...Ethical Hacking – Is There Such A Thing? Alexander Nevermind Nelson Stewart, PhD CIS 324 December 9, 2011 ABSTRACT ------------------------------------------------- When someone hears the word hacker, many things come to mind. Bad, thief, terrorist, crook and unethical are some words that may be used to describe a hacker. The reputation of a hacker is well deserved as many company networks have been compromised with viruses and spyware causing untold millions in damage, the theft of sensitive consumer information such as Social Security numbers and financial data and the unauthorized access of classified government information. To combat these issues, many companies employ individuals called ethical hackers who, by their direction and supervision look for vulnerabilities in network systems. There are naysayers who bristle at the term “ethical hacker” saying that a hacker is a hacker but those who hold such views could be missing the point. These subjects will be discussed in detail later in the text. ------------------------------------------------- Is there such a thing as “Ethical Hacking?” Define ethical hacking and support an argument in favor or against the concept. Consider who might believe/use ethical hacking and discuss if hacking, even for the purpose of protecting human rights, is ethical. You should extend the paper beyond the topics suggested in the questions within the paper description. Ethical hacking does exist, in fact, companies...

...2014 Ethical Hacking Ethical hacking is used to describe hacking performed by a company or individual to help identify potential threats on a computer or network. An ethical hacker works passed the system security to detect the vulnerabilities or weak points of a company’s network. Then this type of information is used to improve the company’s network from the bad hackers who exploit the company in a destructive way. In 1960s, U.S military began testing their own IT systems, but when Dan Farmer a security expert from San Francisco and a security programmer at the Netherlands University of Eindhoven had posted the techniques they used to gather information to the Usenet, that could have compromised the security of a number of target networks(Langely). Their goal was to raise the overall level of security on the internet. Dan farmer and Eindhoven were elected to share their work freely on the internet for others to learn. Eventually, they gather up the work they used and developed a program called Security Analysis Tool for Auditing Networks (Langely). This tool is used to perform an audit of the vulnerabilities of the system and how to eliminate the problem. The concept of ethical hacking started emerging in 1993 (Langely). According to some, ethical hacking does not exist and they feel hacking is just hacking, no matter how you put it. Therefore the one that is doing the hacking is a computer criminal. This is not the case, so in order for hacking it to be “ethical “you...

...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...

...As the internet is growing there has been a higher demand for network security. With the higher demand comes a new form of job known as ethical hacking. An ethical hacker is a person that conducts penetration testing on networks to test the integrity of a network for any given business or corporation (White hat (computer security)). With this technique, corporations and businesses will have the assurance they need for protecting their personal identifiable information (PII) on their network. To beat a hacker, first you must think like one. Ethical hacking is an accepted hacking method of network security systems for a particular business or corporation. Ethical Hacking has provided network security administrators with the knowledge they need to continually keep their network secure. With this method of penetration testing, you can see that there is no negative effect on a business or corporation’s network security. The ethical hacker must first receive authorization. If authorization is not obtained, ethical hacking can be considered a federal offense punishable by a prison sentence of no less than five years (Computer Hacking Law & Legal Definition). “The authorization can be as simple as an internal memo or e-mail from your boss if you're performing these tests on your own systems. If you're testing for a client, have signed contracts in place, stating the client's support and authorization” (Beaver). Once authorization has been made you will need to develop a strategy...

...Importance of ethical hacking Chapter 1 Introduction Ethical hacking is an emerging tools used by most of the organizations for testing network security. The security risks and vulnerabilities in a network can be recognized with the help of ethical hacking. This research completely concentrates on ethical hacking, problems that may occur while hacking process is in progress and various ethical hacking tools available for organizations. Information is the important source for any organizations while executing business operations. Organizations and government agencies have to adopt ethical hacking tools in order secure important documents and sensitive information (Harold F. Tipton and Micki Krause, 2004). Ethical hacker professionals have to be hired in order to test the networks effectively. Ethical hackers perform security measure on behalf of the organization owners. In order to bring out the ethical hacking efforts perfectly a proper plan must be executed. Ethical hacking has the ability to suggest proper security tools that can avoid attacks on the networks. Hacking tools can be used for email systems, data bases and voice over internet protocol applications in order to make communications securely. Ethical hacking can also be known as penetration testing which can be used for networks, applications and operating systems (Jeff Forristal and Julie Traxler, 2001). Using hacking tools is a best method for identifying the attacks before it effect the entire organization. Ethical hackers...

