Started off by

  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.

Got the ideas from networkchuck

Did this on the proxmox host as well as all VMs.

Any suggestions?

I use practical security measures that match my level of exposure and don't severely limit my convienience.

If your lab isn't exposed directly to the internet, at the very least update your servers from time to time, use a string root (admin users as well) password. That's more than enough.

If your lab is exposed, the same applies but update more often. Use SSH keys.

Don't go overboard - the majority of security incidents are from lack of basic security
