feat(security): Phase 3 - Advanced Security Monitoring & Analytics
🎯 **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 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
