adcfw-log is a tool for analyzing firewall logs in order to extract
meaningful information.
It is designed to be a standalone script with very few requirements that
can generate different kinds of reports, such as fully formatted reports
of what had been logged, with summaries by source or destination host,
the type of service, or protocol. There are also options to filter the input
data by date, host, protocol, service, and so on.
Only netfilter log format is supported at this time.
