ciguard 0.1.0

Static security auditor for CI/CD pipelines (GitLab CI today; GitHub Actions + Jenkins in development).

ciguard

Static security auditor for CI/CD pipelines. Scans pipeline configuration files for misconfigurations, supply-chain risks, and compliance gaps. Produces prioritised reports with mappings to ISO 27001, SOC 2, and NIST CSF.

Supported today: GitLab CI (.gitlab-ci.yml) In development: GitHub Actions, Jenkins (Declarative Pipeline), SARIF output

Why

CI/CD pipelines are increasingly the highest-value attack surface in software delivery. Common misconfigurations — hardcoded secrets, unpinned images, unprotected production deployments, privileged runners — are routinely exploited (SolarWinds, Codecov, 3CX). Existing SAST tools scan application code but miss pipeline-level risks. Manual review is slow and inconsistent.

ciguard runs in seconds, produces actionable reports with compliance mapping, and is auditable enough for regulated environments.

Install

pip install ciguard

Or from source:

git clone https://github.com/Jo-Jo98/ciguard.git
cd ciguard
pip install -e .

Quick start

# Scan a pipeline (terminal summary)
ciguard scan --input .gitlab-ci.yml

# HTML report
ciguard scan --input .gitlab-ci.yml --output report.html

# JSON report (CI/API consumption)
ciguard scan --input .gitlab-ci.yml --output report.json --format json

# PDF report (audits, executive review)
ciguard scan --input .gitlab-ci.yml --output report.pdf --format pdf

# Apply organisational policies
ciguard scan --input .gitlab-ci.yml --policies policies/ --output report.html

# AI-enriched executive summary (optional, requires API key)
ANTHROPIC_API_KEY=sk-ant-... ciguard scan --input .gitlab-ci.yml --llm --output report.html

Exit codes: 0 clean, 2 critical findings, 1 error.

Features

• 19 deterministic security rules across 6 categories (Pipeline Integrity, Identity & Access, Runner Security, Artifact Handling, Deployment Governance, Supply Chain)
• Policy engine — 7 built-in organisational policies + custom YAML policies
• Scanner integrations — Semgrep CE, OpenSSF Scorecard, GitLab native security artifacts (all optional, graceful when unavailable)
• AI enrichment — optional Claude / OpenAI executive summaries and remediation plans
• Three report formats — HTML (dark, self-contained, no CDN), JSON (API-ready), PDF (8 sections, audit-grade)
• Web UI — drag-and-drop upload, live results, downloadable reports
• REST API — FastAPI with OpenAPI docs at /api/docs
• Risk scoring — weighted A–F grade with per-category breakdown
• Compliance mapping — ISO 27001, SOC 2, NIST CSF on every finding

Validated against real-world pipelines

ciguard 0.1 has been validated against 17 public GitLab CI files including the GitLab project itself, Inkscape, Wireshark, Meltano, fdroid, BuildStream, and Graphviz. PRD acceptance criteria as of v0.1:

• Recall on labelled bad fixture: 100% (14/14 expected rules fire)
• False positives on labelled good fixture: 0
• Performance: 166 ms mean parse + analyse on a synthetic 500-job pipeline (5-run mean)

Regenerate locally with python scripts/validate_corpus.py and python scripts/validate_fixtures.py.

Custom policies

Create YAML files in a policies/ directory:

# policies/my_org.yml
policies:
  - id: "ORG-001"
    name: "No Critical Findings"
    description: "Zero critical findings required before merge"
    severity: critical
    condition:
      type: no_severity
      severity: Critical
    remediation: "Resolve all Critical findings before merging"
    tags: [org, gate]

Supported condition types: no_rule_findings, max_findings, min_risk_score, no_severity, min_category_score, pipeline_check. See policies/example_org_policies.yml for a full example.

Risk scoring

Weighted score across 6 categories — each contributes a percentage of the overall score:

Category	Weight
Pipeline Integrity	25%
Identity & Access	20%
Deployment Governance	20%
Supply Chain	20%
Runner Security	7.5%
Artifact Handling	7.5%

Grades: A (90–100), B (80–89), C (70–79), D (60–69), F (<60).

Running with Docker

# Build
docker compose build

# Web UI on :8080
docker compose up web

# CLI scan
docker compose run --rm cli --input /pipeline/.gitlab-ci.yml --output /reports/report.html

Roadmap

• v0.1 — GitLab CI parser, 19 rules, policy engine, scanner integrations, HTML/JSON/PDF reports, AI enrichment, web UI
• v0.2 — GitHub Actions parser
• v0.3 — Jenkins (Declarative Pipeline only) + SARIF output
• v0.4 — Baseline / delta reports, GitHub Actions Marketplace listing
