Hosts.all/Hosts.deny vs. a firewall?
So far I have the following setup:
My intention is to prevent everyone from the 'outside' from reaching my box. I do realize that anyone in my_work.domain would also be able to get at it.
It is my understanding that this will prevent anyone not in my_work.domain from getting to my box with telnet, ftp, etc. Is this correct? Is this secure? If this is indeed correct could someone tell me why I would need/want a firewall and/or what benefit it would provide me over what I already have setup? More specifically how does a firewall differ from using the hosts.allow/hosts.deny files as I described above.
Appreciate any advice on this...
