Penetration testing for web applications is performed on servers that have internet connectivity. It is a comprehensive test procedure that checks the inner workings of a web application. This is used to determine whether information is safe and secure from outside threats.
Penetration testing for web applications can only be performed in two manners: either by simulating an external or an internal attack. This enables the identification of any security vulnerabilities that might exist in the corporate firewall. Some of the common internal attacks that can occur include: Malicious Employees Attacks, by employees, contractors or others who have left the company but still have access to your network. Networking Insecurity
One of the main objectives of pen testing is to find out if your application is vulnerable to external attacks. The results of a penetration testing are often quite alarming because they reveal a lot about the inner workings of your web applications. Penetration testing can also identify weak spots in your network infrastructure. While most companies try to cover their backdoors with various techniques, sometimes these techniques are too obvious to ignore. A skilled tester can help you detect these attacks easily.
The primary objective of this kind of testing is to discover if there is a web services vulnerability that can allow a hacker to access your data or system. Most testers use a range of methods to achieve this goal. Some testers use automated scanning devices while some use manual testing. However, the automated scanners and manual testers depend upon different parameters for successful testing. Therefore, it is important to follow the guidelines set forth by the testers for successful testing.
Testing Web Applications
The first testing method used is vulnerability assessment, which is sometimes referred to as pen test or stage one testing. This is performed by manually submitting fake user inputs or commands to the application in order to determine whether these inputs trigger an open or closed vulnerability. The severity of a vulnerability determines the level of testing required to solve the problem. For instance, a user may only be able to access a web services application in certain conditions or under certain conditions.
Another method used for detecting vulnerabilities is cross-site scripting (XSS) testing. In this method, testers find out whether web application script files are allowed to access the target site. The scripts are created with the help of scripts programming language (SPS) tools and are sent through error messages, mail servers and other web applications. The testing team validates the scripts used by the hackers by determining if they trigger an open or closed vulnerability. Sometimes, web testers use web-based database applications or stored procedures that access the target server to determine whether the application is vulnerable to attack or not.
During the process of testing, testers use various techniques to check the performance of the application. They perform speed, memory access and other processes to make sure that all components are executing appropriately. They also check for security vulnerabilities by creating fake log files and performing other activities such as changing password. When the security issue has been discovered, testers create corresponding patches and install them on the system. Once the application has been patched, tester continues to monitor and test its performance.
Penetration testing is also used to determine whether web applications are able to access and use sensitive data. Testing techniques include code injection, code overwriting, buffer overflow and others. These techniques allow attackers to send specially crafted codes to execute malicious code. Testers simulate network attacks and check whether the application is vulnerable to these attacks. In some cases, testers use network testing methods together with vulnerability assessment to find whether a particular program contains vulnerabilities. With proper management and administration, the risk of web application security can be controlled to a great extent.
