...UNIX, Linux, and Windows Servers Security When comparing Linux/Unix versus Windows platforms for security it is important to take into account the security issues being addressed. The most common types of security breaches in today’s business world are based on social engineering attacks. These attacks are focused on bypassing security measures by tricking users into accomplishing the tasks required by the malicious code. These attacks can introduce numerous types of malicious code into the network ranging from spyware up to and including viruses. When comparing Windows versus Linux/Unix it is important to realize that more security features may be available depending on the exact operating system. This comparison is not to compare specific distributions of Linux/Unix against a specific version of Windows, instead it will compare the core elements that are prevalent in both operating systems regardless of the distribution or version chosen. The first security feature that is discussed is the structure of both operating systems. The difference between Linux/Unix and Windows based on structure is the way configuration for software is approached. Most malicious code in a Windows platform is embedded into the registry. The registry is a single location that stores every configuration setting for software installed on the machine. This allows a standard location for malicious code to target on a windows machine. Whereas Linux/Unix does not have a registry, instead it uses...

...UNIX®/Linux® versus Mac® versus Windows® POS/355 October 29, 2012 Carol S. Eichling UNIX®/Linux® versus Mac® versus Windows® There are several computer operating systems available on the market, and it is sometimes difficult to choose. Therefore, it is important to compare the system capabilities to make the decision easier. The three biggest players in the operating systems market are UNIX®/Linux®, Mac®, and Microsoft® Windows® with Windows® holding the largest market share (Boitor & Brătucu, 2011). These three operating systems are capable of multi-processing and have similar capabilities; however, and it is important to compare and contrast how they handle memory management, process management, file management, and security, which are critical system functions. Discussing memory management, which is a vital component in operating systems, is first. Memory Management Memory management refers to the way a system makes use of the computer’s RAM (Random Access Memory). Many of the operating systems in use on computer systems have positives and negatives in their use of memory attributes. “Memory management is usually divided into three areas: hardware, operating system, and application…although the distinctions are a little fuzzy. In most computer systems, all three are present to some extent, forming layers between the user's program and the actual memory hardware” (Ravenbrook Limited, 2001, p. 1). There are several types of memory, including main memory, file system...

...Premise Linux was created as a variation of UNIX by Linux Torvalds in 1991. He created it as open source with a GNU (GPL) General Public License and a lot of coders began downloading the source code and creating their own programs with it. They created patches and fixes for bugs to improve the Linux OS use experience. Security Advantages and Disadvantages Linux and Windows Server share logical security mechanisms that work similar in principle. Both are advantages in their own right using different techniques to secure a network. The importance of network security and how users have access to a network can be maintained not only through best practices but, a strict policy as well. Linux and Windows Server use security mechanisms directly manipulated by the OS, called account privileges. The key advantage with this mechanism is how it assigns a user account privilege to folders and files within the operating system. Linux users are not assigned “root “privilege as default instead the user is assigned an account with low-level privilege. Setting read, write, and execute permissions for owner, group, and other users to give them access control to specific files and folders is usually controlled through the Command Line Interface (CLI) yet some distributions of Linux may also have a Graphical User Interface (GUI) that allows an administrator to change permissions. Windows Server is similar in the way is too assigns account privileges to users. The client/server architecture...

...Introduction of Operating Systems In today’s technological world there are so many different, new and exciting advances happening every day. But many of us are confused, when it comes to the basic understanding of this new technology. The area people need to start when trying to understand the basics of any computer hardware system would the operating system. Operating systems are a program which manages the computer’s hardware. These systems provide a basis for application programs and intermediate between the computer’s user and its hardware. There are many different types of Operating serves that are available to use. There are four main Operating systems that are used in today’s Technological world: UNIX, Linux, Mac, and Windows. Each one of these systems has its own unique aspects to offer users, while still sharing the same basics that an operating system needs. Memory Management UNIX/Linux In comparison to other operating systems, UNIX is quite different when it comes to managing its memory. It uses extremely sophisticated memory management algorithms to make the best use of memory resources. Though UNIX and Linux are extremely similar when it comes to how things work internally, there are slight differences that make UNIX distinct. One process that UNIX uses is Swapping; this is done by moving chunks of the Virtual Memory, known as pages, out of the main memory and moving others in. In order for this process to work at its best, those pages that are...

...by Elsevier B.V. Linux vs. Windows: A Comparison of Application and Platform Innovation Incentives for Open Source and Proprietary Software Platforms Nicholas Economides and Evangelos Katsamakas ABSTRACT The chapter analyzes and compares the investment incentives of platform and application developers for Linux and Windows. We find that the level of investment in applications is larger when the operating system is open source rather than proprietary. The comparison of the levels of investment in the operating systems depends, among others, on reputation effects and the number of developers. The chapter also develops a short case study comparing Windows and Linux and identifies new directions for open source software research. Keywords: Open Source Software, operating systems, technology platforms, Linux, innovation incentives. JEL Classification: L 10, L86, L3 1. 10.1 INTRODUCTION Open source software is an emerging type of software that may fundamentally affect the business and economic features of the software industry. Linux, an open source operating system, has been the prominent example of the potential of the open source movement, competing against Microsoft Windows, the incumbent operating system. 208 Nicholas Economides and Evangelos Katsamkas This chapter analyzes the incentives to invest in application software and an operating system under two different software ecosystems: one based on an open source operating system, such as Linux, and the other...

...Linux Linux What is an ‘Operating System’? Mac OS Mac OS An operating system is the program that acts like the brain of the computer. It is used to control everything. The operating system controls programs and the functions of the computer along with the hardware, software' and file organisation. Computers need an operating system so that they can complete tasks. All programs, software’s and hardware’s need something to tell them how to perform their task, and this is what the operating system is used for. Without one, your computer would be useless. Operating systems are designed to make the computer more convenient for the user; it displays all of the information for the user in a clearer layout. Some popular operating systems are Windows 8.1, Mac OS and Linux. There are 2 variants of operating systems; A Command Line Interface (CLI) and a Graphical User Interface (GUI). Windows 8.1 Windows 8.1 Command Program Command Program Command Line Interface: A ‘Command Line Interface’ is a variant of operating system that allows the user to directly interact with the computer by typing in commands. The computer displays a command program or command box that allows the user to give the computer instructions by entering the command and pressing the enter key. CLI is used by mostly professional programmers who have experience in computer languages. Using CLI doesn’t restrict you as GUI does. It allows you to look into program files and rewrite how the program works. Although...

...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...

...PT2520: Database Concepts Week 4 Essay: Comparing DBMS Comparing DBMS What is database management system (DBMS)? Database management system is reliable mean to organize date into a single location that can be searched and updated at any time. By adding all the information in one location or in this case a server you are storing the information for later use. You can than search any information you require and update it or even remove old items from the database. Today there are several different options or providers for a DBMS server. Among the top providers you have Oracle, MySQL, IBM DB, MS SQL Server. Oracle 12C Oracle 12C is a cloud base database management system. It supports the following operating systems (OS) Microsoft Windows, Linux, Oracle Solaris and some Unix. It is a web-based interface that stores all the procedures on the Oracle Management Repository. The most recent update was released on September 30, 2014. Some of the benefits of Oracle 12c are the following. Per oracle documentation “It provided a secure multitenant application by adding a layer of abstraction or containerization. It allows you to use the cloud providers for an easy and quick mean to allocate and manage the database across multiple systems and data centers without changing the application”. It also provides a disaster recovery, backup, patching, cloning and upgrading flexibility. Oracle is able to replace or move any information while you use either of the following RMAN, Data Guard...
