DAST and MAST
What is DAST?

Dynamic Application Security Testing (DAST) is a method of evaluating the security of web applications while they are running. Unlike static analysis, which examines the source code of an application without executing it, DAST interacts with the application dynamically, emulating real-world attacks to identify vulnerabilities. Here’s an overview of what DAST is and why it’s important for ensuring the security of web applications:
1. Dynamic Testing:
DAST tools interact with web applications in the same way as an attacker would, sending various requests and inputs to the application and analyzing itsresponses. This dynamic approach allows DAST to uncover vulnerabilities that may not be apparent through static analysis alone.
2. Real-world Simulation:
By simulating real-world attack scenarios, DAST provides a more accurate assessment of an application’s security posture. It helps identify vulnerabilities such as SQL injection, cross-site scripting (XSS), authentication flaws, and other common security
issues that could be exploited by malicious actors.
3. Comprehensive Coverage:
DAST examines the application as a whole, including its frontend interfaces, backend components, APIs, and server-side functionalities. This comprehensive coverage ensures that vulnerabilities in any part of the application arecidentified, regardless of whether they stem from coding errors, misconfigurations, or other factors.
4. Detection of Runtime Vulnerabilities:
Since DAST tests applications while they are running, it can detect vulnerabilities that only manifest during runtime, such as those resulting from input validation failures, session management issues, or insecure server configurations.
5. Scalability and Automation:
DAST tools can be automated to conduct scans regularly, making them well-suited for large-scale or frequently updated applications. This scalability enables organizations to assess the security of their web applications continuously and efficiently, even as they evolve over time.
6. Integration into SDLC:
DAST can be integrated into the Software Development Life Cycle (SDLC) at various stages, including development, testing, and production. By incorporating security testing into the development process, organizations can identify and address vulnerabilities early, reducing the risk of security incidents in production environments.
7. Compliance and Risk Management:
DAST helps organizations meet regulatory requirements and industry standards by identifying security vulnerabilities that could expose sensitive data or compromise the integrity of their systems. It also aids in risk management efforts by providing insights into the potential impact of vulnerabilities and guiding prioritisation of remediation efforts.
In summary, DAST plays a crucial role in ensuring the security of web applications by dynamically testing them for vulnerabilities, simulating real-world attack scenarios, providing comprehensive coverage, detecting runtime issues, enabling scalability and automation, integrating into the SDLC, and supporting compliance and risk management initiatives.
DAST (Dynamic Application Security Testing) Scan Process

The term “DAST scan” stands for Dynamic Application Security Testing. It’s a process used to detect and assess security vulnerabilities in web applications while they are running. Here’s a basic outline of the DAST scan process:
1. Preparation:
- Define the scope of the scan, including which web applications will be tested and whichfunctionalities will be covered.
- Gather necessary information about the applications, such as URLs, authentication mechanisms, and any specific configurations.
- Configure the DAST tool with the appropriate settings for the scan, such as authentication credentials and scan parameters.
2. Scanning:
- The DAST tool simulates attacks against the target web application, exploring various paths and inputs to identify potential vulnerabilities.
- Common techniques used during scanning include fuzzing input fields, injecting malicious payloads, and analyzing responses for anomalies.
- The tool typically generates a report detailing the findings, including the severity of vulnerabilities and their potential impact.
3. Analysis:
- Security professionals analyze the results of the scan to prioritize and validate the identified vulnerabilities.
- They assess the impact of each vulnerability on the application’s security and determine the appropriate remediation steps.
4. Remediation:
- Developers and administrators address the identified vulnerabilities by implementing fixes or mitigations.
- This may involve patching code, updating libraries, reconfiguring the application, or deploying additional security controls.
5. Re-Scan (Optional):
- After remediation, it’s often advisable to conduct another DAST scan to ensure that the vulnerabilities have been effectively addressed.
- This step helps verify that the security posture of the application has improved and that no new vulnerabilities have been introduced.
6. Documentation and Reporting:
- Document the findings, remediation actions taken, and any residual risks that may still exist.
- Generate a final report summarizing the results of the DAST scan, including details on vulnerabilities, their severity, and recommended actions.
7. Continuous Monitoring:
- DAST scanning is often part of a larger security strategy that includes continuous monitoring and testing.
- Regularly scheduled scans help maintain the security of web applications by identifying new vulnerabilities or regressions introduced during development or changes in the application’s environment.
By following these steps, organizations can improve the security posture of their web applications and mitigate the risk of security breaches and data leaks.
What is MAST?

Mobile Application Security Testing (MAST) refers to the process of evaluating the security of mobile applications to identify and mitigate potential vulnerabilities and threats. It involves various techniques and methodologies aimed at uncovering security weaknesses that could be exploited by attackers to compromise the confidentiality, integrity, or availability of mobile apps and their associated data. Here’s an overview of what Mobile Application Security Testing is and why it’s crucial for ensuring the security of mobile applications:
1. Identification of Vulnerabilities:
MAST helps identify security vulnerabilities and weaknesses in mobile applications, including issues such as insecure data storage, insufficient authentication mechanisms, improper session management, input validation flaws, insecure communication channels, and other common security pitfalls.
2. Prevention of Exploitation:
By identifying vulnerabilities before malicious actors do, MAST enables organizations to proactively address security risks and prevent exploitation. This reduces the likelihood of security breaches, data leaks, financial losses, and reputational damage associated with compromised mobile applications.
3. Protection of User Data:
Mobile applications often handle sensitive user data, including personal information, financial details, and authentication credentials. MAST ensures that proper security controls are in place to protect this data from unauthorized access, disclosure, or manipulation.
4. Compliance with Regulations:
Many jurisdictions have regulations and compliance standards governing the protection of user data and privacy, such as GDPR (General Data Protection Regulation) in Europe and CCPA (California Consumer Privacy Act) in the United States. MAST helps ensure that mobile applications comply with these requirements, avoiding potential legal repercussions and financial penalties.
5. Enhancement of User Trust:
Security breaches can erode user trust and confidence in mobile applications and their developers. By conducting thorough security testing and addressing vulnerabilities promptly, organizations demonstrate their commitment to protecting user privacy and security, thereby enhancing trust and loyalty among their user base.
6. Support for Secure Development Practices:
MAST promotes a security-conscious mindset among mobile application developers and stakeholders. By integrating security testing into the software development lifecycle, organizations can identify and address security issues early in the development process, reducing the risk of vulnerabilities making their way into production environments.
7. Risk Management:
MAST helps organizations identify and prioritize security risks associated with mobile applications, allowing them to allocate resources effectively to mitigate the most critical vulnerabilities. This risk-based approach enables informed decision-making and investment in security controls commensurate with the level of risk.
In summary, Mobile Application Security Testing (MAST) is essential for ensuring the security of mobile applications by identifying and mitigating vulnerabilities, protecting user data, complying with regulations, enhancing user trust, promoting secure development practices,
