I have been set the task of analysing a firewall log and then creating a visualisation of this log. My first task is to work out the most important data in the firewall log here is one line of the log 
Date/time    Syslog priority    Operation    Message code    Protocol 
+   Source IP    Destination IP    Source hostname    Destination host
+name    Source port    Destination port    Destination service    Dir
+ection    Connections built    Connections torn down

There are the column names. What sort of information am I looking forward to find attacks in the firewall log and also how can I use Perl to flag certain rows for certain attacks. If you require more information about the scenario I will include it.
