    Abstract: A building management system includes one or more computer-readable storage media having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to receive a threat, the threat comprising a particular threat type, the threat indicating an incident affecting a risk value associated with an asset. The instructions cause the one or more processors to determine, based on the threat and the asset, the risk value at a first point in time, select a decay model based on the particular threat type, and update the risk value at a plurality of points in time after the first point in time with the decay model causing the risk value to decay.

    Abstract: A system for securely communicating information in a building management system (BMS) includes a plurality of HVAC devices communicably coupled via a network each HVAC device storing a copy of an HVAC data chain that includes a plurality of blocks linked sequentially. The plurality of HVAC devices includes a first HVAC device including a processing circuit configured to generate a first block comprising device data and send the block to at least a portion of the plurality of HVAC devices. The processing circuit is configured to receive a second block from one of the plurality of HVAC devices and solve the second block. The processing circuit is further configured to add the solved block to the HVAC data chain of the first HVAC device as the newest block and send the solved block to each of the plurality of HVAC devices.

    Abstract: A building risk analysis system including one or more memory devices storing instructions thereon, that, when executed by one or more processors, cause the one or more processors to receive threats, each of the threats including a location, wherein each of the threats are threats of a particular threat category, determine a number of threats for each of geographic areas based on the location of each of the threats, and generate a distribution based on the number of threats for each of the geographic areas. The instructions further cause the one or more processors to determine a risk score for each of the geographic areas based on one or more characteristics of the distribution and the number of threats for each of the geographic areas.
