What is Application Penetration Testing?

It is assessing a web application for security weaknesses. An application could be a retail or banking site. The aim of the test is to identify any security issues that can be misused by hackers. A tester will perform a thorough review of the entire site to find errors and recommend fixes.

Criminals target applications that provide access to valuable data such as credit card or personal details. A company often performs testing to allay security concerns for any current and future customers.


Is Application Penetration Testing Right For You?

A company performing a test can be:

Checking that a new web application has no major security issues.

Testing networks and assets for compliance. Ensuring that they avoid fines or penalties.

Needing an independent review of their products for their clients.

Demonstrating that they have fixed problems that previously resulted in a security breach.

Ambersail Application Penetration Testing Methodology


Our test team starts by studying an application to see how it is built. They will identify any web servers, databases and firewalls.  This helps to create a blueprint for the next stage.


We now understand the structure of the web application. Our test team can then review how the application works and what business functions it supports. We map how users are managed, what data is stored  and how it is protected.


Our attention now turns to finding areas of weakness. Often, simple manual tests carried out by capturing and changing web traffic reveals a wealth of useful information. Our testers use this knowledge to construct exploits.

Testing can find failures in how users sign-in, or what sensitive data is available. Is data entered by users processed in a safe manner? Our testers are constantly looking for information that is useful to an attacker.

Why Perform Application Penetration Testing?

To find out how secure web applications are. Testing is very important for sites that process sensitive data such as financial or personal data.

As the cost to business through cyber attack continues to grow, removing weakness from applications becomes more important. As a result, compliance and standards bodies expect application penetration testing.

Companies should view testing as a business requirement.

Is Application Penetration Testing Important?

Many companies rely on web applications to support vital business functions.

Consider a company with a web application used to sell products to its clients. It monitors the security of its network using an Intrusion Detection System. This reviews all network traffic and stops attacks such as denial of service.

Anyone accessing the web application communicates using trusted channels. This means that a person using the web application has valid access. As a result, security monitoring will not see a problem.

At this point, most users will use the application as intended. A hacker, however, would try to get the application to behave differently. Their aim is to find any weakness in how it was built. To access any stored data.

Always Check Data

Companies perform Application Penetration Testing  to understand how an application deals with data entered by the user.  This is known as Input Validation and if companies do not check correctly, it can create real problems.

Why is this important? If an application cannot filter input from users, it can behave in unpredictable ways. When this happens, a hacker could gain control of the application.

Testing also identifies other problems such as weak passwords and issues with access controls. We suggest using OWASP  as a guide for security.

Finally, remember that criminals and hackers spend time to break down networks. For this reason, companies  should adopt the same approach when testing. Make sure experienced testers perform the test and do not rely on automated tests.
