Building risk analysis system with risk combination for multiple threats

A method for risk analysis, the method comprising:

• receiving a plurality of threats, the plurality of threats comprising a first threat and a second threat, the first threat and the second threat affecting a risk score of an asset;
• determining whether the first threat is correlated with the second threat;
• determining a value of the risk score to be a first value in response to a determination that the first threat is correlated with the second threat;
• and
• determining the value of the risk score to be a second value in response to a determination that the first threat is not correlated with the second threat.

A building management system comprising:

• one or more computer-readable storage media communicably coupled to one or more processors and configured to store instructions;
• and
• the one or more processors configured to execute the instructions to:
• receive a plurality of threats, the plurality of threats comprising a first threat and a second threat, the first threat and the second threat affecting a risk score of an asset;
• determine whether the first threat is correlated with the second threat;
• determine a value of the risk score to be a first value in response to a determination that the first threat is correlated with the second threat;
• and
• determine the value of the risk score to be a second value in response to a determination that the first threat is not correlated with the second threat.
