Structure de l\u2019Active Directory<\/strong><\/h3>\n\n\n\n

L\u2019Active Directory est organis\u00e9 de mani\u00e8re hi\u00e9rarchique et structur\u00e9e<\/strong> afin de faciliter la gestion des comptes, des machines et des strat\u00e9gies de groupe (GPO<\/strong>).<\/p>\n\n\n\n

Organisation par services<\/strong><\/h4>\n\n\n\n

Chaque service de la Ville de Longjumeau<\/strong> dispose de sa propre Unit\u00e9 Organisationnelle (OU)<\/strong>. Cette s\u00e9paration permet une administration plus fluide et une gestion des droits et des strat\u00e9gies adapt\u00e9e aux besoins sp\u00e9cifiques de chaque service.<\/p>\n\n\n\n

Exemples de services repr\u00e9sent\u00e9s en tant qu\u2019OU :<\/p>\n<\/div>\n<\/div><\/div>\n\n\n\n

\u00c0 l\u2019int\u00e9rieur de chaque OU de service<\/strong>, des sous-OU<\/strong> sont cr\u00e9\u00e9es afin d\u2019affiner la gestion des objets et l\u2019application des strat\u00e9gies de groupe (GPO<\/strong>).<\/p>\n\n\n\n

Les principales sous-OU utilis\u00e9es :<\/p>\n\n\n\n

\ud83d\udd39 MACHINES<\/strong> \u2192 Contient les objets ordinateurs du service, organis\u00e9s par type de poste :<\/p>\n\n\n\n

    \n
  • LAPTOP<\/strong> : Pour les ordinateurs portables.<\/li>\n\n\n\n
  • LINUX<\/strong> : Pour les machines sous Linux.<\/li>\n\n\n\n
  • PC<\/strong> : Pour les postes fixes Windows.<\/li>\n\n\n\n
  • PostesTEST<\/strong> : Machines utilis\u00e9es pour des tests ou des validations avant d\u00e9ploiement.<\/li>\n<\/ul>\n\n\n\n

    \ud83d\udd39 UTILISATEURS<\/strong> \u2192 Gestion des comptes utilisateurs avec des classifications sp\u00e9cifiques :<\/p>\n\n\n\n

      \n
    • AVEC BAL<\/strong> : Comptes disposant d\u2019une bo\u00eete aux lettres professionnelle.<\/li>\n\n\n\n
    • BAL G\u00c9N\u00c9RIQUE<\/strong> : Bo\u00eetes aux lettres partag\u00e9es ou g\u00e9n\u00e9riques pour un usage collectif.<\/li>\n\n\n\n
    • SANS BAL<\/strong> : Comptes utilisateurs sans bo\u00eete mail, utilis\u00e9s pour des acc\u00e8s sp\u00e9cifiques.<\/li>\n<\/ul>\n\n\n\n

      Optimisation de la gestion des objets et des strat\u00e9gies de groupe (GPO)<\/strong><\/h4>\n\n\n\n

      Cette structure permet :
      \u2714 Une application pr\u00e9cise des strat\u00e9gies de groupe<\/strong> en fonction du service et du type d\u2019utilisateur\/machine.
      \u2714 Une gestion granulaire des acc\u00e8s et des droits<\/strong> sur les ressources r\u00e9seau.
      \u2714 Un d\u00e9ploiement facilit\u00e9 des logiciels et des configurations<\/strong> via les GPO appliqu\u00e9es sur chaque sous-OU.
      \u2714 Une administration centralis\u00e9e tout en maintenant une flexibilit\u00e9 d\u2019adaptation aux besoins de chaque service.<\/strong><\/p>\n<\/div>\n<\/div><\/div>\n\n\n\n

      Proposition d’am\u00e9lioration dans le cadre de mon alternance<\/strong><\/h3>\n\n\n\n

      Dans le cadre de mon alternance, j\u2019ai propos\u00e9 une optimisation de la gestion des groupes<\/strong> afin d\u2019am\u00e9liorer l\u2019organisation actuelle d\u2019Active Directory.<\/p>\n\n\n\n

      Actuellement, tous les groupes de s\u00e9curit\u00e9 et de distribution sont centralis\u00e9s dans une OU unique \u00ab\u00a0Groupes\u00a0\u00bb<\/strong>, ce qui peut rendre la gestion des droits moins pr\u00e9cise et plus difficile \u00e0 maintenir.<\/p>\n\n\n\n

      Mon id\u00e9e est de r\u00e9organiser ces groupes en les int\u00e9grant directement dans une sous-OU propre \u00e0 chaque service<\/strong>.<\/p>\n\n\n\n

      \u2705 Objectifs de cette am\u00e9lioration<\/strong> :<\/p>\n\n\n\n

        \n
      • Affiner la gestion des droits d\u2019acc\u00e8s<\/strong> pour mieux segmenter les permissions par service.<\/li>\n\n\n\n
      • Am\u00e9liorer l\u2019administration des strat\u00e9gies de groupe (GPO)<\/strong> en appliquant des r\u00e8gles plus cibl\u00e9es et adapt\u00e9es aux besoins de chaque service.<\/li>\n\n\n\n
      • Simplifier le suivi des membres des groupes<\/strong> et faciliter les audits de s\u00e9curit\u00e9.<\/li>\n\n\n\n
      • R\u00e9duire les risques d\u2019erreurs li\u00e9s \u00e0 une gestion centralis\u00e9e des groupes.<\/li>\n<\/ul>\n\n\n\n

        Cette proposition s\u2019inscrit dans une d\u00e9marche d\u2019optimisation et de s\u00e9curisation<\/strong> de l\u2019infrastructure Active Directory, en garantissant une administration plus efficace et \u00e9volutive<\/strong>.<\/p>\n\n\n\n
