6.1.2.3 PSK / None


Configuring WLAN Security
Open-system authentication can be referred to as no authentication, since no actual authentication takes
place. A client requests (and is granted) authentication with no credential exchange.
NOTE: Although None implies no authentication, this option is also used when
pre-shared keys are used for encryption (thus the /PSK in the description).

6.1.2.4 Captive Portal


Configuring WLAN Security
A captive portal is guest access policy for providing guests temporary and restrictive access to the wireless
network. The primary means of securing such guest access is the use of a hotspot. For an overview of the
Captive Portal process and information on how to define a captive portal policy that can be applied to a
WLAN, see Configuring Captive Portal Policies on page

1. Select Configuration

6.1.2.5 WPA/WPA2-TKIP


Configuring WLAN Security
Wi-Fi Protected Access (WPA) is an encryption scheme specified in the IEEE Wireless Fidelity (Wi-Fi)
standard, 802.11i. WPA provides more sophisticated data encryption than WEP. WPA is designed for
corporate networks and small-business environments where more wireless traffic allows quicker discovery
of encryption keys by an unauthorized person.
The encryption method is Temporal Key Integrity Protocol (TKIP). TKIP addresses WEP's weaknesses with a
re-keying mechanism, a per-packet mixing function, a message integrity check, and an extended initialization
vector, however TKIP also has vulnerabilities.
