Techniques for securing a client. When a client, such as a portable computer, undergoes a change in operational state, an operating system agent sends a state message to a server. The state message describes the change in the operational state of the client. The operating system agent is one or more software modules that execute in an operating system of the client. The client receives a policy message from the server. The policy message contains policy data, which a BIOS agent stores in the BIOS of the client. The policy data identifies one or more security policies which the client should follow.

Portions of the operating system agent may monitor resources of the client. The operating system agent sends a message, which describes an operational state of the operating system agent, to a BIOS agent. The BIOS agent is one or more software modules operating in a BIOS of the client. The BIOS agent performs an action based on a policy that is described by policy data stored within the BIOS of the client. The BIOS agent performs the action in response to either (a) the operational state described by the message, or (b) the BIOS agent not receiving the message after an expected period of time.

Techniques for securing a client. A BIOS agent stores policy data within a BIOS of the client. The BIOS agent is one or more software modules that execute in the BIOS of the client. The policy data describes one or more policies which the client should follow. When an operating system agent detects that a condition, specified by a particular policy of the one or more policies, has been met, the operating system agent performs one or more actions specified by the particular policy, such as disabling the client, retrieving a file from the client, erasing a file from the client, or encrypting a file on the client. The operating system agent is one or more software modules that execute in the operating system of the client.

An electronic device, for example, a laptop computer includes a processor, a transceiver module, for example, a Bluetooth module and a memory. The memory includes a platform proximity agent, which may be implemented as a series of instructions, which when executed by the processor, causes the processor to receive a Bluetooth signal from a corresponding provisioned Bluetooth device, for example, a cellular telephone. Next, determine whether the received signal exceeds both a strength threshold level and a predetermined time threshold level, where the signal strength and time threshold levels are established when the laptop and a corresponding cell phone are paired during a provisioning process. When the received signal strength and duration both exceed the corresponding policy based thresholds, the laptop enters (or remains in) a full power state with full access to the monitor and the platform. On the other hand, when the received signal strength and duration both fall below (or are less than) the corresponding policy based threshold, the laptop enters (or remains in) a reduced power, or locked state.

Approaches for handling network resources in a virtualized computing environment. A first request for network resources is received from a first virtual machine. Policy data is consulted to determine how to service the first request. The first request is processed by providing the first virtual machine with access to only a first portion of network resources. A second request for network resources is received from a second virtual machine. Policy data is consulted to determine how to service the second request. The second request is processed by providing the second virtual machine with access to only a second portion of network resources that is not coextensive with the first portion. In this way, virtual machines may have access to particular resources and/or specific bounded areas of a network.

Approaches for synchronizing history data across a virtualized web browser. When a user instructs a virtualized web browser, executing on a host operating system, to display a web page, a host module executing on the host operating system may instruct a guest module executing within a particular virtual machine to retrieve the web page. The host module may provide to the guest module history data for the virtualized web browser. History data describes browsing history for the virtualized web browser, either in the current instance or for previous instances. The guest module performs operations in accordance with the history data. When the host module receives the screen data content from the guest module, the host module instructs the virtualized web browser to display the web page using the screen data content.
