Top PDF Penetration Testing and Vulnerability Assessment

– More focused audits get to the next level of detail; focus on the process and perhaps application level controls (ie. menus); effectiveness testing tends to be more thorough, but lik[r]

Risks to honesty and mystery of information and resources are extended. To remain secured, affiliations perform VAPT to check the security position of the system. As we have encountered the composing review about VAPT systems, it is discovered that there are diverse mechanical assemblies available for performing VAPT. Aggressors are finding better approaches to evade security instruments so new vulnerabilities are propelling which ought to be tended to. In this way existing apparatuses ought to be included with component to perceive and overview the as of late propelled vulnerabilities. This issue can be had a tendency to by making instruments so versatile that new ambush imprints can be included for sorts of vulnerabilities. In Vulnerability Assessment and Penetration Testing utilized for Cyber Security Analysis we begin with contrasting and pointing out similitudes of Vulnerability Evaluation with Entrance Testing with their focal points furthermore, disservices [3]. We have clarified how Vulnerability Evaluation furthermore; Penetration Testing can be utilized as a powerful digital resistance innovation. In future I am planning to find maximum vulnerabilities on websites and then find loopholes and show its prevention will occur.

The following attack was performed using publicly-available software and our origin was successfully masked:. • An outside-in approach was used and it starting with Google[r]

This document was created for electric utilities to use in their security assessment of Smart                             Grid and other energy management systems. Smart Grid security assessments can be                       broken into several categories. This document focuses only on penetration testing and                       attempts to help utilities break down the complex process of penetration testing.                       Penetration testing is a specialized form of hands-­on assessment where the testing team                         takes on the role of the attacker and tries to find and exploit vulnerabilities in systems and                                 devices. Testers use the same methodology that attackers use to identify vulnerabilities in                         a system, which is usually a semi-­blind exploratory interaction with the system looking for                           both previously-­known and previously-­unknown vulnerabilities in the target system. Once a                     vulnerability is found, the testers attempt to exploit the flaw to gain a foothold in the system                                 and begin the process again to discover additional, lower level vulnerabilities that weren’t                         previously exposed. Penetration testing is distinguished from vulnerability assessment                 techniques by the fact that they test for a depth of vulnerabilities instead of simply breadth,                               focus on discovering both known and unknown vulnerabilities, and provide the testing team                         with a better understanding of a particular vulnerability’s risk to the business through the                           vulnerability’s  exploitation.

Based on total number of vulnerabilities, and CVE listed vulnerabilities discovered by each scanner the efficiencies of both Nessus and OpenVAS were calculated. Table 4.8 shows results in percentage of all CVEs vulnerabilities identified by Nessus and OpenVAS. OpenVAS was more effective and efficient at discovering CVEs listed vulnerabilities, than Nessus. Therefore, it was safe to recommend OpenVAS as a reliable and efficient vulnerability scanner. However, Nessus had larger plug-ins database, comprehensive reporting techniques with an extensive pre- defined filtered which made it an interesting option. Further comparison could have given much better idea about the two scanners. Depending upon the time constrains, Penetration tester or Network and System Administrator can perform Scanning and Vulnerability Assessment phase, using either Nessus or OpenVAS or both. Using both scanners can give a better picture of the network or the systems.

day, the threats to the end users is growing rapidly. As the users are increasing there is also a growing need for information security. In order to keep itself and its users safe in the cyberspace, various corporations conduct compliance audits of their systems. A part of the compliance audit is Vulnerability Assessment and Penetration Testing (VAPT). Ethical Hackers test the security of various system components and report it to the management for their further addressable. In order to carry out the tests needed, the Ethical hackers have to use tools to ease their task. These tools run on machines like Desktop or Laptop, which in turn reduces the portability. Cross platform Penetration Testing Suite will facilitate the use of these tools on any mobile device, thus having a testing device in a Ethical hacker’s pocket. The suite will have packages of standard penetration testing tools and a UI will be provided to the end user to use it more efficiently. This suite does not require root access of the user’s phone.

Even experienced wireless security analysts can benefit from the content in this book. For example, many organizations are deploying wireless cameras to improve physical security (while destroying any shred of wireless security in the process). More than just searching for the ever-elusive shower cam (personally, I don’t want to see what goes in on people’s showers), attackers are looking to discover and exploit these unprotected video feeds. I met one researcher who summed up the problems of wireless cameras nicely for me when referring to a wireless camera in a bank: “… if someone wanted to rob the place, all they would need to do is override the signal, and they would never be caught on tape.” Identifying and assessing the exposure of these wireless cameras should be part of any wireless audit or vulnerability assessment (Chapter 11).

Security vulnerabilities in web applications may result in stealing of confidential data, breaking of data integrity or affect web application availability. Thus With the rapid growth of IT development the precaution are also big concerns for the research community against various threats and vulnerabilities. According to sophisticated vulnerability assessment tools 60% vulnerabilities can be found in most of web applications [1]. Even due to automation in form of software many patches and security software are exist in the global world of IT for evade this type of threats such as antivirus, Intrusion detection system, Honey port, Firewall, application filtration software, source code reviewer etc. However the most common way of securing web applications are searching and eliminating vulnerabilities [12]. Another ways of securing web application includes safe development while on other hand efficient way of finding security vulnerabilities from web applications is manual code review. In every approach all the techniques are either more time- consuming or require expert skills, and is prone to overlooked errors. Therefore, security society actively develops automated approaches to finding security vulnerabilities. According to predefined and general approach of testing

It is important to make a difference between penetration testing and network security assessments. A network security or vulnerability assessment may be useful to a degree, but do not always reflect the extent to which hackers will go to exploit a vulnerability. Penetration tests attempt to rival a 'real world' attack to a certain degree. The penetration testers will generally compromise a system with vulnerabilities that they successfully exploited. If the penetration tester finds 5 holes in a system to get in this does not mean that hackers or external intruder will not be able to find 6 holes. Hackers and intruders need to find only one hole to exploit whereas penetration testers need to possibly find all if not as many as possible holes that exist. This is a daunting task as penetration tests are normally done in a certain time frame. Finally, a penetration test alone provides no improvement in the security of a computer or network. Action to taken to address these vulnerabilities that is found as a result of conducting the penetration test.

