Viewing the Current Status of Your Client Adapter
Using Message Integrity
Check
Indicates whether your client adapter is using message integrity check
(MIC) to protect packets sent to and received from the access point.
MIC prevents bit-flip attacks on encrypted packets. During a bit-flip
attack, an intruder intercepts an encrypted message, alters it slightly,
and retransmits it, and the receiver accepts the retransmitted message
as legitimate.
Note MIC is supported automatically by the client adapter’s driver,
but it must be enabled on the access point.
Value: Yes or No
Server Based Authentication Indicates the configuration of the access point to which your client
adapter is associated.
Value: None, WEP Key In Use, Cell Is Secure, or LEAP
Authenticated
Server Based Authentication Description
None The access point is configured for No
Encryption.
WEP Key In Use The access point is configured for
Optional encryption.
Cell Is Secure The access point is configured for Full
Encryption.
Note If the client’s current profile does
not have Allow Association to
Mixed Cells enabled, the client
can associate only to access points
that use full encryption.
LEAP Authenticated The client is using LEAP and is
authenticated to an access point that has
WEP and Network-EAP enabled.
WEP (Wired Equivalent
Privacy)
Your client adapter’s current WEP status.
Value: Enabled, Not Enabled, or Need Firmware Upgrade
Note Refer to the “Setting Network Security Parameters” section on
page 5-20 for information on enabling WEP.
Authentication Type Indicates whether the client adapter must share the same WEP keys as
the access point in order to communicate or can communicate with the
access point regardless of its WEP settings.
Value: Open or Shared Key
Note Refer to the “Setting Network Security Parameters” section on
page 5-20 for information on setting the authentication type.
