...Computer security and Network Security is the means by which business and governments are protecting against computer intrusions and attack to prevent loss of data, information and provided services. Everything is now on computers, peoples whole lives are documented on computers. Big business and the government rely on technologies that use computers, whether it is used for storage, a medium between the customers and themselves or actual work. With all this information and data being stored, transferred and used it needs to be secured. A bank is open to the public; you would not have this bank unsecured would you? There would be security guards, cameras, and a vault. The same mentality to secure your data should be implied if you have a network that is connected to the Internet. You should have software, hardware, and/or personnel monitoring your networks operations and security. All computers and systems that connect to the internet or networks run off software of some type. People called hackers or crackers, manipulate programs, create worms, and viruses to make systems do thing there not supposed to, access places they aren’t allowed, and shutdown or hinder a system from working properly (Dasgupta). Then there are attacks, phishing attacks which come in the form of email that try to lead you to fraudulent sites, Denial-of-service attacks overload servers causing no one to get on or shuts them down. Then there are SQL injection attacks which are used in security vulnerable...

...Social Science Research Within the disciplines of sociological and cultural anthropology, research methods have similarities and differences based on philosophical roots that determine how a researcher will interact with study subjects to produce data or aesthetic judgments for an holistic understanding of individual or societal behavior. To what degree researchers will interact with participants is determined in two approaches that either promotes positivism or constructivist viewpoints. Positivism, according to Williamson (2006), considered as the investigation of human and social phenomena by observable and measureable methods, produces quantitative and reproducible data. In the viewpoint of positivism, data is obtained from the contextual origin and knowledge is determined as an external reality, one that is not integrated with the contextual milieu or qualitative variances (Williamson, 2006). According to Nomalungelo (2012), the positivist viewpoint is aligned with traditional western-based science, limiting in its integration of research with other qualitative approaches, paradigms and world views. Conversely, constructivism, as described by Nomalungelo (2012), is knowledge produced from intersection of human interaction and social processes, resulting in dynamic development of qualitative knowledge as the viewer creates varying interpretations from a continuously shifting, contextual social reality. Therefore, the discovery of new meanings and realities are reached...

...Assignment 9. Research Paper Introduction to IPv4 & IPv6 IPv4 is the fourth version of Internet protocol which uses 32 bit addressing whereas IPv6 is a next generation internet protocol which uses 128 bits addressing. 32 bits long (4 bytes). IPv4 is a classful logical addressing scheme using three primary address classes: Class A, Class B, and Class C. The class of the address is determined by the first number in the IP address. The total number of IPv4 addresses is 4, 294, 967,296. Address type: Unicast, multicast, and broadcast. IPv4 expressed in dotted decimal notation. The new concepts and new implementation of old concepts in IPv6 include the following: * Larger address space (128-bit vs. 32-bit) * Autoconfiguration of Internet-accessible addresses with or without DHCP (without DHCP it’s called stateless autoconfiguration) * More efficient IP header (fewer fields and no checksum) IPv4 allows 4,294,967,296 unique addresses whereas IPv6 can hold 340-undecillion (34, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000) unique IP addresses. 128 bits long (16 bytes). Basic architecture is 64 bits for the network number and 64 bits for the host number. Often, the host portion of an IPv6 address (or part of it) will be a MAC address or other interface identifier. Address type: Unicast, multicast, and broadcast and anycast. IPv6 expressed in colon hexadecimal notation. DHCP servers in Linux can be configured to use IPv6: * Step 1: configure...

...Life Span Development and Personality xxxxxxxxx PSY 300 – General Psychology xxxxxxxxxx xxxxxxxxxxxxxx Life Span Development and Personality “Oprah Gail Winfrey is an American media proprietor, talk show host, actress, producer, and philanthropist. Winfrey is best known for her multi-award-winning talk show The Oprah Winfrey Show, which was the highest-rated program of its kind in history and was nationally syndicated. She is also, according to some assessments, the most influential woman in the world.” (Henry, 2007). In this paper we will discuss at length about her personality, her heredity vs. her environment, and how they have played a crucial role in Oprah Winfrey’s life and psychological development. So who is Oprah Winfrey? Oprah Gail Winfrey was born on January 29th, 1954 where she was born to a single mother living below the poverty line in rural Mississippi (Novit, 1986). Oprah’s mother wanted more for her daughter than she had for herself, however wasn’t able to provide for her. Shortly after Oprah’s birth she was sent to live with her grandmother in the inner city of Milwaukee (Alchin, 2008). Oprah’s grandmother was so poor it is said that “she made Oprah ware dresses made from potato sacks” (Novit, 1986). Oprah’s grandmother taught her to read and write by the age of three, making her read and write bible verses over and over again (Novit, 1986). Oprah’s grandmother took her to church every week showing off her beautiful granddaughter’s talents...

