...the 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...

...Unix/Windows Systems Review for Riordan Manufacturing Micah Gerber POS/420 December 21, 2012 Charles Mathieu Abstract Riordan Manufacturing is the leader in the plastic injection molding industry with facilities in both the United States and China. As a large global operation, having adequate systems in place to support the organization network and databases is of upmost importance. A critique which addresses the benefits and disadvantages of using UNIX or Linux versus Microsoft Windows Server within Riordan Manufacturing will be completed by Team A. Areas to be addressed within the critique will cover security, administration, networking, performance, programmability, and reliability as it relates to UNIX or Linux and Microsoft Windows Server. Riordan Manufacturing currently has a combination of Unix and Windows servers which support the organization, however, the team will recommend that the organization standardize it’s systems to support one platform across the agency. Through this recommendation Riordan’s Manufacturing infrastructure will have one platform Security Review The histories of both Windows and UNIX security development have taken diametric paths. The Windows operating system (OS) is monolithic by design, which means that most of the features are integrated into a single unit and is located into the core of the OS. UNIX, on the other hand is based on the core of the operating systems residing in a distributed manner where...

...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...

...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...

...Differences and Similarities Between Operating Systems POS/355 Intro to Operating Systems November 5, 2012 Differences and Similarities Between Operating Systems There are many similarities and differences among the top desktop operating systems UNIX/Linux, Windows, and Mac. An operating system is the software which operates the basic functions of a computer. Among these functions are task scheduling, I/O, and the execution of programs. There are key areas in which these operating systems must function. Memory management, processor management, file management, and security are the main focus of an operating system. Memory management refers to the way an operating system manages the computer memory. Processor management is the way the computer handles processing of programs. File management is the way an operating system allows files to be saved, deleted and handled by the user. Security is addressed by the operating system to ensure that the files on a computer are safe from unwanted intrusion and manipulation. Each of the three operating systems confronts these functions in their own way. In some ways they are similar and there are also specific differences. Memory management is the function of a computers operating system responsible for managing the computers primary memory. The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding who gets...

...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...

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 needed must be accessible in the Main Memory at the demand of the CPU. When a page is expected to be needed in the very near future it is called a resident set. This can lead to errors due to memory allocation issues. If the CPU attempts to access a page that...

...Securing Windows and Unix/Linux Servers Floyd E. Street DeVry University Securing Windows and Unix/Linux Servers With the constant threat of internet hackers on the rise, Companies must pay close attention to secure their computer networks from would be intruders. In order to maintain the highest level of security within the os servers you must first have knowledge of the vulnerabilities of the running operating system. It is those vulnerabilities in the system that the intruders will be searching your network for. The known shortcomings and vulnerabilities of Windows and Unix/Linux servers have dysfunctions that can be exploited to gain access to a company’s private information. This information in the wrong hands could cost an organization millions of dollars in security damages. One of the ways to prevent this type security breech is to make sure that your Windows and Unix/Linux servers has the right up dated patches for these operating systems. According to, (Conklin, W. A.2009) “One of the most effective measures security professionals can take to address attacks on their computer systems and networks is to ensure that all software is up-to-date in terms of vendor-released patches. Many of the outbreaks of viruses and worms would have been much less severe if everybody had applied security updates and patches when they were released.” Ignoring the update prompts on your system is not a wise thing to do. New vulnerabilities in operating...
