Security
The following lists the types of security in a RoamAbout wireless environment:
•Network operating system security
•RoamAbout AP Secure Access
•Wired Equivalent Privacy (WEP) Encryption
•Simple Network Management Protocol (SNMP) community names
•SNMPv3 (RoamAbout R2 only)
•Device Authentication, which requires a RADIUS (Remote Authentication Dial-In
User Service) server. Authentication can be based on:
— MAC address
— 802.1X
— Both MAC address and 802.1X
•802.1X Rapid Rekeying
•Console port password
•Address Filtering (see “Filters” on page 2-21)

Network Operating System Security

To access networking data or services, a wireless client needs to run an appropriate network
operating system. Most network operating systems use standard security measures such as
login names and passwords. When you follow the standard network security procedures
and guidelines recommended for your network operating system, an unauthorized user
cannot access network data or services without the appropriate user name and password.
For detailed information, consult the documentation that came with the network operating
system or refer to the reseller of your LAN software.

RoamAbout AP Secure Access

When Secure Access is enabled, the AP denies access to wireless clients that do not use the
correct wireless network name. In addition, the AP does not broadcast its network name, so
that clients with operating systems like Windows XP do not see the name show up in
wireless LAN configuration dialogs.
When disabled, users can configure clients by leaving the network name field blank or
using ANY (all uppercase) as the wireless network name, and still connect to the network.
Clients will be able to view the network name in wireless LAN configuration dialogs.
