# Create Profiles for Windows*

This section describes how to create profiles for Windows* XP, Windows Vista*, and Windows* 7.

An infrastructure network consists of one or more access points and one or more computers with WiFi adapters installed. Each access point must have a wired connection to a WiFi network. This section describes how to create various WiFi profiles.

NOTE: Several limitations apply to single sign-on profiles created for Windows Vista* and Windows* 7 clients. See Single Sign-on Considerations for Windows Vista* and Windows* 7.

- Create a Profile with No Authentication or Data Encryption
- Create a Profile with Shared Network Authentication
- Create a Profile with WPA-Personal or WPA2-Personal Network Authentication
- Create a Profile with WPA-Enterprise or WPA2-Enterprise Network Authentication
- Create a Profile with WEP Data Encryption and EAP-SIM Network Authentication
- Create a Profile with TLS Network Authentication
- Create a Profile with TTLS Network Authentication
- Create a Profile with PEAP Network Authentication
- Create a Profile with LEAP Network Authentication
- Create a Profile with EAP-AKA Network Authentication
- Create a Profile with EAP-FAST Network Authentication

## Create a Profile with No Authentication or Data Encryption (None)

CAUTION: Networks using no authentication or encryption are highly vulnerable to access by unauthorized users.

To create a profile for a WiFi network connection with no encryption:

1. Click Profiles... on the Intel® PROSet/Wireless WiFi Connection Utility main window. Or if you are acting as the administrator, open the Administrator Tool.
2. On the Profiles list/tab, click Add to open the Create WiFi Profile General Settings.
3. Profile Name: Enter a descriptive profile name.
4. WiFi Network Name (SSID): Enter the network identifier.
5. Operating Mode: Click Network (Infrastructure). (This parameter is set to Infrastructure if you are using the Administrator Tool.)
6. Administrator Profile Type: Select Persistent or Pre-logon/Common. (This step applies only if you are using the Administrator Tool.)
7. Click Next to open the Security Settings.
8. Click Enterprise Security.
9. Network Authentication: Open (Selected).

> Open authentication allows a wireless device access to the network without 802.11 authentication. If no encryption is enabled on the network, any wireless device with the correct network name (SSID) can associate with an access point and gain access to the network.

10. Data Encryption: None is the default.
11. Click OK. The profile is added to the Profiles list and connects to the wireless network.

## Create a Profile with Shared Network Authentication

When shared key authentication is used, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel. Shared key authentication requires that the client configure a static WEP or CKIP key. The client access is granted only if it passes a challenge-based authentication. CKIP provides stronger data encryption than WEP, but not all operating systems and access points support it.

NOTE: While shared key would appear to be the better option for a higher level of security, a known weakness is created by the clear text transmission of the challenge string to the client. If someone uses a software tool to detect the challenge string, the shared authentication key can be easily reverse-engineered. Therefore, open authentication (with data encryption) is actually more secure.

To create a profile with shared authentication:

1. Click Profiles... on the WiFi connection utility main window. Or if you are acting as the administrator, open the Administrator Tool.
2. On the Profiles list/tab, click Add to open the Create WiFi Profile General Settings.
3. Profile Name: Enter a descriptive profile name.
4. WiFi Network Name (SSID): Enter the network identifier.
5. Operating Mode: Click Network (Infrastructure). (This parameter is set to Infrastructure if you are using the Administrator Tool.)
6. Administrator Profile Type: Select Persistent or Pre-logon/Common. (This step applies only if you are using the Administrator Tool.)
7. Click Next to open the Security Settings.
8. Click Enterprise Security.
9. Network Authentication: Select Shared. Shared authentication is accomplished with a pre-configured WEP key.
10. Data Encryption: Select None, WEP (64-bit or 128-bit), or CKIP (64-bit or 128-bit).
11. Enable 802.1X: Disabled.
12. Encryption Level: 64-bit or 128-bit: When switching between 64-bit and 128-bit encryption, the previous settings are erased and a new key must be entered.
13. Key Index: Select 1, 2, 3, or 4. Change the Key Index to specify up to four passwords.
14. Wireless Security Password (Encryption Key): Enter the wireless network password (Encryption Key). This password is the same value used by the wireless access point or router. Contact your administrator for this password.

