Enablers:

• Increasing demand by corporate consumers
• Increasing attention of research on the 802.11 standard
• Increased support by major industry leaders - e.g. Intel, Apple
• Increasing number of e-crimes
• Increasing use of Internet

Inhibitors:

• Backward compatibility had to be retained
• Hardware manufacturers' products had to be compatible

Paradigms:

Emerging paradigms associated with the emergence of WPA security:

• Increases in Wardriving are fueling fears that security vulnerabilties will be exploited and there will be increased opportunity for attacks
• Laptops are increasingly being delivered with WiFi as standard, and open to attack without users even realising
• Poor knowledge of security techniques and consumer desire to 'roam' between sites (without knowing security settings) is increasing scope for attacks

Experts:

• IEEE - http://www.ieee.org
• Intel - http://www.intel.org

Timing:

• Original IEEE 802.11 standard established in 1997 - Used WEP security
• By 2001 research had shown major flaws with the WEP standard available
• In 2003, the 802.11 consortium expedited the release of 802.11i security - i.e. WPA
• In 2004 802.11i was ratified and with it WPA2 was established
