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
