Systems and methods intended to control a network devices access to a network are disclosed. Embodiments of the current invention expose a method for confining a network client's network access to a specific logical region of the network. A network communication may be received and the client that originated this communication determined. This client is associated with a set of rules or walled garden that specifies the access allowed by that client. The destination of the communication may also be determined and if the destination is allowed by the set of rules associated with the client and access to the destination allowed if access to the destination is allowed by the set of rules. Images(3) Claims(3)
1. A method for controlling access to network resources, comprising: receiving a network communication; determining a client associated with the network communication, wherein the client is associated with a set of rules; determining a destination from the network traffic; determining if the destination is allowed by the set of rules associated with the client; and allowing access to the destination if access to the destination is allowed by the set of rules. 2. The method of claim 1, further comprising redirecting the network communication if the destination is not within the set of rules. 3. The method of claim 2, wherein the network communication is redirected to a region of a network designed for constrained clients.
RELATED APPLICATIONS [0001] This application claims priority under 35 U.S.C. 119(e) to U.S. Provisional Patent Application No. 60/551,702, filed Mar. 10, 2004, entitled “System and Method for access Scope Control (“Walled Gardens”) for Clients of a Network Access Gateway,” to Patrick Turley, Keith Johnston, and Steven D. Tonnesen. TECHNICAL FIELD OF THE INVENTION [0002] Embodiments of the present invention relate generally to network access control and network protocol control. BACKGROUND [0003] The communication of data over networks has become an important, if not essential, way for many organizations and individuals to communicate. The Internet is a global network connecting millions of computers in which any computer connected to the Internet can potentially receive data from and send data to any other computer connected to the Internet. The Internet provides a variety of methods with which to communicate data, one of the most ubiquitous of which is the World Wide Web. Other methods for communicating data over the Internet include e-mail, usenet newsgroups, telnet, FTP, audio streams, and video streams. [0004] Users typically access the Internet either through a computer connected to an Internet Service Provider (“ISP”) or computer connected to a local area network (“LAN”) provided by an organization, which is in turn, connected to the ISP. The network service provider provides a point of presence to interface with the Internet backbone. Routers and switches in the backbone direct data traffic between the various ISPs. [0005] As the number of networked devices has increased so, too, has the amount and nature of network traffic. One unfortunate side effect is the evolution of destructive or unauthorized access to the data or operations of networked devices. While the option of simply removing all network access from an abusive or abnormal client remains, business etiquette often predicates the need to constrain a client's access, rather than to remove it. Additionally, when a client device is inadvertently tainted or “infected” by a software virus or worm, the user of the client device may be unaware that the device is abnormally affecting the network. As a result, various methods to detect and limit abnormal or abusive use of network resources or connected devices have resulted in a need to establish a controlled environment in a network in order that abusive or abnormal clients can be constrained. SUMMARY OF THE INVENTION [0006] Embodiments of the current invention present methods for confining a network client's network access to a specific region of the network. [0007] Embodiments of the present invention allow a service provider to use the network access gateway to constrain a network client's level of network access in a way that can inform the user of the problem and still allow the user access to a limited set of network destinations that may be helpful in resolving the problem (e.g. apply anti-virus software vendors, operating system or security patches, etc.). [0008] Embodiments of the present invention can also be used for other purposes relevant to a network access gateway such as allowing free access to chosen network content, but requiring additional payment or authorization for unrestricted access. An example of this is a public wireless network at a venue that wishes to provide free information about the venue via its own website or affiliated websites, yet requires payment for clients desiring general access to the Internet from the venue. [0009] Embodiments of the present invention may make use of network firewall rule technology, configured to recognize clients by identity or membership in a group. Once classified, traffic from a client can then be subjected to a particular list of access rules, or “walled garden”, by which network access is allowed. [0010] A network access gateway can support any number of these walled gardens and can dynamically move clients in and out of these walled gardens based on any status information it maintains, discovers, or is notified about from an external source. [0011] Embodiments of the present invention may offer the technical advantages of a way to reduce the negative effects of virus and worm infections at remote venues, thus helping to preserve the service levels expected by users and to maintain control of a network. Users can also be notified of computer infections and offered a means to seek resolution without requiring direct support from the service provider. Additionally the present invention may offer a dynamic means of selectively allowing clients limited access to content based on identity or membership in a group.