...GLOBAL ACCOUNT MANAGEMENT Introduction Due to globalization of economics, advances in communication and information technologies, rapid changes in global market and consumers and availability of a transnational media, makes the world an enormous borderless marketplace. Accordingly many of multinational companies have adopted global account management as a substantial strategic account and integral part of global marketing, and have focused on global consumers’ important demands. Global vs. Nation Account Management Global account management (GAM) emerged as a plan or process of relationship focusing on future of global client’s major demands, and understands them towards to increasing the return on company’s and stakeholders’ investments. Then companies must gain proper perceive of their customer’s demands, and tailoring their approach according to their customer’s needs (Woodburn & McDonald, 2011, pp.5-7). Nation or domestic account management implies on delivering service or serving the demands of consumers that are located in a nation or region; on the other hand, global account management is refer to delivering services or serves the customer’s demand throughout the world. Accordingly multinational companies needs to adopt larger accounts based on their multiple locations around the world while domestic or nations companies doesn’t needs to (Honeycutt et al, 2003, p.102). Then it is obvious that GAM’ faces larger and more sophisticated challenges, and in compare...

...A Five-Year Study of File-System Metadata Nitin Agrawal University of Wisconsin, Madison nitina@cs.wisc.edu William J. Bolosky, John R. Douceur, Jacob R. Lorch Microsoft Research {bolosky,johndo,lorch}@microsoft.com Abstract For five years, we collected annual snapshots of filesystem metadata from over 60,000 Windows PC file systems in a large corporation. In this paper, we use these snapshots to study temporal changes in file size, file age, file-type frequency, directory size, namespace structure, file-system population, storage capacity and consumption, and degree of file modification. We present a generative model that explains the namespace structure and the distribution of directory sizes. We find significant temporal trends relating to the popularity of certain file types, the origin of file content, the way the namespace is used, and the degree of variation among file systems, as well as more pedestrian changes in sizes and capacities. We give examples of consequent lessons for designers of file systems and related software. characteristics of file systems, including file and directory population, storage capacity, storage consumption, and degree of file modification. The contributions of this work are threefold. First, we contribute the collected data set, which we will sanitize and make available for general use later this year. This is the largest set of file-system metadata ever collected, and it spans the longest time period of any sizeable metadata collection. To obtain this...

...Constitutional Rights Constitutional Rights and Challenges for Freedom of Information and Speech Folorunso Eddo PAD 525 Constitutions and Administrative Law Professor Richard Freeman May 20, 2012 ABSRACT The First Amendment stated that all American citizens are entitled to the freedom of speech and association. However, the Supreme Court has ruled many times that that right is not completely guarantied. In the work place there are laws that protect us from workplace harassment. There is thin line between freedom of speech and sexual or other forms of harassment. The Freedom of Information Act empowered private citizens and organization to ability to request information from any government agency but sometime there may be a conflict in what the agency would want to allow for the public due to the national security. It is times like this that the Supreme Court is required to be involved. On February 1986, Lawrence Korb the vice president of Washington operation for Raytheon was invited to speak at a Washington policy group on Capitol Hill in Washington D.C. Before then, He was assistant secretary for defense in the Reagan’s administration. In his speech Korb advocated the need for the Reagan Administration to reduce its budget spending in line with the budget and reduce the budget deficit. In his speech, he listed some of the agencies that he believed that could be reduced and what programs. The next morning...