- Pass phrase (64-bit): Enter five (5) alphanumeric characters, 0-9, a-z or A-Z.
- Hex key (64-bit): Enter 10 hexadecimal characters, 0-9, A-F.
- Pass phrase (128-bit): Enter 13 alphanumeric characters, 0-9, a-z or A-Z.
- Hex key (128-bit): Enter 26 hexadecimal characters, 0-9, A-F.

## Create a Profile with WPA-Personal or WPA2-Personal Network Authentication

Wi-Fi Protected Access (WPA) is a security enhancement that strongly increases the level of data protection and access control to a wireless network. WPA-Personal enforces key-exchange and only works with dynamic encryption keys. If your wireless access point or router supports WPA-Personal or WPA2-Personal, then you should enable it on the access point and provide a long, strong password. For personal or home networks without a RADIUS or AAA server, use Wi-Fi Protected Access Personal.

- WPA-Personal: A wireless security method that provides strong data protection and prevents unauthorized network access for small networks. It uses Temporal Key Integrity Protocol (TKIP) or AES-CCMP encryption and protects against unauthorized network access through the use of a pre-shared key (PSK).
- WPA2-Personal: A follow-on wireless security method to WPA that provides stronger data protection and prevents unauthorized network access for small networks.

NOTE: WPA-Personal and WPA2-Personal are interoperable.

Some security solutions may not be supported by your computer's operating system and may require additional software or certain hardware as well as wireless LAN infrastructure support. Check with your computer manufacturer for details.

To add a profile with WPA-Personal or WPA2-Personal network authentication:

1. Click Profiles... on the WiFi connection utility main window. Or if you are acting as the administrator, open the Administrator Tool.
2. On the Profiles list/tab, click Add to open the Create WiFi Profile General Settings.
3. Profile Name: Enter a descriptive profile name.
4. WiFi Network Name (SSID): Enter the network identifier.
5. Operating Mode: Click Network (Infrastructure). (This parameter is set to Infrastructure if you are using the Administrator Tool.)

7. Click Next to open the Security Settings.
8. Click Enterprise Security.
9. Network Authentication: Select WPA-Personal or WPA2-Personal. See Security Overview.
10. Data Encryption: Select either TKIP or AES-CCMP.
11. Password: Enter a text phrase from 8 to 63 characters. A long password provides stronger network security than a short password. The same password entered into an access points needs to be used on this computer and all other wireless devices that access the wireless network.

## Create a Profile with WPA-Enterprise or WPA2-Enterprise Network Authentication

WPA2-Enterprise requires an authentication server.

- WPA-Enterprise: A wireless security method that provides strong data protection for multiple users and large managed networks. It uses the 802.1X authentication framework with TKIP or AES-CCMP encryption and prevents unauthorized network access by verifying network users through an authentication server.
- WPA2-Enterprise: The follow-on wireless security method to WPA that provides stronger data protection for multiple users and large managed networks. It prevents unauthorized network access by verifying network users through an authentication server.

NOTE: WPA-Enterprise and WPA2-Enterprise are interoperable.

To add a profile that uses WPA-Enterprise or WPA2-Enterprise authentication:

1. Obtain a user name and password on the RADIUS server from your administrator.
2. Certain Authentication Types require that you obtain and install a client certificate. See Create a Profile with TLS authentication or consult your administrator.
3. Click Profiles... on the WiFi connection utility main window. Or if you are acting as the administrator, open the Administrator Tool.
4. On the Profiles list, click Add to open the Create WiFi Profile General Settings.

