Case Study: How Can a Leading Tire Manufacturer Strengthen Web Application Security to Protect Sensitive Customer Data?

Mobile Testing Client Profile

The client is a leading tire manufacturer that focuses on developing and manufacturing a diverse portfolio of tires, delivering social and customer value. As an industry leader in transportation, the client has a large fleet of software deployed for various operations. They excel at offering best-in-class offerings to consumers around the world.

Mobile Testing The Hurdle

Web application security testing is critical to ensuring the security and reliability of web-based applications. As a large company, the customer possesses an extensive database of sensitive data, including customer data and PII information, which is an appealing target for hackers. To ensure that the existing security measures are effective enough to protect all the assets from unauthorized access, the customer decided to evaluate the level of security to eliminate any existing security issues.

Mobile Testing Our Approach

An expert team of security testing specialists was assigned to this project. All the sensitive areas were included in the scope, and the team followed a four-step process:

  • Reconnaissance

    The team started by gathering information about the application and its environment. This includes identifying web server type, application framework, database, and API.

  • Vulnerability Scanning

    This step utilized a combination of tools to perform various security scans and identify vulnerabilities in the application.

  • Exploitation

    Security engineers attempted to exploit any vulnerabilities identified in the previous steps. This involved attempts to gain unauthorized access to the application or its underlying systems or to escalate privileges.

  • Reporting

    Finally, the team documented all the identified vulnerabilities and provided recommendations for remediation. The report includes a description of the vulnerabilities, their potential impact, and a recommendation for mitigating them.

Mobile Testing The Transformation

The penetration testing identified several vulnerabilities in the application, including:

  • SQL Injection Vulnerability

    The application was found to be vulnerable to SQL injection attacks, which could allow an attacker to access the database and steal sensitive information.

  • Cross-site Scripting (XSS) Vulnerability
    The application was also found to be vulnerable to XSS attacks, which could allow an attacker to execute malicious code in the user's browser.

  • DoS (denial-of-service)
    Testers were able to send thousands of requests from a single source, which caused the application to be unavailable for some time, resulting in financial losses and reputational damage.

  • Unauthorized Access to the Application
    The application was also found to be vulnerable to unauthorized access, which can result in security breaches, data leaks, unauthorized modifications, and other malicious activities that can compromise its confidentiality.

Based on the results of the penetration testing, the following recommendations were made to the client:

  • Implement input validation to prevent SQL injection attacks.
  • Implement measures to prevent XSS attacks, such as input filtering and output encoding.
  • Implement a more robust password policy that requires users to choose complex passwords and enforces password expiration policies.

The penetration testing successfully identified several vulnerabilities in the web application. By addressing these vulnerabilities, we improved the application's security and protected sensitive information.

Frequently Asked Questions

What are Application Security Testing Services, and why are they necessary?

Application security testing services are specialized assessments designed to identify and address vulnerabilities within software applications. These services combine manual expertise with automated tools to evaluate the security of an application’s code, configurations, integrations, and runtime behavior. They are essential because applications are a primary target for attackers, often holding sensitive business and customer data that, if compromised, can lead to financial loss, reputational damage, and regulatory penalties. By detecting and remediating vulnerabilities early, AST helps organizations reduce risk, ensure compliance with security standards and regulations, and strengthen overall resilience against evolving threats.

What is Automated and AI-augmented Application Security Testing?

Automated and AI-augmented Application Security Testing refers to the use of advanced automation and artificial intelligence techniques to enhance traditional security testing practices. Automated testing streamlines repetitive tasks such as vulnerability scanning, test case execution, and regression checks, ensuring faster and more consistent coverage. AI augmentation takes this a step further by applying machine learning and intelligent algorithms to prioritize high-risk areas, generate realistic test data, detect hidden patterns, and recommend the most effective tools and techniques.

Together, these approaches accelerate security assessments, reduce human error, and enable organizations to scale testing across complex applications and frequent release cycles. By combining speed, accuracy, and intelligent insights, automated and AI-augmented application security testing helps uncover vulnerabilities more efficiently while strengthening overall application security posture.
