1. A system for detection and mitigation of cyberattacks on inter-bank financial transaction networks comprising:

  • an interface with an inter-bank financial transaction network, connected to an advanced cyber decision platform for mitigation of cyberattacks, the platform comprising;

    a computer system or network comprising at least one memory, at least one processor, and a first plurality of programming instructions comprising an operating system;

    a time series data store comprising at least a second plurality of programming instructions operating on the computer system or network which cause the computer system or network to;

    monitor a plurality of network events on the inter-bank financial transaction network;

    produce time-series data comprising at least a record of a network event on the inter-bank financial transaction network and the time at which the event occurred;

    an observation and state estimation module comprising at least a third plurality of programming instructions operating on the computer system or network which cause the computer system or network to;

    monitor a plurality of connected resources on the inter-bank financial transaction network;

    establish a baseline of expected behavior for each connected resource based on that resource'"'"'s activity on the inter-bank financial transaction network over a defined period of time; and

    produce a cyber-physical graph representing at least a portion of the plurality of connected resources, the cyber-physical graph comprising at least the logical relationships between the portion of the plurality of connected resources on the inter-bank financial transaction network, the physical relationships between any connected resources that comprise at least a hardware device, the expected behaviors for each connected resource, and any deviations from expected behavior for each connected resource;

    a directed computational graph module comprising at least a fourth plurality of programming instructions operating on the computer system or network which cause the computer system or network to;

    perform a plurality of analysis and transformation operations on at least a portion of the time-series data;

    perform a plurality of analysis and transformation operations on at least a portion of the cyber-physical graph; and

    produce a directed computational graph based on the analysis and transformation operations performed on the time-series data and the cyber-physical graph; and

    a transaction validator comprising at least a fifth plurality of programming instructions operating on the computer system or network which cause the computer system or network to;

    receive inter-bank financial transaction requests;

    analyze each transaction request based on the information contained in the directed computational graph;

    determine whether the transaction request is valid based on the analysis of the transaction request;

    if the transaction is determined to be valid, forward the transaction for completion; and

    if the transaction is determined to be invalid, deny the transaction and generate an alert or a change to the cyber-physical graph.
