Hi all
I am in the process of learning security protocols in networks. I have a few questions and hope some one might clarify,
if we are implementing packet filtering,
how do we really set up the fire wall to allows only a certain sites ( ie HTTP Requests ),
further, if we have an attack on the network and some one is pumping forged packets by establishing his identify as a router, how can the fire wall detect these forged packets.
moreover, when if i have a VPN, how can I can login thro the network and other non-registered users cannot.
and what happens to the mails, how do they all get routed in without any trouble.
I am sure some of the questions could be very basic, but I have just began going over this topic andwill be using this in my project, so will appreciate any information or techi article web site.
I did understnad HASH and RSA Algorithms, but the above few questions kept bothering me.
Thanks again
