A security update status of a device is evaluated; and one or more of a plurality of security policies are selected to apply to the device based on the security update status. The available security philosophies may include, for example, a “protect the good” philosophy, an “encourage the busy” philosophy and a “shut off the non-compliant” philosophy. The security update status can evaluate, for example, a version level of one or more security features installed on the device or can be based on a flag indicating whether the device satisfies predefined criteria for maintaining one or more computer security protection features up-to-date.

Abstract: A technique for lessening the likelihood of congestion in a congestible node is disclosed. In accordance with the illustrative embodiments of the present invention, one node—a proxy node—drops protocol data units to lessen the likelihood of congestion in the congestible node. In some embodiments of the present invention, the proxy node receives a metric of a queue at a congestible node and, based on the metric, decides whether to drop protocol data units en route to the congestible node. In some other embodiments of the present invention, the proxy node estimates a metric of a queue at a congestible node and, based on the metric, decides whether to drop protocol data units en route to the congestible node.

Abstract: A method and apparatus are disclosed that enable a data-processing system, such as a server, to determine whether or not to grant a telecommunications terminal one or more privileges, without some of the disadvantages of the prior art. Specifically, in accordance with the illustrative embodiments of the present invention, a call-processing server transmits, to a first terminal, a first signal for verifying a second terminal, such as one that has been designated by a user. The user is then required to transmit a second signal to the call-processing server via the second terminal. The call-processing server then examines the received second signal with respect to the first signal and determines whether or not to grant the second terminal a privilege (e.g., handling calls on behalf of the user, etc.), based on the relationship between the first and second signals.

Abstract: A technique is disclosed for detecting hidden wireless routers that constitute security threats in telecommunications networks that comprise a wireless network portion and a wireline network portion. In accordance with the illustrative embodiment of the invention, a test station is used in the wireless portion of a network to detect the presence of a hidden wireless router. Furthermore, in some embodiments, a test server is used in the wireline portion of the network in order to detect packets that are illegitimately routed from the wireless portion to the wireline portion of the network through the hidden wireless router.

Abstract: A method for providing priority access to 802.11 endpoints. The method includes the steps of sending a Clear To Send (CTS) frame from a designated station, without requiring a Request to Send (RTS) frame from a first station. The CTS frame includes a field identifying the first station for commencing transmission, and a field indicating a duration of transmission. A deferring step is also performed for deferring any transmissions of stations other than the first station until after the duration indicated in the CTS frame has passed.

Abstract: A method and apparatus are provided for authenticating the contents of a device requesting access to a first network, such as an enterprise network. If a device has connected to at least one other network then the content of the device is evaluated prior to obtaining access. The scope of the content evaluation may be based, for example, on properties of the other network or on one or more defined content authentication rules. If a device attempts to access a network, the content of the device is evaluated and the device may be restricted to accessing only one or more restoration services if the content fails to satisfy one or more predefined criteria, such as a content item that is out of date or a determination that the device connected to one or more external networks. The restoration service(s) can update a content item that is out of date, reinstall one or more programs or return configuration settings to default values.

Abstract: A method and apparatus are disclosed that enable a call-processing server to extend a received call out to a telecommunications terminal endpoint, wherein the terminal, such as a hotel room phone, is local to and accessible only through an intermediate point, such as a hotel switchboard. Also disclosed are a method and apparatus that enable a data-processing system, such as a server, to determine whether or not to grant a telecommunications terminal endpoint one or more privileges, without some of the disadvantages of the prior art. The methods and apparatus that are taught in this disclosure can be used for extending the incoming call to the endpoint independently of or in the absence of determining whether or not to grant privileges to the endpoint.

Abstract: A wireless local area network (LAN), and a method of operating the same, prevents unauthorized users from accessing the wireless LAN. A signal strength of a station attempting to access the wireless LAN is measured. If the signal strength is less than a predetermined threshold value, the system concludes that the station is outside of an authorized geographical area. Such a station attempting to establish a connection is characterized as an unauthorized station, and access to the wireless LAN is denied. The system may also periodically verify that authorized stations remain within the authorized geographical area. A station that has moved outside of the authorized geographical area can be notified or denied further access to the wireless LAN.

Abstract: A method and apparatus are disclosed for assessing the available resources in a network and using the assessment for admission control. A VoIP call can be established with a device only if the network has sufficient resources to accommodate the call or it is possible to make such resources available by curtailing ongoing data connections. A network utilization characteristic (NUC) provides a measure of network capacity. The network utilization characteristic of a flow is the fraction of time the network is busy transmitting data for that flow. The sum of the network utilization characteristics of all flows yields the fraction of time the network is busy transmitting data. The difference between one and the sum of all flows indicates the time that the network is idle in the measured time interval. A new flow can be accommodated if the NUC of the new flow is smaller than this difference value.
