Hi , I have implemented firewall in my linux machine using iptables . It is able to prevent attacks and LOG just before dropping packets . Since i know a little about iptables , i could go thru /var/log/messages and find out information about attacks . Is there any application which will analyze logs and give a brief information to user about the attacks ? For example , suppose there was a syn flood attack ,the application should analyse the /var/log/messages or by some means should know about the attack and let the user know about that .If there is no application , could you give some hints on how to develop an application .Any comment is appreciated .
