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!
Disassembly is a big part of security research. It will help you dissect that Microsoft patch to discover the silently fixed bugs they don't tell you about, or more closely examine a server binary to determine why your exploit isn't working. Many debuggers are available, but IDA Pro has become the de-facto standard for the analysis of hostile code and vulnerability research. This interactive, programmable, extensible, multi-processor disassembler has a graphical interface on Windows and console interfaces on Linux and Mac OS X. Review this tool.
Latest release: version 6.8 on April 13, 2015 (8 years, 5 months ago).
OllyDbg is a 32-bit assembler level analyzing debugger for Microsoft Windows. Emphasis on binary code analysis makes it particularly useful in cases where source is unavailable. OllyDbg features an intuitive user interface, advanced code analysis capable of recognizing procedures, loops, API calls, switches, tables, constants and strings, an ability to attach to a running program, and good multi-thread support. OllyDbg is free to download and use but no source code is provided. Read 2 reviews.
Latest release: version 2.01 on Sept. 27, 2013 (10 years ago).
(4) ★★★½ Immunity Debugger (#70, new!)
Immunity Debugger is a debugger whose design reflects the need to write exploits, analyze malware, and reverse engineer binary files. It builds on a solid user interface with function graphing, the industry's first heap analysis tool built specifically for heap creation, and a large and well supported Python API for easy extensibility. Read 6 reviews.
Latest release: version 1.80 on Dec. 6, 2010 (12 years, 10 months ago).
GDB is the GNU Project's debugger. Security folks use it to analyze unknown binaries, by getting disassemblies and stepping through a program instruction by instruction. GDB can debug programs written in Ada, C, C++, Objective-C, Pascal, and other languages. Review this tool.
Latest release: version 7.10 on Aug. 28, 2015 (8 years, 1 month ago).
WinDbg is a graphical debugger from Microsoft. It is actually just one component of the Debugging Tools for Windows package, which also includes the KD, CDB, and NTSD debuggers. Its claim to fame is debugging memory dumps produced after a crash. It can even debug in kernel mode. Read 1 review.
Latest release: version 10.0.10075.9 on April 29, 2015 (8 years, 5 months ago).
