Summary

This chapter has covered foundational concepts in data security and the data handling requirements of sensitive information. In a nutshell, data can exist in three states. They are data in motion, data at rest, or data in use. The protection of data in any of these states is called Data Loss Prevention. Sensitive data needs special handling requirements as the compromise of such data would have devastating consequences.

The next chapter is a revision chapter for the first four chapters. References and further study on the first four chapters is provided. An exam cram as well as a mock test consisting of about 10 questions is also provided.
