Download file to see previous pages All the computers connected to a network justify the potential of a firewall, whether it is a desktop system or thousands of servers that create the network of a corporation, a traveling salesperson’s laptop connected to the wireless communication network, or someone’s new PC with a dial uplink to the web (Mitchell, 2012; Shelly, Cashman, & Vermaat, 2005; Northrup, 2012). This paper presents an overview of the firewall security systems. The research outlines the applications and advantages of firewalls. This research also shows that firewalls are not the ultimate solution to ensure security.

When communication systems and computer networks are connected jointly a different level of trust frequently exists on various sides of the connection. In this scenario, the word “Trust” outlines that a business considers that equally the software and the clients on its computers are not malicious. Hence, network firewalls ensure and implement trust boundaries, which are established for a variety of reasons. Some of the fundamental reasons are outlined below (Ingham & Forrest, 2005; Rhodes-Ousley, Bragg, & Strassberg, 2003; Turban, Leidner, McLean, & Wetherbe, 2005):

Operating systems keep huge records of the less protected configuration of system working and operations. For instance, Windows 98 and Windows 95 were extensively distributed with the Windows file-sharing approach incorporated by default. On the other hand, in such a configuration and system setting, there are numerous viruses that exploited this system setting with severe vulnerability. In addition, some other instances of such OS security issues are the Red-Hat Linux editions 7 and 6.2. These operating systems were extensively weak to deal with 3 remote system exploitation attacks when the operating system was installed using by default OS security setting. ...Download file to see next pages Read More
