Dynamic Application Security Testing (DAST)

Dynamic Application Security Testing (DAST) is a security testing methodology that analyzes a running application to identify vulnerabilities and security flaws. Unlike Static Application Security Testing (SAST), which examines source code, DAST focuses on the application while it is executing, simulating attacks to discover potential vulnerabilities that could be exploited.

Key concepts in DAST include:

• **Black-box Testing**: DAST does not require access to the source code, making it ideal for testing final products.
• **Automated Tools**: DAST tools can automate the scanning process and provide quick results.
• **Real-time Feedback**: DAST provides insights into vulnerabilities during the runtime of the application.
• **Integration with CI/CD**: DAST can be integrated into Continuous Integration and Continuous Deployment pipelines for continuous security assessment.

The DAST process typically involves the following steps:

1. **Identify Target Application**: Choose the application you want to test.
2. **Configure DAST Tool**: Set up the DAST tool with the appropriate configurations (target URL, authentication credentials, etc.).
3. **Run the Scan**: Execute the scan using the DAST tool to identify vulnerabilities.
4. **Analyze Results**: Review the scan results for vulnerabilities and security issues.
5. **Remediation**: Work with developers to address and fix identified vulnerabilities.
6. **Retest**: After remediation, retest the application to ensure vulnerabilities have been resolved.

Here are some best practices for implementing DAST in your organization:

• **Regular Scanning**: Schedule regular scans to ensure ongoing security assessment.
• **Integrate with CI/CD**: Incorporate DAST into your CI/CD pipeline to catch vulnerabilities early.
• **Prioritize Findings**: Focus on critical vulnerabilities that pose significant risks to the application.
• **Training**: Provide training for developers on secure coding practices and how to address vulnerabilities found in DAST.
• **Use Multiple Tools**: Employ different DAST tools to cover various types of vulnerabilities.
