287 | 
288 | 1. **Fix Critical Vulnerabilities**
289 |    - Review and patch critical vulnerabilities in Docker image
290 |    - Remove any privileged container configurations
291 |    - Implement proper RBAC policies
292 | 
293 | EOF

298 | 
299 | 2. **Address High-Risk Issues**
300 |    - Update vulnerable dependencies
301 |    - Implement security contexts for all containers
302 |    - Review and fix permission issues

309 | ### Best Practices
310 | 
311 | 1. **Container Security**
312 |    - Run containers as non-root user
313 |    - Use read-only root filesystem where possible
314 |    - Implement resource limits
315 |    - Use specific image tags (not 'latest')
316 | 
317 | 2. **Network Security**
318 |    - Implement NetworkPolicies
319 |    - Use TLS for all communications
320 |    - Avoid NodePort services in production
321 | 
322 | 3. **Access Control**
323 |    - Implement RBAC policies
324 |    - Use ServiceAccounts with minimal permissions
325 |    - Enable audit logging
326 | 
327 | 4. **Secret Management**
328 |    - Use Kubernetes secrets properly
329 |    - Consider external secret management (Vault, Sealed Secrets)
330 |    - Rotate credentials regularly
331 | 
332 | ## Tools Used
333 | 
334 | - Kubesec: Kubernetes manifest security scanner
335 | - Trivy: Container vulnerability scanner
336 | - Polaris: Kubernetes policy engine
337 | - Custom security checks

