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...

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...

...1. What are other available Password Policy options that could be enforced to improve security? Enforce password history, Maximum password age, Minimum password age, Minimum password length, Password must meet complexity requirements, & Store passwords using reversible encryption. 2. Is using the option to ‘Store passwords using reversible encryption’ a good security practice? Why or why not? As it stores passwords without encrypting them, it is not good practice because they will be stored in plain text. 3. When should you enable the option to ‘Store passwords using reversible encryption’? Only when using a program that requires it. 4. Why should you use the different password policy options available (with exception to storing the password using reversible encryption)? Enforce password history - Prevents users from creating a new password that is the same as their current password or a recently used password, Maximum password age - Sets the maximum number of days that a password is valid and after this number of days, the user will have to change the password Minimum password age - Sets the minimum number of days that must pass before a password can be changed Minimum password length - Specifies the fewest number of characters a password can have Password must meet complexity requirements - Requires that passwords: be at least six characters long/contain a combination of at least three of the following characters: uppercase letters, lowercase...

...Questions 1. What is the difference between a threat agent and a threat? A threat agent is a specific component that represents a danger to an organization’s assets. And a threat is an object, person or entity that represents a constant danger. 2. What is the difference between vulnerability and exposure? Vulnerability is a weakness is a system that leaves the system open to attacks. Exposure is the known vulnerabilities that make a system weak and open to attacks without protection. 3. How is infrastructure protection (assuring the security of utility services) related to information security? If the infrastructure of a network is exposed and accessible to anyone this leaves the network vulnerable to damage both to hardware and software. The infrastructure must be protected to allow only authorized user to have access to the network. 4. What type of security was dominant in the early years of computing? Physical security. 5. What are the three components of the C.I.A. triangle? What are they used for? Confidentiality, Integrity and availability are the three components of the C.I.A triangle. They are used as a standard for computer security. 6. If the C.I.A. triangle is incomplete, why is it so commonly used in security? The C.I.A triangle provides a basic standard of what is needed to keep information secured. 7. Describe the critical characteristics of information.

...Principles of Information Security, 4th Edition 1 Chapter 1 1 Review Questions 1. What is the difference between a threat agent and a threat? A threat agent is the facilitator of an attack, whereas a threat is a category of objects, persons, or other entities that represents a potential danger to an asset. Threats are always present. Some threats manifest themselves in accidental occurrences and others are purposeful. Fire is a threat; however, a fire that has begun in a building is an attack. If an arsonist set the fire then the arsonist is the threat agent. If an accidental electrical short started the fire, the short is the threat agent. 2. What is the difference between vulnerability and exposure? Vulnerability is a weaknesses or fault in a system or protection mechanism that opens it to attack or damage. Exposure is a condition or state of being exposed. In information security, exposure exists when a vulnerability known to an attacker is present. 3. How is infrastructure protection (assuring the security of utility services) related to information security? The availability of information assets is dependent on having information systems that are reliable and that remain highly available. 4. What type of security was dominant in the early years of computing? In the early years of computing when security was addressed at all, it dealt only with the physical security of the computers themselves and not the data or...

...Systems In this paper we will provide an overview and history of computer and network security. We will identify one current use of computer and network security and provide an example of this concept in practical use. A discussion of attitudes towards computer and network security will be made and justifications towards the attitude. We will explain the fundamental strengths and weaknesses toward computer and network security and will provide expert views regarding computer and network security. An overview of the origin and history of computer and network security. Lately enthusiasm for security was energized by the wrongdoing submitted by Kevin Mitnick. Kevin Mitnick carried out the biggest computer related wrongdoing in U.S. history. The misfortunes were eighty million in United States dollars, and licensed innovation and source code from a mixture of organizations. From that point forward, data security came into the spotlight. Open systems are being depended upon to convey budgetary and individual data. Because of the development of data that is made accessible through the web, data security is moreover needed to develop. Because of Kevin Mitnick's offense, organizations are underscoring security for the protected innovation. The web has been a driving power for information security change. Web conventions in the past were not developed to secure themselves. Inside of the TCP/IP correspondence stack, security protocols are not actualized which leaves the network open to assaults...

...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...

...Computer Security Victoria M. Deardorff Brevard Community College April 10, 2012 This paper is written as a basic overview of computer security for the non-technical user. This paper is meant to educate the reader on practical steps that can be implemented to secure their home-based computers. Additionally, the reader will be informed of industry and government needs for and methods of computer security. With this information, the reader should gain a better understanding of why agencies and companies have their rules and regulations pertaining to computer security. What do you think when you read or hear the words “computer security”? The word security implies freedom from risk, danger, doubt, anxiety, or fear and invokes a feeling of safety and confidence. As security relates to our computers, you may immediately ask yourself if you have done everything possible to guard your personal computer as well as the information stored on that computer. Also, you may think about the companies with which you do business and ask the same question; have they done everything possible to protect my personal information? The world of computer security or information security, as it is sometimes called, continues to evolve as consumers expand the use of computer systems. “The story of network attacks, bugs, viruses, and criminal actions stretches as far as the computer industry itself. One of the first bugs to develop in a computer system was precisely that: a moth was found...

...What is Ethical Hacking Ethical hacking provides a way to determine the security of an information technology environment – at least from a technical point of view. As the name ethical hacking already tells, the idea has something to do with hacking. But what does “hacking” mean “The word hacking has two definitions. The first definition refers to the hobby/profession of working with computers. The second definition refers to breaking into computer systems. While the first definition is older and is still used by many computer enthusiasts(who refer to cyber-criminals as "crackers"), the second definition is much more commonly used.” – Definition by Internet Security Systems In the context of “ethical hacking”, hacking refers to the second definition –breaking into computer systems. It can be assumed that hacking is illegal, as breaking into a house would be. At this point, “ethical” comes into play. Ethical has a very positive touch and describes something noble which leads us to the following definition of ethical hacking: Ethical hacking describes the process of attacking and penetrating computer systems and networks to discover and point out potential security weaknesses for a client which is responsible for the attacked information technology environment. An ethical hacker is therefore a “good” hacker, somebody who uses the methods and tools of the blackhat4 community to test the security of networks and servers. The goal of an ethical hack is neither to do damage...

...Hardening client computers is essential when you are using a multi platform based network. Hardening is simply creating security lockdown protocols that will deter any intrusion from the outside and inside of a network. There are several ways to deploy those hardening settings the Security Configuration Wizard Graphic User Interface (SCW GUI), the Scwcmd command line deployment tool, and the Group Policy object (GPO). We will be discussing the GPO deployment method. This hardening procedure is required to maintain a secure operating system and network environment as a network firewall cannot prevent all intrusion that need to be stopped. When using the GPO to deploy security setting to another client computer there are some things that need to be done in order for the set up to be successful. There will be the need for a security risk assessment to be conducted to determine what will need to be protected against and what type of protection levels will need to be implemented. How the hardening (security) policies will be created and deployed to client computers. What type of operating systems is on the network in order to test the policy before it is deployed? With these question answered the hardening process can begin. First the servers and client computers must have the latest updates from their respective software company then the policies must be defined and tested for security to ensure they meet the requirements set forth in the security risk assessment...
