There are also two important spidering options for submi ing forms. By default, the automated spider will submit all forms that it ﬁnds. I t does not care what the form is for, where it is located, or the ramiﬁcations of submi ing the form several hundred (or thousand) times. I can’t stress this point enough: if the automated spider ﬁnds a form, it will submit it without regard for human life! (O K, that was a tad too dramatic, but you get the point). I f the spider ﬁnds the change password form that does not require the existing password in order to process the auto-ﬁlled new password, you will have an embarrassing call to make to your client to reset your test account. A nother potential sticking point is the Contact U s form that so many website use. I t’s common for the spider to easily submit thousands of emails to the target email server via this form and cause all sorts of heartburn for the receiving company trying to keep their email server running correctly after such an onslaught. Consider using the prompt for guidance option for form submission if you want more granular control of what Burp S pider actually submits to the web application.
In the recent past, numerous high-profile organizations have been compro- mised via their web applications. Though their PR departments may claim they were victims of highly sophisticated hackers, in reality the majority of these attacks have exploited simple vulnerabilities that have been well understood for years. Smaller companies that don’t feel under the spotlight may actually be even more exposed. And many who are compromised never know about it. Clearly, the subject of web application security is more critical today than ever before. There is a significant need for more people to understand web applica- tion attacks, both on the offensive side (to test existing applications for flaws) and on the defensive side (to develop more robust code in the first place). If you’re completely new to webhacking, this book will get you started. Assuming no existing knowledge, it will teach you the basic tools and techniques you need to find and exploit numerous vulnerabilities in today’s applications. If your job is to build or defend web applications, it will open your eyes to the attacks that your own applications are probably still vulnerable to and teach you how to pre- vent them from happening.
Hernan Ochoa is a security consultant and researcher with over 14 years of professional experience. Hernan began his professional career in 1996 with the creation of Virus Sentinel, a signature-based file/memory/mbr/boot sector detection/removal antivirus application with heuristics to detect polymorphic viruses. Hernan also developed a detailed technical virus information database and companion newsletter. He joined Core Security Technologies in 1999 and worked there for 10 years in various roles, including security consultant and exploit writer. As an exploit writer, he performed diverse types of security assessments, developed methodologies, shellcode, and security tools, and contributed new attack vectors. He also designed and developed several low- level/kernel components for a multi-OS security system that was ultimately deployed at a financial institution, and he served as “technical lead” for ongoing development and support of the multi-OS system. Hernan has published a number of security tools, including Universal Hooker (runtime instrumentation using dynamic handling routines written in Python), Pass-The-Hash Toolkit for Windows, and WifiZoo. He is currently working as a security consultant/researcher at Amplia Security, performing network, wireless, and web applications penetration tests; standalone/client-server application black-box assessments; source code audits; reverse engineering; vulnerability analysis; and other information security–related services.
there are several ways to practice this step; the easiest way is to set up a vulner- able target in your penetration-testing lab. once again, using virtual machines is helpful because exploitation can be a very destructive process and resetting a virtual machine is often easier and faster than reimaging a physical machine. if you are new to exploitation, it is important that you have a few immedi- ate successes. this will keep you from getting discouraged as you progress and move onto more difficult targets where the exploitation process becomes more tedious and difficult. As a result it is suggested that you start learning exploi- tation by attacking old, unpatched versions of operating systems and software. successfully exploiting these systems should give you motivation to learn more. there are many examples of students becoming quickly and permanently dis- illusioned with exploitation and hacking because they attempted to attack the latest-greatest-fully-patched operating system and fell flat on their face. remember this book focuses on the basics. once you master the tools and tech- niques discussed here, you will be able to move onto the more advanced topics. if you are new to this process, let yourself win a little and enjoy the experience. if possible, you should try to obtain a legal copy of microsoft’s xP to add to your pen testing lab environment. You should be able to find a legal copy on fIGURE 4.24
It’s pretty difficult to research Web-hosting companies from a standing start — a search at Google.com for “Web hosting” results in almost 400 million hits. The best way to research Web-hosting companies is to ask for recommenda- tions from people who have experience with those companies. People who have used a hosting company can warn you if the service is slow or the com- puters are down often. After you gather a few names of Web-hosting compa- nies from satisfied customers, you can narrow the list to find the one that’s best suited to your purposes and the most cost effective.
This study carried out the Security and defense networks, proprietary research, intellectual property and data based market mechanism that depend on unimpeded and undistorted access call all be severely compromised by malicious intrusions. Researchers proposed data mining for counter terrorism and cyber security application. They concluded Web server logs are mostly captured the behavior of machine, not the behavior of end user, off line analysis of intersection of log files had allowed us to identify some host IP addresses that most probably belongs to intruders. They also concluded that the firewall was set in such a manner that those IP will be banned from accessing our network. Intersection of firewall log files coming from different machines could be a source for IP
Both the experts felt that the security measures taken by banking and companies are not much impactful. “Honestly nothing on internet is safe. Banking verifications and sessions inquiry has been processing but when it is linked with other online website, it can be hacked very easily” opines expert 1. As mentioned earlier, irrespective of safety measures, if an individual is not aware of how to deal with personal information that he/she share in internet or public domains, there is a chance of getting cheated. The experts delineated on the new trending concept called ‘Ethical Hacking’, which has a great scope to address the concerns related to cybercrimes and to have a secured cyber world. The ethical hackers, on behalf of owners or organizations attempts to penetrate a computer system or networks to counter attack the hackers, to find out security vulnerabilities which can be exploited by the hackers. Thus, the experts in the interview insisted on the role of government in initiate proper mechanisms to train and produce more and more ethical hackers for a holistic approach of cyber security.
