Explanation

To enable LUKS on a USB storage device with an ext4 filesystem format, the administrator needs to perform the following steps: Unmount the device if it is mounted using umount /dev/sdc (D) Create a partition table on the device using fdisk /dev/sdc (E) Format the partition with LUKS encryption using cryptsetup luksFormat /dev/sdc1 (H) Open the encrypted partition using cryptsetup luksOpen /dev/sdc1 LUKS0001 Create an ext4 filesystem on the encrypted partition using mkfs.ext4 /dev/mapper/LUKS0001 © Mount the encrypted partition using mount /dev/mapper/LUKS0001 /mnt
