...Essay 1 What Is There to Worry About? An Introduction to the Computer Security Problem Donald L. Brinkley and Roger R. Schell This essay provides an overview of the vulnerabilities and threats to information security in computer systems. It begins with a historical presentation of past experiences with vulnerabilities in communication security along with present and future computer security experiences. The historical perspective demonstrates that misplaced confidence in the security of a system is worse than having no confidence at all in its security. Next, the essay describes four broad areas of computer misuse: (1) theft of computational resources, (2) disruption of computational services, (3) unauthorized disclosure of information in a computer, and (4) unauthorized modification of information in a computer. Classes of techniques whereby computer misuse results in the unauthorized disclosure and modification of information are then described and examples are provided. These classes are (1) human error, (2) user abuse of authority, (3) direct probing, (4) probing with malicious software, (5) direct penetration, and (6) subversion of security mechanism. The roles of Trojan horses, viruses, worms, bombs, and other kinds of malicious software are described and examples provided. In the past few decades, we have seen the implementation of myriads of computer systems of all sizes and their interconnection over computer networks. These systems handle and are required to protect...

...Operating System Comparisons PRG/355 January 14, 2013 Steven Kernan Operating System Comparisons Table of Contents Introduction 3 Memory Management 3 File Management 4 Security 4 Conclusion 4 Reference 5 Introduction An operating system (OS) is software that manages the hardware and software resources of a computer system. Basically an OS is a set of libraries or functions which programs may use to perform specific tasks relating to interfacing with computer system components (The Computer Technology Documentation Project, n.d.). Advantages and disadvantages exist in every operating system. Reviewed in this paper is a comparison of some of the primary responsibilities of popular operating systems. The review includes Unix/Linux, Mac, and Microsoft Windows operating systems. Memory Management An important function of the OS is to manage the computer systems memory. Programs, processes, and resource do not simply float around in memory haphazardly. Memory is shared among these processes and resources. Accordingly, managed by the OS is an organized structure of locating processes in computer memory locations. The two primary types of memory controlled by an OS are main memory and virtual memory. Main memory is… (need general definition). Virtual (secondary) memory is… (need general definition). Intended memory management requirements include relocation, protection, sharing, logical organization, and physical organization. Processes may...

Along with I will discuss two cases of such fraud in UAE and finally I will discuss possible precautions to mitigate the risk of such frauds. In recent year the computer network threats become technically more advanced, sophisticated, more organised and at the same time difficult to detect. It is important to mention that these attacks not only damage network security for financial frauds but this also aim to disable and reliability of the infrastructure as well, which may cause worse type of threat to the national security. (Tom Cross and Eric Savitz, Forbes Staff, 2012) Threats Most respected financial magazine FORBES has mentioned five main security threats to the computer networks which includes. • State-sponsored espionage and sabotage of computer networks o In 2012 a very famous virus called Flame was discovered which was not traced by the software in years. Similarly virus named Shamon destroyed the data of oil and energy companies and made the machines unbootable. • Monster DDoS attacks o DDos stands for the...

Introduction: Today , the world is moving towards a point where everything from banking, stock exchanges, traffic control, telephones to electric power, health care, welfare and education depends on software. Undoubtedly, this advancement and globalization offers many benefits to consumers and businesses but, unfortunately it also offers plenty of opportunities to organized crime. Globalization has promoted and strengthened the economics of illegal activities; offenders have become international entrepreneurs. The Internet provides money and information to all sorts of customers and businesses. It is notably the home of virtual worlds and their economies, which have attracted many people, including criminals. The unholy marriage of the Internet and crime has created a new form of crime -“CYBERCRIME” What is Cyber Crime? Cyber Crime is an unlawful act commited using a computer (and/or internet)...

...Introduction the world today and the ballistic use of information systems networks has made several countries progressively interconnected and mostly in technologically advanced countries, computer network perform a key role in how companies carry out business, how services are provided by government to its citizens and how different individual communicate and trade important information (Downing, 2005). this exchange of information through the use of computer/internet brings about what is known as cybercrime Speer (2005) defines cybercrime as activities in which computers, telephones and other technological devices are used for illegal objectives such as theft, fraud, electronic defacement and breach into computer system and networks. however, security managers need to have a full knowledge of cybercrime because it is the rising mode of crime and the least reported (Phair, 2007). Security managers and cybercrime security managers need to understand that cybercrime has become a profanity in the society which affects everyone both nationally and internationally, individuals, institution, companies as well as the government and this is however a rumination of the growth of criminals practices (Helle et al, 2012). there are various characteristics of cybercrime that need to be understood by security managers and they include: it is usually a distinct/singular event from the victim's perspective, it is often facilitated by crime-ware program introduction and its introduction...

...Security Introduction Security introduction is what the first video is about; it tells us what topics the next seven videos will cover. * Local Security Policy * Physical Security * Firewall * Wireless Security * Authentication * Encryption * Viruses Physical Security & Authentication In this video we learn about how to secure your computer and servers theft or tampering. You would do this by locking and controlling access to servers and locking computer cases as well. To protect them even further you should put server locations in high traffic areas, and create administrative alerts with audible alarms. You should also store backup in a separate and secure location, and lock user operating systems. Always physically destroy hard drives. This video also teaches us about CMOS password and how to set them up. We can create limits to the access through CMOS with full, limited, view only, and no access. We also learn about password protecting the hard drive. * Physical Security * Authentication * CMOS Password * Kerberos-Method used to encrypt passwords What I learned from this video is that companies go through great lengths to protect their computers and servers from intrusion. This video was basic and straight forward and not confusing at all, if anything its confusing that we should have to do so much to secure our files. I guess this information would best be used if you working for security...

...Privacy and Security Table of Contents Introduction 3 Why Protection 4 Computer Virus 4 How Viruses Infect Computer 5 How People Hack Computer Systems 6 How to Keep Computers Safe from Online Predators 7 Conclusion 10 REFERENCES 11 Introduction The role of computer systems is very vital in our daily lives. Since computers help us to deal with approximately all the major functions of our lives as well as are so inevitable that spending even a day or two away from the computer can leave us feeling powerless. In this prospect, many people control their routine lives by means of their personal computers. However, at the present computer security has become a very critical issue. Additionally, security refers to the technique to discover as well as stop illicit utilization of our secret information or computer. In this scenario, some preventive measures enable us to stop criminal users (as well known as "intruders") from accessing and using some part of our computer system. In addition, recognition of such intrusions helps us in deciding whether or not somebody tried to gain access into our computer system, if they were successful in their attempt, as well as what they could have acquired from the system (ComputerSecurityService, 2011), (Armor2net Software Ltd., 2004) and (Norton, 2001). In addition, the term “computer security” is very commonly used, though; the information and data saved on a computer are in danger...

I am writing on these two due to the fact that these are two job considerations for my degree. I will be discussing benefits of each job, average pay, and description of each job. I will take time to go into detail into each of the jobs that I would like to have. I will be going into the origin of each job, degrees required for each job, and the different fields that these jobs cover. Purpose The purpose of this report is to educate others and myself on what these two jobs are about. To better inform others of the importance of each of these jobs in the digital world. It will hopefully allow others to have a better understanding of the two jobs that I have chosen. There are many things about each of these jobs that people would deem as boring or not interesting, but the digital world is a very interesting place. It is like another world laid on top of this one, there but just out of reach unless you have the technology to access it. There are many things one can gleam from the internet and the digital world, and I will expound upon...
