Установка обновлений из доверенных источников.
В связи со сложившейся обстановкой и введенными санкциями против Российской Федерации рекомендуется устанавливать обновления программного обеспечения только после оценки всех сопутствующих рисков.
Компенсирующие меры:
- отключение WAN-доступа к веб-интерфейсу администрирования;
- использование входных данных только из доверенных источников;
- ограничение доступа к определенному URI (/ztp/cgi-bin/handler).
