Wireless laptop reviews on notebooks from major manufacturers including Toshiba, Compaq and Gateway

Broadband wired networks have existed for a long time, but it is only recently that wireless networks have begun to reach broadband speeds. However, their greatest advantage is they offer broadband speeds without the use of external wires. Wireless networks are easier to install and configure and they offer the advantage of movement freedom. Wireless technologies have evolved over the years and the latest standard is the 820.11g, offering speeds of up to 54Mbs. The next in line is the 820.11n standard, that will double the maximum transfer rate, but the new specifications are yet to be standardized. Linksys is one of Cisco’s most important divisions and it is known as one of the most important network equipment manufacturers. Cisco themselves are world leader in networking software and equipment and this guarantees the quality of Linksys’s wireless devices.

Network attacks take many forms, and it’s important to know how the potential security issues with ARP, DHCP, and MAC addresses. They’re innocent looking enough, but each of these common network protocols and addresses can be turned against us. Today, we’ll talk about what MAC Address Flooding is, how it can be used against our network, and the best defense against this attack.

A MAC Address Flooding attack is an attempt by a network intruder to overwhelm the switch memory reserved for maintenance of the MAC address table. The intruder generates a large number of frames with different source MAC addresses - all of them invalid. As the switch’s MAC address table capabilities are exhausted, valid entries cannot be made - and this results in those valid frames being broadcast instead of unicast.
