Web application penetration tests use software to scan and attack internet-based programs. They identify vulnerabilities and suggest fixes before software release to avoid compromising attacks. Tests use URL manipulation, session hijacking, SQL injection, and buffer overflow.
A web application penetration test is an activity designed to measure the behavior of an Internet-based program during an attack or exploit. These tests use a variety of software programs to scan an application and then perform various actions that could occur during an actual attack. A web application penetration test can be performed by a development team or a third-party service provider. If an external vendor is used, the development team or information technology (IT) staff will sometimes not be notified of the test by management. This could allow a penetration test of the web application to uncover flaws that would otherwise have gone unnoticed, which can allow such problems to be fixed before the software is released.
Web applications are software packages that can be accessed and run over the Internet. These applications can perform many functions and in some cases are responsible for handling data that is considered private or even valuable. In order to avoid compromising attacks, penetration tests are usually performed to find any weaknesses or easily exploitable areas in the code.
Typical web application penetration testing begins with an information gathering phase. The purpose of this step is to determine as much information about the application as possible. By submitting requests to the application and using tools such as scanners and search engines, information such as software version numbers and error messages can often be obtained which is often used to find exploits later.
Once enough information has been accumulated, the next goal of a web application penetration test is to perform a variety of different attacks and exploits. In some cases, the information gathered during the first stage will identify exploits to which the application may be vulnerable. If no obvious vulnerabilities have been found, a full range of attacks and exploits can be attempted.
Many different technical vulnerabilities can be discovered by a web application penetration test. These tests typically attempt to use methods such as Universal Resource Locator (URL) manipulation, session hijacking, and Structured Query Language (SQL) injection. ) to enter an application. There may also be an attempt to initiate a buffer overflow or other similar action that can cause an application to misbehave. If any of these attacks or exploits cause the application to reveal sensitive data to the penetration tester, the flaws are typically reported along with a suggested course of action.
