Ensure nodev option set on /home partition

MediaNivel 1Automatizadacos

Descripción

The nodev mount option specifies that the filesystem cannot contain special devices. Since the user partitions are not intended to support devices, set this option to ensure that users cannot attempt to create block or character special devices.

Cómo se verifica

Método de auditoría: Comando de shell

shell
if ! findmnt -kn /home >/dev/null 2>&1; then echo compliant; elif findmnt -kn /home | grep -qw -- nodev; then echo compliant; else echo /home' is mounted without nodev'; fi
Salida esperada
compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Run the following command to remount /var : # mount -o remount,nodev /home /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.
