Personal Security Settings Description

Set up Data Encryption and Authentication

In a home wireless network you can use a variety of simple security procedures to protect your wireless connection. These include:

• Enable Wi-Fi Protected Access* (WPA).
• Change your password.
• Change the network name (SSID).

Wi-Fi Protected Access (WPA) encryption provides protection for your data on the network. WPA uses an encryption key called a Pre-Shared Key (PSK) to encrypt data before transmission. Enter the same password in all of the computers and access point in your home or small business network. Only devices that use the same encryption key can access the network or decrypt the encrypted data transmitted by other computers. The password automatically initiates the Temporal Key Integrity Protocol (TKIP) or AES-CCMP protocol for the data encryption process.

Network Keys

WEP encryption provides two levels of security:

• 64-bit key (sometimes referred to as 40-bit)
• 128-bit key (also known as 104-bit)

For improved security, use a 128-bit key. If you use encryption, all wireless devices on your wireless network must use the same encryption keys.

You can create the key yourself and specify the key length (64-bit or 128-bit) and key index (the location that a specific key is stored). The greater the key length, the more secure the key.

Key Length: 64-bit

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.

Key Length: 128-bit

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.

With WEP data encryption, wireless station can be configured with up to four keys (the key index values are 1, 2, 3, and 4). When an access point or a wireless station transmits an encrypted message that uses a key stored in a specific key index, the transmitted message indicates the key index that was used to encrypt the message body. The receiving access point or wireless station can then retrieve the key that is stored at the key index and use it to decode the encrypted message body.

Set up a Client with Open Authentication and No Data Encryption (None)

In device to device mode, also called ad hoc mode, wireless computers send information directly to other wireless computers. You can use ad hoc mode to network multiple computers in a home or small office, or to set up a temporary wireless network for a meeting.

On the Intel(R) PROSet/Wireless main window, use one of the following methods to connect to a device to device network:

• Double-click a Device to Device (ad hoc) network in the Wireless Networks list.
• Select a network in the Wireless Networks list. Click Connect. The Intel(R) PROSet/Wireless software automatically detects the security settings for the wireless adapter.
• Create a device to device (ad hoc) network profile as described next.

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

1. Click Profiles on the Intel(R) PROSet/Wireless main window.
2. On the Profiles list, click Add to open the wireless profile General Settings.
3. Profile Name: Enter a descriptive profile name.
4. Wireless Network Name (SSID): Enter the name of your wireless network.
5. Operating Mode: Click Device to Device (ad hoc).
6. Click Next to open the Security Settings.
7. Personal Security is selected by default.
8. Security Settings: The default setting is None, which indicates that there is no security on this wireless network.
9. Click OK. The profile is added to the Profiles list and connects to the wireless network.

Set up a Client with WEP 64-bit or WEP 128-bit Data Encryption

When WEP data encryption is enabled, a network key or password is used for encryption.

A network key is provided for you automatically (for example, it might be provided by your wireless network adapter manufacturer), or you can enter it yourself and specify the key length (64-bit or 128-bit), key format (ASCII characters or hexadecimal digits), and key index (the location where a specific key is stored). The greater the key length, the more secure the key.

To add a network key for a Device to Device (ad hoc) network connection:

1. On the Intel(R) PROSet/Wireless main window, double-click a Device to Device (ad hoc) network in the Wireless Networks list or select the network and click Connect.
2. Click Profiles to access the Profiles list.
3. Click Properties to open the wireless profile General Settings. The Profile name and Wireless Network Name (SSID) display. Device to Device (ad hoc) should be selected as the Operating Mode.
4. Click Next to open the Security Settings.
5. Personal Security is selected by default.
6. Security Settings: The default setting is None, which indicates that there is no security on this wireless network.

To add a password or network key:

1. Security Settings: Select either WEP 64-bit or WEP 128-bit to configure WEP data encryption with a 64-bit or 128-bit key.

When WEP encryption is enabled on an access point, the WEP key is used to verify access to the network. If the wireless device does not have the correct WEP key, even though authentication is successful, the device is unable to transmit data through the access point or decrypt data received from the access point.

Set up a Client with WPA*-Personal (TKIP) or WPA2*-Personal (TKIP) Security Settings

WPA Personal Mode requires manual configuration of a pre-shared key (PSK) on the access point and clients. This PSK authenticates a user's password or identifying code, on both the client station and the access point. An authentication server is not needed. WPA Personal Mode is targeted to home and small business environments.

WPA2 is the second generation of WPA security that provides enterprise and consumer wireless users with a high level of assurance that only authorized users can access their wireless networks. WPA2 provides a stronger encryption mechanism through Advanced Encryption Standard (AES), which is a requirement for some corporate and government users.

