In this chapter, we looked at the different data files used by NSE and the importance of using your own custom files. From now on, you will recognize opportunities to customize your scans to improve their effectiveness according to the environment. I also recommend that you start hoarding the common strings, usernames, and passwords you encounter in your daily life. It will prove very valuable further down the line.

In the next chapter, you will start learning about the NSE API and the available libraries that will make our lives easier. It is time you develop your very own script.
