Install Advanced Policy Firewall (APF)

Advanced Policy Firewall (APF) is an iptables(netfilter) based firewall system designed around the essential needs of today’s Linux servers. The configuration is designed to be very informative and easy to follow. The management on a day-to-day basis is conducted from the command line with the ‘apf’ command, which includes detailed usage information on all the features.

Here is the steps you need to follow to get APF installed on your server.

wget http://www.rfxnetworks.com/downloads/apf-current.tar.gz
tar -xvzf apf-current.tar.gz
cd apf-0.9.5-1/
./install.sh

That's All! APF has been successfully installed on your server.


Making use of APF to prevent DDoS attacks:

Enable Anit-DOS mode in Apf (ie in conf.apf) . Also make sure that your root's cron has an entry like the one below

*/8 * * * * root /etc/apf/ad/antidos -a >> /dev/null 2>&1

That's fine!
