In this chapter, you were presented with information about both kernel-specific security projects as well as external projects. Most of these were presented in a bad manner. You were also given information related to how various security subsystems and subgroups are keeping pace with various security threats and security project implementations.

In the next chapter, we will move on to another interesting subject. Here, I am referring to the virtualization area. You will find more about the meta-virtualization aspect later along with various virtualization implementations, such as KVM, which has gathered a huge track over the last few years and has established itself as a standard. I will let the other elements, which will be presented in the next chapter, be a secret. Let's now further explore the content of this book.
