what are the basic elements of firewall?
Answer Posted / jks
A firewall should be able to filter packets (drop/pass them)
based on certain rules specified by the user . The rules may
be used to identify an incoming packet to the computer or
outgoing packet from the computer , it can be based on
target port number/ip add , traffic from a particular
network card etc ...
The firewall rules can be in a tabular form(saved on the
disk) from where the firewall software can read them and
implement it .
iptables firewall on Linux is a great example .
