5.0 DEFINITIONS: The following definitions are applied throughout this policy:

    5.1 Wireless Local Area Network (WLAN) is a local area network (LAN) that users access through a wireless connection.   802.11 standards specify WLAN technologies. WLANs may connect directly to various enterprise networks in the State of Kansas, including the KANWIN neetwork, or may connect indirectly via the Internet and Virtual Private Networks (VPN). The State of Kansas defines WLANs in the following categories:

      5.1.1 Business Class Network: Business Class Networks are WLANs that are owned and operated by the State of Kansas and are used by State empolyees and other authorized persons to access internal information technology resources.

      5.1.2 Guest Network: a WLAN owned and operated by the State of Kansas to provide access to the Internet and State websites, and applications that are publicly accessible via the Internet. The use of Guest Networks is limited to those persons visiting State-owned facilities that have a business need to communicate over the Internet. Guest Networks are not intedned to be used as Public hotspots and do not provide free, open access. All Guest Networks installed by State agencies shall be logically separated and fire-walled from Business Class Networks and internal State Networks.

      5.1.3 Public Hot Spot: a wireless LAN node that provides Internet connection and virtual private network (VPN) access from a given location. Public places, such as airports, hotels and coffee shops, may provide wireless access for customers. Public Hotspots may or may not protect WLAN network traffic through the use of encryption. When using a hotspot, the user shall always assume that the network is open and not secure in any way.

      5.1.4 Home Network: A home network is privately owned by the State employee. Home networks typically deploy inexpensive, off-the-shelf, wireless access points, routers, and network interface cards, that may or may not conform to State security requirements for encryption, authentication protocols, VPN support, or other security mechanisms.

    5.2 KITA: Kansas Information Technology Architecture, also referred to as the State of Kansas Technical Architecture, describes the information systems infrastructure that supports applications used by the State.

    5.3 Security Mechanisms: Software or hardware devices used to secure a network or computer system. Examples of security mechanisms include passwords, firewalls, antivirus software, virtual private networks and encryption protocols.

    5.4 Personal Firewall: also referred to as a desktop firewall, is a software application used to protect a single internet-connected computer from intruders. Personal firewalls protect the integrity of desktop or laptop computers' operating systems and files systems from malicious computer code, by screening traffic in the same way that network based screening firewalls protect an enterprise network, filtering inbound and outbound traffic.

    5.5 User Registration: User registration is the act of identifying a user to the network, with subsequent measures of authenticating and authorizing the user. Registration requirements may vary based on the security level of the network accessed, as well as the business reasons for accessing the network.

    5.6 Private Network: a network not owned by the State, that is accessed by users of State WLAN networks. For example, a vendor accessing their own corporate network from the State's WLAN network.

    5.7 Virtual Private Network (VPN): is a network that uses a public telecommunication infrastructure. A VPN uses tunneling and encryption protocols to maintain privacy across the public network.

    5.8 Mobile Computing Device: a laptop computer, handheld computer, cellphone, blackberry wireless communicator, or other portable computing device used for data communications and/or data storage.

    5.9 Academic Network: Academic wireless networks are designed to maintain academic traditions of free and open access to information which is not sensitive and which is intended to be available to the public (Internet resources) or to the local campus community.

    5.10 DISC: The Division of Information Systems and Communications.

6.0 POLICY: In order to establish a common, uniform policy for all state agencies regarding the acquisition, installation, management, and use of wireless local area networks, the following WLAN policies are established. This policy supersedes any and all State agency WLAN policy(s). This policy shall be the governing document for all State agency WLAN policy.
