FIREWALL PERMITS ONE WAY TRAFFIC. iF U ARE INSIDE THE FIREWALL, THEN YOU CAN
ACCESS THE FILES ON OTHER NETWORK IF PERMITTED BUT REVERSE IS NOT TRUE.
THEREFORE I DON'T THINK THERE WILL BE ANY SECURITY AS PER YOUR COMPANY'S
PLAN. MORE OVER YOU CAN DEFINE APPLICATION PORT TO BE MORE SPECIFIC.

Hi,
A department in my company wants to permit PC's in our network to access
files in machines on an external network using Netbios file-sharing. I'm
being told that this does not open any loopholes in our security, because:
(a) we can connect our network to the external one using a Checkpoint
Firewall, with a rule permitting NBT connections from our internal PCs to
the external machines containing the files. There will be no rule permitting
a reverse connection.
(b) there will be no shared disks on our network, and the Checkpoint rules
will enforce this.
(c) ergo, our network is not exposed in any way.
I am not quite convinced - can anyone give me some more information or
pointers on this?
TIA & Regards
Prabhakar D. Mallya