## Create a Profile with TTLS Network Authentication

TTLS authentication: These settings define the protocol and credentials used to authenticate a user. The client uses EAP-TLS to validate the server and create a TLS-encrypted channel between the client and server. The client can use another authentication protocol. Typically, password-based protocols challenge over a non-exposed TLS encrypted channel.

### Profile Mapping

This profile will be exported differently to clients running Windows* XP as compared to Windows Vista* and Windows* 7. See TTLS Profile Mapping for more information.

### To Create a Profile with TTLS Authentication

1. Click Profiles... on the WiFi connection utility main window. Or if you are acting as the administrator, open the Administrator Tool.
2. On the Profiles list, click Add to open the Create WiFi Profile General Settings.
3. Profile Name: Enter a descriptive profile name.

#### Step 1 of 2: TTLS User

1. Authentication Protocol: This parameter specifies the authentication protocol operating over the TTLS tunnel. The protocols are: PAP (Default), CHAP, MS-CHAP and MS-CHAP-V2. See Security Overview for more information.
2. User Credentials: For PAP, CHAP, MS-CHAP, and MS-CHAP-V2 protocols, select one of these authentication methods: Use Windows logon, Prompt each time I connect, or Use the following.
3. Roaming Identity: A Roaming Identity may be populated in this field or you can use %domain%\%username% as the default format for entering a roaming identity.

> When 802.1X Microsoft IAS RADIUS is used as an authentication server, the server authenticates the device using the Roaming Identity from Intel® PROSet/Wireless WiFi Software, and ignores the Authentication Protocol MS-CHAP-V2 user name. Microsoft IAS RADIUS accepts only a valid user name (dotNet user) for the Roaming Identity. For all other authentication servers, the Roaming Identity is optional. Therefore, it is recommended to use the desired realm (for example, anonymous@myrealm) for the Roaming Identity rather than a true identity.

4. Click Next to access the TTLS Server settings.

#### Step 2 of 2: TTLS Server

1. Select one of the following credential retrieval methods: Validate Server Certificate or Specify Server or Certificate Name.
2. Click OK to save the setting and close the page.

## Create a Profile with PEAP Network Authentication

PEAP authentication: PEAP settings are required for the authentication of the client to the authentication server. The client uses EAP-TLS to validate the server and create a TLS-encrypted channel between client and server. The client can use another EAP mechanism, such as Microsoft Challenge Authentication Protocol (MS-CHAP) Version 2, over this encrypted channel to enable server validation. The challenge and response packets are sent over a non-exposed TLS encrypted channel. The following example describes how to use WPA with AES-CCMP or TKIP encryption with PEAP authentication.

### Profile Mapping

This profile will be exported differently to clients running Windows* XP as compared to Windows Vista* and Windows* 7. See PEAP Profile Mapping for more information.

### To Create a Profile with PEAP Authentication

Obtain and install a client certificate. See Create a Windows* XP Profile for TLS authentication or consult your administrator.

1. Click Profiles... on the WiFi connection utility main window. Or if you are acting as the administrator, open the Administrator Tool.
2. On the Profiles list, click Add to open the Create WiFi Profile General Settings.
3. Profile Name: Enter a descriptive profile name.
4. WiFi Network Name (SSID): Enter the network identifier.
5. Operating Mode: Click Network (Infrastructure). (This parameter is set to Infrastructure if you are using the Administrator Tool.)
6. Administrator Profile Type: Select Persistent or Pre-logon/Common. (This step applies only if you are using the Administrator Tool.
7. Click Next to open the Security Settings.
8. Click Enterprise Security.
9. Network Authentication: Select WPA-Enterprise or WPA2-Enterprise (Recommended).
10. Data Encryption: Select one of the following: AES-CCMP is recommended.
11. Enable 802.1X: Selected by default.
12. Authentication Type: Select PEAP to be used with this connection.

#### Step 1 of 2: PEAP User

PEAP relies on Transport Layer Security (TLS) to allow unencrypted authentication types such as EAP-Generic Token Card (GTC) and One-Time Password (OTP) support.

