ip spoofing protection
Hiya
we are running a firewall on our debian slink server using ipfwadm. Is
there any way to protect against ip spoofing. Ie. within the firewall
rules we have allowed a certain ip address full access from the internet
(mail/web server)... so if someone was able to obtain that ip address and
use it as his/her own to get in, he/she will succeed.
Is that really what ip spoofing is?? an outsider assigning his/her PC a
valid ip address of a companies in order to get inside the network??? If
so, how would I protect against this??
Thanx
