This is a repository for iptables scripts to help with building up
progressively more "allowed" interaction with a Linux server in the
Cloud. The idea is that we have two base scripts:

-> BASE 1: Total Lockdown - this sets the policies for your machine to drop all inbound traffic to your server
-> BASE 2: Wide Open - this sets the policies to allow all traffic inbound to your server

Building from the BASE of Total Lockdown the scripts show how to add:

1. Pinging;
   
2. SSH/SFTP;
   
3. FTP;
   
4. DNS;
   
5. YUM (as its CentOS baseds);
   
6. HTTP;
   
7. HTTPS
