Configure a profile to have the wireless client automatically connect to a specific network or peer computer. This tutorial shows you how to manually connect to a network, and how to configure a profile.

2.1 Connecting to a Wireless LAN

This example illustrates how to manually connect your wireless client to an access point (AP) configured for WPA-PSK security. Before you connect to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared key. In this example, the AP°s SSID is “SSID_Example3” and its pre-shared key is “Thisismy WPA-PSKpre-sharedkey”. After you install the ZyXEL utility and then insert the wireless client, follow the steps below to connect to a network using the Site Survey screen. 1 Open the ZyXEL utility and click the Site Survey tab to open the screen shown next.

Wireless LAN Network This chapter provides background information on wireless LAN networks.

3.1 Wireless LAN Overview

The following figure provides an example of a wireless network with an AP. See Figure 3 on page 21 for an Ad Hoc network example. Figure 18 Example of a Wireless Network IL]

The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet Every wireless network must follow these basic guidelines. + Every device in the same wireless network must use the same SSID. The SSID is the name of the wireless network. It stands for Service Set IDentity. + _Iftwo wireless networks overlap, they should use a different channel. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.

Chapter 3 Wireless LAN Network 31

M-302 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. Configure the wireless LAN security using the Profile Security Settings screen. If you do not enable any wireless security on your M-302, the M-302’s wireless communications are accessible to any wireless networking device that is in the coverage area.See the appendices for more detailed information about wireless security.

3.2.1 User Authentication and Encryption

User authentication is when every user must log in to the wireless network before they can use it. However, every wireless client in the wireless network has to support IEEE 802.1x to do this. Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.

WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the M-302 and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption. There are two ways to create WEP keys in your M-302. + Automatic WEP key generation based on a “password phrase” called a passphrase. The passphrase is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN. For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the Security Settings screen of the ZyXEL utility and entering them manually as the WEP keys in the other WLAN adapter(s). Enter the WEP keys manually. Your M-302 allows you to configure up to four 64-bit, 128-bit or 256-bit WEP keys and only one key is used as the default key at any one time.

The IEEE 802.11b/g standard describes a simple authentication method between the wireless stations and AP. Three authentication types are defined: Auto, Open System and Shared Key. + 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 (WEP key). Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted. + Shared Key mode involves a shared secret key (WEP key) to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer. + Auto authentication mode allows the M-302 to switch between the open system and shared key modes automatically. Use the auto mode if you do not know the authentication mode of the other wireless stations.

The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server.

3.2.1.2.1 EAP Authentication

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. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x. The M-302 supports EAP-TLS, EAP-TTLS and EAP-PEAP. Refer to the appendix on wireless security for more details. For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called a digital ID) can be used to authenticate users, and a CA issues certificates and guarantees the identity of each certificate owner.

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. Refer to the appendix on wireless security for more details.

A profile is a set of wireless parameters that you need to connect to a wireless network. With a profile activated, each time you start the M-302 it automatically scans for the specific SSID and joins that network with the pre-defined wireless security settings. If the specified network is not available, the M-302 will remain disconnected. If you do not configure and activate a profile, each time you start the M-302 it uses the default profile to connect to any available network with security disabled. The default profile allows you to connect to any wireless network without security. Click the Profile tab in the ZyXEL utility program to display the Profile screen as shown next. The profile function allows you to save the wireless network settings in this screen, or use one of the pre-configured network profiles.

M-302 User's Guide The following table describes the labels in this screen. Table 16 Adapter Screen LABEL DESCRIPTION Adapter Setting Transfer Rate In most networking scenarios, the factory default Fully Auto setting is the most efficient and allows your M-302 to operate at the highest possible transfer (data) rate. If you want to select a specific transfer rate, select one that the AP or peer wireless device supports. Note: Super G The Super G technology works with IEEE 802.11 a/b/g products. lt doubles IEEE 802.11g performance by bonding two 54Mbps channels and allowing larger frames to be sent. Your M-302 can transmit at up to 108 Mbps when connected to an AP or wireless router with the Super G feature enabled. Preamble Type Preamble is used to signal that data is coming to the receiver. Select the preamble type that the AP uses. Short Preamble increases performance as less time sending preamble means more time for sending data. AIl IEEE 802.11b/g compliant wireless adapters support Long Preamble, but not all support short preamble. Select Auto to have the M-302 automatically use short preamble when all access point or wireless stations support it; otherwise the M-302 uses long preamble. Note: The M-302 and the access point or wireless stations MUST use the same preamble mode in order to communicate. Power Saving Mode Select Maximum Power Saving or Fast Power Saving to save power (especially for notebook computers). This forces the M-302 to go to sleep mode when it is not transmitting data. When you select Continuous Access Mode, the M-302 will never go to sleep mode. Save Click Save to save the changes back to the M-302.

M-302 Users Guide APPENDIX C Wireless Security 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. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x. For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called a digital ID) can be used to authenticate users, and a CA issues certificates and guarantees the identity of each certificate owner. EAP-MD5 (Message-Digest Algorithm 5) MDS authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless station. The wireless station ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MDS authentication method does not perform mutual authentication. Finally, MDS authentication method does not support data encryption with dynamic session key. You must configure WEP encryption keys for data encryption. Appendix C 73

M-302 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. This makes user identity vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the sender’s identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management overhead. EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2. PEAP (Protected EAP) LEAP Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MDS5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco. LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled. Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange

M-302 Users Guide WPA 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 29 Comparison of EAP Authentication Types

Mutual Authentication No Yes Yes Yes Yes Certificate — Client No Yes Optional Optional No Certificate — Server No Yes Yes Yes No Dynamic Key Exchange No Yes Yes Yes Yes Credential Integrity None Strong Strong Strong Moderate Deployment Difficulty Easy Hard Moderate Moderate | Moderate Client Identity Protection No No Yes Yes No Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. Key differences between WPA and WEP are improved data encryption and user authentication. Select WEP only when the AP and/or wireless clients do not support WPA. WEP is less secure than WPA. Encryption WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. 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 regularly changes and rotate the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless stations. This all happens in the background automatically. Appendix C

M-302 User's Guide The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped. By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), with TKIP and AES it is more difficult to decrypt data on a Wi-Fi network than WEP and difficult for an intruder to break into the network. 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 a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP) User Authentication WPA applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless stations using an external RADIUS database. WPA-PSK Application Example A WPA-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. 3 The AP and wireless clients use the pre-shared key to generate a common PMK. 4 The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them. 76 Appendix C

WPA 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 application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system. 1 The AP passes the wireless client's authentication request to the RADIUS server. 2 The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly. 3 The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.
