1. A non-transitory computer readable medium including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for identifying controller anomalies, comprising:

  • monitoring data representing real-time processing activity of a controller;

    receiving comparable data relating to processing activity of at least one other controller deemed comparable in functionality to the controller;

    comparing the real-time processing activity data with the comparable data, to identify, based on a deviation between the real-time processing activity data and the comparable data, at least one anomaly in the real-time processing activity of the controller; and

    implementing a control action for the controller when the at least one anomaly is identified based on the deviation;

    wherein;

    software on the controller is mapped to a plurality of functional units, and the controller is configured to utilize a virtual file system (VFS) to manage and track one or more versions of each of the plurality of functional units, andthe control action includes updating memory addresses of one or more functional units managed by the VFS based on a delta file corresponding to a second version of the software on the controller, wherein the delta file comprises position-independent code and startup code for updating the memory addresses.
