feat(security): Phase 3 - Advanced Security Monitoring & Analytics

Browse Source 
🎯 **Phase 3 полностью завершена - Система аудита и мониторинга**

✅ **Основные компоненты:**
- Advanced Audit Reporting - детальная аналитика и отчеты
- Real-time Security Alerts - мгновенные уведомления и эскалация
- Security Dashboard GraphQL API - полнофункциональный API для админки
- Automated Threat Detection - ML-алгоритмы обнаружения угроз
- External Monitoring Integration - интеграция с SIEM/SOC системами

📊 **Advanced Audit Reporting:**
- Детальные отчеты по безопасности за любой период
- Аналитика пользователей с risk scoring
- Отчеты по организациям и соблюдению требований
- Анализ трендов безопасности с прогнозированием
- Обнаружение аномалий и подозрительных паттернов

🚨 **Real-time Security Alerts:**
- Настраиваемые правила мониторинга (rate limit, anomaly, pattern matching)
- Автоматическая эскалация по критичности
- Мульти-канальные уведомления (Email, SMS, Slack, Teams, PagerDuty)
- EventEmitter архитектура для real-time обработки
- Интеллектуальное подавление ложных срабатываний

📋 **Security Dashboard GraphQL API:**
- Полный набор запросов для административной панели
- Real-time метрики и статистика
- Управление алертами и правилами безопасности
- Генерация отчетов в различных форматах
- Subscription support для live обновлений

🤖 **Automated Threat Detection:**
- 4 базовые модели угроз с ML-подходом
- Профилирование пользователей на базе поведенческих паттернов
- Автоматическое обучение моделей на обратной связи
- Обнаружение: data scraping, competitor intelligence, insider threats, account compromise
- Confidence scoring и adaptive thresholds

🔗 **External Monitoring Integration:**
- SIEM интеграция (Splunk, Elastic SIEM, QRadar, Sentinel)
- Metrics экспорт (Prometheus, Datadog, New Relic, Grafana)
- Уведомления (Slack, Teams, PagerDuty, Webhooks)
- Поддержка форматов: CEF, JSON, Syslog
- Автоматический retry и health checking

🛡️ **Архитектурные решения:**
- Event-driven architecture с EventEmitter
- Singleton паттерн для системных сервисов
- Буферизация и batch обработка для производительности
- Feature flags для постепенного rollout
- Graceful error handling и logging

⚙️ **Конфигурация через env переменные:**
- Гибкая настройка всех интеграций
- Поддержка multiple SIEM и monitoring платформ
- Настраиваемые пороги и правила
- Debug и production режимы

📈 **Производительность:**
- Асинхронная обработка событий
- Batch отправка метрик и событий
- Кеширование результатов анализа
- Оптимизированные SQL запросы для аналитики
- Rate limiting для защиты от перегрузки

🎯 **Готово к Phase 4:** Security Testing Framework
