Study on Ethical Hacking and Penetration Testing

Study on Ethical Hacking and Penetration Testing

Ethical hacking refers to the act of tracing 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. Hacking is an activity in which, a person exploits the weakness in a system for self-profit or enjoyment. As public and private organizations migrate more of their critical functions or applications such as electronic commerce, marketing and database access to the Internet, then hackers have more opportunity and incentive to gain access to sensitive information through the Web application. Thus the need of protecting the systems from the hacking generated by the hackers is to promote the persons who will punch back the illegal attacks on our computer systems. Ethical hacking is an identical activity which aims to find and rectify the weakness and vulnerabilities in a system. Ethical hacking describes the process of hacking a network in an ethical way, therefore with good intentions. This paper describes what is ethical hacking, what are the types of ethical hacking, impact of Hacking on Businesses and Governments and penetration testing used for protection form hackers .

Ethical Hacking Techniques with Penetration Testing

Ethical Hacking Techniques with Penetration Testing

As cyber attacks[3]increase, so does the demand for information security professionals who possess true network penetration testing[2]and ethical hacking skills. There are several ethical hacking courses that claim to teach these skills, but few actually do. SANS SEC560: Network Penetration Testing[2]and Ethical Hacking truly prepares you to conduct successful penetration testing and ethical hacking projects. The course starts with proper planning, scoping and recon, and then dives deep into scanning, target exploitation, password attacks, and wireless and web apps with detailed hands-on exercises and practical tips for doing the job safely and effectively. You will finish up with an intensive, hands-on Capture the Flag exercise in which you'll conduct a penetration test against a sample target organization, demonstrating the knowledge you mastered in this course. Ethical hacking does perfectly fit into the security life cycle (see Fig 1). Ethical hacking is a way of doing a security assessment – a current situation (from atechnical point of view) can be checked. Like all other assessments (or audits),an ethical hack is a random sample and passing an ethical hack doesn’t mean there are no security issues. An ethical hack’s results is a detailed report of the findings as well as a testimony that a hacker with a certain amount of time and skills is or isn’t able to successfully attack a system or get access to certain information. With the growth of internet, computer security is of utmost concern for the organizations and government. These organizations are using Internet in their wide variety of applications such as electronic commerce, marketing and database access. But at the same time, data and network

Wireless Local Area Network Security Enhancement through Penetration Testing

Wireless Local Area Network Security Enhancement through Penetration Testing

Attacks on WEP: WEP is considered a weak technique for WLANs security since it uses RC4, a stream cipher that simply performs XOR operation on the data. The key XOR plaintext gives ciphertext, so a bit-flipping attack can make ciphertext XOR and key give the plain text easily. Another vulnerable aspect for the WEP is the use of the CRC-32 mechanism used for the integrity check. Cyclic redundancy code (CRC) is defined as a class of "checksum" algorithms that treat any message as a large binary number and then dividing it in binary without overflow by a fixed constant. The remainder is called the "checksum". Due to the nature of CRC that considered being linear, it fails to provide the required integrity protection. It is known that CRC is not cryptographically strong and not intended to be used in place of the message digest or hash functions. It uses the 24-bit long initialization vector (IV) that is clear text added to the packet, and then it is ready to be transmitted through the air where it can be exposed to an FMS attack. WEP suffers from a lack of mutual authentication and key management due to the small size of IV (24 bit), the weak authentication algorithm and the weak data encapsulation method. This paper will perform a penetration test that proves WEP has failed as a wireless security protocol due to its lack of integrity and confidentiality of data [10].

The Importance Of Ethical Hacking

The Importance Of Ethical Hacking

For example, an external penetration test is a valuable starting point for the majority of businesses. This provides a real-world assessment of the many threats that an organisation faces in its daily operations. However, organisations such as manufacturing or utilities companies have minimal Internet-facing communications and would derive more value from internal penetration tests. If possible, businesses should begin with smaller, external penetration testing projects when first contracting an ethical hacker. This pilot project will reduce cost and risk while providing valuable insight into the ethical hacker’s skills and professionalism. Customers should then expand the scope of their penetration tests as they become more familiar with ethical hacking services. This process is illustrated in Chart 3 below.

Security, Trust and Risk Why Ethical Hacking?

Security, Trust and Risk Why Ethical Hacking?

