly, although there is nothing to prevent them doing so. Historically, the Mac OS used a form of memory management that has fallen out of favor in modern systems. Criticism of this approach was one of the key areas addressed by the change to OS X. The original problem for the engineers of the Macintosh was how to make optimum use of the 128 KB of RAM that the machine was equipped with. Since at that time the machine could only run one application program at a time, and there was no fixed secondary storage, the engineers implemented a simple scheme which worked well with those particular constraints. However, that design choice did not scale well with the development of the machine, creating various difficulties for both programmers and users.
