Therefore, firewall is an effective solution to deal with these issues. This paper will present a detailed analysis, implementation, and working of the hardware firewall technology. This paper will also outline the role of firewalls in the security matters.
The massive utilization of the internet and the World Wide Web places networks at even larger danger of unwanted threats. In addition, many corporations distribute information on the internet (using web sites), while remaining have workers who distribute information to the internet from the corporation’s network or download material from the internet (Norton). At the present, increasing numbers of organizations are exposing their personal networks to internet traffic; therefore, the implementation of firewalls has turned out to be a basic requirement. In addition, the firewall stops illegal communication inside and outside of the network, facilitating the company to implement a security strategy on traffic running between its network and the Internet (Laudon and Laudon; Turban, Leidner and McLean; Turban, Rainer and Potter, Introduction to Information Technology,3rd Edition). In addition, Firewalls can be either software or hardware. However, the best firewall arrangement will contain both (Beal). In point of fact, a firewall can divide a network into several domains. A general execution the firewall has the Internet as un-trusted domain; a semi trusted and a semi secure network, acknowledged the demilitarized zone (DMZ), as an additional domain; and an organization’s computers as third domain (Silberschatz, Galvin and Gagne 673).
“Hardware firewalls are external devices that perform job of a guard between organization’s network (office or home) and external networks (the internet)” (Antivirus-Firewall-Spyware). According to Beal (2009), the hardware firewalls are
