SECURITY RISK AGGREGATION AND ANALYSIS

Methods and apparatuses, including computer program products, are described for transaction-based security risk aggregation and analysis. A server computing device receives security risk data elements from a plurality of data sources. The security risk data elements correspond to a transaction submitted by a remote computing device to the server computing device for execution. The server computing device aggregates the security risk data elements into a weighted risk matrix and generates a risk score for the submitted transaction based upon the weighted risk matrix. The server computing device determines a business-level context and an execution priority of the submitted transaction, the business-level context and the execution priority based upon the security risk data elements. The server computing device adjusts the risk score for the submitted transaction based upon the business-level context and the execution priority and determines whether to allow execution of the transaction based upon the adjusted risk score.
