1. Comparison of Firewalls:
Within the field of computing, Firewall refers to a system for network security that
specifically monitors as well as controls the traffic present on a network having a complete
dependency upon the security rules that have been previously determined. A firewall
explicitly creates a particular barrier in between the existing internal network along with that
of the external network, which is considered to be untrusted (Wool 2018). Such external
networks might be that of internet from where individual users gather information that might
be taken into their personal systems. Hence, the firewall might have the existence at the entry
node of the network or even within the system of the user.
There is the shared existence of primary three types of firewalls, which are,
i) Packet filtering firewall.
ii) Application-layer firewall.
iii) Stateful-inspection firewall.
1.1 Packet filtering firewall:
This particularly refers to the technique of utilizing the control network access by the
monitoring over the outgoing as well as the incoming packets along with allowing all of them
to pass or place a halt upon the source as well as the destination of the IP addresses, ports and
the protocols.
Network layer firewalls put forward the definition of filtering the rule sets, which
provision with higher efficiency within the mechanisms of security (Voronkov, Martucci and
Lindskog 2020). This particular type of firewall is also termed as static filtering.
