La Direction des Syst\u00e8mes d\u2019Information (DSI) de la mairie de Longjumeau joue un r\u00f4le central dans la modernisation et la s\u00e9curisation des outils num\u00e9riques municipaux. Avec un parc d\u2019environ 400 machines, elle veille au bon fonctionnement des \u00e9quipements informatiques, des r\u00e9seaux et \u00e0 la protection des donn\u00e9es sensibles, garantissant ainsi des services performants et s\u00e9curis\u00e9s pour les agents et les citoyens. La DSI pilote des projets de transformation num\u00e9rique visant \u00e0 am\u00e9liorer l\u2019accessibilit\u00e9 et l\u2019efficacit\u00e9 des outils num\u00e9rique. Elle accompagne \u00e9galement les agents dans l\u2019usage des outils num\u00e9riques, tout en veillant au respect des r\u00e9glementations, notamment en mati\u00e8re de cybers\u00e9curit\u00e9 et de protection des donn\u00e9es personnelles.<\/p>\n\n\n\n

1. Acc\u00e8s Internet et Pare-feu<\/strong> (HDV)<\/h3>\n\n\n\n

L’acc\u00e8s \u00e0 Internet est g\u00e9r\u00e9 par deux connexions WAN distinctes :<\/p>\n\n\n\n

    \n
  • WAN Orange<\/strong> acc\u00e8s internet agent (principal)<\/strong><\/li>\n\n\n\n
  • WAN Adista<\/strong> acc\u00e8s internent publique (secondaire)<\/strong><\/li>\n<\/ul>\n\n\n\n

    Ces connexions sont prot\u00e9g\u00e9es par deux pare-feu (FW-01 et FW-02), configur\u00e9s en haute disponibilit\u00e9 (HA).<\/p>\n\n\n\n

    2. C\u0153ur de R\u00e9seau<\/strong> (HDV)<\/h3>\n\n\n\n

    Derri\u00e8re les pare-feu, deux commutateurs c\u0153ur de r\u00e9seau (COEUR-1 et COEUR-2) assurent la distribution du trafic vers l\u2019ensemble de l\u2019infrastructure.<\/p>\n\n\n\n

    3. Distribution et Acc\u00e8s<\/strong> (HDV)<\/h3>\n\n\n\n

    Les commutateurs c\u0153ur de r\u00e9seau sont connect\u00e9s \u00e0 :<\/p>\n\n\n\n

      \n
    • Deux commutateurs de distribution principaux DISTRIB-01, DISTRIB-02, et DISTRIB-03) desservant les diff\u00e9rents services et utilisateurs.<\/li>\n\n\n\n
    • Deux commutateurs d\u2019acc\u00e8s SWITCH-FS-01 et SWITCH-FS-02<\/strong>, qui g\u00e8rent la connexion aux serveurs et aux \u00e9quipements critiques.<\/li>\n\n\n\n
    • Un commutateur d\u2019acc\u00e8s desservant le r\u00e9seau publique Adista et la WIFI<\/li>\n<\/ul>\n\n\n\n

      4. Infrastructure Serveur<\/strong> (HDV)<\/h3>\n\n\n\n

      L\u2019infrastructure repose sur plusieurs \u00e9quipements :<\/p>\n\n\n\n

        \n
      • SAN<\/strong> : Stockage centralis\u00e9.<\/li>\n\n\n\n
      • SRV-VEEAM<\/strong> : Serveur de sauvegarde.<\/li>\n\n\n\n
      • HYPERV01, HYPERV02, HYPERV03<\/strong> : Serveurs de virtualisation Hyper-V.<\/li>\n\n\n\n
      • SRV-DC-03<\/strong> : Serveur contr\u00f4leur de domaine physique.<\/li>\n<\/ul>\n\n\n\n

        5. Redondance sur un Second Site<\/strong><\/h3>\n\n\n\n

        Pour garantir la continuit\u00e9 des services, notre infrastructure repose sur une redondance au niveau du c\u0153ur de r\u00e9seau, du stockage (SAN) et des hyperviseurs. Ces derniers sont regroup\u00e9s en cluster de six n\u0153uds Hyper-V afin d’assurer une haute disponibilit\u00e9 des machines virtuelles. Le stockage est centralis\u00e9 sur un SAN redond\u00e9, garantissant la protection et la disponibilit\u00e9 des donn\u00e9es critiques. Toutefois, notre connexion WAN demeure un point unique de sortie via deux firewalls. L’objectif \u00e0 terme est de renforcer cette architecture en int\u00e9grant une sortie r\u00e9seau suppl\u00e9mentaire pour assurer une redondance compl\u00e8te.<\/p>\n<\/div><\/div>\n\n\n\n
