Operating System Software
The operating system software controls Cisco Wireless LAN Controllers and Cisco 1000 Series
Lightweight Access Points. It includes full operating system security and Radio Resource Management
(RRM) features.
Operating System Security
Operating system security bundles Layer 1, Layer 2, and Layer 3 security components into a simple,
Cisco WLAN Solution-wide policy manager that creates independent security policies for each of up to
16 wireless LANs. (Refer to the “Cisco WLAN Solution Wireless LANs” section on page 1-11.)
The 802.11 Static WEP weaknesses can be overcome using robust industry-standard security solutions,
such as:
• 802.1X dynamic keys with extensible authentication protocol (EAP).
• Wi-Fi protected access (WPA) dynamic keys. The Cisco WLAN Solution WPA implementation
includes:
–
Temporal key integrity protocol (TKIP) + message integrity code checksum (Michael) dynamic
keys, or
–
WEP keys, with or without Pre-Shared key Passphrase.
