Recommendations

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 SSL-VPN;
- использование средств межсетевого экранирования для формирования «белого» списка адресов, которым разрешён удаленный доступ;
- использование систем обнаружения вторжений для отслеживания известных индикаторов компрометации:
Записей в журналах логирования:
Logdesc=“Application crashed” and msg=“[…] application:sslvpnd,[…], Signal 11 received, Backtrace: […].
