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

Analysis of Various tools of Penetration Testing Harshdeep Singh 1, Jaswinder Singh2

Analysis of Various tools of Penetration Testing Harshdeep Singh 1, Jaswinder Singh2

The penetration testing is a next step to the vulnerability assessment process of network penetration under which the vulnerabilities are located and assessed before doing the penetration into the system. The penetration tests are carried out intentionally to have a potential knowledge of the threats in the system composition of security that can be used by a hacker or cyber professional for hacking the system [2]. The aim of authorized exploitation of the system is the safe keeping of the personal information of an organization or company so that it cannot fall into the wrong hands. The penetration testing introduces with the weak links that are present in the programming and designing of the security. It helps in ensuring the strong defense of the system against any kind of flaws related to the security of the system by suggesting measures or solutions to the problems related to the network security. Ettercap, Driftnet, Nmap, Wireshark, Metasploit are certain tools which are used in the process of penetration testing [3]

The Hacker Playbook, Practical Guide To Penetration Testing pdf

The Hacker Playbook, Practical Guide To Penetration Testing pdf

Kali is a Linux penetration distribution (or “distro” for short), which contains a lot of the common tools utilized for penetration testing. This is probably seen as the standard right now in the security community and many people are building off this framework. I agree that Kali does have a lot of the tools that’d I typically use, but I added a few tools of my own. Some of the binaries like Windows Credential Editor (WCE) might already be on the Kali distro, but I like to make sure that I am downloading the most recent version. I try to also make sure to keep the binaries I modify to evade AV in a separate folder so that they don’t get overwritten.

Discrete element modelling and cavity expansion analysis of cone penetration testing

Discrete element modelling and cavity expansion analysis of cone penetration testing

This paper uses the discrete element method (DEM) in three dimensions to simulate cone penetration testing (CPT) of granular materials in a calibration chamber. Several researchers have used different numerical techniques such as strain path methods and finite element methods to study CPT problems. The DEM is a useful alternative tool for studying cone penetration problems because of its ability to provide micro mechanical insight into the behaviour of granular materials and cone penetration resistance. A 30° chamber segment and a particle refinement method were used for the simulations. Giving constant mass to each particle in the sample was found to reduce computational time significantly, without significantly affecting tip resistance. The effects of initial sample conditions and particle friction coefficient on tip resistance are investigated and found to have an important effect on the tip resistance. Biaxial test simulations using DEM are conducted to obtain the basic granular material properties for obtaining CPT analytical solutions based on continuum mechanics. Macro properties of the samples for different input micro parameters are presented and used to obtain the analytical CPT results. Comparison between the numerical simulations and analytical solutions show good agreement.

163 The Basics Of Hacking And Penetration Testing [ PUNISHER ] pdf

of course it should go without saying that in this example both of these flaws should be reported. However, the point is that in this case one flaw clearly presents more danger than the other. in this situation, many newcomers may be tempted to showcase their technical skills and successes by emphasizing the fact that they were able to successfully compromise a server and downplay the importance of the critical vulnerability because the penetration tester was unable to exploit it. never put yourself or your ego above the security of your clients. do not overstate the facts; simply report your findings to the best of your ability in an objective manner. let them make subjective decisions with the data you provide. never make up or falsify data in a penetration test. never reuse “proof-of-concept” screenshots. it can be tempting to take shortcuts by supply- ing generic, reusable proofs, but it is a dangerous and unethical thing to do. the idea and use of proof-of-concept screenshots is a powerful tool and should be incorporated into the penetration testing report whenever possible. Anytime you discover a major finding or successfully complete an exploit, you should include a screenshot in the detailed report. this will serve as undeniable evi- dence and provide the reader with a visualization of your success.

Agent-based (BDI) modeling for automation of penetration testing

Agent-based (BDI) modeling for automation of penetration testing

In recent years, malicious network attacks have become an increasingly serious threat to individuals, businesses and even national information security. Penetration testing [1] is a methodology which simulates real attacks with the aim to assess the security of computer systems and networks. The main distinction between an attacker and penetration testing depends on the legality. In other words, penetration testing aims to improve the security of the system rather than destroy or access information illegally and it does not affect the availability of target systems. The process of penetration testing is normally done manually, and the test cycle is relatively long. Moreover, the test results are highly dependent on the level of skill and experience of a tester or penetration team. To improve the efficiency, automated penetration testing methods and tools are needed. The automation can significantly reduce the time, cost and human involvement in the process of information gathering, analysis and exploitation.

Hacking the next web: penetration testing over IPv6

Hacking the next web: penetration testing over IPv6

The first sub-question concerns how the current penetration testing process is affected when IPv6 is used: what components need to be modified in order to achieve their goal, or can be removed because they become obsolete. For each component of Pine’s penetration testing process, the performed activities are examined to determine how they are affected by a change to IPv6. This is done by analyzing the dependencies of every action performed, to see if functions specific to IPv4 are relied upon. A suggestion for removal from the process or modification is made per activity that is found to be affected. By following this approach, we determine what components of the current penetration testing process are affected, but we do not discover new additions.

