🔐 Zero Trust Architecture

"Never Trust, Always Verify" - Современный подход к кибербезопасности

🎯 Основные принципы Zero Trust

🚫
Verify Explicitly
Всегда проверяйте подлинность и авторизацию на основе всех доступных данных
🔒
Least Privilege Access
Ограничивайте доступ пользователей минимально необходимыми правами JIT/JEA
🛡️
Assume Breach
Минимизируйте радиус поражения и сегментируйте доступ
🔄
Continuous Verification
Постоянно проверяйте состояние безопасности всех активов
📊
Data-Centric Security
Фокус на защите данных, а не только периметра
🎯
End-to-End Encryption
Шифрование данных в движении и в покое
