I need some advice on network lockdown, i am purchasing a sun box, and installing solaris 9, anybody got some advice or links for locking down solaris? I am getting cox cable, high speed internet connection. And i wanna use the sun box as a firewall/gateway, so it goes like this, internet -> cox -> cable modem -> sun box -> linksys router bsfr41 -> internal network. i am using on the internal network win xp, 2000, and red hat 8. Also some help w/ pen testing would be useful too, and any service that need to be shutdown to make it more secure. What kinda tests, how to perform them, tools, etc. Would like to run my own small webserver, ssh, ftp, and spam filtering. Would i need to enable port fowarding on the router and sun box? And would it be better to enable the dhcp on the router or sun box. Is DNS for big networks? Thinking about trying to set that up. Doing all this for learning more about network security. Any help would be VERY grateful. Thanx
