The following questions and answers provide some background information about the Cisco® Secure Services Client and its origins. In addition, under "Product Details," you will find in-depth information about the functions of the client and its interoperability with Cisco solutions.

Q. What is the Cisco Secure Services Client?
A. The Cisco Secure Services Client is client software that resides on the device to manage the user identity and create secure network connections. It is an endpoint security and management solution for deploying and managing identity-based network access control for enterprise networks. It provides IT managers with a Layer 2 security framework that uses an industry-standard 802.1X implementation for protecting endpoint devices. Cisco Secure Services Client works across platforms to provide a common authentication framework across wired and wireless networks. Table 1 lists some of the main features of Cisco Secure Services Client.

Q. Why is the product called Cisco Secure Services Client?
A. The name Cisco Secure Services Client reflects two important aspects of the product: first, that it supports the industry-leading 802.1X standard for secure, extensible device authentication across wired and wireless networks; and second, that it delivers a range of services to the client based on the identity of the user and device. These services include:

Authentication services: 802.1X

Encryption services for data and management: Wi-Fi Protected Access (WPA) and WPA2

Cisco Compatible Extensions devices and services: Diagnostic services, voice services, and location services (for Windows Vista when used with a wireless network interface card that supports Cisco Compatible Extensions Version 5, which integrates the Vista Cisco Compatible Extensions SDK)

Q. What are the benefits of the Cisco Secure Services Client?
A. The Cisco Secure Services Client enables IT departments to design and implement an 802.1X-based security strategy that positions the endpoint device as a defensible and secure new perimeter for wired and wireless networks. As a result, IT managers can deploy identity-based network security that can simultaneously enforce machine and user authorization rights, protect the integrity of devices, and reduce security breaches to the corporate network. Furthermore, the solutions are designed to simplify and enforce wired Ethernet and Wi-Fi access control policies, regardless of device, network, or authentication technology. Table 2 lists the main features and benefits of Cisco Secure Services Client.

Q. Is the Cisco Secure Services Client supported by the Cisco Secure ACS?
A. Yes. The Cisco Secure Services Client is fully supported by the Cisco Secure ACS platform. The combination of the client supplicant and back-end authentication server provides customers with a comprehensive solution for robust client authentication across wired and wireless networks.
Q. How does the Cisco Secure Services Client work with the Cisco Unified Wireless Network?
A. The Cisco Secure Services Client allows enterprises to securely authenticate a variety of client devices to the wired and wireless network. The supplicant is fully supported by the Cisco Unified Wireless Network and works with the existing Cisco portfolio of access points and wireless LAN controllers.
Q. Will the Cisco Secure Services Client become a part of the Trusted Computing Group (TCG) and Trusted Network Connect (TNC) working groups?
A. Cisco currently has no plans to join the TCG or TNC working groups. Cisco believes that the protocols required for endpoint integrity should be developed under the IETF, where other Internet protocols are standardized. Cisco is working with the members of TNC at the IETF to further advance the interest in standardizing the protocols for endpoint integrity.
Q. What is the part number of the Cisco Secure Services Client Version 5.1, and how can I order it?
A. The Cisco Secure Services Client is available on the Cisco Global Price List and can be ordered as a standard Cisco product. Use the following part numbers to place an order: AIR SC5.0-XP2K for Windows 2000 and XP and AIR-SC5.0-VISTA for Windows Vista.

Product Details

Q. How does Cisco Secure Services Client 5.1 interface facilitate the end user experience?
A. The interface provides a convenient "two-click connect" to office, home, and public wired and wireless networks. This allows end users to connect to the network more easily and eliminates the security concerns of connecting to an open (public) wireless network. The user interface also provides a comprehensive range of features and is accessible by right-clicking the taskbar icon or using the desktop icon. End users can view the connection status indicator for network name, strength, connection status, and IP address. Finally, the integration of the VPN client combined with its automated activation represents a significant simplification for the end user.
Q. What is the Enterprise Deployment feature?
A. With the new Enterprise Deployment feature that is available in Cisco Secure Services Client 5.1, IT administrators can configure and deploy user profiles through a single XML file or the Cisco supplied management utility, a wizard that steps the IT administrator through the policy and configuration settings for users, devices, and networks. This reduces the time and cost required to deploy and set up the client on end-user systems.

Q. Does the Cisco Secure Services Client allow the wireless adapter radio to be turned off and on?
A. Yes. However, not all wireless cards support the mechanism used to control power on the card, so it will not work with all devices. It should be noted that turning the adapter radio off puts the adapter in standby mode, and standby mode is not the same as disabling or uninstalling the adapter.
Q. Can both device and user group policy object (GPO) functions be used with the Cisco Secure Services Client?
A. In Windows Vista, SSC does not work in conjunction with wired and wireless GPOs. All other types of GPOs are supported on both x32 and x64 Windows Vista platforms.
Q. Can different authentication methods be used for device and user authentication?
A. Separate authentication methods can be used for machine and user authentication. This function is under the control of the RADIUS server. For this reason, at present you need to use a RADIUS server, such as Cisco Secure ACS, that can filter on the host and identity prefixes sent during device authentication. Because the server will then know that the authentication is for a device, it can be configured to use the desired method.
Q. Is the Cisco Secure Services Client interoperable with Cisco LAN switches?
A. The Cisco Secure Services Client is interoperable with any Cisco LAN switch that supports the IEEE 802.1X protocol for authentication.
Q. Does the Cisco Secure Services Client allow network administrators to define a "work" network for end users that is locked, but that still allows them to create their own network access profiles?
A. Yes, by using the deployment wizard to create a set of deployment files. By selecting Configurable Client as the Client Type on the Station Policy, end users can define their own networks. Administrators can control the types of networks that the end user defines using the Network Policy, Wi-Fi Policy, and Authentication Policy categories. During the deployment, administrators define the "work" network and copy these files to the end users' workstations. As part of the client deployment, the access profile entitled "work" is automatically locked, and end users cannot modify them. Additionally, end users can create new networks within the policy boundaries set by the administrator.
