An advantage of the IEEE 802.11 standard for wireless networks is that it

gives a quick and easy way to connect your wireless station to a network.

For instance, wireless stations that have been configured with the network

name “ANY” will connect to the first IEEE 802.11 compatible Access Point

RLM it can find within range.

The drawback of this “quick & easy connectivity” is the vulnerability of the

LAN to unauthorized access. Does this mean that Wireless LANs are not

secure? The answer is no:

• Access to network resources is controlled via standard security

mechanisms, such as user names and passwords,

• The Siemens SIMATIC NET Industrial Wireless LAN products allow you

to apply additional security measures to restrict access to your wireless

medium and/or network resources.

Subject to the level of security required in your network environment, these

measures may include:

• Securing Access to Wireless Data (page 155).

• Wireless Data Encryption (page 167).

• Securing Access Point RLM Setup (page 177).

• Advanced Security Maintenance (page 183).
