Abstract: Conditional policies can be defined that change based on security measurements of network endpoints. In an example embodiment, a network traffic monitoring system can monitor network flows between the endpoints and quantify how secure those endpoints are based on analysis of the network flows and other data. A conditional policy may be created that establishes one or more first connectivity policies for handling a packet when a security measurement of an endpoint is a first value or first range values, and one or more second connectivity policies for handling the packet. The connectivity policies may include permitting connectivity, denying connectivity, redirecting the packet using a specific route, or other network action. When the network traffic monitoring system detects a change to the security measurement of the endpoint, one or more applicable policies can be determined and the system can update policy data for the network to enforce the policies.

Abstract: An example method can include receiving a traffic report from a sensor and using the traffic report to detect intra-datacenter flows. These intra-datacenter flows can then be compared with a description of historical flows. The description of historical flows can identify characteristics of normal and malicious flows. Based on the comparison, the flows can be classified and tagged as normal, malicious, or anomalous. If the flows are tagged as malicious or anomalous, corrective action can be taken with respect to the flows. A description of the flows can then be added to the description of historical flows.
