Ensure noexec option set on /tmp partition
СредњаНиво 1Аутоматскаcos
Опис
The noexec mount option specifies that the filesystem cannot contain executable binaries. Since the /tmp filesystem is only intended for temporary file storage, set this option to ensure that users cannot run executable binaries from /tmp .
Како се проверава
Метод провере: Команда љуске

if ! findmnt -kn /tmp >/dev/null 2>&1; then echo compliant; elif findmnt -kn /tmp | grep -qw -- noexec; then echo compliant; else echo /tmp' is mounted without noexec'; fi- Очекивани излаз
compliant
Како се исправља
Метод исправке: Смерница или закрпа инфраструктуре
Run the following command to remount /tmp : # mount -o remount,noexec /tmp /etc is stateless on Container-Optimized OS. Therefore, /etc cannot be used to make these changes persistent across reboots. The steps mentioned above needs to be performed after every boot.
