...Project Student College Case Project Linux as an operating system is a powerful tool used in businesses for its secure kernel and command line interface. From a small business to a large enterprise, Linux is used to run servers, store vital information and documents. In Outdoor Adventures, this store needs a more efficient computing system. The system will need to keep information available and secure enough to ensure that the information can only be seen by the right people. To help keep things organized, a file structure will also be required to keep all the files with special permissions together for easy access. To better illustrate the security capabilities of Linux Ed Sawicki of Biznix.org said, “The Linux firewall has functionality that rivals expensive commercial firewalls. Its rules allow fine grained control over stateless and stateful packet filtering. The Linux firewall is extensible, allowing new filtering capabilities as the need arises.” This comparison is powerful when considering what would be the most cost effective direction for a business, but also the safest. Another advantage of linux is that it is generally free to try before applying it to a commercial setting. The product can in effect speak for its self by allowing itself to be made publicly available so there is no need to consider it a “business risk” when a technician can experiment with it first before applying it on a much grander scale. “Linux…is a freely available multitasking and multiuser...

RED HAT ENTERPRISE LINUX Costs of Acquisition and Support – A Comparison August 2005 PREPARED FOR Microsoft TABLE OF CONTENTS Main Findings.................................................... 1 Executive Summary ......................................... 2 Analysis ............................................................. 2 License and Subscription Considerations Support Considerations The Total Solution Viewpoint 2 3 6 Main Findings 1. Microsoft’s Windows Server 2003 enterprise license and support costs are competitive with Red Hat Enterprise Linux. 2. The two companies’ different approaches to enterprise licensing and support, and the fact that investments of this magnitude tend to involve longer-term commitments, means that the best pricing comparisons should be based on a period of ownership (three to six years), rather than on just initial acquisition charges. 3. Support is integral to both companies’ solutions and Microsoft’s separate support and license fee structures, in contrast with Red Hat's combined subscription and support offerings, can give a Microsoft solution a significant pricing advantage over a Red Hat solution.

Performance 10. Market adoption 11. Education 12. Future of desktop linux 13. Conclusion Introduction “Bill Gates was the first to realize the power of ‘good enough.’ We don’t have to offer the perfect desktop environment, just one that’s good enough for most people.” [pic] Desktop Linux, also called Linux on the desktop, refers to specialized Linux distributions with features designed for desktop personal computer users. These features include a graphical user interface and personal use applications. Some Linux distributions have targeted the desktop role specifically, while others include all the software available for the platform. In that case, the user will be given the choice to select either a "desktop" or "server" type when the operating system is installed. THE ADOPTION CYCLE Looking back Many technologies have enjoyed widespread success when a new application was released that allowed the benefits of the new technology to fully demonstrate themselves. The Macintosh computer, for instance, started gaining momentum with the release of Adobe Pagemaker and the postscript printer, creating the desktop publishing industry. Likewise, the Internet was used only in academic and technical circles...

...Electrical & Computer Sciences IJECS-IJENS Vol:12 No:04 25 Studying Main Differences Between Linux & Windows Operating Systems Lecturer/ Hadeel Tariq Al-Rayes Abstract—Comparisons between the Microsoft Windows and Linux computer operating systems are a long-running discussion topic within the personal computer industry. Throughout the entire period of the Windows 9x systems through the introduction of Windows 7, Windows has retained an extremely large retail sales majority among operating systems for personal desktop use, while Linux has sustained its status as the most prominent Free Software and Open Source operating system. After their initial clash, both operating systems moved beyond the user base of the personal computer market and share a rivalry on a variety of other devices, with offerings for the server and embedded systems markets, and mobile internet access. Linux and Microsoft Windows differ in philosophy, cost, versatility and stability, with each seeking to improve in their perceived weaker areas. Comparisons of the two operating systems tend to reflect their origins, historic user bases and distribution models. Index Term— Kernel, Linux, Operating Systems, Windows II. THE ESSENTIAL DIFFERENCES BETWEEN LINUX & WINDOWS (BEGINNERS LEVEL) 1- Drives don’t have letters, they have mountpoints The first thing that usually trips up people who come from Windows to Linux is that filesystems aren’t assigned letters the way they are in Windows. Instead, there is...

...Unit 4 Discussion 1: Compromising an Online System Learning Objectives and Outcomes * You will be able to explore how a Linux system can get compromised. * You will examine ways in which a well-secured Linux filesystem can mitigate risks. Assignment Requirements The Apache Software Foundation (ASF) is a reputable open source foundation that has a history of developing and maintaining many open source products, including the Apache Web Server. In April 2010, the ASF discovered that their server hosting issue-tracking software was “hacked.” You can read a report on the incident on the following Web link: * https://blogs.apache.org/infra/entry/apache_org_04_09_2010 This report documents how a vulnerability was exploited, which solutions worked, which didn't work, and the measures planned by the Apache Infrastructure Team to mitigate future risks. Security is a layered process. Although the hackers took advantage of a vulnerable third-party Web application to gain root access to ASF’s Linux infrastructure, you need to focus on the layers of security that worked and failed on the Linux infrastructure, and how this vulnerability could have been avoided with a more secure Linux server. Discuss how the hackers took advantage of the JIRA daemon. What role did Pluggable Authentication Modules (PAM) play in this process? What are the security measures that you would recommend to mitigate such risks in the future? Participate in this discussion by engaging in a meaningful...

...POS/335 03/06/2013 Mr. STERNIERI Closed Source Vs Open Source In the world of operating system we have two options to choose from these is Unix/Linux which is an open source, meaning that its source code made available and licensed with an open source license in which the copyright holder provides the rights to study change and distribute the software to anyone and for any purpose. The other option is the closed source such as Microsoft’s Window which is software released or distributed without the corresponding source code. Generally, it means only the binaries of a computer program are distributed and the license provides no access to the program's source code. The source code of such programs might be regarded as a trade secret of the company. Access to source code by third parties commonly requires the party to sign a non-disclosure agreement. I also will like to discuss what source codes are and why having the right combination will give us free bees. What some of the major differences between an open source and a closed source? I see it all over the internet the heated debate of which is better open source or closed source and even though both sides have good supporting evidence to back up their claim about every from which is more secured to who has the better functional software. The argument of Windows vs. Linux is a greatly debated one, and in recent years has become quite heated. Because Microsoft's attempt to recover from its bruises from Windows Vista. Microsoft...