[0016] Attention is now directed to systems and methods for creating a rules based access system suitable for implementation in a network access gateway. Theses systems and methods may make use of an existing operating system network packet or firewalling subsystem and combines a traffic identification strategy with the application of destination-based access rules to create a controlled environment or “walled garden” capability for a network access gateway. Controlled environments, which limit the network segments or routes available, as well as the network protocol traffic permitted, are known as “walled gardens”, where a network client may be constrained in terms of the types of network protocols (and applications) that they are permitted network access, as well as the destinations or services to which network applications may connect. [0017] These systems and methods may also allow any client known to a system to be arbitrarily classified or grouped based on facts known to the system such as assigned client subnet, organizational boundaries, or security standing based on traffic patterns or content. External assignment may also possible. [0018] Embodiments of the current invention disclose methods and systems for confining a network client's network access to a specific logical region of the network. Embodiments of the present invention may make use of traffic discrimination techniques and network protocol filtering to recognize clients by identity or membership in a group. Once classified, traffic from a client can then be subjected to a particular list of access rules that specify a “walled garden” which define where network access is allowed. Network access confinement can be through limiting network protocol use, limiting network destination address resolution or limiting domain name resolution, leading to network address resolution. In certain embodiments, a controlling entity such as an automated security monitor may utilize the invention to limit a user's present level of network access in a way that can inform a user of certain conditions and still allow a user access to a set of network destinations that may be helpful (for example in resolving the condition that led to reduced access). [0019] Other embodiments of the present invention can also be used for other purposes relevant to a network access gateway such as allowing free access to chosen network content, but requiring additional payment or authorization for unrestricted access. An example of this is a public wireless network at a venue that wishes to provide free information about the venue via its own website or affiliated websites, yet requires payment for clients desiring general access to the Internet from the venue. [0020] FIG. 1 is a diagrammatic representation of a sample network topology illustrating an environment employing an embodiment of the present invention. It should be noted that FIG. 1 is provided by way of example only. In other embodiments of the present invention, the networks attached to the gateway 11 can be any networks known in the art including, but not limited to, LANs, WANs, the Internet, global communications networks, wireless networks and/or any other communications network known in the art. [0021] Clients 1, 2, 3, 4 on LAN network 10 are connected to Internet 13 via gateway 11. All network traffic from clients 1, 2, 3, 4 bound for Internet 13 is handled by gateway 11. Client computers 1, 2, 3, 4 can comprise any computing device known in the art (e.g., desktop, laptop, PDA, mobile phone or any other device capable of network communication) and can be connected to gateway 11 in any manner known in the art (e.g., by LAN, wireless network, direct connection or other manner known in the art). [0022] Gateway 11 may be operable to support any number of walled gardens 20, 30, 40 and any number of client classifications. Gateway 11 can assign clients 1, 2, 3, 4 to walled gardens 20, 30, 40 automatically based on facts known or learned at gateway 11, or the assignment can be done in response to external configuration or commands received at gateway 11. [0023] At network access gateway 11, incoming network traffic is inspected for attributes that identify the traffic as associated with a particular client 1, 2, 3, 4. In one embodiment using the Linux operating system, this is done using the netfilter network packet subsystem by the application of iptables match rules that test for attributes such as IP address, MAC address, or the network interface on gateway 11 where the traffic arrived. [0024] In one embodiment of the present invention, once incoming traffic is discriminated (and/or marked) on a per-client basis, traffic can be directed to, assigned to, or associated with, one or more sets of client-specific (or group-specific) access rules. Each access rule set serves to specify “walled garden” 20, 30, 40; definitions that consists of specifically allowed locations in an outside network. These lists can be manually constructed to contain selected websites (or other