How to Make Your Application Security Testing Project Successful


Posted by: Prianka Singla Date: 22 Nov 2023


In today's digitally connected world, application security is most important. Since software and apps are essential to an organization's functioning, protecting the security of these apps should be a primary concern. A robust Application Security Testing (AST) project can help identify and mitigate vulnerabilities before malicious actors exploit them. This blog will explore essential steps to make your Application Security Testing project a resounding success.

Understand the Importance of AST

Before digging into the steps for a successful AST project, it's crucial to understand why it's necessary. AST helps identify vulnerabilities in your applications before malicious actors can exploit them. By identifying and fixing security flaws early, you can save your organization from potential data breaches, financial losses, and damage to your reputation.

Define Clear Objectives

The first step in any successful project is establishing clear and measurable objectives. Determine the goals you have for your application security testing. Are you trying to find weaknesses, evaluate if security standards are being followed, or both? What do you want to achieve with this testing? Is it a new application you are developing or an existing one that needs a security overhaul? Knowing your objectives will help you tailor your testing approach and allocate resources effectively.

Choose the Right Tools and Techniques

For an effective AST, selecting the appropriate tools and techniques is crucial. There are various types of AST methods, including Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Interactive Application Security Testing (IAST). Each has its strengths and weaknesses, so choose the ones that align with your objectives and the nature of your applications.

Dynamic Application Security Testing (DAST) is a method of evaluating the security of a web application while it's running. Here are some common types of DAST assessment:

  1. Web Application Security Assessment - A web application Security Assessment is a thorough and systematic assessment of the security of a web application aimed at identifying vulnerabilities and weaknesses that could be exploited by malicious actors.
    This assessment typically involves a combination of manual and automated testing methodologies. Web Application Security Assessment is generally conducted using OWASP (Open Worldwide Application Security Project) and OSSTMM (Open-Source Security Testing Methodology Manual) methodology.
  2. Mobile Application Security Assessment A mobile web application security assessment is used to conduct thorough security testing, including static and dynamic analysis, to identify vulnerabilities and weaknesses in the app. This assessment typically involves a combination of manual and automated testing methodologies. Mobile Security Assessment is conducted using OWASP MASVS or MASTG.
  3. API security Assessment - APIs play a crucial role in modern web applications by enabling communication and data exchange between different software components.
    API (Application Programming Interface) Security Assessment involves evaluating the security of an application's APIs to identify and remediate vulnerabilities. This assessment typically involves a combination of manual and automated testing methodologies. Mobile Security Assessment is conducted using OWASP API top 10 standard.
  4. Network Security Assessment - A Network VAPT includes a thorough evaluation of the security of a network infrastructure, encompassing systems, devices, and the network architecture itself. The goal is to identify vulnerabilities attackers could exploit and help organizations secure their network environment. Testing is conducted using NIST (National Institute of Standards and Technology) and OSSTMM (Open-Source Security Testing Methodology Manual). There are two types of Network Security Assessments:
    1. External Network Testing: Identify vulnerabilities in the external network infrastructure - test for open ports, misconfigurations, and potential entry points.
    2. Internal Network Testing:
      • Assess the security of internal networks and systems.
      • Test for lateral movement and privilege escalation.
  5. Cloud Security Assessment - Cloud Security Assessment includes assessing the security of cloud infrastructure (e.g., AWS, Azure, GCP), such as test for misconfigurations, insecure storage, and access control issues.

Prioritise Vulnerabilities

Vulnerabilities differ from one another, and each vulnerability has a different impact based on its CVSS score (ranging from 0 to 10, with 10 being the most severe). Once you have identified issues through your AST, prioritise them based on their severity and potential impact. You can reduce the chance of exploitation by focusing on patching the most critical vulnerabilities.

Implement Remediation Strategies

Addressing vulnerabilities is a critical part of a successful AST project. Develop a clear and documented plan for remediation. Encourage collaboration between development and security teams to ensure efficient fixes without disrupting regular development cycles.

Continuous Testing

Application security requires ongoing efforts. It is important to evaluate the effectiveness of your AST program. Incorporate security testing into your software development life cycle. Retest your apps frequently to ensure no new vulnerabilities arise, especially after significant code changes.

Continuously refine your processes to adapt to changing threats and technology.

Provide Training and Awareness

Invest in security training and awareness programs for your development and testing teams. The more they understand security best practices, the less likely vulnerabilities are to be introduced in the first place.

Document and Learn

Ensure your AST project is well documented, including test results, remediation efforts, and lessons learned. Over time, make use of this documentation to enhance your testing procedures.
The field of cybersecurity is constantly changing. Keep up with emerging risks and weaknesses. To keep your apps secure, modify your testing approach appropriately.


Application security is a must when cyberattacks and data breaches are becoming more common and complex. Finding vulnerabilities early on and fixing them is crucial to the success of an application security testing project. You can create a strong AST program that protects your apps and data and ultimately helps your business succeed by setting clear objectives, selecting appropriate assessment methods and tools, and putting in place a continuous testing and improvement cycle.
