DevSecOps Engineer — ASP.NET Static Security Analysis Pipeline (SonarQube + CI/CD) OVERVIEW We need an experienced Application Security / DevSecOps engineer to design and implement a fully automated static security code-review workflow for our ASP.NET Framework and ASP.NET Core repositories. The primary engine is SonarQube. The focus of this project is security rule engineering and pipeline automation — not general .NET development. TOOL SCOPE - Primary: SonarQube — required. Custom rule development using the SonarQube C# Plugin SDK / Roslyn analyzers. - Complementary (optional): Semgrep, CodeQL, Snyk Code. Experience with Fortify or Checkmarx is a bonus. - Supporting: OWASP Dependency-Check or Dependabot for SCA. GitLeaks / TruffleHog for secrets scanning. VULNERABILITY CLASSES — CUSTOM RULES REQUIRED SQL injection, XSS, CSRF, Auth/authz flaws, Hardcoded secrets, Sensitive data exposure, Unsafe deserialization, Weak cryptography, Insecure file uploads, Dependency misconfigurations, Razor (.cshtml) issues, ASP.NET-specific anti-patterns. DELIVERABLES 1. End-to-end CI/CD integration (GitHub Actions, Azure DevOps, or Jenkins) — every commit and PR triggers a scan; high-severity findings fail the build. 2. Minimum 5 custom security rules (source-to-sink, taint-tracking) targeting the vulnerability classes listed above. 3. Quality gates, severity thresholds, and branch policies tuned to reduce false positives. 4. Baseline suppression strategy so existing findings don't flood day-one builds. 5. Acceptance demo: green build on clean branch → injected flaws cause build failure. 6. Documentation covering installation, rule authoring, upgrades, and day-to-day triage. 7. Knowledge transfer session with the development team. WHAT TO INCLUDE IN YOUR PROPOSAL - Your approach to custom rule authoring (which tools, what methodology) - Examples of rules you have written — or willingness to demo against a sample codebase - CI platform experience (GitHub Actions / Azure DevOps / Jenkins) - How you handle false positive reduction and tuning - Similar projects completed - Estimated timeline to production-ready setup SKILLS: SonarQube, ASP.NET / ASP.NET Core, C# / .NET, Roslyn analyzers, Semgrep, CI/CD, GitHub Actions, Azure DevOps, Jenkins, Application security, SAST, DevSecOps, Documentation

Interesting project, I will deliver the full SonarQube pipeline — custom Roslyn-based security rules, CI/CD gate integration, baseline suppression, and the acceptance demo with injected flaws. For taint-tracking rules targeting SQL injection and XSS in ASP.NET, I will author them as Roslyn analyzers registered through the SonarQube C# plugin SDK — this gives you IDE-time feedback alongside pipeline enforcement, catching issues before they even reach a PR. Questions: 1) Which CI platform do you prefer — GitHub Actions, Azure DevOps, or Jenkins? 2) Are your repos primarily ASP.NET Framework, Core, or a mix of both? Looking forward to discussing further. Best regards, Kamran

Hello DevSecOps Team, I’m a focused DevSecOps engineer with deep hands-on experience designing automated SAST pipelines for ASP.NET frameworks. I’ve built secure CI/CD flows from scratch, integrating SonarQube with custom rule development (Roslyn analyzers) and risk-based quality gates to minimize noise while catching critical flaws early. In prior work, I authored and deployed multiple custom rules (source-to-sink, taint-tracking) for SQLi, XSS, insecure deserialization, and hardcoded secrets using the SonarQube C# Plugin SDK and Roslyn. I’ve wired these into GitHub Actions and Jenkins runs, plus supporting SCA/secret scanning and dependency checks to enforce security posture across PRs and commits. I also tuned false positives with baseline suppression and robust quality gates. I can deliver a production-ready setup with at least five custom rules, end-to-end CI/CD triggers on every commit/PR, green baseline builds, and a thorough doc plus a knowledge transfer session. I will confirm detailed timelines after a quick discovery. Best regards, Billy Bryan

Hello There, As per my understanding you want a fully automated DevSecOps pipeline for your ASP.NET ecosystem using SonarQube for advanced static analysis and custom rule enforcement. 1) Are your SonarQube instances currently hosted on premise or in a cloud environment like SonarCloud? 2) Do you have specific compliance standards like PCI DSS or HIPAA that the custom Roslyn analyzers must prioritize? 3) Which CI CD platform like Azure DevOps or GitHub Actions should I target for the final pipeline integration? I will transform your development process into a secure and efficient factory where security risks are caught early and fixed fast. You will get total peace of mind knowing that every line of code is automatically checked for flaws before it ever reaches your customers. This setup reduces the cost of fixing bugs and protects your brand reputation by ensuring your digital products are built on a foundation of professional grade security standards.

Hello, I have built and tuned security focused CI pipelines for ASP.NET and C# codebases, with SonarQube at the center. I understand you need more than a basic scan. You want custom security rules, automated enforcement in CI, and a workflow that catches real issues without drowning the team in noise. I would set up SonarQube with custom Roslyn based rules, then wire it into your chosen CI platform so every commit and PR is checked and high severity findings break the build. I would author source to sink and taint tracking rules for the specific ASP.NET risks you listed, including SQL injection, XSS, auth flaws, secrets, and insecure deserialization. I would also tune quality gates, branch policies, and baseline suppression so existing debt is tracked cleanly while new issues stay visible. If useful, I can validate the rules against a sample codebase first and show the false positive handling before rollout. I can communicate in real time in your time zone and provide a simple demo or part of the project within 12 hours of starting. Q1: Which CI platform do you want as the primary target, GitHub Actions, Azure DevOps, or Jenkins? Q2: Do you already have a SonarQube server and C# analyzer setup, or should I include installation and upgrade steps? Q3: Which 5 to 10 patterns should I prioritize first for custom rule authoring? Best regards, Everett

Hi there, This is a security pipeline job, not just wiring SonarQube into CI. The tricky part is making custom C# rules useful without blocking every PR with noise. I’ve built SAST and CI gates for .NET teams using SonarQube, Roslyn analyzers, GitHub Actions, Azure DevOps, Jenkins, Semgrep, and secret/SCA scanners. - Set up SonarQube scanning on PRs and commits - Add quality gates that fail only on agreed high-risk findings - Write at least 5 ASP.NET-focused rules, including source-to-sink checks where Roslyn fits - Add baseline suppression for current findings - Tune false positives with test cases and safe exclusions - Demo clean build vs injected SQLi/XSS/secret-style flaws - Document rule authoring, upgrades, triage, and handoff I can get a production-ready first version done in about 10 days, depending on repo access and CI choice. Which CI system should be treated as the source of truth for branch policy enforcement: GitHub Actions, Azure DevOps, or Jenkins? Regards, Slavko
