Web Application testing

As with network penetration testing, either Black Box, Grey Box or White Box approaches are available for Web Application Testing.

What is Web Application Testing?

Web applications are essential for any business and its day-to-day activities. These applications include programs and websites and as such, they may hold or process sensitive data including logins, user data, and financial information.

Due to the increasing complexity of web applications, cybercriminals are finding more vulnerabilities that can be exploited. It is for this reason that web application testing and security is essential for all businesses.

Web application penetration testing is the authorised security testing of a web application. The purpose of the test is to detect vulnerabilities and identify weaknesses across all aspects of the web application. This includes all of its components such as the back-end network, database, and source code.

Web application penetration testing is similar to standard penetration testing, but it is focused on breaking into the application, by means of a penetration attack. A cybersecurity tester works from the perspective of an attacker to target the web application firewall (WAF). Both manual and automated attacks are simulated using known malicious tactics and techniques.

Highly advised

Do I need a Web Application test?

It is often recommended to have a web application penetration test when your web application is dealing with customer data. A web application test is also advised if the web application is hosted within a server, within the company network, and this is allowing people from the open internet into your company network.

What is required?

The information required to begin a web application test depends upon whether the attack is from the perspective of a black-box test or grey-box test.

Black-box testing – this test is performed by a tester who only has knowledge of the URL and IP address of the web application that requires testing.

Grey-box testing – this test is undertaken with more information than simply the URL and IP address. The tester is given extra information such as to what the application does and what data the application processes.

What our clients think

From my point of view, the most impressive thing about OmniCyber is the feedback I get from others after having introduced them to Omni. An example of those comments include, the best penetration testers I have worked with as they work with you, not just on your system.

Step 1 – Planning and reconnaissance

This stage essentially sets out the scope and the goals of the test, as well as the web application testing methods that will be used. The tester is provided with relevant information about the web applications, such as what the web application does, what the web application is hosted on, who hosts the application, and what type of data is input from the users.

During this stage, comprehensive vulnerability scanning tools will be used, such as Nikto or Burp Suite. These security testing and scanning tools will be used in this stage to identify any potential easy vulnerabilities within the web application.

Stage 2- Exploitation

After the planning and recon stage of the web application, the tester will search for potential exploits and see how the web application responds to intrusion attempts. The intention here is to see if it is possible to take control of the web application or if it is possible to take control of the web server that the application is hosted on.

During the exploitation stage of testing, the tester uses static analysis to look at the source code and assess how it behaves. This is followed by dynamic analysis, where the source code is inspected in real-time, while it is running.

Gaining access to the web application is attempted using a variety of methods including SQL injection, cross-site scripting, traffic interception, and backdoor access.

Stage 3 – Post exploitation

Once access has been gained to the web application or web server, the server will be used as a pivot point to see how far the tester can get into the company network. At this stage, the tester may attempt to raise privileges, intercept traffic, and steal data, to gain an understanding of the level of damage that can be done.

Stage 4 – Analysis and feedback

The analysis of the penetration testing will provide the client with an in-depth report detailing its findings.

The feedback will help the company and its security personnel to patch and repair any of the vulnerabilities that have been identified. The web application firewall may be reconfigured to protect the company against future cyber attacks.

The report can further provide value be identifying and prioritising which weaknesses and vulnerabilities should be tackled first. The report will outline what action needs to be taken to address the identified risks.
