DoS201X Highly Unbalanced (Federated, Pre-Partitioned)

This dataset is a preprocessed, repartitioned derivative of the CIC-DDoS2019, CIC-IDS2018 and CIC-IDS2017 datasets, originally published by the Canadian Institute for Cybersecurity (CIC), University of New Brunswick.

More details about the CIC-DDoS2019 dataset can be found on this page and in the following scientific paper:

This version contains network flows partitioned per attack-type/client_id, converted from HDF5 to Parquet, and consolidated into three splits (train, val, test).

Dataset structure

Each split (train.parquet - ~80% of the whole dataset, val.parquet - ~10%, test.parquet - ~10%) contains one row per network flow sample, with the following columns:

Column	Type	Description
client_id	string	Attack-type / client partition the sample belongs to (e.g. "11-NetBIOS")
features	list<float32>	Flattened feature window; reshape to (10, 32) per sample to restore the original layout
label	int64	0 = benign, 1 = malicious

Samples are grouped by client_id, mirroring the original per-client HDF5 directory structure, used in the FLAD experimentation. The original HDF5 structure comprises 15 clients X 3 splits = 45 HDF5 files in the form of arrays of shape n = 10 rows and f = 32 columns. See this repository for more details.

Each client contains samples of benign traffic and only one type of attack. Although each group has been balanced to ensure an approximately equal distribution between benign and DDoS samples, the partition across groups/clients is strongly non-i.i.d since each one represents a single attack type.