There are many different terms used for security testers, specifically those who perform intrusive testing which is intended to compromise and analyse your security. Penetration testing, ethical hacking, tiger teaming, red teaming, blue teaming, information or digital assurance testing and vulnerability analysis are just some buzzwords to describe essentially the same thing. The list is nearly as long as the variations in products and tests. This document will attempt to shed some light on what you should expect from an ethical hacker, why you would want to use one and to give you guidance on how to project manage a successful security test.

The Ethical Hack   A Framework for Business Value Penetration Testing pdf

The Ethical Hack A Framework for Business Value Penetration Testing pdf

Unfortunately, it is common for organizations to consider network- and host-based security programs as sufficient security. In reality, these types of focused programs are subsets of an information security program, dealing with the specific risks involved with the transport, processing, and storage of an organization’s information. A comprehensive security program must also consider, for example, physical security, including physical access controls and physical media handling procedures. Although much attention is traditionally lavished on logical controls such as firewalls and access lists, perceptive hackers are fully aware that information can potentially be obtained through activities such as dumpster diving. Every day confidential printouts and unsanitized magnetic media are thrown out by unsuspecting organi- zations with stellar network security controls but marginal information security controls. Understanding not only the company’s digital assets and logical and phys- ical controls, the expected management of risk based on the security program provides a substantial supporting element to the employment of a penetration test. Another aspect often overlooked is the organization’s personnel. Typically, an organization will be very cognizant of education and experience requirements for personnel, and some industries may require varying degrees of background checks. This only establishes their credibility and suitability to perform their jobs, but does not address information security in any meaningful way. Unless the level or status of the employees is directly related to their roles with regard to information use, access, responsibility, and other security concerns related to digital assets, the role of the employee and the investigative employment process has little measurable support for information security.

Cyber Security and Ethical Hacking

Cyber Security and Ethical Hacking

[10]Gary Hall - Erin Watson summarizes hacking is one of the most misunderstood cyber concepts. The majority of people think of hacking as something evil or illegal, but nothing could be farther from the truth. Indeed, hacking can be a real threat, but if you want to stop someone from hacking you, you must also learn how to hack.[12] Seth McKinnon gives abstract about methods and techniques such as penetration testing, Wi-Fi hacking and DOS attacks in order to provide a better understanding in how to hack and ultimately prevent your computer from being an easy target.[] Chuck East tom brings together up-to-the-minute coverage of all basic concepts, terminology, and issues, along with all the skills you need to get started in the field. Drawing on his extensive experience as a security instructor and consultant, East tom thoroughly covers core topics, such as vulnerability assessment, virus attacks, hacking, spyware, network defense, passwords, firewalls, VPNs, and intrusion detection. Computer Security Fundamentals, Second Edition is packed with tips and examples, all extensively updated for the state-of-the-art in both attacks and defense .This book will help you protect your systems and data and expand your career options [20].

Ethical Hacking Introduction

Ethical Hacking Introduction

The other school of thought here is that malicious tools can be used by network administrators to harden their systems and this is really the basic premise of ethical hacking. It's being able to use tools that are out there on your own networks to increase the security of it, to defend those networks and make sure they're secure. So if you think about it, logically it kind of makes sense. You know that there are bad guys out there doing stuff to your networks. You know that they're hacking in. You know that they're running certain tool sets. Why not take that tool set and apply it to your own network to see, one, how your network responds to it, how your own defenders respond to it; can they detect this stuff? Can they respond to it? Do they analyze it correctly?

Some of the more famous Black Hat hackers from the past were able to turn their misfortune into a profitable career after serving time behind bars, or after completing probation. Today, that quick ride to fame and wealth is pretty much nonexistent. One site worth perusing is the “Computer Crime & Intellectual Property Section” of the U.S. Department of Justice Web site (www.usdoj.gov/ criminal/cybercrime/cccases.html). There, you will find a list of current computer crime cases as well as those dating back to 1998. Included in the list is an estimate (in dollars) of damages and the punishment for the criminal act. There, you will find a range of punishments from 0 months to 108 months (U.S. versus Salcedo et al., for breaking into Lowe ’ s computer network with intent to steal credit card information) and fines ranging from $0 to $7.8 million (U.S. versus Osowski, accountants who illegally issued shares of Cisco stock to themselves). Yes, the possibility of making money illegally exists; however, the punishment associated with getting caught is meant to discourage such activities. And as time goes by, more laws are being added to make the punishment for computer crimes much more severe.

