Abstract
An internet connection is an entry point for attackers who want to have access to a network. Attackers intercept traffic, send fake data and commands through spoofing of IP addresses. Sometimes, attackers disguise to get into a network have access to sensitive information that could harm the user. Networks are vulnerable because of inherent characteristics of facilitating remote access. Network security has been a preventative measure in protecting the network against unauthorized access. Files, data, and packets are kept safe and protected from authorized access with the help of network security. Network security is accomplished through hardware and software. Information on disk is vulnerable and in transit. Network Security is essential due to the increase in threat of attackers trying to attack Networks. In a network, data is broken down into units called Network Packets. TCP/IP protocol’s implementation has serious security flaws despite its usage. Firewall and Access Control List (ACL) has helped in curbing open door policy of the computer systems to attackers over a network. This paper discusses the security aspect of a network and demonstrates the function of Firewall as well as Access Control list within a TCP/IP network using CISCO packet tracer, the configuration of firewall on a TCP/IP network to deny a terminal to have access to the server and other host devices, the function of Dynamic Host Configuration Protocol (DHCP) in automatic allocation of IP addresses to generic machines and configuration of Access Control List (ACL) within a network which consist of a server, a router, a switch and three personal computers.
