In cloud-native architectures, vulnerabilities don’t just exist in source code, they exist in container images and in runtime behavior.

To reduce risk effectively, enterprises must secure both the artifact and the application in motion.

With GitLab, DAST (Dynamic Application Security Testing) and Container Scanning are embedded directly into GitLab CI/CD, enabling automated security within the pipeline itself.

DAST: Runtime Security Validation

DAST scans a live application by interacting with it over HTTP/HTTPS, simulating attacker techniques such as:
a) SQL injection
b) Cross-Site Scripting (XSS)
c) Broken authentication
d) Insecure headers
e) API misconfigurations

Because DAST runs against a deployed environment (typically staging), it validates:
a) Server configurations
b) Routing behavior
c) Authentication flows
d) Real API responses

This ensures vulnerabilities that only appear during execution, not in static code are detected before production release.

Container Scanning: Image-Level Risk Detection

Container images often inherit vulnerabilities from:
a) Base OS layers
b) Package managers (apt, yum, apk)
c) Language dependencies (npm, pip, maven, etc.)

GitLab Container Scanning analyzes image layers and compares them against vulnerability databases to detect:
a) Known CVEs
b) Severity levels (Critical, High, Medium, Low)
c) Fix versions when available

Scanning occurs during the build stage, preventing vulnerable images from being pushed to registries or deployed to Kubernetes clusters.

Pipeline-Level Integration

Security findings are:
a) Reported directly in pipeline results
b) Linked to merge requests
c) Aggregated in a centralized vulnerability dashboard
d) Enforceable through security policies

This tight integration ensures that security gates can automatically block deployments if predefined severity thresholds are exceeded.

Why This Matters for Enterprises

Combining DAST and Container Scanning provides:
a) Runtime attack surface validation
b) Supply chain risk mitigation
c) Shift-left security automation
d) Continuous compliance enforcement

Instead of treating security as a separate toolchain, GitLab integrates it directly into the development lifecycle.
