Do not report security vulnerabilities through public GitHub issues, discussions, or pull requests.

To report a security vulnerability in AlienSec MCP Server, please send an email to the maintainers with the following information:

• A clear description of the vulnerability
• Steps to reproduce the issue
• Impact assessment (CVSS score if known)
• Any relevant proof-of-concept or exploit code (share privately)
• Your contact information (optional)

Please send vulnerability reports to: security@aliensec.dev (if available) or contact the repository maintainers directly.

We will acknowledge your report within 48 hours and provide a more detailed response within 7 days.

1. Triage: The security team will verify the vulnerability and assess its impact
2. Remediation: A fix will be developed and tested
3. Disclosure: A security advisory will be published with:
   • CVE assignment (if applicable)
   • Detailed description of the vulnerability
   • Impact assessment
   • Mitigation steps
   • Credits to the reporter (if desired)
4. Release: Patched versions will be released with the fix

• All API keys (AlienVault OTX, VirusTotal) are never logged or exposed in error messages
• Keys are validated on startup and rejected if missing
• Sensitive strings are hashed (SHA-256) before storage in database tables

• All external API communication uses HTTPS with TLS certificate validation
• Circuit breakers prevent cascading failures from API issues
• Rate limiting prevents overwhelming external APIs
• Custom User-Agent headers identify the server version

• SQLite database supports optional encryption at rest
• Use DATABASE_ENCRYPTION_KEY environment variable to enable encryption
• API keys are never persisted in plain text

• VirusTotal Rate Limiting: Token bucket algorithm with configurable limits
• Circuit Breaker: Automatically blocks failing API keys after 5 consecutive failures
• Reset Timeout: 5 minutes (configurable) before circuit breaker resets
• Half-Open State: Tests with 1 request before fully reopening

• Multiple API keys are used for redundancy only, not for bypassing rate limits
• Each API key respects individual rate limits (4 requests/minute default)
• Circuit breaker prevents rapid retries on failures
• Daily request counting prevents quota exhaustion

1. Use HTTPS: Always use HTTPS for all communications
2. Secure API Keys: Store API keys in environment variables, not in code
3. Network Isolation: Run the server in a secure network environment
4. Database Encryption: Enable database encryption with DATABASE_ENCRYPTION_KEY
5. Regular Updates: Keep dependencies updated with npm audit

1. Environment Variables: Use a secure secrets manager for production deployments
2. Container Security: If using containers, run as non-root user
3. Resource Limits: Set appropriate CPU and memory limits
4. Monitoring: Monitor server logs for suspicious activity
5. Firewall: Restrict network access to trusted sources only

Security updates are provided for the following versions:

All security advisories are published in the GitHub Security Advisories section.

We appreciate all security researchers who responsibly disclose vulnerabilities to us. Contributors who report valid security issues will be acknowledged in our Security Hall of Fame (when established).
