This project follows strict security practices to ensure ALL dependencies are downloaded from authentic sources across all package managers and systems.

All Node.js dependencies are configured to be downloaded exclusively from the official npm registry (registry.npmjs.org).

All Docker images use official, verified base images with SHA256 digests for immutable builds:

• Node.js: Official node:20-alpine from Docker Hub
• Prometheus: Official prom/prometheus from Docker Hub
• Grafana: Official grafana/grafana from Docker Hub
• Elasticsearch: Official images from docker.elastic.co
• Wazuh: Official wazuh/wazuh-manager from Docker Hub

All GitHub Actions use official, verified actions:

• actions/checkout@v4: Official GitHub action
• actions/setup-node@v4: Official GitHub action
• docker/setup-buildx-action@v3: Official Docker action
• aquasecurity/trivy-action@master: Official Trivy security scanner

Alpine Linux packages (used in Docker containers) are installed from official Alpine repositories:

• apk packages: Only from official Alpine package repository
• dumb-init: Official Alpine package for proper signal handling

1. .npmrc - Project-level npm configuration that enforces:

   • Official npm registry usage
   • Package signature verification when available
   • Security audit level settings
   • Exact version saving for better security

2. package.json - Contains security-related configurations:

   • publishConfig.registry - Ensures publishing to official registry
   • config.registry - Fallback registry configuration
   • Security-related scripts for auditing and checking dependencies

The following npm scripts are available for comprehensive security management:

# Run security audit
npm run security:audit

# Automatically fix security vulnerabilities
npm run security:audit-fix

# Check installed dependencies
npm run security:check-deps

# Check for outdated packages
npm run security:outdated

# Comprehensive dependency verification (all sources)
npm run security:verify

All dependencies in package-lock.json are verified to come from https://registry.npmjs.org/.

• All Docker images use SHA256 digests for immutable builds
• Base images are from official, verified sources
• Container security scanning with Trivy

• All actions use official, verified sources
• Actions are pinned to specific versions
• Security scanning integrated into CI/CD pipeline

• Alpine packages from official repositories only
• Package integrity verification during installation

Regular security audits are performed using multiple tools:

• npm audit for Node.js dependencies
• trivy for container and filesystem scanning
• GitHub Security Advisories integration

• Exact versions are used where possible to prevent unexpected updates
• SHA256 digests for Docker images ensure immutable builds
• Regular updates are performed in a controlled manner
• Dependencies are reviewed before updates

1. Always use official npm registry

   • Never use third-party or private registries for public packages
   • Verify registry URLs in package-lock.json

2. Regular Security Audits

   • Run npm audit regularly
   • Address high and critical vulnerabilities immediately
   • Keep dependencies up to date

3. Version Control

   • Use exact versions for critical dependencies
   • Review dependency updates before applying
   • Test thoroughly after dependency updates

4. Monitoring

   • Monitor security advisories for used packages
   • Subscribe to security notifications
   • Use automated security scanning tools

To verify all dependencies are from authentic sources:

# Comprehensive verification script (all dependency types)
npm run security:verify

# Manual verification commands:

# 1. Check NPM packages
grep "resolved" package-lock.json | grep -v "registry.npmjs.org" || echo "All NPM packages from official registry"

# 2. Check Docker images
docker images --digests | grep log-generator

# 3. Run security audit
npm audit

# 4. Check for outdated packages
npm outdated

# 5. Scan containers for vulnerabilities
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock aquasec/trivy image log-generator:latest

If a security vulnerability is discovered:

1. Immediate Assessment

   • Determine the severity and impact
   • Check if the vulnerability affects the project

2. Remediation

   • Update the affected package to a secure version
   • If no secure version exists, consider alternatives
   • Test the application after updates

3. Documentation

   • Document the vulnerability and remediation steps
   • Update security guidelines if necessary

To protect against supply chain attacks:

1. Package Integrity

   • Verify package signatures when available
   • Use package-lock.json to ensure consistent installs
   • Monitor for unexpected changes in dependencies

2. Dependency Analysis

   • Regularly review direct and transitive dependencies
   • Remove unused dependencies
   • Prefer well-maintained packages with good security records

3. Build Security

   • Use secure build environments
   • Verify build artifacts
   • Implement security scanning in CI/CD pipelines

If you discover a security vulnerability in this project:

1. Do not create a public issue
2. Contact the maintainers privately
3. Provide detailed information about the vulnerability
4. Allow time for assessment and remediation before public disclosure
