Dataset Card for NF-UNSW-NB15-v2

Note: Dataset is split following a 95 to 5% ratio by stratifying the attack type label.

Dataset Description

The NetFlow-based format of the UNSW-NB15 dataset, named NF-UNSW-NB15, has been expanded with additional NetFlow features and labelled with its respective attack categories. The total number of data flows is 2,390,275 out of which 95,053 (3.98%) are attack samples and 2,295,222 (96.02%) are benign. The attack samples are further classified into nine subcategories, the table below represents the NF-UNSW-NB15-v2 dataset's distribution of all flows.

Class	Count	Description
Benign	2,295,222	Normal unmalicious flows
Fuzzers	22,310	An attack in which the attacker sends large amounts of random data which cause a system to crash and also aim to discover security vulnerabilities in a system.
Analysis	2,299	A group that presents a variety of threats that target web applications through ports, emails and scripts.
Backdoor	2,169	A technique that aims to bypass security mechanisms by replying to specific constructed client applications.
DoS	5,794	Denial of Service is an attempt to overload a computer system's resources with the aim of preventing access to or availability of its data.
Exploits	31,551	Sequences of commands controlling the behaviour of a host through a known vulnerability
Generic	16,560	A method that targets cryptography and causes a collision with each block-cipher.
Reconnaissance	12,779	A technique for gathering information about a network host and is also known as a probe.
Shellcode	1,427	Malware that penetrates a code to control a victim's host.
Worms	164	Attacks that replicate themselves and spread to other computers.
