1.1.3 Ensure nodev option set on /tmp partition


The nodev mount option specifies that the filesystem cannot contain special devices.


Since the /tmp filesystem is not intended to support devices, set this option to ensure that users cannot attempt to create block or character special devices in /tmp .


Run the following command to remount /tmp :

# mount -o remount,nodev /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.
