Applicative Penetration Testing

An application penetration test, also known as an applicative penetration test or application
security testing, focuses on assessing the security of software applications, including web
applications, mobile apps, desktop software, and APIs. The goal is to identify vulnerabilities
within the application's code, logic, and architecture that could potentially be exploited by
attackers. Here's a step-by-step guide to conducting an application penetration test:

**1. Define Objectives and Scope:**
– Determine the goals of the test, such as identifying vulnerabilities in a specific application,
API, or software component.
– Clearly define the scope of the test, including the application's features, functionality, and
supported platforms.

**2. Pre-Engagement Activities:**
– Obtain proper authorization from the organization to conduct the penetration test.
– Gather information about the application, its architecture, and the technologies used.

**3. Information Gathering:**
– Collect details about the application's URL, endpoints, user roles, and authentication
– Understand the application's functionality and business logic.

**4. Threat Modeling and Risk Assessment:**
– Identify potential threat vectors and attack scenarios specific to the application.
– Assess the potential impact and likelihood of different types of attacks.

**5. Vulnerability Assessment:**
– Use automated scanning tools to identify common vulnerabilities, such as SQL injection,
cross-site scripting (XSS), and security misconfigurations.
– Manual code review to identify complex vulnerabilities and logic flaws.

**6. Authentication and Authorization Testing:**
– Test the application's authentication mechanisms for weaknesses or vulnerabilities.

– Check if authorization controls are properly enforced for different user roles.

**7. Input Validation and Output Encoding:**
– Test input validation mechanisms to identify data validation vulnerabilities.
– Ensure the application properly encodes output to prevent XSS attacks.

**8. Session Management and Cookies:**
– Evaluate how the application manages sessions and cookies to prevent session-related
– Test for session fixation and session hijacking vulnerabilities.

**9. Business Logic Testing:**
– Analyze the application's business logic to identify potential vulnerabilities and logic flaws.
– Test for scenarios where attackers might manipulate the application's behavior.

**10. API Security Testing (if applicable):**
– Test the security of APIs for vulnerabilities such as insecure API endpoints, insufficient access
controls, and input validation issues.

**11. Exploitation and Post-Exploitation:**
– Attempt to exploit identified vulnerabilities to assess the potential impact and gain
unauthorized access.
– Explore post-exploitation scenarios to determine the extent of compromise.

**12. Reporting:**
– Document all findings, including vulnerabilities, exploited weaknesses, and potential risks.
– Provide a detailed report outlining the impact of each vulnerability and recommended
remediation steps.

**13. Remediation and Recommendations:**

– Collaborate with the development team to prioritize and address identified vulnerabilities
and weaknesses.
– Provide guidance on best practices for securing application code and design.

**14. Retesting:**
– Conduct a retest to ensure that identified vulnerabilities have been properly remediated.

**15. Continuous Improvement:**
– Implement the recommended security improvements and continuously monitor and assess
application security.

Application penetration testing requires a solid understanding of application development,
security vulnerabilities, and programming languages. It's important to follow ethical guidelines,
obtain proper authorization, and work closely with the development team to ensure a
successful and impactful testing process.
