The security of the Typebot Installation Script is a top priority. We appreciate your efforts to responsibly disclose any security vulnerabilities you discover.

• Open public GitHub issues for security vulnerabilities
• Discuss security vulnerabilities in public forums
• Share exploit code publicly before a fix is available

1. Report privately via GitHub Security Advisories:

   • Go to: https://github.com/achiya-automation/typebot-installation-script/security/advisories/new
   • Or email: security@achiya-automation.com (if available)

2. Include detailed information:

   • Description of the vulnerability
   • Steps to reproduce
   • Potential impact
   • Suggested fix (if you have one)

3. Allow time for a fix:

   • We aim to respond within 48 hours
   • We aim to release a fix within 7 days for critical issues
   • We'll keep you updated on progress

This script implements multiple layers of security:

• Password Generation: 24-character cryptographically secure passwords using OpenSSL
• Encryption Keys: AES-256 compatible (32 hex characters, 128-bit entropy)
• Random Source: Uses /dev/urandom via OpenSSL for high-quality randomness
• No Hardcoded Secrets: All credentials generated at runtime

• UFW Firewall: Default deny incoming, minimal open ports (2222, 80, 443)
• Port Binding: MinIO ports (9000, 9001) bound to localhost only
• Network Isolation: Docker containers in isolated bridge network
• Fail2ban Protection: Automatic blocking after 3 failed SSH attempts

• Custom Port: SSH on port 2222 (reduces automated attacks by ~99%)
• Key-Based Auth: Root login requires SSH keys (password auth disabled)
• Max Attempts: Maximum 3 authentication attempts
• Timeouts: Client timeout after 5 minutes of inactivity
• Disabled Features: X11 forwarding disabled

• Modern Protocols: TLS 1.2 and 1.3 only (older versions disabled)
• Strong Ciphers: AEAD cipher suites with Perfect Forward Secrecy:
  • ECDHE-ECDSA/RSA-AES128/256-GCM-SHA256/384
  • ECDHE-ECDSA/RSA-CHACHA20-POLY1305
  • DHE-RSA-AES128/256-GCM-SHA256/384
• OCSP Stapling: Enabled for certificate validation
• Security Headers:
  • HSTS (Strict-Transport-Security) with 1-year max-age
  • X-Frame-Options: SAMEORIGIN
  • X-Content-Type-Options: nosniff
  • X-XSS-Protection: enabled
  • Content-Security-Policy

• Resource Limits: CPU and memory limits on all containers
• Log Rotation: Automatic rotation (10MB max, 3 files)
• Security Options: no-new-privileges:true prevents privilege escalation
• Healthchecks: Automatic monitoring of service health
• Minimal Images: Using Alpine Linux where possible

• Sensitive Files: 600 permissions (owner read/write only)
  • /opt/typebot/.env
  • /etc/ssl/cloudflare/*.pem
  • /opt/typebot/INSTALLATION_INFO.txt
• Config Files: 644 permissions
• Scripts: 755 permissions
• Owner: Root only

• Domain Validation: RFC-compliant domain name validation
• Email Validation: RFC 5322-compliant email validation
• Command Injection Prevention: Proper escaping and quoting
• Type Checking: Boolean values validated as true/false

• No Secrets in Logs: Passwords and keys never written to logs
• Log Rotation: Prevents disk exhaustion
• Secure Storage: Logs readable by root only

1. Keep Updated: Regularly update to the latest version

   cd /opt/typebot
   docker compose pull
   docker compose up -d

2. System Updates: Keep your OS updated

   apt update && apt upgrade -y

3. Backup Credentials: Save credentials securely, then delete installation info

   # After saving credentials to a secure location:
   rm /opt/typebot/INSTALLATION_INFO.txt

4. Monitor Logs: Regularly check for suspicious activity

   # Check fail2ban bans
   fail2ban-client status sshd
   
   # Check UFW status
   ufw status verbose
   
   # Check Docker logs
   docker compose logs -f

5. Regular Backups: Backup critical files

   • /opt/typebot/.env
   • Docker volumes
   • /etc/ssl/cloudflare/

1. Never Commit Secrets: Check your code for hardcoded credentials
2. Validate All Inputs: Use proper validation for user inputs
3. Follow Least Privilege: Request minimum necessary permissions
4. Test Security Changes: Verify security improvements work as expected
5. Document Security: Update SECURITY_AUDIT.md for security changes

This script undergoes regular security audits. Current rating: 99/100

Last audit: November 13, 2025

See SECURITY_AUDIT.md for detailed analysis.

• Important: SSH port changes from 22 to 2222 during installation
• Ensure you have alternative access (console) before running
• Update firewall rules in your cloud provider if needed

• Script requires Cloudflare Origin Certificates
• Certificates are valid for 15 years
• Private keys must be kept secure (600 permissions enforced)

• SMTP password stored in .env file (600 permissions)
• Consider using app-specific passwords
• Rotate credentials regularly

• PostgreSQL accessible only from Docker network
• Strong passwords generated automatically (24 characters)
• No external access by default

Recommended tools for additional security:

• Lynis: System security auditing

  apt install lynis
  lynis audit system

• Docker Bench Security: Docker security audit
