toto 14323f7b05 perf(clickhouse): P10 — créer les 4 vues métier manquantes + corriger préfixes DB
Bug de production : view_form_bruteforce_detected, view_host_ip_ja4_rotation,
view_dashboard_entities, view_dashboard_user_agents étaient référencées dans
13 endpoints du dashboard mais n'existaient nulle part dans le schéma.
Tous ces endpoints retournaient HTTP 500 en production.

shared/clickhouse/11_views.sql (nouveau) :

  view_form_bruteforce_detected
    Source : agg_host_ip_ja4_1h (24h)
    Logique : GROUP BY (src_ip, host) HAVING count_post >= 10
    Usage   : bruteforce.py (3 endpoints), investigation_summary.py

  view_host_ip_ja4_rotation
    Source : agg_host_ip_ja4_1h (24h)
    Logique : uniqExact(ja4) par src_ip, HAVING >= 2 (rotation de fingerprint)
    Usage   : rotation.py (3 endpoints), investigation_summary.py

  view_dashboard_entities
    Source : http_logs (7 jours), UNION ALL 5 branches (ip/ja4/country/asn/host)
    Colonnes : entity_type, entity_value, src_ip, ja4, host, log_date,
               client_headers Array(String), asns Array, countries Array,
               user_agents Array
    Usage   : entities.py (5 endpoints), clustering.py

  view_dashboard_user_agents
    Source : http_logs (7 jours), GROUP BY (src_ip, ja4, hour)
    Colonnes : src_ip, ja4, hour, log_date, user_agents Array(String), requests
    Usage   : variability.py (4 endpoints), fingerprints.py (5 endpoints)
              attributes.py (2 endpoints)

deploy_schema.sh : ajout de 10_perf_indexes.sql et 11_views.sql dans la liste

routes/variability.py + fingerprints.py :
  Correction de 9 requêtes utilisant view_dashboard_user_agents sans préfixe
  de base de données → remplacé par {settings.CLICKHOUSE_DB_PROCESSING}.view_*

ja4-platform

ja4-platform is a monorepo security pipeline for TLS fingerprinting (JA4/JA3) and bot detection. It captures live network traffic, correlates TLS handshakes with HTTP requests, detects anomalous behavior using machine learning (Isolation Forest), and presents results through a SOC analyst dashboard — all backed by ClickHouse as the central data store.
