Figure 3-63. User Passwords Menu
To change the Administrator or Guest password, select the appropriate
menu item (A or B). A flashing cursor appears to the right. From here,
type the new password, which can be any alpha-numeric string up to 13
characters long. The change is asserted when you press the Return key.
• Change Admin Password —Allows you to set a new password.
[ any alpha-numeric string up to 13 characters; admin ]
• Change Guest Password —Allows you to set a new password.
[ any alpha-numeric string up to 13 characters; guest ]
TIP:
For enhanced security, consider using misspelled words, a combi-
nation of letters and numbers, and a combination of upper and
lower case letters. Also, the more characters used (up to 13), the
more secure the password. These strategies help protect against
sophisticated hackers who use a database of common words (for
example, dictionary attacks) to determine a password.
3.7.2 Wireless Security Menu
The features in the Wireless Security menu ( Figure 3-64 on Page 96 )
control the communication of data across the wireless link. You can
authenticate the radios locally via a list of authorized radios, or remotely
via a centralized IEEE 802.1x device authentication server. This server
provides a centralized authentication mechanism based on standards.