SQLPrevent: SQLPrevent is yet another tool that uses an HTTP request interceptor. When SQLPrevent is deployed into the web server the original data flow is modified. The HTTP requests are stored in a thread-local storage. The SQL interceptor captures the SQL statements and passes them to the detector module. Thereafter, the HTTP request from the thread local storage is tested for its contents of SQLIA. If the statement is infected it would not be sent to the database. SQLDOM and Safe Query Objects use the concept of query encapsulation that prevent untrusted access to databases. They use a type-checked API which uses systematic query building. Input filtering and strict user type checking is applied in addition to the API. The only reason the approaches fail is because the developer must learn new programming languages. 
Web application has become a very popular application nowadays. Lots of people get connected to the internet regularly in order to fulfill their needs through all sorts of web application. From a provider’s perspective, such applications, as an example e-banking, e-learning, picture and music sharing are easy to manage, and it is easier if only one application on the web is open for access by people around the world than to manage an application installed at specific clients’ computers.
multiple sources, Knowledge/information filtering. Web mining with the owner-centric view allows getting Increasing contact / conversion efficiency (Web marketing), Targeted promotion of services, products, ads; Measuring the effectiveness of site content / structure, Providing dynamic personalized services or content. In the field of Customer analysis, it includes customer profitability, modeling customer behavior and reactions, customer satisfaction etc. Web mining in this field helps us to find strategy that should be used to get number of customers with quality as discussed in . It is used to understand customer behavior, evaluate the effectiveness of a particular Web site, and help quantify the success of a marketing campaign [2, 5].Basically there are three sub categories for mining web information. These sub categories are
Initial Planning: this can be time consuming, but without adequate planning and complete understanding of what the site is for and its intended audience you cannot develop a successful website. Most web designers use a checklist of questions in the initial planning stage. Here is a link to a typical checklist: http://freelanceswitch.com/finding/web-design-client-
An attacker found XSS vulnerabilities in search pages of high profile sites Attacker then used the search functionality to look for popular sites. Attacker then used the search functionality to look for popular search terms (e.g. Paris Hilton), appending the attack vector as part of the search
Summarizing the results of this study, it can be concluded that web-based business model tools do have a future and need to be improved for SMEs business model innovation. Web-based business model tools are supporting SMEs in developing businesses, as they are supporting tools for SMEs to create value, increase in revenues and sustain competitive. However, SMEs lack in knowledge, competences and time for web-based business models. Therefore, based on the study and the application of the theoretical framework, current web-based business model tools need to be optimized, should be simple and user-friendly as possible. Web-based business model tools need to have examples of relevant business models, tutorials, clear guidelines and hints, user- friendly management (throughout the tools) and simple functionalities (e.g., real-time collaboration, automatic saving notes, sharing with colleagues, versioning, editable titles and adding dates). These changes are required by SMEs for web-based business model tools, which make the tools also more fun to play with. Likewise, one of the participants claimed, web-based business model tools need to be used on a daily basis. However, often, SMEs do not have the time for business modelling, as there are focussing on their daily business activities, it may be inconvenient. Therefore I rather disagree with using web-based business model tools on a daily basis, periodically is recommended (e.g., once a month or during new services or products).
The pages and hyperlinks of the World-Wide Web may be viewed as nodes and arcs in a directed graph. The relationship between sites and pages indicated by these hyperlinks gives rise to what is called a Web graph. When it is viewed as a purely mathematical object, each page forms a node in this graph and each hyperlink forms a directed edge from one node to another. Generally user visit a web site in sequential nature means user visit first home page then second page and then third and then finish his work with this user leaves his navigation marks on a server. These navigation marks are called navigation pattern that can be used to decide the next likely web page request based on significantly statistical correlations. If that sequence is occurring very frequently then this sequence indicated most likely traversal pattern. If this pattern occurs sequentially, Markov chains have been used to represent navigation pattern of the web site . Important properties of Markov Chain:
, we can trap the attacker so that recording of the compromise can help in a legal action against the attacker . The technique used in this project is based on average distance estimation in DDoS. We estimate the mean value of the distance in the next time interval by using exponential smoothing estimation technique in this project. This distance based traffic separation DDoS technique uses Minimum Mean Square Error (MMSE) linear predictor to estimate traffic rates from various distances. When the real value is out of the legal scope, the peculiar situation is detected. In the mitigation algorithm, specific detection methods are not involved, but we mainly focus on the resource management aspect of detection. . Filter Tree Approach is used to Protect Cloud Computing against XML DDoS and HTTP DDoS attack, then Sensor Filtering, Hop Count Filter, IP Frequency Divergence, also Double Signature are used to detect HTTPS attacks as discussed in . To separate and protect the web server from huge volumes of DDoS requests when attacked is the main intention behind the proposed system. Particularly, a DDoS defense system for protecting the web services is proposed .

The authors Gerd Stumme, Andreas Hotho have proposed Semantic Web Mining aims at combining the two fast- developing research areas Semantic Web and Web Mining . Web Mining aims at discovering insights about the meaning of Web resources and their usage. Given the primarily syntactical nature of data Web mining operates on, the discovery of meaning is impossible based on these data only. Therefore, formalizations of the semantics of Web resources and navigation behavior are increasingly being used. This fits exactly with the aims of the Semantic Web: the Semantic Web enriches the WWW by machine process able information which supports the user in his tasks. In this paper, from this paper we observed the interplay of the Semantic Web with Web Mining, with a specific focus on usage mining.
