Firewalls are of two types:
-Hardware Firewall
-Software Firewall.
Firewall in simple manner is bascially the utility to provide the security over the network. These are the security measures that prevents the network’s in and out traffic to pass through the specific Security filters so that the unwanted and unsecure data can be stopped from entering into the network..
further… as a security measure it also depends on the network designer and implementer that how to use a Firewall mean to say the security measures like how to present the content filtering and Url filtering which type of firewall should be used and where to put it.
