Chapter 12 AP Profile Table 45 Configuration > Object > AP Profile > SSID > Security List > AAdd/Edit Security Profile> Security Mode: wpa2 (continued) LABEL DESCRIPTION Cipher Type Select an encryption cipher type from the list. Idle Timeout Group Key Update Timer Pre-Authentication Management Frame Protection • auto - This automatically chooses the best available cipher based on the cipher in use by the wireless client that is attempting to make a connection. • aes - This is the Advanced Encryption Standard encryption method. It is a more recent development over TKIP and considerably more robust. Not all wireless clients may support this. Enter the idle interval (in seconds) that a client can be idle before authentication is discontinued. Enter the interval (in seconds) at which the AP updates the group WPA2 encryption key. Select Enable to allow pre-authentication. Otherwise, select Disable. This field is available only when you select wpa2 in the Security Mode field and set Cipher Type to aes. Data frames in 802.11 WLANs can be encrypted and authenticated with WEP, WPA or WPA2. But 802.11 management frames, such as beacon/probe response, association request, association response, de-authentication and disassociation are always unauthenticated and unencrypted. IEEE 802.11w Protected Management Frames allows APs to use the existing security mechanisms (encryption and authentication methods defined in IEEE 802.11i WPA/WPA2) to protect management frames. This helps prevent wireless DoS attacks. Select the check box to enable management frame protection (MFP) to add security to 802.11 management frames. Select Optional if you do not require the wireless clients to support MFP. Management frames will be encrypted if the clients support MFP. OK Cancel Select Required and wireless clients must support MFP in order to join the Zyxel Device's wireless network. Click OK to save your changes back to the Zyxel Device.
