SecTools.Org: Top 125 Network Security Tools
For more than a decade, the Nmap Project has been cataloguing the network security community's favorite tools. In 2011 this site became much more dynamic, offering ratings, reviews, searching, sorting, and a new tool suggestion form. This site allows open source and commercial tools on any platform, except those tools that we maintain (such as the Nmap Security Scanner, Ncat network connector, and Nping packet manipulator).
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. Enjoy!
(10) ★★★★½ Nikto (#14, 2)
Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 6400 potentially dangerous files/CGIs, checks for outdated versions of over 1200 servers, and version specific problems on over 270 servers. It also checks for server configuration items such as the presence of multiple index files, HTTP server options, and will attempt to identify installed web servers and software. Scan items and plugins are frequently updated and can be automatically updated. Read 15 reviews.
Latest release: version 2.1.4 on Feb. 20, 2011 (11 years, 3 months ago).
This handy little utility assembles and sends custom ICMP, UDP, or TCP packets and then displays any replies. It was inspired by the ping command, but offers far more control over the probes sent. It also has a handy traceroute mode and supports IP fragmentation. Hping is particularly useful when trying to traceroute/ping/probe hosts behind a firewall that blocks attempts using the standard utilities. This often allows you to map out firewall rule sets. It is also great for learning more about TCP/IP and experimenting with IP protocols. Unfortunately, it hasn't been updated since 2005. The Nmap Project created and maintains Nping, a similar program with more modern features such as IPv6 support, and a unique echo mode. Read 4 reviews.
Latest release: version hping3-20051105 on Nov. 5, 2005 (16 years, 6 months ago).
Ettercap is a suite for man in the middle attacks on LAN. It features sniffing of live connections, content filtering on the fly and many other interesting tricks. It supports active and passive dissection of many protocols (even ciphered ones) and includes many feature for network and host analysis. Read 8 reviews.
Latest release: version 0.8.2-Ferri on March 14, 2015 (7 years, 2 months ago).
(2) ★★★★★ Sysinternals (#17, 7)
Sysinternals provides many small windows utilities that are quite useful for low-level windows hacking. Some are free of cost and/or include source code, while others are proprietary. Survey respondents were most enamored with:
- ProcessExplorer for keeping an eye on the files and directories open by any process (like lsof on UNIX).
- PsTools for managing (executing, suspending, killing, detailing) local and remote processes.
- Autoruns for discovering what executables are set to run during system boot up or login.
- RootkitRevealer for detecting registry and file system API discrepancies that may indicate the presence of a user-mode or kernel-mode rootkit.
- TCPView, for viewing TCP and UDP traffic endpoints used by each process (like Netstat on UNIX).
Many of the Sysinternals tools originally came with source code and there were even Linux versions. Microsoft acquired Sysinternals in July 2006, promising that “Customers will be able to continue building on Sysinternals' advanced utilities, technical information and source code”. Less than four months later, Microsoft removed most of that source code. Read 2 reviews.
Latest release: Feb. 4, 2011 (11 years, 3 months ago).
W3af is an extremely popular, powerful, and flexible framework for finding and exploiting web application vulnerabilities. It is easy to use and extend and features dozens of web assessment and exploitation plugins. In some ways it is like a web-focused Metasploit. Read 18 reviews.
Latest release: version 1.1 on Oct. 11, 2011 (10 years, 7 months ago).
(13) ★★★★★ Scapy (#20, 8)
Scapy is a powerful interactive packet manipulation tool, packet generator, network scanner, network discovery tool, and packet sniffer. Note that Scapy is a very low-level tool—you interact with it using the Python programming language. It provides classes to interactively create packets or sets of packets, manipulate them, send them over the wire, sniff other packets from the wire, match answers and replies, and more. Read 16 reviews.
Latest release: version 2.2.0 on Feb. 28, 2011 (11 years, 3 months ago).
While there are many advanced high-tech tools out there to assist in security auditing, don't forget about the basics! Everyone should be very familiar with these tools as they come with most operating systems (except that Windows omits whois and uses the name tracert). They can be very handy in a pinch, although more advanced functionality is available from Hping and Netcat. Read 3 reviews.
When you need to brute force crack a remote authentication service, Hydra is often the tool of choice. It can perform rapid dictionary attacks against more than 50 protocols, including telnet, ftp, http, https, smb, several databases, and much more. Like THC Amap this release is from the fine folks at THC. Other online crackers are Medusa and Ncrack. The Nmap Security Scanner also contains many online brute force password cracking modules. Read 25 reviews.
Latest release: version 8.2 on June 16, 2016 (5 years, 11 months ago).
no rating Perl/Python/Ruby (#23, 3)
While many canned security tools are available on this site for handling common tasks, scripting languages allow you to write your own (or modify existing ones) when you need something more custom. Quick, portable scripts can test, exploit, or even fix systems. Archives like CPAN are filled with modules such as Net::RawIP and protocol implementations to make your tasks even easier. Many security tools use scripting languages heavily for extensibility. For example Scapy interaction is through a Python interpreter, Metasploit modules are written in Ruby, and Nmap's scripting engine uses Lua. Review this tool.
(2) ★★½ Paros proxy (#24, 8)
A Java-based web proxy for assessing web application vulnerability. It supports editing/viewing HTTP/HTTPS messages on-the-fly to change items such as cookies and form fields. It includes a web traffic recorder, web spider, hash calculator, and a scanner for testing common web application attacks such as SQL injection and cross-site scripting. Read 6 reviews.
Latest release: version 3.2.13 on Aug. 8, 2006 (15 years, 9 months ago).
