Security for mobile devices in a wireless network

1. A network, comprising:

a wireless access node configured to receive first packets from a plurality of wireless computing devices attempting to access the network, each of the first packets corresponding to one of a plurality of traffic types, at least one of the traffic types corresponding to an encrypted wireless protocol, the wireless access node being configured to associate one of a plurality of identifiers with each of the first packets, each of the plurality of identifiers corresponding to one of the plurality of traffic types and one of a plurality of virtual local area networks (VLANs), the wireless access node further being configured to transmit all first packets received from the wireless computing devices to a gateway on the network regardless of destination addresses associated with the first packets;

the gateway which is configured to determine that one or more of the first packets from a first one of the wireless computing devices are directed to a second one of the wireless computing devices with reference to the identifier associated with the one or more first packets and the identifier associated with the second wireless computing device, the gateway further being configured to prevent the one or more first packets from reaching the second wireless computing device in response to determining that the one or more first packets are directed to the second wireless computing device, thereby inhibiting all packet traffic between different ones of the VLANs on the network and between different devices on a same one of the VLANs on the network.

2. The network of claim 1 wherein at least some of the identifiers comprise service set identifiers (SSIDs) that correspond to the virtual local area networks (VLANs).

3. The network of claim 1 wherein the plurality of traffic types includes Wi-Fi Protected Access (WPA) traffic, WPA2 traffic, AES traffic, WEP traffic, and VoIP traffic.

4. The network of claim 1 wherein the plurality of traffic types includes first traffic corresponding to a specific corporate entity.

5. The network of claim 1 further comprising a wired access node which is configured to receive third packets from a plurality of wired computing devices attempting to access the network, each of the third packets corresponding to one of a second plurality of traffic types each of which corresponds to one of the plurality of identifiers, the wired access node being configured to associate one of the identifiers with each of the third packets, the wired access node further being configured to transmit all third packets received from the wired computing devices to the gateway regardless of destination addresses associated with the third packets.

6. The network of claim 5 wherein the gateway is further configured to determine that one or more of the third packets from one of the wired computing devices are directed to a specific one of the wired and wireless computing devices, the gateway further being configured to prevent the one or more third packets from reaching the specific one of the wired and wireless computing devices in response to determining that the one or more third packets are directed to the specific one of the wired and wireless computing devices.

7. The network of claim 1 further comprising a high-bandwidth connection to the Internet by which the gateway is configured to transmit at least some of the first packets to the Internet, the network further comprising one or more of a firewall, an intrusion detection system, or an intrusion prevention system, each of which is configured to protect the network from external packets from the Internet.

8. The network of claim 7 wherein one or more of the firewall, the intrusion detection system, or the intrusion prevention system is implemented on one of the gateway or an intervening network device on the network.

9. The network of claim 7 wherein at least one device on the network is configured to perform network address translation to facilitate transmission of the first packets to the Internet.

10. The network of claim 1 wherein the gateway is further configured to perform network address translation to facilitate transmission of at least some of the first packets on the network.

11. The network of claim 1 wherein the gateway is further configured to supply locally valid network address to at least some of the wireless computing devices to facilitate transmission of at least some of the first packets on the network.

12. The network of claim 1 wherein the gateway is further configured to process specific packets associated with a first one of the identifiers in accordance with a set of security options.

13. The network of claim 12 wherein the set of security options is determined with reference to input from a user associated with a specific computing device from which at least some of the specific ones of the specific packets originated.

14. The network of claim 13 wherein input from the user is obtained dynamically after the specific computing device connects to the network.

15. The network of claim 13 wherein input from the user is obtained prior to the specific computing device connecting to the network.

16. The network of claim 12 wherein the set of security options is determined with reference to one or both of a type of the specific computing device from which the specific first packets originated or a type of a specific access node by which the specific computing device connected to the network.

17. The network of claim 1 wherein the gateway is further configured to establish a secure connection between at least one of the wireless computing devices and at least one other computing device on the network.

18. The network of claim 17 wherein the gateway is further configured to process packets associated with the secure connection in accordance with a set of security options.

19. The network of claim 18 wherein the gateway is further configured to apply a different subset of the security options to packets originating from each of the computing devices associated with the secure connection.

20. The network of claim 1 wherein the wireless access node is deployed on a property local area network (LAN), the network further comprising a plurality of such property LANs, and a plurality of regional points-of-presence (POPs), each of the regional POPs forming a wide area network (WAN) with a subset of the property LANs and being configured to facilitate secure Internet access via a high-bandwidth connection for the wireless computing devices connected to the associated subset of property LANs, the gateway being deployed either on the property LAN with the wireless access node or on the associated POP, the network further comprising a central services network forming a WAN with all of the regional POPs, the central services network being configured to centrally monitor and manage operation of the regional POPs and the property LANs.
