Protect MySQL Database from SQL injection attacks - GreenSQL

GreenSQL is an Open Source database firewall used to protect databases from SQL injection attacks. GreenSQL works as a proxy and has built in support for MySQL and PostgreSQL. The logic is based on evaluation of SQL commands using a risk scoring matrix as well as blocking known db administrative commands (DROP, CREATE, etc).

GreenSQL works as a reverse proxy for MySQL connections. This means, that instead of connecting TO THE MySQL server, your applications will connect to the GreenSQL server. GreenSQL will analyze SQL queries and then, if they're safe, will forward them to the back-end MySQL server.

Web Application Security Scanner by Google - Skipfish

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.

Keep in mind that all types of security testing can be disruptive. Although the skipfish scanner is designed not to carry out malicious attacks, it may accidentally interfere with the operations of the site. You must accept the risk, and plan accordingly. Run the scanner against test instances where feasible, and be prepared to deal with the consequences if things go wrong.

Use skipfish only against services you own, or have a permission to test.

Use skipfish at your own risk.

Framework to Find and Exploit web Application Vulnerabilities - w3af

You may use this tool at your own risk!

w3af is a Web Application Attack and Audit Framework which aims to identify and exploit all web application vulnerabilities.

The framework has been called the "metasploit for the web", but it's actually much more than that, because it also discovers the web application vulnerabilities using black-box scanning techniques!

The w3af core and it's plugins are fully written in Python. The project has more than 130 plugins, which identify and exploit SQL injection, cross site scripting (XSS), remote file inclusion and more.

Detail Memory Reporting Tool for Linux System - smem

smem is a tool that can give numerous reports on memory usage on Linux systems. Unlike existing tools, smem can report proportional set size (PSS), which is a more meaningful representation of the amount of memory used by libraries and applications in a virtual memory system.

Because large portions of physical memory are typically shared among multiple applications, the standard measure of memory usage known as resident set size (RSS) will significantly overestimate memory usage. PSS instead measures each application's "fair share" of each shared area to give a realistic measure.

Ubuntu based Penetration Testing Distribution - Blackbuntu

Blackbuntu is distribution for penetration testing which was specially designed for security training students and practitioners of information security.

Blackbuntu is Ubuntu base distro for Penetration Testing with GNOME Desktop Environment. It's currently being built using the Ubuntu 10.10 and work on reference Back|Track.
