Fixed version of the CICFlowMeter tool

As part of our WTMC 2021 paper, we analysed and improved the CICFlowMeter tool, the result of which can be found in this repository. If you use this improved CICFlowMeter tool, please cite our paper:

        title={Troubleshooting an Intrusion Detection Dataset: the CICIDS2017 Case Study},
        author={Engelen, Gints and Rimmer, Vera and Joosen, Wouter},
        booktitle={2021 IEEE Security and Privacy Workshops (SPW)},
        pages={7--12},
        year={2021},
        organization={IEEE}
        }

A detailed list of all fixes and improvements, as well as implications of the changes can be found on our webpage, which hosts the extended documentation of our paper.

Here we stick to a brief summary of all changes to the CICFlowMeter tool:

  • A TCP flow is no longer terminated after a single FIN packet. It now terminates after mutual exchange of FIN packets, which is more in line with the TCP specification.

  • An RST packet is no longer ignored. Instead, the RST packet also terminates a TCP flow.

  • The Flow Active and Idle time features no longer encode an absolute timestamp.

  • The values for Fwd PSH Flags, Bwd PSH Flags, Fwd URG Flags and Bwd URG Flags are now correctly incremented.

Running the tool

To run the tool, please refer to the original CICFlowMeter repository for instructions.
