Introduction The twenty-first century observed the information and computer revolution; empowering people to have instant communication and permitting them in carrying out activities using computers. The use of the computer is not limited to a single or specific industry and its use would be seen in all the industries or sectors. Presently, we are living in a world wherein nearly everyone has heard about computer technology and over sixty percent of

" The presumed isolation increases overall network security by limiting the possibility of intrusion. Rabinovitch (nd) notes that "VLANs can significantly improve security management by automatically placing unrecognized network users into a default VLAN, with minimal accessibility, secure from the rest of the network." The Media Access Control (MAC) address is commonly used as a first line of defense in the VLAN security system. Because switches do not automatically perform

This occurs when a server happens to receive more connection requests that are incomplete and that it cannot possibly handle. This kind of attack's source code were released in 2006 by 2600 and Phracks two well-known underground hacker magazines. The second threat is IP Spoofing which is an attack which involves the impersonation of a legitimate host user at the IP layer. The third one is sequence number attack.

Data destruction is when an attacker goes in and starts deleting things (Curtin, 1997). There are a number of ways that a company's network can get attacked. One being if you have a single component to provide security, an attacker only has that one thing to get around in order to gaining full control of your system. Also not having secure modems can give access to unwanted attacks. However, these

Network Design Proposal Network Requirements ABC School Stats/User Counts Having a current strength of approximately 845 students, ABC School provides education from Pre-Kindergarten to the 12th Grade. According to the requirements of The New York School District, 250 Curriculum computers along with 75 Administration computers are to be installed. The requirements for the wiring per room of layer 1 are that it should adjust a total of 25 computers, 24 of which will

Secured real time protocol (SRTP) is also being identified to enhance the security parameter of WAN and LAN network elements. "SRTP provides protection with encryption keys for wired and wireless networks including bandwidth limited channels." (Guillen and Chacon 2009 P. 690). There is also a growing use of IP secure to protect organization from the interception of data over the LAN and WAN environment. To enhance network security, Chen, Horng,