Gaining and penetration process will consist to exactly exploit the vulnerability found in the previous stage. This process will begin by get some more vulnerability using tools such as web vulnerability scanner. It will help to find other vulnerability which are not find manually during previous stage. All the vulnerabilities is use for addressing in first place the top ten threat define by OWASP which a nonprofit organization other vulnerability will be address even not include in OWASP top then threats. Penetration consist of exploiting the vulnerability found early. Gaining and penetration testing is a crucial process where the asset the web application is tested. The advanced penetration testing should stay in the border defined during the agreement of the penetration testing because some attack against the web application could shut down the web application before those attack is lunch, the attack must have permission from the senior management. As an example of gaining and penetration testing sql injection which is a major vulnerabilities for web application exploit some vulnerabilities and allow the penetration tester to access to the database once the database is accessed then many attack is possible like bypassing authentication mechanism and sensitive data exposure. For each vulnerability identified in previous process it should be exploited according to the limit and using a framework called metasploit It is a good practice to have metasploit framework update because it help to address those vulnerability. Once gained access to web application method of accessing should be correctly document in the final report.

Stepien et al[21] presented an approach to penetration testing for inherent to penetration testing of web pplication hich consists inherent features of TTCN-3 languages. This paper derives the functional test cases and has taken an example of a malicious bank website. This paper has described a message sequence diagram of a malicious bank website to show the XSS attacks. It generate the functional test cases.

We have successfully built LoRa pentest tool ,LoPT. This tool is proven to be effective in our experimental lab setup.The field trail for industrys or Smart cities are never been tried with this tool due to time limitations and resource through physical access.The tool can also be used for sniff- ing ,jamming the LoRa signals transmitted over different frequency channels.The tool also defines an NIDS module which has basic detection techniques to detect rogue devices. LoPT will be an effective pentest tool for LoRa based communication networks .Smart Cities where they used LoRa , we can use this tool to analyze the vulnerability status. Based on the user perspective , this tool can be used to exploit others network or checking strength of their known network. We have more areas to explore in this field of LoRa , which can be done in the future scope.

Habiendo demostrado que el término ethical hacking no tiene por qué ser con- tradictorio, pasemos a analizar en qué consiste. En la sección anterior mencio- namos el vulnerability assessment haciendo foco en el contexto de la informática y las telecomunicaciones. Es un análisis puramente técnico, que suele realizarse en forma remota: el tester prueba la seguridad de los sistemas a través de Internet. Si extendemos el concepto de VA para que quien realiza el análisis pueda tener acceso físico a las instalaciones e interactuar con el personal de la organización, nos encontramos frente a un penetration test o pentest. Un ethical hacker tendrá en cuenta lo mencionado anteriormente y usualmente se pondrá en la piel de un atacante, simulando su comportamiento a fin de evaluar cuán efectivas son las medidas tomadas frente a un ataque.

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

This chapter covers some of the more interesting payload options available with the Metasploit Framework (MSF). Payloads are pieces of code that get executed on the target system as part of an exploit attempt. A payload is usually a sequence of assembly instructions, which helps achieve a specific post-exploitation objective, such as adding a new user to the remote system, or launching a command prompt and binding it to a local port. Specifically, we look in depth at the Meterpreter, PassiveX, and Virtual Network Computing (VNC) dynamic link library (DLL) injection payloads. We also look at the Auxiliary module system, which enables fingerprinting, vulnerability scanning, and other reconnaissance activities to be carried out from within the framework.The objective being to link up the results of these scans, and feed them into the exploitation stage, so that more targeted exploits can be executed with a greater probability of success.

It is common for an attacker to exploit and to penetrate a victim’s system without the owner’s knowledge or consent. This exploit is sometimes achieved by implanting vi- ruses or Trojan via the web or by sending malicious scripts in disguise via email, both of which provide easy ways for an attacker to infect their desired targets. As happened recently, Yahoo network has being hacked silently for two years and more that 5 millions customers information are being stolen. It may happened because of the lack of security awareness and regular security audit/ assessment.

Cross site scripting (XSS) allows the attacker to inject a malicious script (often javascript) in the target website. They allow the attacker to execute undesired function’s in other user’s browser who visits the injected website. XSS attacks can be leveraged to various high severe impacts such as account takeover, credential stealing, data exfiltration, cryptomining, keylogging, fingerprinting, tab-napping, screenshot capture and so on. XSS can be combined with several other vulnerabilities to increase the impact level. During 2005, Samy Kamkar’s Samy worm exploited a Cross site scripting vulnerability in MySpace and affected more than one million users. XSS attacks can be broadly classified into 4 types

identified services that are running on the target. On the other hand, vulnerability scan- ning deals with specific weaknesses in the software or services that have been discovered. The exploitation phase highly depends on the results of the previous two steps. It includes active intrusion attempts which can verify that the found vulnerabilities can indeed be exploited, thus the system is prone to attacks. This step needs to be performed with due care and requires the consideration of potential effects to avoid irreversible harm. The final phase is post exploitation and maintaining access. It covers collecting sensitive information, discovering configuration settings and communication channels that can be used for malicious activity. One of the goals of this phase is to maintain persistent access to the system by setting up a backdoor to access the compromised machine later on [30].
