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.

Threat intelligence on a data exchange layer

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.

A silo rotary unloader monitor provides an indication of a rotational speed of the rotary collector ring of a material unloading device suspended within the top portion of a vertical silo. A limit switch has an actuating sensor biased into engagement with a sinusoidal cylindrical surface formed on a wheel mounted for rotation with the rotary collector ring. An electric circuit connected to the limit switch causes a remotely mounted electric signalling lamp or buzzer to flash or sound at a rate proportional to the rotary speed of the collector ring.
