👨‍💻 Attacking APIs \ Атаки на API. • Программный интерфейс приложений (API) - фундаментальный элемент инноваций в современном, движимом приложениями мире. API - важная составляющая современных мобильных, SaaS и веб приложений, используемая в клиентских, партнерских и внутренних приложениях от банковской сферы, сфер розничных продаж и логистики до интернета вещей, автономных автомобилей и умных городов. • По своей природе API раскрывают логику приложения и критичные данные, например, персональные данные, именно поэтому API все чаще становятся целью злоумышленников. Стремительные инновации невозможны без безопасных API. В этой статье рассматриваются общие векторы атак на API и приводятся примеры безопасной разработки. ➡️https://blog.devsecopsguides.com/attacking-apis #devsecops
