Thanks to all [contributors](https://github.com/sbilly/awesome-security/graphs/contributors), you're awesome and wouldn't be possible without you! The goal is to build a categorized community-driven collection of very well-known resources.
* [OpenVAS](http://www.openvas.org/) - OpenVAS is a framework of several services and tools offering a comprehensive and powerful vulnerability scanning and vulnerability management solution.
* [Metasploit Framework](https://github.com/rapid7/metasploit-framework) - A tool for developing and executing exploit code against a remote target machine. Other important sub-projects include the Opcode Database, shellcode archive and related research.
* [justniffer](http://justniffer.sourceforge.net/) - Justniffer is a network protocol analyzer that captures network traffic and produces logs in a customized way, can emulate Apache web server log files, track response times and extract all "intercepted" files from the HTTP traffic.
* [httpry](http://dumpsterventures.com/jason/httpry/) - httpry is a specialized packet sniffer designed for displaying and logging HTTP traffic. It is not intended to perform analysis itself, but to capture, parse, and log the traffic for later analysis. It can be run in real-time displaying the traffic as it is parsed, or as a daemon process that logs to an output file. It is written to be as lightweight and flexible as possible, so that it can be easily adaptable to different applications.
* [ngrep](http://ngrep.sourceforge.net/) - ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
* [passivedns](https://github.com/gamelinux/passivedns) - A tool to collect DNS records passively to aid Incident handling, Network Security Monitoring (NSM) and general digital forensics. PassiveDNS sniffes traffic from an interface or reads a pcap-file and outputs
the DNS-server answers to a log file. PassiveDNS can cache/aggregate duplicate
DNS answers in-memory, limiting the amount of data in the logfile without
* [Snort](https://www.snort.org/) - Snort is a free and open source network intrusion prevention system (NIPS) and network intrusion detection system (NIDS)created by Martin Roesch in 1998. Snort is now developed by Sourcefire, of which Roesch is the founder and CTO. In 2009, Snort entered InfoWorld's Open Source Hall of Fame as one of the "greatest [pieces of] open source software of all time".
* [Bro](https://www.bro.org/) - Bro is a powerful network analysis framework that is much different from the typical IDS you may know.
* [Suricata](http://suricata-ids.org/) - Suricata is a high performance Network IDS, IPS and Network Security Monitoring engine. Open Source and owned by a community run non-profit foundation, the Open Information Security Foundation (OISF). Suricata is developed by the OISF and its supporting vendors.
* [Security Onion](http://blog.securityonion.net/) - Security Onion is a Linux distro for intrusion detection, network security monitoring, and log management. It's based on Ubuntu and contains Snort, Suricata, Bro, 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!
* [Dionaea](http://dionaea.carnivore.it/) - Dionaea is meant to be a nepenthes successor, embedding python as scripting language, using libemu to detect shellcodes, supporting ipv6 and tls.
* [Conpot](http://conpot.org/) - ICS/SCADA Honeypot. Conpot is a low interactive server side Industrial Control Systems honeypot designed to be easy to deploy, modify and extend. By providing a range of common industrial control protocols we created the basics to build your own system, capable to emulate complex infrastructures to convince an adversary that he just found a huge industrial complex. To improve the deceptive capabilities, we also provided the possibility to server a custom human machine interface to increase the honeypots attack surface. The response times of the services can be artificially delayed to mimic the behaviour of a system under constant load. Because we are providing complete stacks of the protocols, Conpot can be accessed with productive HMI's or extended with real hardware. Conpot is developed under the umbrella of the Honeynet Project and on the shoulders of a couple of very big giants.
* [Glastopf](http://glastopf.org/) - Glastopf is a Honeypot which emulates thousands of vulnerabilities to gather data from attacks targeting web applications. The principle behind it is very simple: Reply the correct response to the attacker exploiting the web application.
* [Kippo](https://github.com/desaster/kippo) - Kippo is a medium interaction SSH honeypot designed to log brute force attacks and, most importantly, the entire shell interaction performed by the attacker.
* [Kojoney](http://kojoney.sourceforge.net/) - Kojoney is a low level interaction honeypot that emulates an SSH server. The daemon is written in Python using the Twisted Conch libraries.
* [HonSSH](https://code.google.com/p/honssh/) - HonSSH is a high-interaction Honey Pot solution. HonSSH will sit between an attacker and a honey pot, creating two separate SSH connections between them.
* [Bifrozt](http://sourceforge.net/projects/bifrozt/) - Bifrozt is a NAT device with a DHCP server that is usually deployed with one NIC connected directly to the Internet and one NIC connected to the internal network. What differentiates Bifrozt from other standard NAT devices is its ability to work as a transparent SSHv2 proxy between an attacker and your honeypot. If you deployed a SSH server on Bifrozt’s internal network it would log all the interaction to a TTY file in plain text that could be viewed later and capture a copy of any files that were downloaded. You would not have to install any additional software, compile any kernel modules or use a specific version or type of operating system on the internal SSH server for this to work. It will limit outbound traffic to a set number of ports and will start to drop outbound packets on these ports when certain limits are exceeded.
* [HoneyDrive](http://bruteforce.gr/honeydrive) - HoneyDrive is the premier honeypot Linux distro. It is a virtual appliance (OVA) with Xubuntu Desktop 12.04.4 LTS edition installed. It contains over 10 pre-installed and pre-configured honeypot software packages such as Kippo SSH honeypot, Dionaea and Amun malware honeypots, Honeyd low-interaction honeypot, Glastopf web honeypot and Wordpot, Conpot SCADA/ICS honeypot, Thug and PhoneyC honeyclients and more. Additionally it includes many useful pre-configured scripts and utilities to analyze, visualize and process the data it can capture, such as Kippo-Graph, Honeyd-Viz, DionaeaFR, an ELK stack and much more. Lastly, almost 90 well-known malware analysis, forensics and network monitoring related tools are also present in the distribution.
* [tcpflow](https://github.com/simsong/tcpflow) - tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis and debugging. Each TCP flow is stored in its own file. Thus, the typical TCP flow will be stored in two files, one for each direction. tcpflow can also process stored 'tcpdump' packet flows.
* [Xplico](http://www.xplico.org/) - 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).
* [Rudder](http://www.rudder-project.org/) - Rudder is an easy to use, web-driven, role-based solution for IT Infrastructure Automation & Compliance. Automate common system administration tasks (installation, configuration); Enforce configuration over time (configuring once is good, ensuring that configuration is valid and automatically fixing it is better); Inventory of all managed nodes; Web interface to configure and manage nodes and their configuration; Compliance reporting, by configuration and/or by node.
* [google-authenticator](https://code.google.com/p/google-authenticator/) - The Google Authenticator project includes implementations of one-time passcode generators for several mobile platforms, as well as a pluggable authentication module (PAM). One-time passcodes are generated using open standards developed by the Initiative for Open Authentication (OATH) (which is unrelated to OAuth). These implementations support the HMAC-Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP) algorithm specified in RFC 6238.
