NETWORK-ASSISTED HEALTH REPORTING ACTIVATION
First Claim
1. A computer-readable medium whose contents are capable of causing a computing system to perform a method for discerning network host health in a network, the method comprising:
- monitoring traffic on the network to observe (a) statements of health sent by hosts connected to the network and (b) traffic of at least one other type sent by hosts connected to the network;
maintaining a list of hosts connected to the network from which a statement of health has been observed; and
when traffic of the other type is observed from a host connected to the network that is not included in the maintained list, taking an action intended to cause the host to send a statement of health.

Abstract
A system and method for generating and tracking health diagnoses of devices connected to a computer network via a statement of health provided by each device. The system monitors the health of devices on the network and attempts to engage the operator of undiagnosed devices in order to provide a diagnosis. Undiagnosed devices are quarantined to restrict their access to network resources. For example, access requests from quarantined devices to certain Web services may be intercepted and the device redirected to a page informing the operator of the need to provide a health diagnosis by installing or activating a compatible system health agent.

9. A method for discerning network host health in a network, comprising:
-
in a device connected to the network, monitoring traffic on the network to observe (a) statements of health sent by hosts connected to the network and (b) traffic of at least one other type sent by hosts connected to the network; when traffic of the other type is observed from a host connected to the network from which no statement of health has been observed, providing communication to a user of the host offering a first alternative of installing and/or activating a system health agent on the host, and a second alternative of having network access control restrictions imposed on the host; if the user of the host elects the first alternative, assisting the user of the host in installing and/or activating a system health agent on the host; and if the user of the host elects the second alternative, causing network access control restrictions to be imposed on the host. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system for tracking the state of health of devices connected to a network, the system comprising:
-
a component that receives a statement of health from at least one device connected to the network; a component that generates a diagnosis for the at least one device connected to the network based on the received statement of health; a component that maintains a list of devices connected to the network for which a health diagnosis has been generated; and a component that, in response to receiving data from an undiagnosed device, causes the operator of the device to be prompted to take action to enable the reporting of a statement of health. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A method performed by a computer having a memory and a processor, the method comprising:
-
monitoring traffic on a network to observe (a) statements of health sent by devices connected to the network and (b) traffic of at least one other type sent by devices connected to the network; and when traffic is observed from a device connected to the network from which a statement of health indicating that the device is healthy has not been received, sending a notification that the device is accessing the network without providing a statement of health indicating that the device is healthy. - View Dependent Claims (25, 26)
