Dynamic vs Static Application Security Testing in the Cloud

When securing cloud applications, it's essential to understand the difference between Dynamic Application Security Testing (DAST) and Static Application Security Testing (SAST). These two approaches are vital in protecting your cloud infrastructure and ensuring robust application security.

Aspect

Dynamic Application Security Testing (DAST)

Static Application Security Testing (SAST)

Testing Method

Tests running applications in real-time to find vulnerabilities during execution.

Analyzes source code or binaries without executing the application.

Focus Area

Identifies runtime vulnerabilities and cloud-based infrastructure issues.

Focuses on early detection of coding flaws and security weaknesses in cloud applications.

Application Stage

Best used during the later stages, such as after deployment, for live systems.

Ideal for early development stages to ensure a secure cloud computing infrastructure.

Key Tools

DAST tools assess live apps for issues like broken authentication or injection flaws.

SAST tools analyze source code to uncover vulnerabilities like improper API handling.

Security Focus

Target cloud security solutions and exploits found in live applications.

Prevents flaws in code, strengthening cloud data security before release.

How to Conduct a Cloud Security Assessment

Conducting a cloud security assessment is crucial to identify vulnerabilities and ensure that your cloud infrastructure is protected. Here's a structured approach to assessing your cloud security posture.
