Abstract
There is disclosed in one example, a computing apparatus, including: a hardware platform including a processor and a memory; a network interface; a data exchange layer (DXL) application programming interface (API), the DXL API including instructions to communicatively couple the apparatus to a DXL bus and provide a DXL abstraction layer on top of a TCP/IP-based communication network; and a reputation engine including instructions encoded within memory to instruct the processor to: receive a plurality of DXL messages from a first DXL endpoint; compute a composite reputation for the first DXL endpoint; receive from a second DXL endpoint a DXL message requesting a reputation for the first DXL endpoint; establish a private topic on the DXL bus between the computing apparatus and the second DXL endpoint; and publish the composite reputation to the private topic.
