Web Application Penetration Testing
Web application security testing involves simulating a real-world attack on your web application to detect and analyze potential security vulnerabilities that could be exploited by attackers. Given the critical role web applications play in business operations, they are a prime target for cybercriminals. This testing process proactively identifies vulnerabilities that could lead to the compromise of sensitive user and financial information, helping to safeguard your application against threats.
Methodology
Our comprehensive penetration testing approach goes beyond identifying security vulnerabilities to also uncover business logic flaws. We adhere to industry-standard security checklists, including OWASP Top 10, SANS 25, and OSSTMM. With extensive experience across various application threat surfaces—whether online, mobile, or cloud. Staatse Security offers both on-premises and off-premises application security services, following a proven roadmap to ensure robust protection.
Black Box
Black Box, often referred to as behavioral testing or external testing, is a form of software testing technique wherein no prior knowledge of the internal code structure, implementation specifics, or internal routes of an application is necessary. It focuses on the application’s input and output and is entirely dependent on the specifications and requirements for the software.
Gray Box
Gray Box Testing is a software testing approach that combines elements of both Black Box and White Box testing. It involves testing an application with a general understanding of its internal code structure. This method is particularly effective in identifying context-specific errors that may arise from flaws in the application’s code architecture.
White Box
White Box Testing involves examining a software application’s internal structure, code, and architecture to validate input-output flows and enhance the design, security, and functionality of the application. This method is also known as internal testing, clear box testing, open box testing, or glass box testing, as it allows testers full visibility of the code.

Security Testing Methodology
Reconnaissance
Reconnaissance, or information gathering, is a critical initial phase in application penetration testing. This stage involves collecting as much information as possible about the target application. Examples of reconnaissance activities include Search Engine Reconnaissance, App Enumeration, and App Fingerprinting to identify the application’s entry points and potential information leaks.
Configuration Management
Understanding the configuration of the server or infrastructure hosting the web application is essential. Key issues include insecure HTTP methods, outdated backup files, and TLS security. Configuration management checks encompass TLS Security, App Platform Configuration, File Extension Handling, and HTTP Transport Security to ensure the application’s security posture is robust.
Authentication Testing
Authentication testing involves validating the mechanisms used to confirm the identity of users. This includes evaluating the login process and its vulnerabilities. Examples of authentication testing include assessing lockout mechanisms, bypassing authentication schemas, and analyzing weaknesses in browser cache and alternative channels.
Session Management
Session management involves controlling the interaction state between users and the web application. This includes managing user authentication, session fixation, Cross-Site Request Forgery (CSRF), cookie management, session timeout, and logout functionality to ensure secure session handling.
Authorization Testing
Authorization testing verifies that users with authenticated credentials are granted appropriate roles and privileges. This phase includes testing for directory traversal, privilege escalation, bypassing authorization controls, and insecure direct object references to confirm that authorization mechanisms are correctly enforced
Data Input Validation
Data input validation is crucial for preventing common security flaws. This involves testing for vulnerabilities such as Cross-Site Scripting (XSS), SQL Injection, OS Commanding, and Buffer Overflow, which can occur when inputs are not properly validated.
Testing for Error Handling
Effective error handling testing involves analyzing error codes and stack traces generated by the application. These errors can reveal valuable information about the application’s inner workings and potential vulnerabilities, including issues with databases and other components.
Testing for Business Logic
Business logic testing focuses on vulnerabilities that are application-specific and not typically detected by automated scanners. These issues often require creative and expert testing approaches. Examples include integrity checks, process timing, unexpected file uploads, and request forgery.
Client-Side Testing
Client-side testing examines the execution of code in the client’s environment, such as within a web browser or plugin. This includes testing JavaScript execution, client-side URL redirection, Cross-Origin Resource Sharing (CORS), and manipulation to identify potential vulnerabilities.
Denial of Service (Optional)
Denial of Service (DoS) testing aims to assess the application’s resilience to attacks that disrupt service availability. This phase focuses on application-layer attacks that a single user can execute, distinguishing it from traditional network-based DoS attacks.
Reporting
The reporting phase involves compiling, ranking, and prioritizing findings to produce a clear, actionable report with supporting evidence. This phase is crucial for communicating the value of the testing process and its findings to stakeholders.

Still have unanswered questions and need to get in touch?
What are the benefits of regular web application security testing?
Regular web application security testing helps identify vulnerabilities before they can be exploited by attackers, ensures compliance with security standards, and maintains the integrity and confidentiality of sensitive information. It also aids in improving the overall security posture of the application.
What is the duration of performing VAPT (Vulnerability Assessment and Penetration Testing)?
The duration of VAPT depends on the scope of testing and the complexity of the network and applications being assessed. Factors such as the size of the application, the number of systems, and the depth of the assessment influence the overall timeline.
What are the common aspects to test during security testing?
Security testing typically involves assessing various aspects of an application, including Confidentiality, Integrity, Authentication, and Availability. These elements are critical for identifying system flaws and ensuring the application’s overall security posture.
What is web application scanning?
Web application scanning involves using automated tools to search for security flaws in web applications. The scanner crawls the entire website, examining each file and mapping the website’s structure to identify potential vulnerabilities.
What tools are commonly used for web application security testing?
Common tools for web application security testing include automated scanners such as OWASP ZAP, Burp Suite, and Acunetix, as well as manual testing tools and techniques. These tools help identify and assess vulnerabilities in web applications.
How does web application security testing differ from network security testing?
Web application security testing focuses on identifying vulnerabilities specific to web applications, such as input validation issues and authentication flaws. Network security testing, on the other hand, examines the overall network infrastructure for weaknesses that could be exploited to gain unauthorized access or disrupt services.
How often should we conduct web application security testing?
Web application security testing should be performed regularly to address emerging threats and vulnerabilities. Frequent testing helps maintain consistent IT and network security management by identifying and mitigating potential risks before they can be exploited by attackers.
What does effective security rely on?
Effective security relies on several key fundamentals, including the ability to identify and assess threats, correlate data across systems, and enforce security regulations within a dynamic and distributed network environment.
