In this chapter, we reviewed a set of very interesting types of attacks, including teardrop attacks, SYN flood attacks, and many types of DNS attack, as well as how to defend your infrastructure against them.

We also learned how to better deal with password-based attacks, not just from the user's point of view, but also from an enterprise point of view. Additionally, we learned how to create a DiD model and how to take advantage of layers to secure your data.

Finally, we concluded the chapter by understanding how you can leverage the benefits of having (or hiring) a blue or red team in your organization.

Now, let's move on to the next chapter, where we are going to understand how to manage risks on an enterprise level by leveraging the NIST cybersecurity framework. Also, we will see how to create a world-class BCP and DRP to enhance the availability and survivability of your organization.
