Please reply to the following MCI Mail address: 692-1709
You are asking some very basic questions about physical network security
that are better addressed in some books rather than through this list. I
don't mean to discourage you from participating or asking basic questions,
but the questions you ask will lead to other predictable questions, and you
might be better served by really having a good introduction to the subject
presented all at once rather than requiring you to ask the right questions
in the right order to get the right answers. I do not know where you are
located but I am sure than many people on this list could help you get
access to this material.

Need help! Regarding internet security.
Anyone has paper/doc/info how much security provided by ROUTER that's
connected to the
net?
Correct me if I'm wrong, below is what I understand.
1. Router sit in Layer 3 (network layer) and does packet filtering only. It
check all packet
forward to it and route to its destination if it knows else it drop the
packet.
2. Administrator can only block IP addresses (range of addresses) that
he/she
feel should be
allowed.
3. Facility such as FTP, telnet, tftp, rlogin, rsh and other internet
services could not be blocked
thru ROUTER instead it can only be blocked in internet server host.
Finally, I would appreciate if anyone could shed some lights on the below:
Internet FTP facility- how this facility could harm one's server that is
connected to the net. Is that
possible hacker could use this facility to hack in.
How about Telnet, SMTP, rlogin (any other ) facilities ? How these
facilities
could open door to
hacker ?
Thanks.
