Abstract

The networks are increasing day by day and their complexity is also increasing every passing second. The businesses are going online; the payments are done online. Hence the user wants their data to be highly secured and the internet is a public network, no one is safe from threats on the internet, hence the networks must be guarded perfectly so that people can trust the internet and they will continue to work online. One of the protective mechanisms under serious consideration is the firewall [1]. A firewall secures the network at its entry points, it checks all the traffic which passes through the entry point. The allowed IPs are called trusted while disapproved IPs are called untrusted in firewall terminologies. This paper provides an overview of firewall types, functionalities, and technologies.
