Abstract
In an example, a threat intelligence controller is configured to operate on a data exchange layer (DXL). The threat intelligence controller acts as a DXL consumer of reputation data for a network object, which may be reported in various different types and from various different sources. Of the devices authorized to act as reputation data producers, each may have its own trust level. As the threat intelligence controller aggregates data from various providers, it may weight the reputation reports according to trust level. The threat intelligence engine thus builds a composite reputation for the object. When it receives a DXL message requesting a reputation for the object, it publishes the composite reputation on the DXL bus.
