Cybersecurity Datasets:
11. DarkNet (CIC-Darknet2020)

Darknet is the unused address space of the internet which is not speculated to interact with other computers in the world. Any communication from the dark space is considered sceptical owing to its passive listening nature which accepts incoming packets, but outgoing packets are not supported. Due to the absence of legitimate hosts in the darknet, any traffic is contemplated to be unsought and is characteristically treated as probe, backscatter, or misconfiguration. Darknets are also known as network telescopes, sinkholes, or blackholes.

Darknet traffic classification is significantly important to categorize real-time applications. Analyzing darknet traffic helps in early monitoring of malware before onslaught and detection of malicious activities after outbreak.

This research work proposes a novel technique to detect and characterize VPN and Tor applications together as the real representative of darknet traffic by amalgamating out two public datasets, namely, ISCXTor2016 and ISCXVPN2016, to create a complete darknet dataset covering Tor and VPN traffic respectively.

In CICDarknet2020 dataset, a two-layered approach is used to generate benign and darknet traffic at the first layer. The darknet traffic constitutes Audio-Stream, Browsing, Chat, Email, P2P, Transfer, Video-Stream and VOIP which is generated at the second layer. To generate the representative dataset, we amalgamated our previously generated datasets, namely, ISCXTor2016 and ISCXVPN2016, and combined the respective VPN and Tor traffic in corresponding Darknet categories. Table 1 provides the details of darknet traffic categories and the applications used to generate the network traffic.

Table 1: Darknet Network Traffic Details

Traffic Category - Applications used:
Audio-Stream - Vimeo and Youtube
Browsing - Firefox and Chrome
Chat - ICQ, AIM, Skype, Facebook and Hangouts
Email - SMTPS, POP3S and IMAPS
P2P - uTorrent and Transmission (BitTorrent)
Transfer - Skype, FTP over SSH (SFTP) and FTP over SSL (FTPS) using Filezilla and an external service
Video-Stream - Vimeo and Youtube
VOIP - Facebook, Skype and Hangouts voice calls
