  1. Enabling unattended updates
  2. Enable only ssh login with key
  3. Create user with sudo privileges
  4. Disable root login
  5. Enable ufw with necessary ports
  6. Disable ping
  7. Change ssh default port 21 to something else.

    Honestly, between the home lab being behind a RTR, NATed, patched & updated, and given the lack of users clicking on random crap and plugging in thumb drives from God Only Knows Where … I’d go out on a limb and say it’s already more secure than most PCs.

    There’s also no data besides what I already put on Medium and GitHub, so it’s not a very attractive target.
