Application Penetration Testing

Safeguard your digital applications by detecting vulnerabilities that could impact the confidentiality, integrity, or availability of your systems and data.

What is Application Penetration Testing?

Application Penetration Testing is a crucial element in the assurance process for digital systems and assets. It ensures compliance with both internal and external standards while minimising vulnerability to cyber threats. This form of testing checks that users can only execute intended actions and that the application has robust measures to safeguard users, particularly in preventing attackers from exploiting a compromised account. The process involves detecting vulnerabilities that might be exploited by attackers, either authenticated or unauthenticated, to:

  • Unauthorisedly access sensitive information.
  • Perform harmful activities within the application.
  • Compromise the security of other users.
  • Increase their access privileges illicitly within the application.
  • Jeopardise the underlying infrastructure of the application.

Appropriate for both internally and externally oriented applications, including web and mobile platforms, Application Penetration Testing aims to identify flaws that could threaten the confidentiality, integrity, or availability of systems and the data they handle.

Why is Application Penetration Testing Essential?

Application Penetration Testing is indispensable for creating a strong security foundation for your applications. It’s crucial for maintaining the health and security of digital systems and applications, which is integral to the continuity of business operations and a key aspect of effective risk management. This ensures the robustness of crucial business services supported by your digital systems and technologies.

For organisations that depend heavily on digital systems and technologies to deliver their business services, regular testing of these digital applications is vital. This is especially true for organisations whose business strategies hinge on leveraging innovative technologies to enhance business performance and success. Ensuring the security of their digital dependencies is paramount.

NeedSec advises that all organisations reliant on constantly evolving digital systems and applications should integrate regular testing into their continuous security assurance program.

Frequently Asked Questions

What information is required to provide a quote/scope a web application penetration test?

The following information, at minimum, is required to scope a web application security test:

 Number of web applications to be tested

 Number of static and dynamic pages

 Number of input fields

 Whether authenticated or only unauthenticated testing is required

How long does it take to perform a web application penetration test?

The duration required for a consultant to conduct a web application penetration test varies based on the test’s scope. The time frame is influenced by several factors, such as the quantity and nature of the web applications being evaluated, the count of static or dynamic pages within these applications, and the number of input fields involved.

How much does a web Application Penetration Test cost?

The price for conducting a web application penetration test is based on the number of days required to complete the specified scope of the project. To obtain a quote, your organisation must fill out a pre-evaluation questionnaire. Experts from NeedSec are on hand to assist you throughout this procedure.

Do you deliver Application Penetration Testing to meet specific compliance requirements?

Testing can be conducted to satisfy various compliance requirements, such as PCI DSS, IT Health Check, ISO 27001, NHS Data Security and Protection Toolkit, Trusted Partner Network (TPN), PCI-DSS and SOC2, among others.

What types of web application penetration testing can be performed?

NeedSec offers testing from both authenticated and unauthenticated viewpoints, representing attackers with varying levels of access and privilege, and simulates a range of threats, including internal and external ones. NeedSec conducts black, white, and grey box assessments to meet diverse client needs.

 Black Box: This testing mimics a real-world attacker with no prior knowledge of the systems in scope.

 Grey Box: Informed by some insights about the application, such as architectural diagrams, documentation, and credentials, this method allows for a more thorough assessment with less time spent on understanding the application’s functionality.

 White Box: Performed with full transparency to the client, this testing includes comprehensive details like source code, architecture, data workflow, etc. It provides an in-depth review of the application to pinpoint deeper security issues from both design and implementation angles.

Where feasible, NeedSec recommends the grey box approach to enhance the value of testing. This method often leads to greater depth and breadth in findings, offering more substantial insights for potential remediations and an overall improvement in security posture.

What industry standards are followed during web application penetration testing?

NeedSec’s Application Penetration Tests are guided by various industry benchmarks, including the OWASP Application Security Verification Standard (ASVS), the OWASP Mobile Application Security Verification Standard (MASVS), the OWASP Web and API Top 10, the Open Source Security Testing Methodology Manual (OSSTMM), and the Penetration Testing Execution Standard (PTES). These standards ensure a comprehensive and up-to-date approach to security testing.

What type of application penetration tests can be performed?

NeedSec can deliver all types of application penetration testing and related assessments, including:

 Internal Application Penetration Testing

 External Application Penetration Testing

 Web Application Penetration Testing

 Mobile Application Penetration Testing

 Cloud-hosted Application Penetration Testing

 Web Application Firewall Penetration Testing

 API Penetration Testing

 Thick Client Penetration Testing



What happens at the end of an application penetration test?

Following each web application security assessment, consultants from NeedSec will compile a detailed written report. This report will outline identified vulnerabilities, their associated risk levels, and suggested corrective measures. Beyond specific remedies, NeedSec aims to offer more comprehensive advice, where feasible, to assist clients in tackling underlying security issues that could be affecting other applications as well.
