Framework: The Center for Internet Security (CIS) Top 18 Controls

This safeguard advances assurance by requiring a structured process to accept and address reported vulnerabilities and by embedding testing that sees both code and behavior. Static analysis inspects source or bytecode without executing it, uncovering issues like injection points, insecure APIs, tainted data flows, or missing sanitization. Dynamic analysis executes the running application to identify problems that only appear at runtime—input validation gaps across parameters, authentication flow weaknesses, session handling flaws, or misconfigurations. When paired with SCA and container/image scanning, teams obtain a layered view: custom code risks, third-party component exposure, and environment weaknesses. Findings must flow into a tracked system with severity ratings, SLAs, and verification steps so that fixes are prioritized and validated consistently across sprints.

Effectiveness depends on tuning and fit-for-purpose coverage. Static tools should be configured per language and framework, with custom rules that reflect enterprise patterns—e.g., ensuring internal wrapper functions actually enforce parameterization. Dynamic tools need realistic test data and authenticated sessions to exercise protected paths and business logic; for APIs, include fuzzing and schema validation to expose subtle failures. Integrate scanners into CI so every merge receives fast feedback, and schedule deeper, periodic scans for full-stack scrutiny. Close the loop with automated retesting to confirm remediation, and capture root causes to update coding standards or architectural guidelines. For critical applications, complement automated testing with manual penetration testing focused on complex workflows and abuse cases. The goal is not a wall of scanner output but a reliable signal that drives predictable, risk-based fixes—turning testing into a continuous guardrail that keeps vulnerabilities from accumulating between releases.
