The Octopus Trading Platform implements enterprise-grade security measures to protect financial data and trading operations.

• Defense in Depth: Multiple layers of security controls
• Zero Trust: Verify every request and user
• Principle of Least Privilege: Minimal access rights
• Security by Design: Built-in security from the ground up

• SOC 2 Type II ready
• PCI DSS compliant patterns
• GDPR data protection
• Financial industry best practices

# Users must provide:
1. Username/password (something you know)
2. JWT token (something you have)
3. API key for service access (something you are)

• Algorithm: HS256 (HMAC with SHA-256)
• Expiration: 60 minutes for access tokens
• Refresh Tokens: 7 days expiration
• Secret Rotation: Automatic key rotation capability

• Hashing: bcrypt with 12 rounds
• Requirements: Minimum 8 characters, complexity rules
• Breach Protection: Password strength validation
• Account Lockout: Failed attempt protection

# Available Roles

    "admin": ["read", "write", "delete", "manage_users", "system_admin"],
    "trader": ["read", "write", "trade", "portfolio_manage"],
    "analyst": ["read", "analyze", "report"],
    "user": ["read"]
}

# Generate secure secrets (minimum 32 characters)
SECRET_KEY=$(python -c "import secrets; print(secrets.token_urlsafe(32))")
JWT_SECRET_KEY=$(python -c "import secrets; print(secrets.token_urlsafe(32))")

• octopus_app: Application user with limited privileges
• octopus_readonly: Read-only user for analytics
• postgres: Admin user (production access restricted)

-- SSL enforcement
ALTER SYSTEM SET ssl = on;
ALTER SYSTEM SET ssl_cert_file = '/path/to/server.crt';
ALTER SYSTEM SET ssl_key_file = '/path/to/server.key';

-- Connection limits
ALTER ROLE octopus_app CONNECTION LIMIT 20;

-- Enable transparent data encryption
CREATE EXTENSION IF NOT EXISTS pgcrypto;

-- Encrypt sensitive data
SELECT crypt('sensitive_data', gen_salt('bf', 8));

• Data Retention: Automatic cleanup of old data
• Compression: Secure data compression
• Backup Encryption: Encrypted database backups
