When it comes to band protocol, for security we use recent Ubuntu OS, keeping the last version of software upgraded, Firewall where ssh connections are open for only a specified host, also we use additional password protection for ssh connections for all servers( google auth). For a node itself, we use two additional centries, all of them are located in different DC in two countries in the EU. We also use a private IP connection between nodes and centries. Node IP is not visible for the ‘external world’. For monitoring, we use telegram notification like HDD monitoring, CPU usage, changed staking ratio, etc.. We also use a Grafana/Prometheus graphical stats.
