1.1.8.1 Kerberos Authentication
Authentication is a means of verifying information that is transmitted from a secure source. If
information is authentic, you know who created it and you know that it has not been altered in any
way since it was originated. Authentication entails a network administrator employing a software
“supplicant” on their computer or wireless device.
Authentication is critical for the security of any wireless LAN device. Traditional authentication
methods are not suitable for use in wireless networks where an unauthorized user can monitor
network traffic and intercept passwords. The use of strong authentication methods that do not
disclose passwords is necessary. Symbol uses the Kerberos authentication service protocol (specified
