Table of contents


Network traffic

  • Unified Host and Network Dataset - The Unified Host and Network Dataset is a subset of network and computer (host) events collected from the Los Alamos National Laboratory enterprise network over the course of approximately 90 days. The host event logs originated from most enterprise computers running the Microsoft Windows operating system on Los Alamos National Laboratory's (LANL) enterprise network. The network event data originated from many of the internal enterprise routers within the LANL enterprise network.
  • Comprehensive, Multi-Source Cyber-Security Events - This data set represents 58 consecutive days of de-identified event data collected from five sources within Los Alamos National Laboratory's corporate, internal computer network.
  • User-Computer Authentication Associations in Time - This anonymized data set encompasses 9 continuous months and represents 708,304,516 successful authentication events from users to computers collected from the Los Alamos National Laboratory (LANL) enterprise network.
  • Canadian Institute for Cybersecurity datasets - Canadian Institute for Cybersecurity datasets are used around the world by universities, private industry and independent researchers.

  • 2017-SUEE-data-set - The data sets contain traffic in and out of the web server of the Student Union for Electrical Engineering (Fachbereichsvertretung Elektrotechnik) at Ulm University. Internal hosts are hosts from within the university network, some of them are cable bound, others connect through one of two wifi services on campus (eduroam and welcome). The data was mixed with attack traffic.
  • CTU-13 Dataset - A Labeled Dataset with Botnet, Normal and Background traffic.
  • PCAP files - Malware Traffic, Network Forensics, SCADA/ICS Network Captures, Packet Injection Attacks / Man-on-the-Side Attacks...
  • pcapt - Big repository of PCAP files.

  • UNSW-NB15 data set - This data set has nine families of attacks, namely, Fuzzers, Analysis, Backdoors, DoS, Exploits, Generic, Reconnaissance, Shellcode and Worms. The Argus, Bro-IDS tools are utilised and twelve algorithms are developed to generate totally 49 features with the class label.
  • Malware Training Sets - Today (please refers to blog post date) the collected classified datasets is composed by the following samples: APT1 292 Samples, Crypto 2024 Samples, Locker 434 Samples, Zeus 2014 Samples
  • The Drebin Dataset - The dataset contains 5,560 applications from 179 different malware families. The samples have been collected in the period of August 2010 to October 2012 and were made available to us by the MobileSandbox project.
  • Stratosphere IPS - Malware captures, Normal captures, mixed captures...
  • Microsoft Malware Classification Challenge - You are provided with a set of known malware files representing a mix of 9 different families. Each malware file has an Id, a 20 character hash value uniquely identifying the file, and a Class, an integer representing one of 9 family names.


  • Javascript Vulnerability dataset - Dataset constructed from the vulnerability information in public databases of the Node Security Project and the Snyk platform, and code fixing patches from GitHub.


  • West Point NSA Data Sets - Snort Intrusion Detection Log. Domain Name Service Logs. Web Server Logs. Log Server Aggregate Log.
  • Web Attack Payloads - A collection of web attack payloads.
  • Machine-Learning-driven-Web-Application-Firewall - Set of good and bad queries to a web application firewall.
  • Internet-Wide Scan Data Repository - The Censys Projects publishes daily snapshots of what we know about each IPv4 host, Alexa Top Million website, and known X.509 certificate. These datasets contain structured, non-ephemeral JSON records that identify a host's configuration.
  • 500K HTTP Headers - Recently we crawled the Top 500K sites (as ranked by Alexa). Following requests from readers we are making available the HTTP Headers for research purposes.
  • HTTP DATASET CSIC 2010 - The HTTP dataset CSIC 2010 contains thousands of web requests automatically generated. It can be used for the testing of web attack protection systems. It was developed at the Information Security Institute of CSIC (Spanish Research National Council).
  • ISOT datasets - The ISOT Lab has collected through different projects various datasets some of which are available for public sharing. ISOT Web Interactions Dataset (Mouse/Keystroke/Site Actions), ISOT Botnet Dataset...
  • Web Logs Secrepo - Web logs generated by secrepo community and secrepo web application
  • Common Crawl - The Common Crawl corpus contains petabytes of data collected over the last 7 years. It contains raw web page data, extracted metadata and text extractions.
  • Website Classification Dataset - The entire selective archive is manually curated, including classification of sites into a two-tiered subject hierarchy. We have made this manually-generated classification information available as an open dataset, in tab-separated column format.
  • AZSecure-data - The AZSecure-data PORTAL currently provides access to Web forums, Internet phishing websites, Twitter data, and other data.
