		<description><![CDATA[Block brute force attacks with iptables
Because iptables comes standard with every Linux distribution we&#8217;ll skip right to setting up the specific firewall rules we need. In depth configuring of iptables takes a bit of understanding and is not within the scope of this article, but let&#8217;s take a look at these two statements:
sudo iptables -A INPUT -i eth0 -p tcp &#8211;dport 22 -m state &#8211;state NEW -m recent &#8211;set &#8211;name SSH
sudo iptables -A INPUT -i eth0 -p tcp &#8211;dport 22 ...]]></description>
