В§ WEP is total crap & should NEVER be used on ANY wireless network unless it is the ONLY encryption available. WEP is used at the two lowest layers of the OSI model - the data link and physical layers it therefore does not offer end-to-end security. However, it has been found that WEP is not as secure as once believed.

WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. WLANs, which are over radio waves, do not have the same physical structure and therefore are more vulnerable to tampering. WEP is designed to provide the same level of security as that of a wired LANs are inherently more secure than WLANs because LANs are somewhat protected by the physicalities of their structure, having some or all part of the network inside a building that can be protected from unauthorized access. Module 3 - Wireless Local Area Networks В§ Wireless Encryption Types: WEP В§ Short for Wired Equivalent Privacy, a security protocol for wireless local area networks (WLANs) defined in the 802. Link aggregation to add bandwidth to overloaded links and to provide some measure of redundancy, although the links won't protect against switch failure because they connect the same pair of switches. fast routing at higher levels to route between those VLANs. VLANs to keep different classes of users separate while using the same physical infrastructure. Various port protection features, as it is far more likely an attacker will be on an end system port than on a switch -switch link. Some switches offer a variety of tools to combat these issues including: Spanning-tree protocol to maintain the active links of the network as a tree while allowing physical loops for redundancy. They suffer from bandwidth choke points where a lot of traffic is forced down a single link. If switches discover more MAC addresses than they can store (either through network size or through an attack) some addresses must inevitably be dropped and traffic to those addresses will be treated the same way as traffic to unknown addresses, that is essentially the same as broadcast traffic (this issue is known as failopen). If switches are not multicast aware multicast traffic will end up treated like broadcast traffic due to being directed at a MAC with no associated port. As the network grows normal broadcast traffic takes up an ever greater amount of bandwidth. n n n It is possible for any host to flood the network with broadcast traffic forming a denial of service attack against any hosts that run at the same or lower speed as the attacking device. Large amounts of broadcast traffic whether malicious, accidental or simply a side effect of network size can flood slower links and/or systems. It is possible to trick switches or hosts into sending data to your machine even if it's not intended for it, as indicated above. If any link fails some devices will be unable to communicate with other devices and if the link that fails is in a central location lots of users can be cut off from the resources they require.

N n n Module 2 - Ethernet Local Area Networks вЂ“ Part 4 More advanced networks Simple switched Ethernet networks, while an improvement over hub based Ethernet, suffer from a number of issues: They suffer from single points of failure.
