Summary

We’ve reached yet another milestone in our journey, and we saw some cool stuff. We started with a discussion about the basics of setting up Snort as a NIDS. Then, I showed you how to seriously cheat by deploying a specialty Linux distro that already has a NIDS set up and ready to go. As a bonus, I showed you a quick and easy edge firewall appliance that comes with a built-in NIPS.

Next, I introduced you to Lynis and how you can use it to scan your system for various vulnerabilities and compliance issues. Finally, we wrapped things up with working demos of the Greenbone Security Assistant and Nikto.

In the next chapter, we’ll look at how to block certain applications from running. I’ll see you there.
