Described is a technology for managing network security by having network clients that are capable of self-assessment assess themselves for security risks and/or security vulnerabilities. Other clients may be remotely assessed for security risks and/or security vulnerabilities. Assessments may include antimalware scans, vulnerability assessment, and/or port scans. The results of the self-assessments and remote assessments are combined into a data set (e.g., a view) indicative of the network security state. In this manner, for example, significant network resources are conserved by allowing those clients capable of self-assessment to assess themselves and thereafter only provide their self-assessment results. Clients capable of self-assessment may also be remotely assessed, to determine whether any discrepancies exist between their remote assessments and self-assessments. Clients may be discovered, along with their self-assessment capabilities, by network communication.

Combining assessment models and client targeting to identify network security vulnerabilities

Implementations of client health validation using historical data are described. In one implementation, historical data on a client, such as a laptop, attempting to access a network is scanned. The historical data can come in many forms, including cookies and application data caches saved on the client. The historical data can be used to assess a health of the client. For example, if historical data stored in an application data cache indicates interactions between the client and a website known to disseminate malicious agents, the client can be assessed to have unacceptable health. Alternately, if the historical data indicates that the client has not interacted with enough suspicious sources to constitute a danger to the network, the client can be assessed to have acceptable health. In such a case, the client can be allowed to access the network.
