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.

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 information is required to start a web application test?

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.

How web application penetration testing works

Web application penetration testing is most often performed in four stages. This four-stage process includes the following elements: Planning and reconnaissance - Stage 1 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. Exploitation - Stage 2 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. Post exploitation - Stage 3 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. Analysis and feedback - Stage 4 The analysis of the penetration testing will provide the client with an in-depth report detailing its findings. The analysis report will include: What sensitive and confidential information and data was accessed Which critical vulnerabilities were identified and exploited The length of time that the web application tester was able to stay in the system without detection. 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.

No, OmniCyber Security uses the reconnaissance and exploitation process described above to give post exploitation feedback.

Yes, OmniCyber Security uses Nikto, an open source web server scanner that runs in-depth tests against web servers and web applications. Our CREST Certified hackers also use the most common web application testing tools, which are part of the Burp Suite of scanning and security testing tool portfolio. Kali Linux is another advanced penetration testing tool that we use to make network security assessments through ethical hacking practices.

Internal testing works on the premise where the tester has insider access, such as that of an employee of the company. This scenario simulates what might happen if an employee takes malicious action against the company or what might happen if a hacker has acquired employee credentials through a phishing attack.

External web application penetration testing is conducted from the outside, through web apps that are visible on the internet.

Blind testing is conducted with only the knowledge of the company name and web application. This form of cyber-security testing replicates exactly how a real cyber attack takes place.

Double-blind testing takes place without the security and IT personnel of the company having prior knowledge of the simulated cyber attack.

Targeted testing is often used as a training exercise for the security personnel of the company. The tester and security personnel keep each other informed of the steps being taken so that the security personnel can understand in real-time the actions taken by the ethical hacker.

Mobile web application testing focuses on identifying the security vulnerabilities of mobile apps.
