Web Application Security Testing

Assess your web application for security vulnerabilities with a comprehensive security test

Web Application Security Testing

Penetration testing, or “pen testing,” is a simulated cyber attack that is conducted on computer systems, networks, and web applications. It’s also commonly referred to as “ethical hacking.” The goal of pen testing is to identify vulnerabilities and security weaknesses that could be exploited by malicious actors. To do this, pen testers use manual and automated techniques to try and compromise servers, endpoints, web applications, wireless networks, network devices, mobile devices, and other potential points of exposure.

As web technologies have progressed in recent years, so have the security risks associated with them. Many companies rely heavily on web applications to store and process business-critical data, both internally and publicly. It’s more important now than ever to ensure that these applications are properly secured against potential cyber threats. And one of the best ways to do this is through web application penetration testing.

Web Testing Methodology – What do we test for?

  • The OWASP framework acts as a guide as we test all critical areas of a web application security testing.

  • Web applications are among the most rapidly evolving and diverse technologies in use today. 

  • As a result, we use our own specialized tools and methodologies to adapt to this ever-changing environment.

  • This thorough approach guarantees that our clients receive the best service possible.

  • We perform web application security testing based on OWASP Framework checklists.

  • Information Gathering
  • Configuration and Deploy Management Testing
  • Identity Management Testing
  • Authentication Testing
  • Authorization Testing
  • Session Management Testing
  • Data Validation Testing
  • Error Handling
  • Cryptography
  • Business logic Testing
  • Client Side Testing
  • API Testing

We collaborate closely with our clients to ensure the best possible outcome for all engagements. Protect your assets and improve your security posture with Cyber Legion.


Web application penetration testing is the practice of detecting vulnerabilities in a web application using penetration testing methodologies. A good web application penetration test will be conducted to the OWASP standard of web application testing.

The OWASP methodology includes but is not limited to:

Authentication testing: Testing the authentication mechanisms of the web application, this includes attacks such as brute-force, username enumeration and SQL authentication bypass techniques. A07:2021-Identification and Authentication Failures
Access Control Testing: Often known as authorisation testing, is the process by which a web application provides some users access to material and capabilities while denying access to others. OWASP – A01:2021-Broken Access Control
Injection: Generally the application will suffer from injection vulnerabilities of the data is not sanitized or validated by the web application. Cross-site scripting, SQL injection, OS command injection are just some common injection techniques. A03:2021-Injection
Security Misconfigurations: Verbose stack trace errors, clickjacking, default accounts and missing HTTP Security Headers are just a few of the common security misconfigurations found on modern web applications. A05:2021-Security Misconfiguration
More information on the OWASP Top 10 can be found here: OWASP Top 10 2021.

The OWASP Security Knowledge Framework is an open source web application that explains secure coding principles in multiple programming languages. The goal of OWASP-SKF is to help you learn and integrate security by design in your software development and build applications that are secure by design.

Web applications are often extremely important to a business’s functionality and can collect huge amounts of data about customers or the business its self. These can be public applications or internal applications and each come with its own set of risks. Due to the importance of these applications, they must be protected from their data being stolen.

As a result, protecting these applications is an arms race, and the ability to find what developers have missed due to deadlines or oversight is crucial. Website security testing helps eliminate the risks associated with building modern web applications.

Penetration tests (or pen tests) are attacks on your companies’ software and hardware systems, carried out by ‘ethical hackers’ to expose your system’s vulnerabilities. One example is a web application pen test. Web apps, browsers and plug-ins can house sensitive financial or personal data, so hackers are increasingly putting their efforts towards gaining access to them. The test would examine the endpoint of every web application.

The time that penetration testing takes depends on the size and complexity of your organization’s system structure, as well as the scope of the test itself. For the ‘average’ company, a network penetration test should take around three days. For a merchant processing millions of credit cards a year, for example, a pen test will take over a week, or possibly two.

The penetration testing cost depends on the facts identified during scoping, such as the agreed time, goals, technical resources, approach, and remedial support.

This is a weakness in the web application. The cause of such “weakness” can be due to the bugs in the application, an injection (SQL/ script code) or the presence of viruses.

Some web applications communicate additional information between the client (browser) and the server in the URL. Changing some information in the URL may sometimes lead to unintended behaviour by the server and this is termed as URL Manipulation.

This is the process of inserting SQL statements through the web application user interface into some query that is then executed by the server.

When a user inserts HTML/ client-side script in the user interface of a web application, this insertion is visible to other users and it is termed as XSS.

Remote code execution (RCE) attacks allow an attacker to remotely execute malicious code on a computer. The impact of an RCE vulnerability can range from malware execution to an attacker gaining full control over a compromised machine.
