IoT Chip to Cloud Integration Blueprintĭid you know you can automate the management and renewal of every certificate?īy now, the risks of not securing your company’s Wi-Fi networks are well known and range from annoying (passersby mooching your free network and slowing down connections) to critical (unauthorized parties accessing your corporate information, eavesdropping on and intercepting sensitive information, capturing login credentials and spreading malware or viruses).įortunately, most companies have responded to these threats by securing their networks with WPA or WPA2, which encrypt data transmitted over the network and limit access only to authorized users (WPA2 is stronger, recommended for business and the term I’ll use from here out).

When he's not breaking wireless networks, he likes to work on his house, where he ends up breaking things of a different sort. Joshua Wright is a senior security researcher for Aruba Networks and an editorial board member of the WVE. While there have not been any catastrophic weaknesses reported in the TKIP protocol, organizations should take this design requirement into consideration and plan to transition WPA networks to WPA2 to take advantage of the benefits provided by the RSN architecture. It is important to note, however, that TKIP was designed as an interim solution for wireless security, with the goal of providing sufficient security for 5 years while organizations transitioned to the full IEEE 802.11i security mechanism. * Support for the CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) encryption mechanism based on the Advanced Encryption Standard (AES) cipher as an alternative to the TKIP protocol.Īs of March 2006, the WPA2 certification became mandatory for all new equipment certified by the Wi-Fi Alliance, ensuring that any reasonably modern hardware will support both WPA and WPA2.īy leveraging the RC4 cipher (also used in the WEP protocol), the IEEE 802.11i task group was able to improve the security of legacy networks with TKIP while the IEEE 802.11i amendment was completed. * Support for pre-authentication, where a station completes the IEEE 802.1X authentication exchange before roaming * Support for opportunistic key caching to reduce the overhead in roaming between access points * Reduced overhead in key derivation during the wireless LAN authentication exchange
