Types of Penetration Testing For Web Applications can be performed in two manners: either by simulated an on-line attack or by performing an on-line attack internally. This facilitates the detection of any vulnerabilities that may exist inside the internal corporate firewall. On-line testing refers to the procedure adopted to test the website against known attacks and their results. The purpose of this is to find out whether the application is returning all the correct results.
Penetration Testing of web applications could be performed both on-line and offline. On-line testing involves the use of fake internet connections in order to execute the web applications under attack. The attacker is provided with a website which is perfectly configured to carry out the attacks. The web applications are loaded to the system and when this process is completed successfully, the web browser will allow the user to view all the files located on the targeted server. In case of on-line pen testing, these attacks occur with an effort to get the most out of the testing environment.
Pen testing of web services enables organizations to discover vulnerabilities present in the web services and to make the necessary changes to the application as and when required. The pen testing process starts with the generation of executable files. After creating these executable files, the tester uses the command line and passes it to the browser in order to execute the selected web services. In cases where no executable files are present, a fake server is used in order to generate the code execution. When the browser processes the generated code, it comes across various issues which will then cause the application to crash and display an error message.
Testing Web Applications
For web applications, the process of pen testing is often carried out after the website has been launched. When the website is launched, the most common factor for the attack to occur is a cross-site vulnerability. It is due to this reason that organizations conduct regular network scanning in order to detect any such vulnerability. With this, regular scanning of the network can help to prevent such attacks from taking place. This also helps them to roll out the appropriate fixes to stop the attacks once they have taken place.
In addition to performing manual penetration testing of web applications, automated tools for the same purpose are also available nowadays. These automated tools work just like a manual scanner. The only difference between the two is that a manual scanner is programmed to search for vulnerabilities, whereas the automated tools are designed to perform the scanning irrespective of whether there is any vulnerability present or not. The tool used for manual penetration testing is mostly a browser like Internet Explorer or Firefox. However, with the advent of automated tools, all businesses today can carry out the testing of web applications themselves.
Another way in which organizations automate the testing process is by using Scrum, a project management approach. With this approach, every team involved in web application testing starts working from a master strategy. Project managers and developers use this strategy to ensure that they cover all the important areas. They ensure that the testing is performed within the time frame specified, as well as continuously monitor the progress of the testers.
