UFW

I use Ubuntu’s Uncomplicated firewall because it is available on Ubuntu and it's very simple.

Install UFW

if ufw is not installed by default be sure to install it first.

Encrypted laptop setup

• Btrfs on main drive, replacing GPT/MBR
• Encrypted main drive using key file on flash drive. Add backup passphrase
• No swap, swap files (limitation of Btrfs) or swap partition (so no suspend-to-disk)
• Boot directory and grub on flash drive
• 1st flash drive partition is Vfat partition to allow for cross-platform file transfers
• Ext4 ISO partition for Linux-only data/ISO files, if desired.
• TODO - edit grub to allow booting ISOs stored on the flash drive.
