The raw network packets of the UNSW-NB151 dataset was created by the IXIA PerfectStorm tool in the Cyber Range Lab of the Australian Centre for Cyber Security (ACCS) for generating a hybrid of real modern normal activities and synthetic contemporary attack behaviours. Tcpdump tool used to capture 100 GB of the raw traffic (e.g., Pcap files). This data set has nine types of attacks, namely, Fuzzers, Analysis, Backdoors, DoS, Exploits, Generic, Reconnaissance, Shellcode and Worms. The Argus and Bro-IDS tools are used and twelve algorithms are developed to generate totally 49 features with the class label. a) The features are described here. b) The number of attacks and their sub-categories is described here. c) In this coursework, we use the total number of 10-million records that was stored in the CSV file (download). The total size is about 600MB, which is big enough to employ big data methodologies for analytics. As a big data specialist, firstly, we would like to read and understand its features, then apply modeling techniques. If you want to see a few records of this dataset, you can import it into Hadoop HDFS, then make a Hive query for printing the first 5-10 records for your understanding.
