    This chapter discusses how to configure wireless security on the G-360. Wireless LAN Security Wireless LAN security is vital to protect wireless communications. The figure below shows the possible wireless security levels on your G-360. EAP (Extensible Authentication Protocol) is used for authentication and utilizes dynamic WEP key exchange. It requires interaction with a RADIUS (Remote Authentication Dial-In User Service) server either on the WAN or your LAN to provide authentication service for wireless clients.

  • Page 47: Chapter 6 Adapter

    ZyXEL G-360 User’s Guide Chapter 6 Adapter This chapter discusses OTIST and how to configure the Adapter screen. Introduction to OTIST In a wireless network, the wireless clients must have the same SSID and security settings as the access point (AP) or wireless router (we will refer to both as “AP” here) in order to associate with it. Traditionally this meant that you have to configure the settings on the AP and then manually configure the exact same settings on each wireless client.

  • Page 48: Starting Otist

    ZyXEL G-360 User’s Guide You can enable OTIST using the reset button or the web configurator. If you use the reset button, the default (01234567) or previous saved (through the web configurator) Setup Key is used to encrypt the settings that you want to transfer. Hold in the Reset button for one or two seconds.

  • Page 49: Notes On Otist

    In the wireless client, you see this screen if it can't find an OTIST-enabled AP (with the same Setup Key). Click OK to go back to the ZyXEL Utility main screen. If there is more than one OTIST-enabled AP within range, you see a screen asking you to select one AP to get settings from.

  • Page 50: Configuring The Adapter Screen

    ZyXEL G-360 User’s Guide 4. If you change the SSID or the keys on the AP after using OTIST, you need to run OTIST again or enter them manually in the wireless client(s). 5. If you configure OTIST to generate a WPA(2)-PSK key, this key changes each time you run OTIST.

Ad-Hoc (IBSS) The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless clients. Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an Ad-hoc network or Independent Basic Service Set (IBSS).
  • Page 86 ZyXEL G-360 User’s Guide Diagram 25 BSS Example A series of overlapping BSS and a network medium, such as an Ethernet forms an Extended Service Set (ESS) or infrastructure network. All communication is done through the AP, which relays data packets to other wireless clients or devices connected to the wired network.
  • Page 87 ZyXEL G-360 User’s Guide EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless client and a RADIUS server perform authentication.
  • Page 88 ZyXEL G-360 User’s Guide The encryption mechanisms used for WPA and WPA-PSK are the same. The only difference between the two is that WPA-PSK uses a simple common password, instead of user-specific credentials. The common- password approach makes WPA-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs an easier-to-use, consistent, single, alphanumeric password.
  • Page 89 WPA(2) with RADIUS Application Example You need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. “A” is the RADIUS server.

  • Page 91: Appendix E Types Of Eap Authentication

    This appendix discusses the five popular EAP authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. The type of authentication you use depends on the RADIUS server. Consult your network administrator for more information. EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless client.
  • Page 92 ZyXEL G-360 User’s Guide LEAP LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE802.1x. 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.
