Ethical Hacking - Computing and Software Wiki. Sounds Of Polynesia Zero G Chair there. From Computing and Software Wiki.Ethical Hacking, also known as penetration testing, intrusion testing, or red teaming, is the controversial act of locating weaknesses and vulnerabilities of computer and information systems by duplicating the intent and actions of malicious hackers. An Ethical Hacker, also known as a whitehat hacker, or simply a whitehat, is a security professional who applies their hacking skills for defensive purposes on behalf of the owners of information systems. Nowadays, certified ethical hackers are among the most sought after information security employees in large organizations such as Wipro, Infosys, IBM, Airtel and Reliance among others. What is Ethical Hacking? Definition Ethical hacking refers to the act of locating weaknesses and vulnerabilities of computer and information systems by duplicating the intent and actions of malicious hackers. Ethical hacking is also known as penetration testing, intrusion testing, or red teaming. An ethical hacker is a security professional who applies their hacking skills for defensive purposes on behalf of the owners of information systems. By conducting penetration tests, an ethical hacker looks to answer the following four basic questions [1] . What information/locations/systems can an attacker gain access? What can an attacker see on the target? What can an attacker do with available information? Does anyone at the target system notice the attempts? An ethical hacker operates with the knowledge and permission of the organization for which they are trying to defend. In some cases, the organization will neglect to inform their information security team of the activities that will be carried out by an ethical hacker in an attempt to test the effectiveness of the information security team. This is referred to as a double- blind environment. In order to operate effectively and legally, an ethical hacker must be informed of the assets that should be protected, potential threat sources, and the extent to which the organization will support an ethical hacker's efforts [2]. Ethical Hacking History Since the 1. Internet has vastly grown in popularity and computer security has become a major concern for businesses and governments. Organizations would like to use the Internet to their advantage by utilizing the Internet as a medium for e- commerce, advertising, information distribution and access, as well as other endeavors. However, they remain worried that they may be hacked which could lead to a loss of control of private and personal information regarding the organization, its employees, and its clients. In a search for ways to reduce the fear and worry of being hacked, organizations have come to the realization that an effective way to evaluate security threats is to have independent security exerts attempt to hack into their computer systems. In the case of computer security, these tiger teams or ethical hackers would use the same tools and techniques as an attacker, but rather than damage the system or steal information, they would evaluate the system security and report the vulnerabilities they found and provide instructions for how to remedy them [3]. From the early days of computers, ethical hacking has been used as an evaluation of system security. Many early ethical hacks were conducted by the United States Military to cary out security evaluations on their operating systems to determine whether they should employ a two- level (secret/top secret) classification system. However, with the growth of computing and networking in the early 1. In December of 1. Dan Farmer from Elemental Security and Wietse Venema from IBM, suggested that the techniques used by hackers can be used to asses the security of an information system. They wrote a report that was shared publicly on the Internet which described how they were able to gather enough information to compromise security and they provided several examples of how this information could be gathered and exploited to gain control of a system, and how such an attack could be prevented. Farmer and Venema realized that the testing that they had performed was complex and time- consuming, so they packaged all of the tools that they had used during their work and developed an easy- to- use application free for download. Their program, called Security Analysis Tool for Auditing Networks, or SATAN, received a great amount of media attention due to its capabilities and implications. The SATAN tool provided auditing capability as well as capabilities to provide advice regarding how the user may be able to correct the problems that were discovered. The Ethical Hacking Process Ethical hackers must follow a strict scientific process in order to obtain useable and legal results [4]. Planning Planning is essential for having a successful project. It provides an opportunity to give critical thought to what needs to be done, allows for goals to be set, and allows for a risk assessment to evaluate how a project should be carried out. There are a large number of external factors that need to be considered when planning to carry out an ethical hack.These factors include existing security policies, culture, laws and regulations, best practices, and industry requirements.Each of these factors play an integral role in the decision making process when it comes to ethical hacking. . The planning phase of an ethical hack will have a profound influence on how the hack is performed and the information shared and collected, and will directly influence the deliverable and integration of the results into the security program.The planning phase will describe many of the details of a controlled attack.It will attempt to answer questions regarding how the attack is going to be supported and controlled, what the underlying actions that must be performed and who does what, when, where, and for how long.Reconnaissance Reconnaissance is the search for freely available information to assist in an attack. This can be as simple as a ping or browsing newsgroups on the Internet in search of disgruntled employees divulging secret information or as messy as digging through the trash to find receipts or letters. Reconnaissance can include social engineering, tapping phones and networks, or even theft. The search for information is limited only by the extremes at which the organization and ethical hacker are willing to go in order to recover the information they are searching for. The reconnaissance phase introduces the relationship between the tasks that must be completed and the methods that will need to be used in order to protect the organization's assets and information. Enumeration Enumeration is also known as network or vulnerability discovery. It is the act of obtaining information that is readily available from the target's system, applications and networks.It is important to note that the enumeration phase is often the point where the line between an ethical hack and a malicious attack can become blurred as it is often easy to go outside of the boundaries outlined in the original attack plan. A Chave Do Segredo Livro Downloads . In order to construct a picture of an organization's environment, several tools and techniques are available. These tools and techniques include port scanning and NMap. Although it is rather simple to collect information, it is rather difficult to determine the value of the information in the hands of a hacker. At first glance, enumeration is simple: take the collected data and evaluate it collectively to establish a plan for more reconnaissance or building a matrix for the vulnerability analysis phase. However, the enumeration phase is where the ethical hacker's ability to make logical deductions plays an enormous role. Vulnerability Analysis In order to effectively analyze data, an ethical hacker must employ a logical and pragmatic approach. In the vulnerability analysis phase, the collected information is compared with known vulnerabilities in a practical process. Information is useful no matter what the source. Any little bit can help in discovering options for exploitation and may possibly lead to discoveries that may not have been found otherwise. Known vulnerabilities, incidents, service packs, updates, and even available hacker tools help in identifying a point of attack. The Internet provides a vast amount of information that can easily be associated with the architecture and strong and weak points of a system.
