Node Security

User account

In order to run the Ethereum software the image deletes the default ubuntu user account, enables ssh access, and creates a system user called ethereum, all these steps are done by our installation script. Also, on first ethereum user login, it asks the user to set a new safe password.

You can access the device using a keyboard / monitor or through SSH.

UFW

We included the UFW firewall with a set of policies according to the Ethereum software installed.

It is disabled by default (as usually we run the devices behind a router) but you can enable it by running:

systemctl enable ufw
systemctl start ufw