1. Authentication Protocol: Select either GTC, MS-CHAP-V2 (Default), or TLS. See Authentication Protocols.
2. User Credentials: Following are available options for User Credentials. The available credentials may not match those listed here, depending on whether you are creating a profile on Windows* XP, or are creating an IT Administrator profile for Windows XP, Windows Vista, or Windows* 7. More information is provided later in this section.
   - For GTC, User Credentials can be set to Use Windows logon, or Prompt each time I connect or Use the following, (which requires the Use Name, Domain, and Password). Available options will also differ depending on this whether is a Persistent or non-Persistent profile (selected on the General Settings window for Administrator profiles).
   - For MS-CHAP-V2, User Credentials can be set to Use Windows logon, or Prompt each time I connect or Use the following, (which requires the Use Name, Domain, and Password). Available options will also differ depending on this whether is a Persistent or non-Persistent profile (selected on the General Settings window for Administrator profiles). For Persistent IT Administrator profiles, you can set User Credentials to Use the following or Use secured password. The secured password uses machine credentials and is not tied to any specific user.
   - For TLS, for a single user profile in Windows* XP, User Credentials can be set to Use Windows logon, or Prompt each time I connect or Use the following, (which requires the Use Name, Domain, and Password). For non-persistent administrator profiles, (deselected on the General Settings window), you can choose one of the following: Use my smart card, Use the certificate issued to this computer, or Use a user certificate on this computer. For Persistent IT Administrator profiles, User Credentials can be set to Use the certificate issued to this computer.
3. Roaming Identity: A Roaming Identity may be populated in this field or you can use %domain%\%username% as the default format for entering a roaming identity.

> When 802.1X Microsoft IAS RADIUS is used as an authentication server, the server authenticates the device using the Roaming Identity from Intel® PROSet/Wireless WiFi Software, and ignores the Authentication Protocol MS-CHAP-V2 user name. Microsoft IAS RADIUS accepts only a valid user name (dotNet user) for the Roaming Identity. For all other authentication servers, the Roaming Identity is optional. Therefore, it is recommended to use the desired realm (for example, anonymous@myrealm) for the Roaming Identity rather than a true identity.

> #### Configure Roaming Identity to Support Multiple Users:

> If you use a Pre-logon/Common profile that requires the roaming identity to be based on the Windows logon credentials, the creator of the profile can add a roaming identity that uses %username% and %domain%. The roaming identity is parsed and the appropriate log on information is substituted for the keywords. This allows maximum flexibility in configuring the roaming identity while allowing multiple users to share the profile.

> Please see your authentication server user guide for directions about how to format a suitable roaming identity. Possible formats are:

> %domain%\%user_name%
> %user_name%@%domain%
> %user_name%@%domain%.com
> %user_name%@mynetwork.com

> If Roaming Identity is blank, %domain%\%username% is the default.

> Notes about the credentials: This user name and domain must match the user name that is set in the authentication server by the administrator prior to client authentication. The user name is case-sensitive. This name specifies the identity supplied to the authenticator by the authentication protocol operating over the TLS tunnel. This user identity is securely transmitted to the server only after an encrypted channel has been verified and established.

#### Authentication Protocols

This parameter specifies the authentication protocols that can operate over the TTLS tunnel. Next are instructions on how to configure a profile that uses PEAP authentication with GTC, MS-CHAP-V2 (Default), or TLS authentication protocols. The User Credentials selected are examples.

6. Administrator Profile Type: Select Persistent or Pre-logon/Common. (This step applies only if you are using the Administrator Tool.
7. Click Next to open the Security Settings.
8. Click Enterprise Security.
9. Network Authentication: Select WPA-Enterprise or WPA2-Enterprise (Recommended).
10. Data Encryption: AES-CCMP is recommended.
11. Enable 802.1X: Selected.
12. Authentication Type: Select EAP-FAST to be used with this connection.

