What is Wi-Fi Protected Access 2(WPA2)?

An improved version of WPA, known as WPA2, was released in 2004. The latest version of the Wi-Fi-protected access wireless security protocol is called WPA2(Wi-Fi-protected access 2). Similar to WPA1, WPA2 was created with Wi-Fi network security and protection in mind. Only those who possess your network password can access the encrypted data that is broadcast or received over your wireless network to WPA2. 

The advanced encryption system(AES) was introduced by the WPA2 system as a benefit, taking the place of the more susceptible TKIP system in the original WPA protocol. AES offers robust encryption which is used by the US government to safeguard confidential information. WPA2 has gained widespread acceptance and is regarded as the industry standard for protecting wireless networks. WPA2 is used by most routers and Wi-Fi networks. 

Pros of WPA2

  • Addresses many security flaws of its predecessors
  • Use the strongest encryption method -AES
  • The 256-bit key for encryption
  • Required by the Wi-Fi alliance for use on all wi-fi certified products
Cons of WPA2
  • Still continues some security vulnerabilities
  • Requires the most processing power
