WPA2 is the best security protocol option widely available today, and we’ll all continue to use WPA2 passwords at homes and cafes for several years. If you want better security, stop using wireless, period. Today, WPA2 remains the standard protocol for Wi-Fi security, especially due to its strong AES encryption method. The best rule of thumb is: use what you've got and be done with it. Not everyone has access to Radius-enabled hardware, hence the practical security meaning most everyone has WEP/WPA/WPA2 and, for the "wily hacker," it's not protection at all. It also improves upon the old handshake mechanism, to make it more resistant to de-auth attacks. WPA improves upon this, by combining RC4 with TKIP, which helps defend against the IV-based attacks found in WEP. See this question for more details on WEP security. There is no practical security that can protect your data if you use a wireless connection and someone wants it. Due to the severity of the break, WEP is now considered deprecated.

MAC filtering? Irrelevant since every packet is tagged with a MAC - encryption doesn't help there. WPA2? Like eating a steak with that same knife. WPA? Hot knife through a buttered bagel, a little tougher. With an 11bg wireless card, my BackTrack 2.0 CD, and well under 30 minutes, I can get into most any wireless network that doesn't use the aforementioned Radius setup. WPA (Wi-Fi Protected Access) was developed as an improvement over WEP for the IEEE 802.11i wireless network standard. In summary, WPA2 is a superior security protocol to WPA, which is in turn a superior security to WEP not only in securing your data, but also with data transfer rate.
However, WEP proved to be inadequate and was easily hacked due to inherent flaws in the encryption methods. WPA2 is more secure than the other two and is much more efficient in terms of performance. Furnishes information RECIPIENTS SIDE: protection by counter mode with cipher block WEP utilizes five tasks to decrypt (IV+cipher text). It was a 40 bit encryption that used a RC4 stream cipher algorithm. is an encryption protocol included as part of the IEEE 802.11i standard for wireless LANs (WLANs). But even before I started being interested in having that cert just for shits and giggles, I've been part of the Auditor/BackTrack project from since it's inception. Figure 3 WPA Encryption Algorithm (TKIP) Figure 1: WEP encryption Sender side WPA2 (Wi-Fi protected Access 2) Implements totally IEEE 802.11 standard and improvement over WPA. To address the shortcomings of WEP security, a new security protocol was introduced called TKIP or the Temporal Key Integrity Protocol. I've got a CEH (Certified Ethical Hacker, seriously) cert now - and man that was easy to get. Unfortunately, it's all too easy to get into systems these days. WEP started off with 64-bit encryption and eventually went all the way up to 256-bit encryption, but the most popular implementation in routers was 128-bit encryption.
