Abstract
In this technological arena, a firewall is a major tool for network security system to predetermine its basic rules so that it can control and monitor incoming and outgoing network traffic. The firewall generally restricts the faulty and unusual data entering the system. It can be categorized as host-based firewalls and network-based firewalls. There are various applications of firewall and how these firewalls can help the underwater wireless sensor network (UWSN) in protecting the sensor nodes where a huge amount of sensitive data is communicated among different countries. Firewall mainly aims to secure the network from different attacking devices and the attackers in a very efficient way. Firewall creates a barrier in which only the authorized data can be passed through after continuously checking by the firewall policies. To protect a local system and network of system from threats which are generally network based firewall is the most effective way. The design of the firewall is required to be accurate as it acts as a filter at higher protocol layer and some levels of IP-packets.
