firewalld Audit
Overview
firewalld provides a dynamically managed firewall with support for network/firewall “zones” to assign a level of trust to a network and its associated connections, interfaces or sources. It has support for IPv4, IPv6, Ethernet bridges and also for IPSet firewall settings.
The log from firewalld must be re-routed through syslog to the Event Manager monitoring node.
NOTE: See https://firewalld.org/documentation/ for more information on how to configure this option.
