DO NOT create public GitHub issues for security vulnerabilities.

Instead, please report security vulnerabilities by:

1. Email: Send details to [your-security-email@example.com]

   • Use subject line: [SECURITY] Brief description
   • Include detailed description of vulnerability
   • Include steps to reproduce
   • Include potential impact assessment

2. Encrypted Communication (preferred):

   • PGP Key: [Your PGP Key ID or link to public key]
   • Or use GitHub Security Advisories (Private vulnerability reporting)

When reporting a vulnerability, please provide:

1. Description: Clear description of the vulnerability
2. Type: Category (e.g., SQL injection, XSS, authentication bypass)
3. Impact: What an attacker could accomplish
4. Affected Components: Which files/modules are affected
5. Steps to Reproduce: Detailed reproduction steps
6. Proof of Concept: Code or screenshots (if applicable)
7. Suggested Fix: If you have one (optional but appreciated)

3. We will release a security update
4. We will coordinate public disclosure with you
5. We will credit you in the security advisory (if desired)

Initial Setup

• Change default admin password immediately
• Use strong, unique password (16+ characters)
• Store admin credentials in password manager
• Delete demo accounts before production deployment
• Set up HTTPS in production (never use HTTP)

Environment Configuration

• Use environment variables for secrets (never hardcode)
• Set strong SECRET_KEY for sessions
• Restrict file permissions on .env file (chmod 600)
• Never commit .env file to version control

Network Security

• Deploy behind reverse proxy (nginx, Caddy)
• Enable HTTPS with valid SSL certificate
• Configure security headers (see nginx example below)
• Restrict access to production server (firewall rules)

Ongoing Operations

• Review audit logs weekly
• Monitor failed login attempts
• Keep dependencies updated
• Backup databases daily
• Test restore procedure monthly
• Monitor disk space
• Review user accounts monthly

Password Security

• Use unique password (not reused from other sites)
• Use password manager
• Enable password strength meter
• Change password if suspicious activity detected

Account Security

• Log out when finished
• Don't share account credentials
• Report suspicious activity immediately
• Use strong full name and email

Code Security

• Never commit secrets or API keys
• Always use parameterized SQL queries
• Validate all user inputs
• Use type hints for better safety
• Follow principle of least privilege
• Log security events
• Write security tests

Review Checklist

• No hardcoded credentials
• No SQL injection vulnerabilities
• Proper input validation
• Proper error handling (no stack traces to users)
• Audit logging for sensitive operations
• Data isolation enforced
• HTTPS enforced in production

CSRF Protection

• ⚠️ Status: Not implemented
• Risk: Medium
• Mitigation: Streamlit provides some protection, but not comprehensive
• Roadmap: Planned for v1.1

XSS Protection

• ⚠️ Status: Partial (Streamlit provides some escaping)
• Risk: Low-Medium
• Mitigation: Avoid rendering user content as HTML
• Roadmap: Add Content Security Policy headers

DDoS Protection

• ⚠️ Status: Limited (rate limiting on logins only)
• Risk: Medium (for public deployments)
• Mitigation: Deploy behind reverse proxy with rate limiting
• Roadmap: Add application-level rate limiting for API calls

Man-in-the-Middle (MITM)

• ⚠️ Status: Requires HTTPS deployment
• Risk: High if HTTP used
• Mitigation: ALWAYS use HTTPS in production
• Roadmap: Add HTTPS enforcement

Concurrent Users

• SQLite Limit: ~5-10 concurrent users
• Risk: Database locks with >10 users
• Mitigation: Migrate to PostgreSQL for larger deployments
• Roadmap: PostgreSQL support in v1.2

Email Verification

• Status: Not implemented
• Risk: Low (account takeover via email)
• Mitigation: Manual email verification by admin
• Roadmap: Planned for v1.1

Two-Factor Authentication

• Status: Not implemented
• Risk: Medium (account compromise if password leaked)
• Mitigation: Use strong passwords, monitor audit logs
• Roadmap: Planned for v1.2

Planned Security Enhancements:

• CSRF token implementation

# Secure database files
chmod 600 data/*.db

# Secure data directory
chmod 700 data/

# Verify permissions
ls -la data/
# Should show: drwx------ (directory)
