Introduction

In any given system , network represents the point of entry into the application . The network provides the initial gatekeepers that are responsible for controlling entrance to the servers in the system Servers are usually protected using gatekeepers of their operating system . However , they should be protected from various attacks in the network . It is also vital to make sure that the network gatekeepers are not easily reconfigured or replaced using imposters . In the case of

a nutshell , the security of a network mainly involves protecting the devices of a network and data transmitted by the network devices . The main components that make up a network which serves as the point of entry gatekeepers include the switch , the firewall and the router (Cisco Systems , Inc , 2009

Threats faced by unsecured TCP /IP network users

In almost all cases , an attacker will search for networks that are poorly configured as they will be easier to gain access and exploit them to his own advantage and to the detriment of the network user . Among the vulnerabilities that are common include weak settings installation access controls that are wide and also the use of devices that are unpatched . The main threats of network threats include , sniffing information gathering , denial of service , spoofing and session hijacking (Curtin , 1997

The gathering of information reveals comprehensive information about the network devices , system configuration and the net work topology . The attacker will first have to gather...
