Summary

Recap

• A wireless enables a mobile user to connect to a local area network (LAN) through a wireless (radio) connection.

• Wired Equivalent Privacy (WEP), a security protocol, specified in the IEEE Wi-Fi standard, 802.11b, that is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN.

• WEP is vulnerable because of relatively short IVs and keys that remain static.

• Even if WEP is enabled, MAC addresses can be easily sniffed by an attacker as they appear in the clear format. Spoofing MAC address is also easy.

• If an attacker holds wireless equipment nearby a wireless network, he will be able to perform a spoofing attack by setting up an access point (rogue) near the target wireless network.

• Wireless networks are extremely vulnerable to DoS attacks.

• A variety of hacking and monitoring tools are available for the Wireless networks as well.

• Securing wireless networks include adopting a suitable strategy as MAC address filtering, Fire walling or a combination of protocol based measures.