white. They are those who have the ethics. The Gray Hat hacker collects information and comes into the computer system to improve the security to notify the administrator of security breaches and to inform that the system may be compromised. Then they can provide a treatment themselves. They know exactly what is right and what is wrong, but sometimes they do negative. Gray Hat can remove the computer security of businesses and can use and process them. However, they usually make changes to existing programs that can be corrected. After a while, they are themselves responsible for the security vulnerabilities of the company. Hack an or get unauthorized entries on the network just for fun and not for the structure of organizations damaged by the network. When hacking a system, independent of piracy (piracy) or piracy (black piracy), the hacker should follow some steps to access the computer system that can be analyzed as following.

Implementing IT Security Penetration Testing in Higher Education Institute

Implementing IT Security Penetration Testing in Higher Education Institute

With the increasing importance of information systems in today’s complex virtual environment, university’s have to perform a higher level of due diligence to ensure the confidentiality, integrity and availability of the customer information and university’s IT services. University Teknologi MARA Pahang, Jengka Campus is one of Malaysian Government Higher Education Institute located in the state of Pahang, eastern Malaysia. As one of the fast growing university in terms of number of graduated students and latest research developments and findings, the university’s holds critical and real time data for its stakeholders such as student information, administration information, research findings and other web applications. In a personal interview with Ibrahim in 2012, said a couple of successfully compromised and exploited attacks were reported in the university’s server that led to the misuse of the server as the phishing activities. The university’s management personnel believed that the attacker could be from internal or external of the target environment. The lack of awareness for securing universities’ information and network infrastructure is reported by experts in computer security which agree that, related to computer, universities are among the least secure places in the universe (Foster, A.L., 2004). In addition, (North, M., 2006) show in their research that audits of the university security systems reveal a large number of weaknesses. Therefore, the safeguard and prevention of the university’s IT infrastructure and services must be enhanced.

2000, news sources reported an attack against Microsoft's internal systems, targeting its source code. In May 1999, the FBI investigated several hacking groups based in the United States. After the FBI seized a suspected teenage hacker's computer, several hacker groups retaliated by defacing government Web sites. At one point, a DoS attack caused the FBI Web site to be taken offline for seven days. [5] In January 2000, an Internet hacker threatened CD Universe, stating that if the company did not pay a ransom of $100,000 he would publish 300,000 credit card numbers he stole from its Web site. The company refused to pay the ransom and the hacker published over 25,000 credit card numbers. This attack destroyed consumer confidence in CD Universe and added to the mistrust consumers already have in online buying. Between the middle of 1999 and the beginning of 2000, computer viruses such as Melissa, I LOVE YOU, and Explorer.zip devastated corporate networks, forcing companies to shut down for days to combat the viruses. These viruses demonstrated the frailty of present-day virus scanners and how easy it is to get users to execute malicious code. The incidents also illustrated the problems and losses a company can suffer from an attack.

system that would be able to survive a nuclear attack (Hafner and Lyon, 1998), with a protocol that originally allowed a maximum of 1,000 users. On October 29, 1969, computers at Stanford and UCLA linked online for the first time. The first ever message to be sent was intended to say the word ‘login’; however the system has been widely reported to have crashed on the letter ‘g’ (ibid, 1995). As the network was initially only used for ARPA research purposes, it was not designed with security in mind, it was designed to be open, to be robust and to be flexible. The network initially linked only a few government and university PC’s and was used for simple tasks including e-mail, remote connection and e-newsgroups. By 1971, the ARPANET network linked approximately fifteen nodes, with the first international connections made in 1973 (Weber, 2003). Where ARPANET was a single network, the internet was destined to be a network of networks. In 1989, ARPANET became the ‘internet’ with the addition of a number of other networks, at this time over 100,000 host PC’s were linked to the network (Weber, 2003) In the early 1970s technologies that allowed people to use de-centred, distributed networks of computers to communicate with each other were developed alongside the development of hardware (Levy, 1984). Late in the 1970s, a means by which the different networks of computers could be connected to each other was developed, the Internet, and a worldwide network of computers became a reality (Hafner and Lyon, 1998; Quarterman, 1990). TCP/IP, the protocol which allowed this was first used in 1983 on ARPANET at which time MILNET replaces ARPANET in the hosting of military networks (Weber, 2003).
