Automated Scanning, Compliance ENforcement, and Deployment
A four-layer DevSecOps framework that integrates automated security scanning directly into CI/CD pipelines with build-gating mechanisms, multi-track deployment orchestration, and AI-powered post-deployment code synchronization.
Modern CI/CD pipelines prioritize velocity. ASCEND's thesis is that velocity and security are not in tension — the tension comes from treating security scanning as a passive reporting step rather than as an active build gate. ASCEND integrates security scanning, build gating, multi-track deployment orchestration, and AI-powered synchronization into a single, platform-agnostic framework.

- Four-layer DevSecOps architecture with formal quality gate definitions.
- Platform reference configurations for GitHub Actions, GitLab CI/CD, Jenkins, and Azure DevOps.
- Multi-track deployment framework supporting blue-green, canary, and rolling strategies with automated quality gates at each promotion boundary.
- AI-powered synchronization system using AST differencing, ML conflict classification, and LLM-based resolution with property-based verification.
- Comprehensive scanning tool integration covering SonarQube, Semgrep, CodeQL, Snyk, Trivy, OWASP ZAP, Checkov, and TruffleHog.
ASCEND provides full reference configurations for four major CI/CD platforms:
| Platform | Location | Best For |
|---|---|---|
| GitHub Actions | platforms/github-actions/ |
Teams on GitHub with GHAS |
| GitLab CI/CD | platforms/gitlab-ci/ |
Fastest integration via native templates |
| Jenkins | platforms/jenkins/ |
Existing Jenkins infrastructure |
| Azure DevOps | platforms/azure-devops/ |
Microsoft enterprise ecosystems |
Example for GitHub Actions:
cp platforms/github-actions/.github/workflows/ascend-full.yml \
/path/to/your/repo/.github/workflows/Each scanning tool requires minimal configuration (API tokens, organization IDs). See quality-gates/README.md for setup instructions for each tool.
cd ai-sync
pip install -e .
ascend-sync --helpSee ai-sync/README.md for configuration.
Push a commit to your feature branch. ASCEND will execute Layer 1 scanning immediately. Passing builds progress through Layer 2, Layer 3, and Layer 4 according to your promotion rules.
The IEEE Access submission (docs/paper/) makes specific empirical claims (83.0% critical-vuln reduction, 43.5% MTTD improvement, 94.2% AI conflict-resolution accuracy, all at p < 0.001 with d > 2.0). The reproduction harness lives in evaluation/ and is wired into the root Makefile.
# Full reproduction pass (install, test, lint, eval, stats)
make repro
# Or step-by-step:
make install # editable install + dev extras
make test # pytest (25 tests)
make lint # ruff
make eval # conflict-fixtures benchmark, asserts heuristic baseline
make stats # Welch t-test + Cohen's d on aggregate-metrics.csvThe make eval target asserts the heuristic conflict classifier still achieves a 71% baseline on the bundled fixtures. The make stats target runs the analysis pipeline against a synthetic schema-demonstration CSV; reproducing the paper's actual Table IX numbers requires the NDA-protected per-repository telemetry as documented in evaluation/README.md and docs/paper/EVALUATION.md.
For the full reviewer-facing reproducibility paper trail, see docs/paper/REVIEWER_CHECKLIST.md.
ASCEND is designed for incremental adoption. Most organizations realize the majority of security value from Layer 1 alone.
| Phase | Effort | Layers | Outcome |
|---|---|---|---|
| Phase 1 | 1–2 weeks | Layer 1 | ~80% of vulnerability reduction |
| Phase 2 | 4–6 weeks | Layers 1–2 | Container & IaC coverage |
| Phase 3 | 4–6 weeks | Layers 1–3 | Multi-track deployment gates |
| Phase 4 | 8–12 weeks | Layers 1–4 | Full AI synchronization |
Start with Phase 1, measure impact, and progress only when the current phase is operating smoothly.