...The Design Space of Metamorphic Malware Andrew Walenstein†, Rachit Mathur‡, Mohamed R. Chouchane†, and Arun Lakhotia† University of Louisiana at Lafayette, Lafayette, LA, U.S.A. McAfee Avert Labs, Beaverton, OR, U.S.A. arun@louisiana.edu rachit_mathur@avertlabs.com mohamed@louisiana.edu walenste@ieee.org ‡ † Abstract: A design space is presented for metamorphic malware. Metamorphic malware is the class of malicious self-replicating programs that are able to transform their own code when replicating. The raison d'etre for metamorphism is to evade recognition by malware scanners; the transformations are meant to defeat analysis and decrease the number of constant patterns that may be used for recognition. Unlike prior treatments, the design space is organized according to the malware author's goals, options, and implications of design choice. The advantage of this design space structure is that it highlights forces acting on the malware author, which should help predict future developments in metamorphic engines and thus enable a proactive defence response from the community. In addition, the analysis provides effective nomenclature for classifying and comparing malware and scanners. Keywords: Metamorphic Malware, Virus Scanner. 1. Introduction Metamorphism is the ability of malware to transform its code. This ability was first introduced in viruses and was later used by worms, Trojans, and other malware. There now exist several metamorphic engines—programs that implement...

...Introduction This paper explores three philosophical issues. The concepts examined are personal identity, virtue ethics, and ethical relativism. A personal philosophy in relation to each concept is identified and described. In conclusion, philosophical findings are incorporated into a personal view on the ultimate meaning of life. Philosophical Issues Personal Identity Personal identity of the most basic nature is “what makes one the person one is” (Olson, 2010). This basic nature then leads to the complexities of personal identity. Complexities include questions such as: * Who am I? * What is it to be a person? * What does it take for a person to persist from one time to another – that is, for the same person to exist at different times? * How do we find out who is who? * What am I? * How could I have been? * How different could I have been from the way I actually am? (2010) These questions are crucial to discovering self-purpose of life. Hume’s philosophy is that personal identity is “nothing but a bundle or collection of different perceptions” and “too inconstant” (n.d.). Several philosophers disagree, arguing that “when the soul and the body are united, then nature orders the soul to rule and govern, and the body to obey and serve” (Chaffee, 2011, p. 91). There are many theories of philosophy pertaining to personal identity and social identity. In most cases, the compulsion to rationalize identity by understanding and knowing who...

...A Tale of Two Processors: Revisiting the RISC-CISC Debate Ciji Isen1, Lizy John1, and Eugene John2 1 ECE Department, The University of Texas at Austin ECE Department, The University of Texas at San Antonio {isen,ljohn}@ece.utexas.edu, ejohn@utsa.edu 2 Abstract. The contentious debates between RISC and CISC have died down, and a CISC ISA, the x86 continues to be popular. Nowadays, processors with CISC-ISAs translate the CISC instructions into RISC style micro-operations (eg: uops of Intel and ROPS of AMD). The use of the uops (or ROPS) allows the use of RISC-style execution cores, and use of various micro-architectural techniques that can be easily implemented in RISC cores. This can easily allow CISC processors to approach RISC performance. However, CISC ISAs do have the additional burden of translating instructions to micro-operations. In a 1991 study between VAX and MIPS, Bhandarkar and Clark showed that after canceling out the code size advantage of CISC and the CPI advantage of RISC, the MIPS processor had an average 2.7x advantage over the studied CISC processor (VAX). A 1997 study on Alpha 21064 and the Intel Pentium Pro still showed 5% to 200% advantage for RISC for various SPEC CPU95 programs. A decade later and after introduction of interesting techniques such as fusion of micro-operations in the x86, we set off to compare a recent RISC and a recent CISC processor, the IBM POWER5+ and the Intel Woodcrest. We find that the SPEC CPU2006 programs are divided between...

...The Challenges and Effective Methods of Investigating Juvenile Offenders and Delinquents CRJ 105 August 24, 2014 The Challenges and Effective Methods of Investigating Juvenile Offenders and Delinquents Criminal behavior in juvenile offenders has plagued justice from the beginning. Hagans book Introduction to Criminology discusses the relationship between age and crime in detail. I’ve always been interested in the real effects of a juvenile arrest record and how it will follow them for life. The book also states that “arrest data shows that the intensity of criminal behavior slackens after the teens”. So how are these young adults treated and tracked through the system? There have been many important movements and legislation though history towards the shaping and treatment of juvenile offenders and delinquents. The Juvenile Justice System today is by no means perfect, but it is far greater than what was initially in place. During these times, anyone under the age of seventeen who committed a crime was placed in the same judicial system as adults. As social views began to change, many started to see juvenile offenders as youths who had simply lost their way, rather than hardened criminals. The first large movement involved with removing juveniles from the adults took place with the Houses of refuge. In the early 1800’s reformers became concerned about the overcrowded conditions in the jails and the corruption youth experienced when confined with adult felons. The...
