Configuration Model

The SecurityConfig class is the central configuration point:

class SecurityConfig:
    def __init__(
        self,
        ipinfo_token: str,
        whitelist: Optional[List[str]] = None,
        blacklist: List[str] = [],
        blocked_countries: List[str] = [],
        whitelist_countries: List[str] = [],
        blocked_user_agents: List[str] = [],
        auto_ban_threshold: int = 5,
        auto_ban_duration: int = 3600,
        rate_limit: int = 100,
        rate_limit_window: int = 60,
        enable_cors: bool = False,
        # ... other parameters
    ):
        # ... initialization