...Ethical Hacking Computer Ethics – CIS 324 Dr. Nelson Stewart June 7, 2013 INTRODUCTION When most people hear the term “hacker” they think of an evil person committing crimes by hacking into their computers to steal, destroy and/or steal identities. This is so in some cases, but not all hackers are bad. Hackers are merely curious technically skilled individuals who gain unauthorized access to computers, networks of various companies, organizations and individuals. Good hackers are considered white hat hackers. They are the ones that are hired to break into systems as a way of testing the vulnerabilities and security issues that may be present in the computer system. Bad hackers are considered black hat hackers. They are the “evil” hackers, or should I say “crackers” who hack into systems to steal identities, information, crack into software programs and create nasty viruses. 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.

...Chapter-1 1.0 Introduction With the tremendous advancement of Internet, different aspects of it are achieving the highest peak of growth. An example of it is e-commerce. More and more computers get connected to the Internet, wireless devices and networks are booming and sooner or later, nearly every electronic device may have its own IP address. The complexity of networks is increasing, the software on devices gets more sophisticated and user friendly – interacting with other devices and people are a main issues. At the same time, the complexity of the involved software grows, life cycles are getting shorter and maintaining high quality is difficult. Most users want (or need) to have access to information from all over the world around the clock. Highly interconnected devices which have access to the global network are the consequence. As a result, privacy and security concerns are getting more important. In a word, information is money. There is a serious need to limit access to personal or confidential information – access controls are needed. Unfortunately most software is not bug free due to their complexity or carelessness of their inventors. Some bugs may have a serious impact on the access controls in place or may even open up some unintended backdoors. Security therefore is a hot topic and quite some effort is spent in securing services, systems and networks. On the internet, there is a silent war going on between the good and the bad guys – between the ones...

...Ethical hacking by C. C. Palmer The explosive growth of the Internet has brought many good things: electronic commerce, easy access to vast stores of reference material, collaborative computing, e-mail, and new avenues for advertising and information distribution, to name a few. As with most technological advances, there is also a dark side: criminal hackers. Governments, companies, and private citizens around the world are anxious to be a part of this revolution, but they are afraid that some hacker will break into their Web server and replace their logo with pornography, read their e-mail, steal their credit card number from an on-line shopping site, or implant software that will secretly transmit their organization’s secrets to the open Internet. With these concerns and others, the ethical hacker can help. This paper describes ethical hackers: their skills, their attitudes, and how they go about helping their customers find and plug up security holes. The ethical hacking process is explained, along with many of the problems that the Global Security Analysis Lab has seen during its early years of ethical hacking for IBM clients. T he term “hacker” has a dual usage in the computer industry today. Originally, the term was defined as: HACKER noun 1. A person who enjoys learning the details of computer systems and how to stretch their capabilities—as opposed to most users of computers, who prefer to learn only the minimum amount necessary. 2. One who programs enthusiastically...

...One of the first aspects to consider when determining vulnerabilities are the vulnerabilities that lie within an organization- internal vulnerabilities. Vulnerability assessments allowed Jacket-X Organization to determine prevalent vulnerabilities within their organization. As observed, there were irregularities within the organizations payroll system. Although Human Resources brought it to the attention to the CIO, there was no documentation of fraudulent activity that occurred. After reviewing the current implementation of the payroll process of Jack-X Organization, there were a couple of red flags that were brought to my attention: • Payroll specialists and administrators both have the ability to add employees to payroll directly. • Payroll specialists can change payroll details during validation. • There is too much “power” given to specialists. • Strong possibilities for false time cards to be created. • Time cards can be modified easily. • Payrolls that are deleted are not recorded (needed for audit). • Direct deposit and paycheck generation systems are not linked. • Reports are easily exported into an Excel file. These are just some of the vulnerabilities that were noticed. To address these vulnerabilities, the following should be considered: • Have clear and concise polices as to the extent of permissions given to specialists and administrators. If it pertains to any managerial content, they should not be able to access this content. • Prohibit payroll...
