Linux is often talked about when it comes to security. With this OS, you can choose from a multitude of distributions (distros) to lock down your computer or device, but that’s just for starters. Many Linux distros come with tools to help you perform penetration tests and security audits.
Take a look at just a few Linux distros for security testing. Many are based on Debian or Ubuntu with some added built-in custom tools.
Backbox, for instance, is an Ubuntu-based OS. It comes with a variety of pentesting and security assessment tools for network and systems analysis. These tools can perform such tasks as web application or network analysis, stress tests, sniffing, vulnerability assessment, computer forensic analysis or exploitation.
