A Wired and Wireless Access Point
The wireless debate over Internet security is vast. However, there are basic guidelines to assist in making a choice for the final network design.
Local Area Network (LAN)
A local area network (LAN) is a cluster of computers connected to each other via a hub, switch or router. LANs are either wired or wireless.
Wireless LAN
A wireless LAN allows for increased accessibility. Unfortunately, data transmission and network access may be intercepted by unauthorized users if encryption is not enabled to restrict external access.
Wired LAN
A wired LAN has the drawback of limited accessibility. For instance, access to the network is dependent on proper CAT5/6 cabling with a properly placed access point. Wired networks are more secure, provided physical access to the network is monitored.
General Internet Security
A network with Internet access is only as secure as the sites being visited. Networks connected to the Internet must have updated antivirus and malware software installed. A firewall enabled router can be used to block external traffic. Furthermore, care should be taken when downloading unknown files from the Internet.
Ways to Make Wireless More Secure
As data is transmitted through the air, unauthorized interception and access is a known problem. MAC filtering is one option for limiting unauthorized access. Another option is to enable WEP/WPA encryption router.