To configure a profile with WPA-Personal network authentication and TKIP data encryption:

1. On the Intel(R) PROSet/Wireless main window, double-click an infrastructure network in the Wireless Networks list or select the network and click Connect.
2. Click Profiles to access the Profiles list.
3. Click Properties to open the wireless profile General Settings. The Profile name and Wireless Network Name (SSID) display. Network (Infrastructure) should be selected as the Operating Mode.
4. Click Next to open the Security Settings.
5. Personal Security is selected by default.
6. Security Settings: Select WPA-Personal (TKIP) to provide security to a small business network or home environment. A password, called a pre-shared key (PSK), is used. The longer the password, the stronger the security of the wireless network.

If your wireless access point or router supports WPA2-Personal, then you should enable it on the access point and provide a long, strong password. The longer the password, the stronger the security of the wireless network. The same password entered in the access point needs to be used on this computer and all other wireless devices that access the wireless network.

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

7. Wireless Security Password (Encryption Key): Enter a text phrase with eight to 63 characters. Verify that the network key matches the password in the wireless access point.
8. Click OK to return to the Profiles list.

Set up a Client with WPA-Personal (AES-CCMP) or WPA2-Personal (AES-CCMP) Security Settings

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 enforces 802.1X authentication and key-exchange and only works with dynamic encryption keys. For a home user or small business, WPA-Personal usess either Advanced Encryption Standard - Counter CBC-MAC Protocol (AES-CCMP) or Temporal Key Integrity Protocol (TKIP).

NOTE: For the Intel(R) Wireless WiFi Link 4965AGN adapter, to achieve transfer rates greater than 54 Mbps on 802.11n connections, WPA2-AES security must be selected. No security (None) can be selected to enable network setup and troubleshooting.

To create a profile with WPA2-Personal network authentication and AES-CCMP data encryption:

1. On the Intel(R) PROSet/Wireless main window, double-click an infrastructure network from the Wireless Networks list or select the network and click Connect.
2. Click Properties to open the wireless profile General Settings. The Profile name and Wireless Network Name (SSID) display. Network (Infrastructure) should be selected as the Operating Mode.
3. Click Next to open the Security Settings.
4. Personal Security is selected by default.
5. Security Settings: Select WPA2-Personal (AES-CCMP) to provide this level of security in the small network or home environment. It uses a password also called a pre-shared key (PSK). The longer the password, the stronger the security of the wireless network.

AES-CCMP (Advanced Encryption Standard - Counter CBC-MAC Protocol) is the new method for privacy protection of wireless transmissions specified in the IEEE 802.11i standard. AES-CCMP provides a stronger encryption method than TKIP. Choose AES-CCMP as the data encryption method whenever strong data protection is important.

If your Wireless access point or router supports WPA2-Personal, then you should enable it on the access point and provide a long, strong password. The same password entered into the access point needs to be used on this computer and all other wireless devices that access the wireless network.

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

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

7. Password: Wireless Security Password (Encryption Key): Enter a text phrase (length is between eight and 63 characters). Verify that the network key used matches the wireless access point key.
8. Click OK to return to the Profiles list.

Enterprise Security Settings

Enterprise Security Settings Description

Configure Profiles for Infrastructure Networks

An infrastructure network consists of one or more access points and one or more computers with wireless adapters installed. Each access point must have a wired connection to a wireless network.

Set up a Client with Open or 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. Client access is granted only if the client 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. Once an invader finds the challenge string, the shared authentication key can be easily reverse engineered. Therefore, open authentication is actually, and counter intuitively, more secure. To create a profile with shared authentication:

1. Click Profiles on the Intel(R) PROSet/Wireless main window.
2. On the Profile Page, click Add to open the Create Wireless Profile General Settings.
3. Profile Name: Enter a descriptive profile name.
4. Wireless Network Name (SSID): Enter the network identifier.

Pass phrase (128-bit)	Enter 13 alphanumeric characters, 0-9, a-z or A-Z.
WEP key (128-bit)	Enter 26 hexadecimal characters, 0-9, A-F.

13. Key Index: Select 1,2, 3, or 4. Change the Key Index to specify up to four passwords.
14. Click OK.

Set up a Client 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 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:

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. 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 encryption with TTLS authentication.

To set up a client with TTLS Network Authentication:

1. Click Profiles on the Intel(R) PROSet/Wireless main window.
2. On the Profile page, click Add to open the Create Wireless Profile General Settings.
3. Profile Name: Enter a descriptive profile name.
4. Wireless Network Name (SSID): Enter the network identifier.
5. Operating Mode: Click Network (Infrastructure).
6. Click Next to open the Security Settings.
7. Select Enterprise Security.
8. Network Authentication: Select WPA-Enterprise or WPA2-Enterprise.
9. 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.
10. Enable 802.1X: Selected.
11. Authentication Type: Select TTLS to be used with this connection.

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(R) PROSet/Wireless 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.

Set up a Client 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 (for example, 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.

To set up a client with PEAP Authentication:

Obtain and install a client certificate. See Set up the Client for TLS authentication or consult your administrator.

