I was hoping to learn more and create a script.
We want minimal software on the Box and am I right in assuming that it will be more secure if I run a script while booting.
We are a University and have lots of IT students happy to try and break stuff
Am I right that the order that I add things to the script is the order they will be processed?
If so then if I Flush the iptables first
Allow TCP and UDP from prot 53 for the DHCP
Then allow the INPUT from the two servers that I require
Then DROP everything else
