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+.