Step 1 of 3: EAP-FAST Provisioning

With CCXv4, EAP-FAST supports two modes for provisioning:

- Server-Authenticated Mode: Provisioning inside a server authenticated TLS tunnel.
- Server-Unauthenticated Mode: Provisioning inside an unauthenticated TLS tunnel.

NOTE: Server-Authenticated Mode provides significant security advantages over Server-Unauthenticated Mode even when EAP-MS-CHAP-V2 is being used as an inner method. This mode protects the EAP-MS-CHAP-V2 exchanges from potential Man-in-the-Middle attacks by verifying the server’s authenticity before exchanging MS-CHAP-V2. Therefore, Server-Authenticated Mode is preferred whenever it is possible. EAP-FAST peer must use Server-Authenticated Mode whenever a certificate or public key is available to authenticate the server and ensure the best security practices.

Provisioning of Protected Access Credentials (PAC):

EAP-FAST uses a PAC key to protect the user credentials that are exchanged. All EAP-FAST authenticators are identified by an authority identity (A-ID). The local authenticator sends its A-ID to an authenticating client, and the client checks its database for a matching A-ID. If the client does not recognize the A-ID, it requests a new PAC.

NOTE: If the provisioned Protected Access Credential (PAC) is valid, the WiFi connection utility does not prompt the user for acceptance of the PAC. If the PAC is invalid, the WiFi connection utility fails the provisioning automatically. A status message is displayed in the Wireless Event Viewer that an administrator can review on the user's computer.

1. Verify that Disable EAP-FAST Enhancements (CCXv4) is not selected. Allow unauthenticated provisioning and Allow authenticated provisioning are selected by default. Once a PAC is selected from the Default Server, you can deselect any of these provisioning methods.
2. Default Server: None is selected as the default. Click Select Server to select a PAC from the default PAC authority server or select a server from the Server group list. The EAP-FAST Default Server (PAC Authority) selection page opens.

> NOTE: Server groups are only listed if you have installed an Administrator Package that contains EAP-FAST Authority ID (A-ID) Group settings.

> PAC distribution can also be completed manually (out-of-band). Manual provisioning enables you to create a PAC for a user on an ACS server and then import it into a user's computer. A PAC file can be protected with a password, which the user needs to enter during a PAC import.

3. To import a PAC:
   1. Click Import to import a PAC from the PAC server.
   2. Click Open.
   3. Enter the PAC password (optional).
   4. Click OK closes this page. The selected PAC is used for this wireless profile.

EAP-FAST CCXv4 enables support for the provisioning of other credentials beyond the PAC currently provisioned for tunnel establishment. The credential types supported include trusted CA certificate, machine credentials for machine authentication, and temporary user credentials used to bypass user authentication.

#### Use a certificate (TLS Authentication)

1. Click Use a certificate (TLS Authentication)
2. Click Identity Protection when the tunnel is protected.
3. Select one of the following to obtain a certificate: Use my smart card, Use the certificate issued to this computer, or Use a user certificate on this computer.
4. User Name: Enter the user name assigned to the user certificate.
5. Click Next.

#### Step 2 of 3: EAP-FAST Additional Information

If you selected Use a certificate (TLS Authentication) and Use a user certificate on this computer, click Next (no roaming identity is required) and proceed to Step 3 to configure EAP-FAST Server certificate settings. If you do not need to configure EAP-FAST server settings, click OK to save your settings and return to the Profiles page.

If you selected to Use my smart card, add the roaming identity, if required. Click OK to save your settings and return to the Profiles page.

If you did not select Use a certificate (TLS Authentication), click Next to select an Authentication Protocol. CCXv4 permits additional credentials or TLS cipher suites to establish the tunnel.

Authentication Protocol: Select either GTC, or MS-CHAP-V2 (Default).

Generic Token Card (GTC)

GTC may be used with Server-Authenticated Mode. This enable peers using other user databases as Lightweight Directory Access Protocol (LDAP) and one-time password (OTP) technology to be provisioned in-band. However, the replacement may only be achieved when used with the TLS cipher suites that ensure server authentication.

