Rol tabanl\u0131 eri\u015fim nedir<\/strong><\/h1>\n

Giri\u015f<\/strong><\/h3>\n

Rol tabanl\u0131 eri\u015fim, yani RBAC (Role-Based Access Control)<\/strong>, kurumsal sistemlerde kullan\u0131c\u0131lar\u0131n veriye ve uygulamalara eri\u015fimini rol tan\u0131mlar\u0131na g\u00f6re s\u0131n\u0131rlayan bir g\u00fcvenlik modelidir. RBAC, do\u011fru ki\u015filerin do\u011fru kaynaklara eri\u015fmesini sa\u011flar, gereksiz eri\u015fimleri azalt\u0131r ve g\u00fcvenlik, gizlilik ile uyumluluk gereksinimlerine yan\u0131t verir. Bu yakla\u015f\u0131m \u00f6zellikle SAP ve kurumsal yapay zeka platformlar\u0131nda kritik bir g\u00fcvenlik mekanizmas\u0131 olarak konumlan\u0131r.<\/p>\n
