How do you secure your home lab? - eviltoast

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?

    1. Domain auth (1 place to set passwords and SSH keys), no root SSH
    2. SSH by key only
    3. Passworded sudo (last line of defence)
    4. Only open firewall hole is OpenVPN with security dialled up high
    5. VLANs - laptops segregated from servers
    6. Strict firewall rules between VLANs
    7. TLS on everything
    8. Daily update check alerts (no automatic updates, but persists until I deal with them)
    9. Separate isolated syslog server for audit trails
    10. Cold backups
