The Empirical Study of the Evolution of the Next Generation Firewalls

Even after the adoption of network security policies and practices, unauthorized intrusion occurs. It is an attack in which attacker gets access to the system by means of different hacking and cracking techniques. Firewall is hardware-software based network security system that uses rules to control incoming and outgoing network packet. A firewall controls access to the resources of a network through a positive control model. There are various traditional firewalls like Packet Filters, Application-level Gateways and Circuit-level Gateways which has certain pros and cons. To overcome disadvantages the traditional firewall, next generation firewalls are introduced. This paper gives the empirical study of tradition firewalls, and its evolution to Next Generation firewall like NGFW, UTM, Threat focused its features and advantages.
