NapierOne: A modern mixed file data set alternative to Govdocs1

It was found when reviewing the ransomware detection research literature that almost no proposal provided enough detail on how the test data set was created, or sufficient description of its actual content, to allow it to be recreated by other researchers interested in reconstructing their environment and validating the research results. A modern cybersecurity mixed file data set called NapierOneis presented, primarily aimed at, but not limited to, ransomware detection and forensic analysis research. NapierOnewas designed to address this deficiency in reproducibility and improve consistency by facilitating research replication and repeatability. The methodology used in the creation of this data set is also described in detail. The data set was inspired by the Govdocs1 data set and it is intended that NapierOnebe used as a complement to this original data set.
