Для безопасной работы над совместным проектом важно уметь управлять полномочиями и правами доступа. Этой теме посвящён наш вебинар «Тонкости управления пользователями и доступом в облачном окружении». На примере Yandex Identity and Access Management — сервиса идентификации и контроля доступа — мы расскажем, как выстроить процессы так, чтобы все операции над ресурсами выполнялись только пользователями с необходимыми правами. На встрече мы разберём различные сценарии работы, важные технические особенности сервиса IAM и затронем следующие темы: • рекомендации по выстраиванию ресурсной модели; • возможности ролевой модели; • привилегированные пользователи и безопасность их учётных записей; • работа с группами пользователей; • события безопасности, связанные с управлением пользователями и группами. Вебинар будет полезен архитекторам, разработчикам, специалистам по безопасности уровня middle+. Зарегистрироваться на вебинар ➡️
