We release patches for security vulnerabilities in the following versions:

We take the security of D.A.V.E seriously. If you discover a security vulnerability, please follow these steps:

Please do not open a public GitHub issue for security vulnerabilities.

Send details to: [security@eucann.life] (or create a private security advisory on GitHub)

Include:

• Description of the vulnerability
• Steps to reproduce
• Potential impact
• Suggested fix (if available)

• Initial Response: Within 48 hours
• Status Update: Within 7 days
• Fix Timeline: Depends on severity
  • Critical: 1-3 days
  • High: 7-14 days
  • Medium: 30 days
  • Low: Next release cycle

1. We acknowledge receipt of your report
2. We investigate and validate the issue
3. We develop and test a fix
4. We release a patch
5. We publish a security advisory
6. We credit you (if desired) after disclosure

If you're deploying D.A.V.E, follow these guidelines:

Never commit .env files. Always use:

• .env.example as templates
• Environment variables in production
• Secret managers (AWS Secrets Manager, GCP Secret Manager)

• Rotate keys regularly (every 90 days)
• Use separate keys for dev/staging/production
• Restrict API key permissions to minimum required
• Monitor usage for anomalies

# Use environment variables (not hardcoded values)
environment:
  - GOOGLE_AI_API_KEY=${GOOGLE_AI_API_KEY}
  - DATABASE_URL=${DATABASE_URL}
  - SECRET_KEY=${SECRET_KEY}

• Change default passwords in docker-compose.yml
• Use strong passwords (16+ characters, mixed case, numbers, symbols)
• Restrict network access (firewall rules, VPC)
• Enable SSL/TLS for database connections
• Regular backups with encryption

D.A.V.E includes these protections:

• File size limits (50MB default)
• File type validation (7 allowed formats)
• Content scanning
• Isolated processing environment

Additional recommendations:

• Deploy antivirus scanning
• Implement rate limiting
• Monitor for suspicious uploads

• Use HTTPS in production (TLS 1.3)
• Configure CORS properly (restrict origins)
• Enable firewalls (only expose necessary ports)
• Use Web Application Firewall (WAF)

• Log security events (failed auth, suspicious activity)
• Set up alerts for anomalies
• Regular security audits
• Monitor API usage and quota

• Keep dependencies updated (use Dependabot)
• Scan for vulnerabilities (pip-audit, npm audit)
• Review security advisories regularly

• API keys provide full access to your Google AI account
• Implement rate limiting to prevent quota exhaustion
• Monitor usage for cost control and anomaly detection

• Sessions are stored in memory (not persistent)
• Consider Redis for production session storage
• Implement session expiration policies

• Uploaded files are processed in memory
• Large files may consume significant resources
• Consider worker pools for isolation

• Generated artifacts may contain sensitive data
• Implement access controls for downloads
• Consider encryption at rest

D.A.V.E is designed to assist with NIST 800-53 compliance, but:

• We are not responsible for your compliance outcomes
• Review all generated artifacts before submission
• Validate recommendations against your environment
• Consult security professionals for critical systems

D.A.V.E includes:

• ✅ Input validation and sanitization
• ✅ File type and size restrictions
• ✅ Session-based access control
• ✅ Environment variable isolation
• ✅ CORS configuration
• ✅ Error handling (no sensitive data leakage)
• ✅ Rate limiting support

D.A.V.E integrates with:

• Google Gemini AI: Data sent to Google's API (see Google's security practices)
• PostgreSQL: Open-source database
• Redis: Open-source cache

Review each service's security documentation.