1. Click Profiles on the Intel(R) PROSet/Wireless main window.
2. On the Profile page, click Add to open the Create Wireless Profile General Settings.
3. Profile Name: Enter a descriptive profile name.
4. Wireless Network Name (SSID): Enter the network identifier.
5. Operating Mode: Click Network (Infrastructure).
6. Click Next to open the Security Settings.
7. Select Enterprise Security.
8. Network Authentication: Select WPA-Enterprise or WPA2-Enterprise.
9. 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.
10. Enable 802.1X: Selected.
11. 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 (for example, 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: Select one of the following: 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(R) PROSet/Wireless 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%\%username%
• %username%@%domain%
• %username%@%domain%.com
• %username%@mynetwork.com

If Roaming Identity is cleared, %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. Below are instructions on how to configure a profile that uses PEAP authentication with

GTC, MS-CHAP-V2 (Default), or TLS authentication protocols.

Cisco Compatible Extensions Options

Cisco Options: Use to enable or disable Radio Management and Mixed Cells Mode or Allow Fast Roaming (CCKM).

NOTE: Cisco Compatible Extensions are automatically enabled for CKIP, LEAP or EAP-FAST profiles. To override this behavior, select or clear options on this page.

• Allow Fast Roaming (CCKM): Select to enable the client wireless adapter for fast-secure roaming. When a wireless LAN is configured for fast reconnection, an EAP-FAST, EAP-TLS, PEAP-GTC, PEAP-MS-CHAP-V2 or LEAP-enabled client device can roam from one access point to another without involving the main server. Use Cisco Centralized Key Management (CCKM), an access point configured to provide Wireless Domain Services (WDS), to take the place of the RADIUS server and authenticate the client without perceptible delay in voice or other time-sensitive applications.

Enable Cisco Compatible Options: Select to enable Cisco Compatible Extensions for this wireless connection profile.

• Enable Radio Management Support: Select to have your wireless adapter provide radio management to the Cisco infrastructure. If the Cisco Radio Management utility is used on the infrastructure, it configures radio parameters, detects interference and rogue access points. Default setting is selected.
• Enable Mixed Cells Mode: Select to allow the wireless adapter to communicate with mixed cells. A mixed cell is a wireless network in which there are both devices that use WEP and devices that do not. See Mixed Cells Mode for more information. The default setting is cleared.

Set up a Client with EAP-FAST Network Authentication

In Cisco Compatible Extensions, Version 3 (CCXv3), Cisco added support for EAP-FAST (Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling), which uses protected access credentials (PACs) to establish an authenticated tunnel between a client and a server.

Cisco Compatible Extensions, Version 4 (CCXv4) improves the provisioning methods for enhanced security and provides innovations for enhanced security, mobility, quality of service, and network management.

10. Data Encryption Select AES-CCMP.
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, Intel(R) PROSet/Wireless does not prompt the user for acceptance of the PAC. If the PAC is invalid, Intel(R) PROSet/Wireless 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.

To import a PAC:

1. Click Import to import a PAC from the PAC server.
2. Click Open.
3. Enter the PAC password (optiona).
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:
   • Use a user certificate on this computer: Click Select to choose the user certificate. Click OK. Proceed to Step 4.
   • Use the certificate issued to this computer: Proceed to Step 5.
   • Use my smart card: Select if the certificate resides on a smart card. Proceed to Step 5.
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 a 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.

1. Click OK.
2. Select the profile on the Wireless Networks list.
3. Click Connect. When prompted, enter the user name, domain and one-time password (OTP).
4. Click OK.

MS-CHAP-V2

This parameter specifies the authentication protocol operating over the PEAP tunnel.

1. Select the user credentials: Use Windows logon, Prompt each time I connect, or Use the following.
2. 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(R) PROSet/Wireless 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 was installed on a user's computer that did not apply the Cisco Compatible Extensions, Version 4 Application Setting, only EAP-FAST User settings are available for configuration.

To set up a client with EAP-FAST authentication:

1. Click Profiles on the Intel(R) PROSet/Wireless main window.
2. On the Profile page, click Add to open the Create Wireless Profile General Settings.

   • 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.
10. Enable 802.1X: Selected.
11. Authentication Type: Select EAP-FAST to be used with this connection.
12. Click Cisco Options to select Allow Fast Roaming (CCKM), which enables the client wireless adapter for fast secure roaming.

EAP-FAST User

Select the credential retrieval method:

1. Select the user credentials: Use Windows logon, Prompt each time I connect, or Use the following.
2. Allow automatic 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.

Click PACs to view any PACs that have already been provisioned and reside on this computer. A PAC must have already been obtained to clear Allow automatic provisioning on the Security Settings.

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

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.

To import a PAC:

1. Click PACs to open the Protected Access Credentials (PAC) list.
2. Click Import to import a PAC that resides on this computer or a server.
3. Select the PAC and click Open.
4. Enter the PAC password (optional).
5. Click OK to close this page. The selected PAC is added to PAC list.
