Preventing Unauthorized Access to Your Access Point
Preventing Unauthorized Access to Your Access Point
You can prevent unauthorized users from reconfiguring the wireless device and viewing configuration
information. Typically, the network administrators must have access to the wireless device while
restricting access to users who connect through a terminal or workstation from within the local network.
To prevent unauthorized access to the wireless device, configure one of these security features:
•
Username and password pairs, which are locally stored on the wireless device. These pairs
authenticate each user before the user can access the wireless device. You can also assign a specific
privilege level (read only or read/write) to each username and password pair. For more information,
see the
“Configuring Username and Password Pairs” section on page 301
. The default username is
Cisco
, and the default password is
Cisco
. Usernames and passwords are case sensitive.
Note
The characters TAB, ?, $, +, and [ are invalid characters for passwords.
•
Username and password pairs are stored centrally in a database on a security server. For more
information, see the
“Controlling Access Point Access with RADIUS” section on page 305
.
Protecting Access to Privileged EXEC Commands
A simple way of providing terminal access control in your network is to use passwords and assign
privilege levels. Password protection restricts access to a network or network device. Privilege levels
define what commands users can issue after they have logged in to a network device.
Note
For complete syntax and usage information for the commands used in this section, see

Security Command Reference for Release 12.4
