hi,
Nowadays, personal firewall concept has been extended a lot. It
acts not only a packets filter but a security control center of PC. It
integrates some features together including firewall(packet filter),
AntiVirus(including malious code and grayware detection), VPN
Client(IPSec and 802.1X), parents control, web filter and so on.

Hello everyone,
I wanted to get the opinions of experts before I carry on with my project. I
am curently writting a thesis on the limitations of firewall technology,
for now it seems that firewall technology for the gateway is pretty much
covered. However, noone seems to have focused on firewall technology for
clients (on big networks), home firewalls such as ZoneAlarm are useless for
a network with many PCs because it cant be managed centrally and it asks the
user if they want to create a new rule when somthing tries to get out.
In my thesis I was going to say that these are the problems and the
solutions was to write a firewall system that can be managed centrally (via
web interface), also for technical universities where students maybe
writting network software and using their own protocols, I was going to see
if I could create some kind of "protocol creator" for admins. Originally my
thesis was going to be about security corporation sized networks, but in my
research I have come across a few other things.
IEEE802.1x and IPSec can apparently replace client-side firewalls, I dont
really know much about those two technologies, but I am still researching.
If these two techologies are better than client-side firewalls and or cost
less, I shall focus my thesis on small company networks (who cant afford
good network technology or a full-time net admin).
My thesis was going to be centered around the fact that machines within huge
networks get infected by malware and such, either by websites or via
removable media, I am hoping that my firewall I idea would: stop sending
keylogger and spyware details back to the "hacker" and stop viruses/worms
spreading from the infected client.
So, what client-side technologies do corporations use (if any)?
Are there any limitations for IPSec and 802.1X?
What are your opinions on what I was saying about client-side firewalls?
Thank you for your answers,
Davie Elliott.
