**********************************************************************************
### WARNING ###
DO NOT EXPOSE NODE-RED TO THE OPEN INTERNET WITHOUT SECURING IT FIRST
Even if your Node-RED doesn’t have anything valuable, (automated) attacks will
happen and could provide a foothold in your local network
Follow the guide at https://nodered.org/docs/user-guide/runtime/securing-node-red
to setup security.
### ADDITIONAL RECOMMENDATIONS ###
– Remove the /etc/sudoers.d/010_pi-nopasswd file to require entering your password
when performing any sudo/root commands:
sudo rm -f /etc/sudoers.d/010_pi-nopasswd
– You can customise the initial settings by running:
node-red admin init
– After running Node-RED for the first time, change the ownership of the settings
file to ‚root‘ to prevent unauthorised changes:
sudo chown root:root ~/.node-red/settings.js