  1 | # 25. Container and Security Scanning Strategy
  2 | 
  3 | Date: 2025-10-11
  4 | 
  5 | ## Status
  6 | 
  7 | Accepted
  8 | 
  9 | ## Context
 10 | 
 11 | The SonarQube MCP Server requires comprehensive security scanning to identify vulnerabilities before they reach production. As a tool that integrates with SonarQube (a security-focused platform), this project must maintain exemplary security practices. The project needs:
 12 | 
 13 | - Container vulnerability scanning for Docker images
 14 | - Source code static analysis (SAST) for security issues
 15 | - Dependency vulnerability scanning for npm packages
 16 | - Integration with GitHub Security tab for centralized visibility
 17 | - Fail-fast approach to prevent insecure releases
 18 | - SARIF format output for GitHub Advanced Security
 19 | - Supply chain security attestations (SLSA provenance)
 20 | - License compliance checking
 21 | 
 22 | Multiple scanning tools exist with different strengths:
 23 | 
 24 | - **Trivy**: Fast, comprehensive, supports multiple formats, excellent container scanning
 25 | - **Snyk**: Good UI, expensive for private repos, requires account
 26 | - **Grype**: Fast but fewer vulnerability sources
 27 | - **Clair**: More complex setup, primarily for registries
 28 | - **CodeQL**: GitHub's native SAST tool, excellent for code analysis
 29 | - **OSV-Scanner**: Google's vulnerability scanner, good for dependencies
 30 | 
 31 | ## Decision
 32 | 
 33 | We will implement a **multi-layered security scanning strategy** using multiple complementary tools:
 34 | 
 35 | ### 1. Trivy for Container Scanning
 36 | 
 37 | **Purpose**: Scan Docker images for OS and application vulnerabilities
 38 | 
 39 | **Configuration**:
 40 | 
 41 | - Severity threshold: `HIGH,CRITICAL` (blocks release)
 42 | - Formats: Table (local), SARIF (CI/CD)
 43 | - Scan targets: Built Docker images before publishing
 44 | - License scanning: GPL, LGPL, MPL allowed (configured exceptions)
 45 | 
 46 | **Integration points**:
 47 | 
 48 | - Local development: `pnpm scan:container` script
 49 | - CI/CD: Integrated in reusable-docker.yml workflow
 50 | - SARIF upload: GitHub Security tab for visibility
 51 | 
 52 | **Script**: `scripts/scan-container.sh`
 53 | 
 54 | ```bash
 55 | # Local container scanning with flexible options
 56 | ./scripts/scan-container.sh --severity HIGH,CRITICAL
 57 | ```
 58 | 
 59 | **Trivy configuration** (`.trivyignore`):
 60 | 
 61 | - Minimal ignores (only false positives)
 62 | - Each exclusion documented with reason
 63 | - Regular review of ignored CVEs
 64 | 
 65 | ### 2. CodeQL for Static Application Security Testing (SAST)
 66 | 
 67 | **Purpose**: Analyze TypeScript/JavaScript source code for security vulnerabilities
 68 | 
 69 | **Configuration**:
 70 | 
 71 | - Language: JavaScript/TypeScript
 72 | - Queries: Default CodeQL security queries
 73 | - Schedule: Weekly scans + on every PR
 74 | - Auto-fix: Enabled for supported issues
 75 | 
 76 | **Detects**:
 77 | 
 78 | - SQL injection risks
 79 | - Cross-site scripting (XSS)
 80 | - Command injection
 81 | - Path traversal
 82 | - Cryptographic issues
 83 | - Insecure deserialization
 84 | - Server-side request forgery (SSRF)
 85 | 
 86 | **Workflow**: `.github/workflows/codeql.yml`
 87 | 
 88 | ### 3. OSV-Scanner for Dependency Vulnerabilities
 89 | 
 90 | **Purpose**: Scan npm dependencies for known vulnerabilities
 91 | 
 92 | **Configuration**:
 93 | 
 94 | - Target: `pnpm-lock.yaml`
 95 | - Format: SARIF for GitHub integration
 96 | - Fail threshold: Any HIGH or CRITICAL vulnerability
 97 | - Auto-remediation: Dependabot PRs
 98 | 
 99 | **Coverage**:
100 | 
101 | - NPM packages (production and dev dependencies)
102 | - Transitive dependencies
103 | - OSV (Open Source Vulnerabilities) database
104 | - GitHub Advisory Database
105 | - NVD (National Vulnerability Database)
106 | 
107 | **Workflow**: Integrated in `.github/workflows/reusable-security.yml`
108 | 
109 | ### 4. SonarCloud for Code Quality and Security
110 | 
111 | **Purpose**: Continuous code quality and security analysis
112 | 
113 | **Configuration**:
114 | 
115 | - Project key: `sonarqube-mcp-server`
116 | - Quality gate: Must pass before merge
117 | - Coverage requirement: 80% minimum
118 | 
119 | **Security analysis**:
120 | 
121 | - Security hotspots identification
122 | - OWASP Top 10 coverage
123 | - CWE/SANS Top 25 detection
124 | - Code smells with security impact
125 | 
126 | **Integration**: Integrated in `.github/workflows/reusable-validate.yml`
127 | 
128 | ### 5. NPM Audit for Dependency Vulnerabilities
129 | 
130 | **Purpose**: Quick vulnerability check for npm dependencies
131 | 
132 | **Configuration**:
133 | 
134 | - Audit level: `critical` only (blocks pre-commit)
135 | - Run frequency: Every commit, every CI run
136 | - Automatic fixes: Manual review required
137 | 
138 | **Command**: `pnpm audit --audit-level critical`
139 | 
140 | ### Supply Chain Security
141 | 
142 | **SLSA Provenance Attestations**:
143 | 
144 | - Generated for all release artifacts
145 | - Includes Docker images, NPM packages, dist files
146 | - Verifiable with GitHub attestation API
147 | - Build provenance includes:
148 |   - Build environment details
149 |   - Builder identity
150 |   - Source repository and commit
151 |   - Build steps and inputs
152 | 
153 | **SBOM (Software Bill of Materials)**:
154 | 
155 | - Format: CycloneDX JSON
156 | - Generated with: `@cyclonedx/cdxgen`
157 | - Includes: All dependencies with versions and licenses
158 | - Attached to every GitHub release
159 | 
160 | **Command**: `pnpm sbom` → generates `sbom.cdx.json`
161 | 
162 | ## Consequences
163 | 
164 | ### Positive
165 | 
166 | - **Multi-Layered Defense**: Multiple tools catch different vulnerability types
167 | - **Container Security**: Trivy catches OS and application vulnerabilities
168 | - **Source Code Security**: CodeQL detects code-level security issues
169 | - **Dependency Security**: OSV-Scanner and npm audit protect against vulnerable dependencies
170 | - **GitHub Integration**: SARIF uploads centralize findings in Security tab
171 | - **Fail-Fast**: High/critical vulnerabilities block releases
172 | - **Supply Chain Security**: SLSA provenance and SBOM provide transparency
173 | - **License Compliance**: Trivy checks for license violations
174 | - **Local Development**: Developers can run scans locally before commit
175 | - **Comprehensive Coverage**: Covers OS packages, npm dependencies, source code
176 | - **Automated Remediation**: Dependabot creates PRs for fixable vulnerabilities
177 | - **Weekly Scans**: Scheduled CodeQL scans catch new vulnerabilities
178 | 
179 | ### Negative
180 | 
181 | - **False Positives**: Multiple tools may report false positives requiring triage
182 | - **Scan Time**: Security scans add 2-3 minutes to CI/CD pipeline
183 | - **Maintenance Overhead**: Need to maintain `.trivyignore` and exclusion lists
184 | - **Tool Updates**: Security tools require regular updates to stay current
185 | - **Noise**: Low-severity findings can create noise (mitigated with thresholds)
186 | - **Complex Triage**: Multiple tools require checking multiple interfaces
187 | - **Breaking Changes**: Tool updates may introduce new findings that break builds
188 | 
189 | ### Neutral
190 | 
191 | - **GitHub Dependency**: Heavily relies on GitHub Security features
192 | - **Learning Curve**: Team needs to understand output from multiple tools
193 | - **Update Frequency**: Vulnerability databases update frequently, findings change
194 | - **Scanner Differences**: Different tools may disagree on severity ratings
195 | 
196 | ## Implementation
197 | 
198 | ### Local Development Setup
199 | 
200 | **Install Trivy**:
201 | 
202 | ```bash
203 | # macOS
204 | brew install aquasecurity/trivy/trivy
205 | 
206 | # Linux (Ubuntu/Debian)
207 | wget -qO - https://aquasecurity.github.io/trivy-repo/deb/public.key | sudo apt-key add -
208 | echo "deb https://aquasecurity.github.io/trivy-repo/deb $(lsb_release -sc) main" | sudo tee -a /etc/apt/sources.list.d/trivy.list
209 | sudo apt-get update && sudo apt-get install trivy
210 | 
211 | # Docker
212 | alias trivy='docker run --rm -v /var/run/docker.sock:/var/run/docker.sock aquasecurity/trivy:latest'
213 | ```
214 | 
215 | **Run local scans**:
216 | 
217 | ```bash
218 | # Quick scan (HIGH and CRITICAL only)
219 | pnpm scan:container
220 | 
221 | # Full scan (all severities)
222 | ./scripts/scan-container.sh --severity UNKNOWN,LOW,MEDIUM,HIGH,CRITICAL
223 | 
224 | # Scan and generate SARIF report
225 | pnpm scan:container:sarif
226 | 
227 | # Scan specific image
228 | ./scripts/scan-container.sh --image myimage:tag --skip-build
229 | 
230 | # Ignore unfixed vulnerabilities
231 | ./scripts/scan-container.sh --ignore-unfixed
232 | ```
233 | 
234 | ### CI/CD Integration
235 | 
236 | **Security workflow** (`.github/workflows/reusable-security.yml`):
237 | 
238 | ```yaml
239 | jobs:

291 | ```
292 | 
293 | ### Trivy Configuration
294 | 
295 | **License exceptions** (`.trivy.yaml` - if created):
296 | 
297 | ```yaml
298 | vulnerability:
299 |   severity:
300 |     - HIGH
301 |     - CRITICAL
302 | 
303 | license:
304 |   # Allow these open-source licenses
305 |   allowed:
306 |     - MIT
307 |     - Apache-2.0
308 |     - BSD-2-Clause
309 |     - BSD-3-Clause
310 |     - ISC
311 |     - GPL-3.0 # Allowed for this project
312 |     - LGPL-3.0
313 |     - MPL-2.0
314 | ```
315 | 
316 | **Ignore file** (`.trivyignore`):
317 | 
318 | ```
319 | # Format: CVE-ID [exp:YYYY-MM-DD] [# comment]
320 | 
321 | # Example: False positive in dev dependency
322 | # CVE-2024-12345 exp:2025-12-31 # False positive, only affects test environment
323 | 
324 | # No exceptions currently - keep this file minimal!
325 | ```
326 | 
327 | ### Remediation Workflow
328 | 
329 | When security vulnerabilities are found:
330 | 
331 | 1. **Triage**:
332 |    - Check severity (HIGH/CRITICAL = immediate fix)
333 |    - Verify it's not a false positive
334 |    - Check if fix is available
335 | 
336 | 2. **Fix**:
337 | 
338 |    ```bash
339 |    # Update base image
340 |    # In Dockerfile: FROM node:22-alpine -> node:22-alpine@sha256:...
341 | 
342 |    # Update dependencies
343 |    pnpm update <package>
344 | 
345 |    # Or update all
346 |    pnpm update --latest
347 |    ```
348 | 
349 | 3. **Verify**:
350 | 
351 |    ```bash
352 |    # Run local scan
353 |    pnpm scan:container
354 | 
355 |    # Check if vulnerability is resolved
356 |    trivy image --severity HIGH,CRITICAL myimage:tag
357 |    ```
358 | 
359 | 4. **Document** (if no fix available):
360 |    - Add to `.trivyignore` with expiration date
361 |    - Add comment explaining why it's ignored
362 |    - Create issue to track fix availability
363 | 
364 | ### Monitoring Security Findings
365 | 
366 | **GitHub Security tab**:
367 | 
368 | - Navigate to: Repository → Security → Code scanning
369 | - View all findings from CodeQL, OSV-Scanner, Trivy
370 | - Filter by severity, tool, status
371 | - Dismiss false positives with reason
372 | 
373 | **Check CLI**:
374 | 
375 | ```bash
376 | # View security alerts
377 | gh api /repos/sapientpants/sonarqube-mcp-server/code-scanning/alerts
378 | 
379 | # View specific alert
380 | gh api /repos/sapientpants/sonarqube-mcp-server/code-scanning/alerts/1
381 | ```
382 | 
383 | ## Examples
384 | 
385 | ### Example 1: Container Scan Output

416 | +----------------+------------------+----------+-------------------+
417 | 
418 | Remediation Tips:
419 | 1. Update base image to latest version
420 | 2. Update dependencies in package.json
421 | 3. Check for security advisories
422 | ```
423 | 
424 | ### Example 2: CodeQL Findings
425 | 
426 | GitHub Security tab shows:
427 | 
428 | ```
429 | Code scanning alert: SQL Injection
430 | Severity: High
431 | Tool: CodeQL
432 | Location: src/database/query.ts:45
433 | 
434 | Description:
435 | This query contains unsanitized user input, which could lead to SQL injection.
436 | 
437 | Recommendation:
438 | Use parameterized queries or an ORM to prevent SQL injection.
439 | ```
440 | 
441 | ### Example 3: SBOM Content
