Introduction

The Cisco Aironet Serieswireless freedom with enterprise-class security.

Perhaps the only thing more important to your business than the data exchanged on your network is the ability to maintain the security of that data. Security fears have caused some network managers to avoid installing wireless LANs (WLANs), regardless of the numerous benefits that they provide.

Now the landscape of wireless security has changed, giving IT managers the confidence to deploy WLANs. Today there's the Cisco Wireless Security Suitean enterprise-ready, standards-based, WLAN security solution for Cisco Aironet Series products and Cisco Compatible WLAN client devices.

Features of the Cisco Wireless Security Suite include:

  • Strong, mutual authentication and dynamic encryption key management via support for IEEE 802.1X
  • Data encryption using Temporal Key Integrity Protocol (TKIP), Wired Equivalent Privacy (WEP) and, in 2004,
  • Advanced Encryption Standard (AES)
  • Strong TKIP encryption enhancements such as message integrity check (MIC), per-packet keys via initialization vector hashing, and broadcast key rotation
  • Support for the broadest range of 802.1X authentication types, client devices, and client operating systems on the market
  • Mitigation of network attacks
  • Full support for the Wi-Fi Alliance security standard Wi-Fi Protected Access (WPA), introduced in 2003
    Cisco, the network leader and a driving force behind wireless networking, has made it possible for network managers to give users the freedom they crave without sacrificing the network security they demand.
