  • Page 36: Wireless Lan Security

    ZyXEL AG-220 User’s Guide • Every device in the same wireless network must use security compatible with the AP or peer computer. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. 3.2 Wireless LAN Security Wireless LAN security is vital to your network to protect wireless communications.

  • Page 37: User Authentication And Encryption

    You can use the MAC address filter to tell the AG-220 in AP mode which devices are allowed or not allowed to use the wireless network. If a device is allowed to use the wireless network, it still has to have the correct information (SSID, channel, and security). If a device is not allowed to use the wireless network, it does not matter if it has the correct information.

  • Page 38: Ieee 802.1X

    ZyXEL AG-220 User’s Guide • Open System mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP or peer computer do not share a secret key. Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted.

  • Page 39: Introduction To Otist

    If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client.

  • Page 40: Wireless Client

    ZyXEL AG-220 User’s Guide In the web configurator, go to the Wireless LAN main screen and then select OTIST. To change the Setup key, enter zero to eight printable characters. To have OTIST automatically generate a WPA-PSK key, select the Yes! check box. If you manually configured a WEP key or a WPA-PSK key and you also selected this check box, then the key you manually configured is used.

    1 In the AP, a web configurator screen pops up showing you the security settings to transfer. After reviewing the settings, click 2 This screen appears while OTIST settings are being transferred. It closes when the transfer is complete. • In the wireless client, you see this screen if it can't find an OTIST-enabled AP (with the same Setup key).
  • Page 42 ZyXEL AG-220 User’s Guide 5 If you configure OTIST to generate a WPA-PSK key, this key changes each time you run OTIST. Therefore, if a new wireless client joins your wireless network, you need to run OTIST on the AP and ALL the wireless clients again. Chapter 3 Wireless LAN Network...

    Types of EAP Authentication This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. Your wireless LAN device may not support all authentication types. EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication.

  • Page 92: Dynamic Wep Key Exchange

    ZyXEL AG-220 User’s Guide EAP-TLS (Transport Layer Security) With EAP-TLS, digital certifications are needed by both the server and the wireless stations for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created.

  • Page 93: Table 34 Comparison Of Eap Authentication Types

    For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types. Table 34 Comparison of EAP Authentication Types Mutual Authentication Certificate –...

  • Page 94: User Authentication

    ZyXEL AG-220 User’s Guide TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server. AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael. They both include a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism.

    WPA(2)-PSK Application Example A WPA(2)s-PSK application looks as follows. 1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and symbols). 2 The AP checks each client's password and (only) allows it to join the network if it matches its password.