resources) that are relevant to the identified client or group. Each list's content may vary over time in response to external configuration or commands received. [0025] Clients 1, 2, 3, 4 who are assigned to a walled garden 20, 30, 40 and whose traffic is not addressed to a location in an access list corresponding to the assigned walled garden 20, 30, 40 may have the traffic dropped, denied, or redirected by gateway 11. In one embodiment, when this errant traffic is a web browser request, gateway 11 can redirect the request thus causing display of an informational page in the requesting user's web browser. The page to which the request is redirected may be generated by gateway 11 itself, or it may instead be served from a remote location. The page can inform the user of his status in the access gateway and offer choices of action. [0026] Turning now to FIG. 2 a representation of an example listing of gateway configuration details that specify per-client behavior is listing. Configuration 200 may be kept by gateway 11 and specify which walled garden 20, 30, 40 a client 1, 2, 3, 4 is associated with. Each client 1, 2, 3, 4 may be assigned a designated level of access. For example, the access granted to Client 2 includes only the destination addresses defined by the contents of the list indicated by “Walled Garden A” 20. The example configuration 200 may further specify what action, if any, should be taken if a client 1, 2, 3, 4 attempts to access a destination that is not specifically allowed. In the case of client 2, such a request would be redirected by gateway 11 to the address of site “Q”. In this example, site “Q” is implemented by web server 12 internal to gateway 11. [0027] The following set of results may occur if the listed actions were taken by clients as depicted with respect to FIGS. 1 and 2. These cases illustrate the ability of this embodiment to “quarantine” certain clients 1, 2, 3, 4 to particular walled garden(s) 20, 30 , 40 while simultaneously allowing other clients 1, 2, 3, 4 unhindered access to the internet 13. Attempting to Client Identity visit: Result Client 1 Site “J” Allowed Client 1 Site “K” Allowed Client 1 Site “M” Allowed Client 1 Site “P” Allowed Client 1 Site “S” Allowed Client 2 Site “J” Redirected Client 2 Site “K” allowed Client 2 Site “M” allowed Client 2 Site “P” redirected Client 2 Site “S” redirected Client 3 Site “J” Redirected Client 3 Site “K” allowed Client 3 Site “M” allowed Client 3 Site “P” allowed Client 3 Site “S” redirected Client 4 Site “J” Dropped Client 4 Site “K” dropped Client 4 Site “M” dropped Client 4 Site “P” dropped Client 4 Site “S” allowed [0028] Utilizing an embodiment of the present invention the following scenario may occur: Client 1 is accessing the internet 13 without restrictions from gateway 11. The client 1 computer becomes infected with a worm. The worm creates excessive network traffic. The gateway 11 notices the abusive traffic and “quarantines” client 1. In one embodiment the gateway may detect this infection based on observed, detected behavior fitting a pattern that is suitable for constraint. By assigning the client to a walled garden reserved for infected users traffic from this client to destinations outside the walled garden becomes restricted. [0029] The quarantined client may then attempt to browse a web page on the Internet. In response to this attempt, the gateway redirects the web request to a cooperating web server such as an internal web server on the gateway. The gateway's web server renders a web page informing the client of its perceived infection and offering links to self-help documents and to the websites of anti-virus vendors and the client's OS vendor. Thus, traffic from the client to the destination in the walled garden for infected users is allowed while other traffic is denied or redirected. [0030] To control access of a client only to sites with a particular set of rules corresponding to a “walled garden”, in some embodiments, network firewall technologies are employed to limit network protocol usage by a constrained client, while in other embodiments, network traffic filtering technologies are employed to limit network packet flow by the constrained client. In still other embodiments, network routing technologies are employed to limit network packet traversal by a constrained client. [0031] Constraining a client may also involve analysis of a network protocol. In one embodiment, all network requests from a client in network protocols other than HTTP are denied if they emanate from a constrained client. In this embodiment, a constrained client may only access certain network regions accessible utilizing HTTP, and these network regions may contain content intended to rectify aberrant behavior by the constrained client. More specifically, these network regions may contain content or data intended to repair or enhance a network client's network access and permit renewed access to the other portions of a network by the client, perhaps through the application of security patches.
