 **Description**
 The [firewall] section defines firewall parameters. The banforge init command automatically detects your installed firewall (nftables, iptables, ufw, firewalld). For firewalls that require a configuration file, specify the path in the config parameter.
 
 The [[service]] section is configured manually. Currently, only nginx is supported. To add a service, create a [[service]] block and specify the log_path to the nginx log file you want to monitor.

+logging require in format "file" or "journald"
+if you use journald logging, log_path require in format "service_name"
