Layer 2 Solutions

Layer 2 Solutions

If a higher level of security and encryption is required, the network administrator can also implement
industry-standard security solutions, such as: 802.1X dynamic keys with EAP (extended authorization
protocol), or WPA (Wi-Fi protected access) dynamic keys. The Airespace WPA implementation includes
AES (advanced encryption standard), TKIP + Michael (temporal key integrity pr message
integrity code checksum) dynamic keys, or WEP (Wired Equivalent Privacy) static keys. Blacklisting is
also used to automatically block Layer 2 access after an operator-set number of failed authentication
attempts.
