DevSecOps Pipeline Security Blueprint

Application Security & DevSecOps Framework — Secure SDLC Toolkit

After implementing secure development lifecycles where a single SQL injection in a healthcare application could expose millions of patient records, I built this framework because shifting security left means more than adding a SAST scanner to your CI pipeline — it means embedding security into requirements, design, coding, testing, and deployment with feedback loops that actually reach developers.

The core gap: OWASP Top 10 hasn't fundamentally changed in a decade because the same vulnerability classes keep appearing. Injection (CWE-89), Broken Access Control (CWE-284), and Security Misconfiguration (CWE-16) persist because security tooling produces findings that developers can't prioritize and security teams can't explain in development terms.

What You Get

• Secure SDLC Framework — Security activities mapped to each SDLC phase: threat modeling in design (STRIDE/PASTA methodology templates), secure coding standards by language (Java, Python, Node.js, .NET, Go), security testing requirements in QA, and pre-deployment security gates with go/no-go criteria.
• SAST/DAST/SCA Pipeline Configurations — CI/CD pipeline templates (GitHub Actions, GitLab CI, Azure DevOps) integrating: static analysis (Semgrep, CodeQL), dynamic testing (OWASP ZAP, Burp Suite CI), dependency scanning (Dependabot, Snyk), secret detection (TruffleHog, GitLeaks), and infrastructure-as-code scanning (Checkov, tfsec).
• Threat Modeling Templates — STRIDE threat model templates for common architectures: web application, API service, microservices, mobile app, and serverless function. Includes data flow diagrams, trust boundary identification, threat enumeration, and risk rating methodology.
• Vulnerability Management for Code — Triage workflow for SAST/DAST findings: severity classification (not just tool severity — contextual risk), false positive identification criteria, remediation guidance by vulnerability class, and SLA framework (Critical: next sprint, High: 2 sprints, Medium: backlog, Low: tech debt tracker).
• Security Champions Program — Program structure for embedding security advocates in each development team. Includes: champion role description, training curriculum (OWASP Top 10, secure code review, threat modeling), quarterly meeting agendas, and recognition/incentive framework.

Brownfield Implementation

Phase 1 (Weeks 1-4): Integrate dependency scanning (SCA) and secret detection into all CI pipelines — highest impact, lowest friction. Phase 2 (Weeks 5-10): Deploy SAST scanning with tuned rulesets (disable noisy rules, focus on high-confidence findings). Phase 3 (Weeks 11-16): Establish threat modeling practice for new features and significant changes. Phase 4 (Weeks 17-22): Launch security champions program and implement DAST for pre-production environments.

Scope Limitations

Covers web application, API, and cloud-native application security. Does not cover mobile application security testing (MAST), embedded systems security, firmware security, or mainframe application security. Assumes modern CI/CD pipeline (GitHub, GitLab, Azure DevOps, or Jenkins).

Audit Evidence

Satisfies NIST SP 800-53 SA-11 (Developer Testing), SA-15 (Development Process), SI-10 (Information Input Validation), and CM-4 (Impact Analyses). Generates: secure SDLC policy documentation, SAST/DAST scan results with remediation tracking, threat model artifacts, security training records for developers, and vulnerability management metrics required for PCI DSS v4.0 Req 6.3.2, SOC 2 CC8.1, and FedRAMP SA control family evidence.
