A computing system for monitoring, validating, and illustrating data transfer between computing devices in an enterprise computing system receives packet header information from network sensing modules. The computing system validates the records of the collected packet header information and discards erroneous records. The computing system corrects invalidly recorded information in the records. The computing system identifies records corresponding to unidirectional and bidirectional data transfer, generating a single data transfer record for a unidirectional data transfer and a pair of data transfer records for a bidirectional data transfer. The computing system stores the data transfer records in a standard data structure accessible at a user interface. The computing system generates a graphical directionality map for display at the user interface based on the input data transfer records to depict the data transfer relationships between computing devices.
