FreeBSD Edition Encryption

Pars Enterprise FreeBSD edition full platform encryption method including Boot system and password on the top with physical token.

PART I - UFS METHOD

Pars Enterprise FreeBSD edition full encryption with UFS filesystem

PART II - ZFS METHOD

Pars Enterprise FreeBSD full encryption with ZFS filesystem

Default values for the current existing customized operating system:

### loading FreeBSD operating system from live environment

# sysctl kern.disks or gpart show ada0/da0

Creating temporary folders to clone the current operating system:

# mkdir /mnt/backup

Mounting backup volume before cloning:

# kldload ext2fs

# mount -t ext2fs /dev/dax /mnt/backup

Cloning the current customized operating system:

# dump -0af /mnt/backup/image.dump /dev/adax

Full formatting storage before encryption:

# gpart destroy -F ada0

# dd if=/dev/urandom of=/dev/ada0 bs=1m count=1

Performing the partitioning scenario after full formatting:

# gpart create -s gpt ada0

# gpart add -t freebsd-swap -l swapfs -s 32g -a 1m ada0

# gpart add -t freebsd-ufs -l rootfs -s 100g -a 1m ada0

# gpart add -t freebsd-ufs -l homefs -a 1m ada0

# gpart destroy -F da0(token)

# dd if=/dev/urandom of=/dev/da0 bs=64k count=1

# gpart create -s gpt da0

# gpart add -t freebsd-boot -s 512k -a 4k da0

# gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 da0

# gpart set -a active -i 1 da0

# gpart add -t freebsd-ufs -l bootfs -s 1g -a 1m da0

# newfs -O2 -U -j -m6 /dev/gpt/bootfs

# gpart set -a bootme -i 2 da0

Generating physical token and adding it to the current encrypted storage:

# mkdir /mnt/bootvol

# mount /dev/da0s2 /mnt/bootvol

Moving the current home folder contents after encryption:

# mkdir /mnt/homevol

# mount /dev/ada0p5.eli /mnt/homevol

# mv /mnt/rootvol/home/* /mnt/homevol or ln -fs /mnt/rootvol/home/(username) /mnt/homevol/(username)

# mkdir /mnt/bootvol

# mv /mnt/rootvol/boot/* /mnt/bootvol or ln -fs /mnt/rootvol/boot /mnt/bootvol

# start

# load_geli -n 0 /dev/gpt/rootfs /dev/gpt/bootfs/.PEOST.bin

# load_geli -n 0 /dev/gpt/homefs /dev/gpt/bootfs/.PEOST.bin

Editing fstab entries with the following contents:

# vi /etc/fstab

# /dev/ada0p4.eli / ufs rw,noatime 1 1

# /dev/da0s2 /boot ufs rw,noatime 2 2

# /dev/ada0p5.eli /home ufs rw,noatime 2 2

# /dev/ada0p2.eli none swap sw 0 0

Changing user password for the current new restored operating system:

# passwd root

# passwd (username)

Clearing command line interface history and exiting:

# history -cw

Or

# echo > /root/.history && history -c && exit

Unmounting filesystems after modifications:

# umount /dev/dax /dev/da0s2 /dev/ada0p3 /dev/ada0p4.eli /dev/ada0p5.eli

# swapoff /dev/ada0p1

Removing created folders when volumes were unmounted successfully:

# rm -rf /mnt/backup /mnt/bootvol /mnt/rootvol /mnt/homevol

# geli detach /dev/ada0p4.eli /dev/ada0p5.eli

# sync && reboot