To configure a one-time password:

1. Authentication Protocol: Select GTC (Generic Token Card).
2. User Credentials: Select Prompt each time I connect.
3. On connection prompt for: Select one of the following:

> Name | Description
> --- | ---
> Static Password | On connection, enter the user credentials.
> One-time password (OTP) | Obtain the password from a hardware token device.
> PIN (Soft Token) | Obtain the password from a soft token program.

4. Click OK.
5. Select the profile on the WiFi Networks list.
6. Click Connect. When prompted, enter the user name, domain and one-time password (OTP).
7. Click OK.

MS-CHAP-V2. This parameter specifies the authentication protocol operating over the PEAP tunnel.

1. Authentication Protocol: Select MS-CHAP-V2.
2. Select the user credentials: Use Windows logon, Prompt each time I connect, or Use the following.
3. Roaming Identity: A Roaming Identity may be populated in this field or you can use %domain%\%username% as the default format for entering a roaming identity.

> When 802.1X Microsoft IAS RADIUS is used as an authentication server, the server authenticates the device using the Roaming Identity from Intel® PROSet/Wireless WiFi Software, and ignores the Authentication Protocol MS-CHAP-V2 user name. Microsoft IAS RADIUS accepts only a valid user name (dotNet user) for the Roaming Identity. For all other authentication servers, the Roaming Identity is optional. Therefore, it is recommended to use the desired realm (for example, anonymous@myrealm) for the Roaming Identity rather than a true identity.

#### Step 3 of 3: EAP-FAST Server

Authenticated-TLS-Server Provisioning Mode is supported using a trusted CA certificate, a self-signed server certificate, or server public keys and GTC as the inner EAP method.

1. Select one of the following credential retrieval methods: Validate Server Certificate or Specify Server or Certificate Name.
2. Click OK to close the security settings.

### EAP-FAST User Settings

NOTE: If an Administrator Package to be exported to a user's computer does not include the Enable CCXv4 Administrator Tool Application Setting, only EAP-FAST User Settings will be available for configuration.

To set up a client with EAP-FAST authentication:

1. Click Profiles... on the WiFi connection utility main window. Or if you are acting as the administrator, open the Administrator Tool.
2. On the Profile page, click Add to open the Create WiFi Profile General Settings.

7. Click Next to open the Security Settings.
8. Click Enterprise Security.
9. Network Authentication: Select WPA-Enterprise or WPA2-Enterprise.
10. Data Encryption: Select one of the following:
    - TKIP provides per-packet key mixing, a message integrity check and a rekeying mechanism.
    - AES-CCMP (Advanced Encryption Standard - Counter CBC-MAC Protocol) is used as the data encryption method whenever strong data protection is important. AES-CCMP is recommended.
11. Enable 802.1X: Selected.
12. Authentication Type: Select EAP-FAST to be used with this connection.
13. Click Cisco Options to select Allow Fast Roaming (CCKM), which enables the client WiFi adapter for fast secure roaming.

#### Step 1 of 3: EAP-FAST Provisioning (User Settings)

EAP-FAST uses a PAC key to protect the user credentials that are exchanged. All EAP-FAST authenticators are identified by an authority identity (A-ID). The local authenticator sends its A-ID to an authenticating client, and the client checks its database for a matching A-ID. If the client does not recognize the A-ID, it requests a new PAC.

NOTE: If the provisioned Protected Access Credential (PAC) is valid, the WiFi connection utility does not prompt the user for acceptance of the PAC. If the PAC is invalid, the WiFi connection utility fails the provisioning automatically. A status message is displayed in the Wireless Event Viewer that an administrator can review on the user's computer.

1. Leave unchecked Disable EAP-FAST Enhancements (CCXv4).
2. Allow authenticated provisioning and Allow unauthenticated provisioning are both checked.
3. Default Server: None selected is the default. Click Select Server to select a PAC from the default PAC authority server. The Protected Access Credentials selection page opens.
