Confidentiality Integrity Availability Intrusion Methods Trojan Horse Denial of Service (DOS) Email Spoofing Email-Borne Viruses Packet Sniffing Preventative Methods Firewalls Encryption Anti-virus Applications Anti Spy ware applications Conclusion Abstract As technology advances in society the need for wired and wireless networking has become essential. Each of these types of networking has their advantages and disadvantages according to security. Wired networking has different hardware requirements and the range and benefits are different. Wireless networking takes into consideration the range, mobility, and the several types of hardware components needed to establish a wireless network. As you read on you will understand different types of configurations of networks and the security measures that need to be taken to ensure a secure network. Introduction Organizations rely heavily on the ability to share information throughout the organization in an efficient and productive manner. Computer networks have allowed for this technology and are now apart of almost every business. An organization has two options when it comes to setting up a network. They can use a completely wired network, which uses networking cable to connect computers, or they can use a wireless network, which uses radio frequencies to connect computer. Wireless networks have allowed organizations to become more mobile; therefore, organizations are now using a combination of both wired and wireless networks. They
