Security Onion is a Linux distro for intrusion detection, network security monitoring, and log management. It's based on Ubuntu and contains Snort, Suricata, Zeek, OSSEC, Sguil, Squert, Snorby, ELSA, Xplico, NetworkMiner, and many other security tools. The easy-to-use Setup wizard allows you to build an army of distributed sensors for your enterprise in minutes!

T-Pot is based on the network installer of Ubuntu Server 16/17.x LTS. The honeypot daemons as well as other support components being used have been containerized using docker. This allows us to run multiple honeypot daemons on the same network interface while maintaining a small footprint and constrain each honeypot within its own environment. Installation over vanilla Ubuntu - [T-Pot Autoinstall](https://github.com/dtag-dev-sec/t-pot-autoinstall) - This script will install T-Pot 16.04

The goal of Xplico is extract from an internet traffic capture the applications data contained. For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP), FTP, TFTP, and so on. Xplico isn’t a network protocol analyzer. Xplico is an open source Network Forensic Analysis Tool (NFAT).

OpenFPC is a set of tools that combine to provide a lightweight full-packet network traffic recorder & buffering system. It's design goal is to allow non-expert users to deploy a distributed network traffic recorder on COTS hardware while integrating into existing alert and log management tools.

netsniff-ng is a free Linux networking toolkit, a Swiss army knife for your daily Linux network plumbing if you will. Its gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa.

CollecTor, your friendly data-collecting service in the Tor network. CollecTor fetches data from various nodes and services in the public Tor network and makes it available to the world. If you're doing research on the Tor network, or if you're developing an application that uses Tor network data, this is your place to start.
