In 2011 this site became much more dynamic, offering ratings, reviews, searching, sorting, and a. This site allows open source and commercial tools on any platform, except those tools that we maintain (such as the,, and ). We're very impressed by the collective smarts of the security community and we highly recommend reading the whole list and investigating any tools you are unfamiliar with. Click any tool name for more details on that particular application, including the chance to read (and write) reviews. Many site elements are explained by tool tips if you hover your mouse over them. Wireshark (known as Ethereal until a trademark dispute in Summer 2006) is a fantastic open source multi-platform network protocol analyzer. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, delving down into just the level of packet detail you need. Wireshark has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session. It also supports hundreds of protocols and media types. A -like console version named tshark is included. One word of caution is that Wireshark has suffered from dozens of remotely exploitable security holes, so stay up-to-date and be wary of running it on untrusted or hostile networks (such as security conferences). Latest release: version 1.12.7 on Aug. 12, 2015 (3 years, 4 months ago). • • • • • • • • • • • • • (#2, 3). Metasploit took the security world by storm when it was released in 2004. It is an advanced open-source platform for developing, testing, and using exploit code. The extensible model through which payloads, encoders, no-op generators, and exploits can be integrated has made it possible to use the Metasploit Framework as an outlet for cutting-edge exploitation research. It ships with hundreds of exploits, as you can see in their. This makes writing your own exploits easier, and it certainly beats scouring the darkest corners of the Internet for illicit shellcode of dubious quality. One free extra is, an intentionally insecure Linux virtual machine you can use for testing Metasploit and other exploitation tools without hitting live servers. Metasploit was completely free, but the project was acquired by in 2009 and it soon sprouted commercial variants. The Framework itself is still free and open source, but they now also offer a free-but-limited Community edition, a more advanced Express edition ($5,000 per year per user), and a full-featured Pro edition. Other paid exploitation tools to consider are (more expensive) and (less). The Metasploit Framework now includes an and also Raphael Mudge's excellent. The Community, Express, and Pro editions have web-based GUIs. Latest release: version 4.11 on Dec. 18, 2014 (3 years, 12 months ago). • • • • • • • • • • • • • (#3, 2). Nessus is one of the most popular and capable vulnerability scanners, particularly for UNIX systems. It was initially free and open source, but they in 2005 and in 2008. It now costs $2,190 per year, which still beats many of its competitors. A free “Nessus Home” version is also available, though it is limited and only licensed for home network use. Nessus is constantly updated, with more than 70,000 plugins. Key features include remote and local (authenticated) security checks, a client/server architecture with a web-based interface, and an embedded scripting language for writing your own plugins or understanding the existing ones.

It implements the best known cracking algorithms to recover wireless keys once enough encrypted packets have been gathered.. The suite comprises over a dozen discrete tools, including airodump (an 802.11 packet capture program), aireplay (an 802.11 packet injection program), aircrack (static WEP and WPA-PSK cracking), and airdecap (decrypts WEP/WPA capture files). Latest release: version 1.1 on April 24, 2010 (8 years, 7 months ago). • • • • • • • • • • • • • (#5, 2). This network intrusion detection and prevention system excels at traffic analysis and packet logging on IP networks. Through protocol analysis, content searching, and various pre-processors, Snort detects thousands of worms, vulnerability exploit attempts, port scans, and other suspicious behavior. Snort uses a flexible rule-based language to describe traffic that it should collect or pass, and a modular detection engine. Also check out the free, a web interface for analyzing Snort alerts.