Vulnerability Assessment and Penetration Testing in Web Application and Its Prevention

Vulnerability Assessment and Penetration Testing in Web Application and Its Prevention

name suggests, aims at discovering the possible threats and subset of input space with which a malicious user can exploit logical errors in a system to gain profit or drive the system into an insecure state. While, Penetration testing, aims at assessing the difficulty level for someone (basically an attacker/hacker) to penetrate an Organization's Cyber security controls against unauthorized access to its information and information systems. VAPT is done by simulating an unauthorized user (attacker) attacking the system using either Automated Tools or Manual Excellence or a combination of both. Hence the process of VAPT is sometimes also referred as Ethical Hacking. VAPT helps in identifying Cyber Threats and vulnerabilities under controlled circumstances, so that they can be eliminated before actual hackers/attackers aim to exploit them [2].

The Ethical Hack   A Framework for Business Value Penetration Testing pdf

The Ethical Hack A Framework for Business Value Penetration Testing pdf

Losses associated with viruses remain a pain for customers: 82 percent of respondents to the CSI/FBI 2003 Eighth Annual Security Survey cited viruses as their problem in the last 12 months. Although 99 percent of respondents use antivirus software, 47 percent reported losses of $27.3 million. Viruses and worms represent tremendous threats to the continued security of organizations even in the face of arguably comprehensive controls. In recent papers and articles, there is a clear association with the security state of a system (application, operating system, servers, etc.) and the proliferation and impact of viruses and worms, which are often based on vulnerabilities. Therefore, patch management and system hardening are becoming the next effective layer in a “defense in depth” security strategy. This begins to explain the popularity of vulnerability tools and services, such as penetration testing. Vulnerabilities are increasing in number and severity. The ability to manage your vulnerabilities and reduce overall exposure is key to the survival of any organization. To do so requires regular risk analysis and appropriate alignment of security man- agement to business needs and exposures. Considering that not all vulnerabilities can be identified, and the ones that can are not always avoidable (e.g., repairable), the effectiveness of a risk analysis in guiding security operational attributes is core to the overall protection of the company’s business. Demonstrated in Figure 2.2, from Symantec’s annual vulnerability report, the number and severity of identified vulnerabilities is climbing. This is a representation of the threats to organizations globally and the demand for maintaining a security posture.

Effective Penetration Testing Approach for Modern Web Application Vulnerabilities

Effective Penetration Testing Approach for Modern Web Application Vulnerabilities

Before studying penetration testing of web application, one should know about the 2 basic terms that are vulnerability and vulnerability assessment. The term Vulnerability is defined as the flaw or the weakness in the web application that could be subjugated to compromise its security. Attacks against web applications vulnerabilities are mainly to expose sensitive data or in order to gain unhampered access to the back end systems on which the application is running. While the second term Vulnerability Assessment refers to the 3 step process which includes identification, quantification and report creation phase. In identification phase, numbers of vulnerabilities are acknowledged and then in quantification phase, task of rating them according to technical severity rather than taking into account the affected business and its mission critical process is done. At last documentation or report is created. Vulnerability

Penetration Testing Professional Ethics: a conceptual model and taxonomy

Penetration Testing Professional Ethics: a conceptual model and taxonomy

The penetration tester should act with integrity at all times. In his endeavours, as noted, the penetration tester should strive to maintain a degree of separation between the criminal hacker and the security professional; thereby to uphold the profession. The penetration tester can be seen to be acting with integrity if they can be seen to be upholding the profession. To further clarify figure 2 suppose the penetration tester builds non-disclosure and limited liability into the testing contract, they can ergo be seen binding their ethics legally and thereby ethically serving and protecting the client. To ethically serve and protect the client is to act with integrity. Integrity is therefore the synergising foundation from which the professional ethics of penetration testing extend. If the penetration tester refuses to engage with the criminal hacking fraternity they can be seen to be using their skills for commissioned tests only and therefore upholding the profession.

Study on Ethical Hacking and Penetration Testing

Study on Ethical Hacking and Penetration Testing

Ethical hacking is an extensive term that covers all hacking techniques, and other associated computer attack techniques. So, along with discovering the security flaws and vulnerabilities, and ensuring the security of the target system, it is beyond hacking the system but with a permission in order to safeguard the security for future purpose. Hence, we can that, it is an parasol term and penetration testing is one of the features of ethical hacking. 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. Ethical hacking can be categorized as a security assessment, a kind of training, a test for the security of an information technology environment. An ethical hack shows the risks an information technology environment is facing and actions can be taken to reduce certain risks or to accept them. We can easily say that Ethical hacking does perfectly fit into the security life cycle shown in the below figure

Seven Phrase Penetration Testing Model

Seven Phrase Penetration Testing Model

Penetration testing is like the annual physical at your doctor’s office. There are many diagnostic tools are available to test the system, much like a blood test or an X-ray. A blood test will check for many things, but it still takes a doctor to review the data, make inferences, perform additional tests and then reach a diagnostic conclusion. Tools will test for many things, but it will always take a human to review the results and make inferences based on knowledge and experience that will never be able to put in a tool [22]. The proposed penetration testing model is providing the accurate way, well arranged and planed process of the penetration testing procedure. As a result from seven phrase penetration testing model, the tester can do better work in less time meaning they can secure more systems without sacrificing the overall quality of their testing. The model is proposed to help, small IT Company so that they can get benefits of penetration testing of their developed product or their network with less cost and automatic and perfectly well directions. The proposed model will helps automate a great deal of the penetration test and provides services and tools to the new penetration testers as well as the seasoned veteran, allowing each to focus on the part of the test they excel at. This creates a business process that allows for the performance of penetration tests in a more efficient and standard way [21][22].
