Skipfish Web Application Security Scanner

To help assess web application security, Skipfish scanner is a very useful tool.

Skipfish is an active web application security reconnaissance tool. It prepares an interactive sitemap for the targeted site by carrying out a recursive crawl and dictionary-based probes. The resulting map is then annotated with the output from a number of active (but hopefully non-disruptive) security checks. The final report generated by the tool is meant to serve as a foundation for professional web application security assessments.

Key features:

High speed: pure C code, highly optimized HTTP handling, minimal CPU footprint – easily achieving 2000 requests per second with responsive targets.
Ease of use: heuristics to support a variety of quirky web frameworks and mixed-technology sites, with automatic learning capabilities, on-the-fly wordlist creation, and form autocompletion.
Cutting-edge security logic: high quality, low false positive, differential security checks, capable of spotting a range of subtle flaws, including blind injection vectors.

Skipfish is a command line tool, meaning you have to use terminal in Linux or command prompt in Windows to use it.

Basically you feed the command with options and the URL of the web application to check.

Please keep in mind that as it is emulating an attack, it may interfere with the web application operation.
