Firewall is basically used to prevent the network from
unauthorised access.
Firewall are basically 2 types
1) Hardware Firewall:-Its works on network layer and used
for packet filtering usually used for network security. Its
only allow/deny packets(ports).

H/W firewall
2) Software Firewall:- Its work at application level.It is
signature based firewall it does not bloks malicious
packets. Its only blocks predefined malicious signature.
