CONTEXTE<\/strong><\/h3>\n

 <\/p>\n

Le groupe CASTEL disposait d\u2019un parc de plus de 100 firewalls g\u00e9r\u00e9s de mani\u00e8re h\u00e9t\u00e9rog\u00e8ne, avec des r\u00e8gles et une nomenclature peu uniformes. Cette situation complexifiait la gestion quotidienne et la supervision de la s\u00e9curit\u00e9 r\u00e9seau sur l\u2019ensemble des sites.<\/p>\n

 <\/p>\n

BESOINS<\/strong><\/h3>\n

 <\/p>\n

Mettre en place une convention de nommage et de configuration unifi\u00e9e pour tous les firewalls.<\/p>\n

Simplifier la maintenance et le support, tout en renfor\u00e7ant la visibilit\u00e9 sur l\u2019\u00e9tat du r\u00e9seau.<\/p>\n

Assurer un MCO (Maintenance en Conditions Op\u00e9rationnelles) r\u00e9actif et adapt\u00e9 \u00e0 un parc aussi vaste.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/section>\n\n\n\n

Approche<\/h5>\n

  • \n
    Approche<\/div>\n

    Audit initial<\/strong> : Analyse de l\u2019existant (noms, r\u00e8gles, configurations) et recensement des besoins de chaque site pour d\u00e9finir un standard adapt\u00e9.<\/p>\n

     <\/p>\n

    Standardisation<\/strong> : \u00c9laboration d\u2019une charte de nommage et de configuration, int\u00e9grant la segmentation r\u00e9seau, les bonnes pratiques de s\u00e9curit\u00e9 et les exigences de CASTEL.<\/p>\n

     <\/p>\n

    Renommage<\/strong> : D\u00e9ploiement progressif de la nouvelle nomenclature, correction des r\u00e8gles obsol\u00e8tes et alignement des configurations.<\/p>\n

     <\/p>\n

    MCO<\/strong> : Mise en place d\u2019une supervision centralis\u00e9e, d\u2019un support 24h\/24 et d\u2019un processus d\u2019alerte rapide afin de traiter efficacement les demandes et les incidents.<\/p>\n

     <\/p>\n

    Performance<\/strong> : Mise en place de SLA pour les prises en charge et et les temps de r\u00e9solution en fonction de la priorit\u00e9, de l\u2019urgence et de la complexit\u00e9.<\/p>\n<\/div>\n <\/li>\n <\/ul>\n <\/div>\n

    R\u00e9sultats<\/h5>\n
      \n
    • \n
      R\u00e9sultats<\/div>\n

      Gestion simplifi\u00e9e<\/strong> : Une nomenclature claire facilite l\u2019identification des \u00e9quipements et la r\u00e9solution des demandes et des incidents sur l\u2019ensemble du r\u00e9seau.<\/p>\n

       <\/p>\n

      S\u00e9curit\u00e9 renforc\u00e9e<\/strong> : Des r\u00e8gles harmonis\u00e9es et mises \u00e0 jour r\u00e9duisent les vuln\u00e9rabilit\u00e9s et am\u00e9liorent la tra\u00e7abilit\u00e9 des changements.<\/p>\n

       <\/p>\n

      R\u00e9duction des temps d\u2019arr\u00eat<\/strong> : Un MCO r\u00e9actif et structur\u00e9 pr\u00e9vient les interruptions prolong\u00e9es et limite l\u2019impact op\u00e9rationnel.<\/p>\n

       <\/p>\n

      Visibilit\u00e9 accrue<\/strong> : La centralisation des configurations et des rapports d\u2019incidents offre une meilleure compr\u00e9hension de l\u2019\u00e9tat global du r\u00e9seau.<\/p>\n<\/div>\n <\/li>\n <\/ul>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n
