The firewall in simple terms is a barrier set to restrict the flow of website traffic
to or from a network. Now, the barrier could be software or hardware alone or
could be  the  combination of  both to  achieve  the results.  The entire  flow of

Though the primary goal of the firewall is to restrict the internet traffic flowing
into the network and from the network, there are five different types of firewalls
that  are  deployed  based  on  the  unique  requirement.  However,  one  has  to
understandthatthereisacertaindegreeofoverlapbetweenthefivetypes.Infact,  there  are  a
few sophisticated firewalls that restrict the flow from within the organization but leave
more room for the employees inside to organization to communicate with the outside
world.
What are the various types of firewalls?
1. Network  Layer  Firewall  or  Stateful  Firewall:This  type  of  firewall
actually  considers  source  address,  the destination  address  as  single  IP
packets. The Network Layer firewall encourages the particular set of IP
addresses that need to be blocked as they route the traffic directly through
them.  Due  to  this  feature,  they  tend  to  be  extremely  fast  and  more
transparent to the end users.
2. Application Layer Firewalls:These are more elaborate in nature. These
types of firewalls host the proxies and perform an in-depth analysis of all
the network traffic that passed through it. These types of firewalls are not

as they encrypt the actual address after having passed through the application.
3. Proxy  Firewalls:These  firewalls  due  to  the  level  of  filtering  of  the

4. Packet Filter Firewalls:These firewalls are usually deployed at routers
and  switches  where  the  data  packets  are  compared  to  the  predefined
criteria. In case of the packets and IP addresses of the port number do not
match, they are excluded from the list of others entering thenetwork.
5. Next-gen  Firewalls:These  are  the  most  recent  type  of  firewalls  which
integrate both the packet filter firewalls and the network layerfirewalls.
