Scan your Linux security with Lynis
Have you ever thought about how secure your Linux machine really is? There are numerous Linux distros, each with its own default settings, on which you run dozens of software packages with different version numbers, and numerous services running in the background, which we hardly know or care about.
To find the security posture—the overall security status of the software, network, and services running on your Linux machine—you could run a few commands and get bits and pieces of relevant information, but the amount of data you need to parse is huge.It would be so much better if you could just run a tool that generates a report on a machine’s security posture. And luckily there is one: Lynis. It is an extremely popular open source security auditing tool that helps with hardening Linux- and Unix-based systems.
Great tool well worth a try.
